1 Series 90 Axial Piston Motors Technical Information

2 Series 90 Family of Pumps and Motors Series 90 hydrostatic pumps and motors can be applied together or combined with other products in a system to transfer and control hydraulic power. They are intended for closed circuit applications. Series 90 variable displacement pumps are compact, high power density units. All models utilize the parallel axial piston / slipper concept in conjunction with a tiltable swashplate to vary the pump s displacement. Reversing the angle of the swashplate reverses the flow of oil from the pump and thus reverses the direction of rotation of the motor output. Series 90 pumps include an integral charge pump to provide system replenishing and cooling oil flow, as well as control fluid flow. Series 90 pumps also feature a range of auxiliary mounting pads to accept auxiliary hydraulic pumps for use in complementary hydraulic systems. A complete family of control options is available to suit a variety of control systems (mechanical, hydraulic, electric). Series 90 motors also use the parallel axial piston / slipper design in conjunction with a fixed or tiltable swashplate. They can intake/discharge fluid through either port; they are bidirectional. They include an optional loop flushing feature that provides for additional cooling and cleaning of fluid in the working loop. In the variable motors, hydraulic or solenoid-operated two-position control valves move the swashplate between minimum and maximum displacement positions.

9 Hydraulic Equations Helpful for Motor Selection The following equations are helpful when sizing hydraulic motors. Generally, the sizing process is initiated by an evaluation of the machine system to determine the required motor speed and torque to perform the necessary work function. Refer to Metric System: Vg n Input flow Q e = l/min 1000 η v BLN-9885, "Selection of Driveline Components," for a more complete description of hydrostatic driveline sizing. First, the motor is sized to transmit the maximum required torque. The pump is then selected as a flow source to achieve the maximum motor speed.

10 System Parameters Case Pressure Under normal operating conditions, case pressure must not exceed the continuous case pressure rating. Momentary case pressures exceeding this rating are acceptable under cold start conditions, but still must stay below the maximum case pressure rating. Operation with case pressure in excess of Speed Limits Rated Speed is the speed limit recommended at full power condition, and is the highest value at which normal life can be expected. In a machine propel application, maximum motor speed during unloaded, on-road travelling on level ground should not exceed this limit. Maximum Speed is the highest operating speed permitted and cannot be exceeded without reducing product life and risking immediate failure and loss of hydrostatic power (which may create a safety hazard). In a machine propel application, maximum motor speed must never exceed this limit during any these limits may result in external leakage due to damage to seals, gaskets, and/or housings. Case Pressure bar psi Continuous 3 44 Maximum (cold start) 5 72 T E condition (i.e., top speed downhill). In addition, applications must have a braking system, redundant to the hydrostatic transmission, which will stop and hold the vehicle should hydrostatic control be lost. Maximum with Special Hardware requires approval from Sauer-Sundstrand Application Engineering. Special unit hardware and/or special operating conditions may be required. Consult Bulletin BLN-9884 ( Pressure and Speed Limits ) when determining speed limits for a particular application.

11 Pressure Limits System pressure is the differential pressure between system ports A and B. It is a dominant operating variable affecting hydraulic unit life. High pressure, which results from high load, reduces expected life in a manner similar to many mechanical assemblies such as engines and gear boxes. There are load-to-life relationships for the rotating group and life predictions can be performed by Sauer- Sundstrand Application Engineering. Rated system pressure is the highest normally occurring system pressure which should be encountered during normal machine use. Motors should be sized so that the peak machine load can be developed at or below this pressure. In most applications, the pump pressure limiter setting should not exceed this value. Adequate hydrostatic system life will not be achieved if the system is runs at or near this pressure continuously. Maximum system pressure is the highest intermittent pressure allowed. It is determined by the maximum machine load demand, usually during acceleration or load spikes. Maximum pressure is assumed to occur usually less than 2% of the total operating time. Both the maximum and rated pressure limits must be satisfied to achieve the expected life. Continuous pressure is the pressure at which the hydrostatic system could operate continuously and still achieve acceptable hydrostatic life. This pressure level varies depending on operating speed, and on the life requirements for a particular application. While most mobile applications require system pressure to vary widely during operation, a "weighted average" pressure can be derived from a machine duty cycle. (A duty cycle is a means of quantifying the pressure and speed demands of a particular system on a percent time basis.) Once a duty cycle has been determined or estimated for a specific application, contact Sauer-Sundstrand Application Engineering for system life ratings for the application. All pressure limits are differential pressures (referenced to charge pressure) and assume normal charge pressure and no externally applied shaft loads. Pressure Limits bar psi Maximum Rated T E 11

12 Fluid Specifications Hydraulic Fluid Ratings and data for Series 90 products are based on operating with premium hydraulic fluids containing oxidation, rust and foam inhibitors. These fluids must possess good thermal and hydrolytic stability to prevent wear, erosion and corrosion of the internal components. These include premium turbine oils, API CD engine oils per SAE J183, M2C33F or G automatic transmission fluids, Dexron II or IIE (not Dexron III) meeting Allison C3 or Caterpillar TO-2 and certain agricultural tractor fluids. Hydraulic fluids per DIN 51524, part 2 (HLP) and part 3 (HVLP) are suitable. Fire resistant fluids are also suitable at modified operating conditions. For more information see Sauer-Sundstrand publication BLN-9887 or Refer to publication ATI-E 9101 for information relating to biodegradable fluids. It is not permissible to mix hydraulic fluids. Contact your Sauer-Sundstrand representative for more information. Temperature and Viscosity Temperature and viscosity requirements must be concurrently satisfied. The data shown at right assumes petroleum/mineral based fluids. The high temperature limits apply at the hottest point in the transmission, which is normally the motor case drain. The motor should generally be run at or below the continuous temperature. The maximum temperature is based on material properties and should never be exceeded. Cold oil will generally not affect durability of the transmission components, but it may affect the ability to flow oil and transmit power; therefore temperatures should remain 16 C (30 F) above the pour point of the hydraulic fluid. The minimum temperature relates to the physical properties of component materials. For maximum unit efficiency and bearing life the fluid viscosity should remain in the recommended viscosity range. The minimum viscosity should be encountered only during brief occasions of maximum ambient temperature and severe duty cycle operation. The maximum viscosity should be encountered only at cold start. Heat exchangers should be sized to keep the fluid within these limits. Testing to verify that these temperature limits are not exceeded is recommended.

13 Fluid And Filtration To prevent premature wear, it is imperative that only clean fluid enter the hydrostatic transmission circuit. A filtration system capable of controlling the fluid cleanliness to ISO 4406 Class 18/13 (SAE J1165) or better, under normal operating conditions, is recommended. The selection of a filter depends on a number of factors including the contaminant ingression rate, the generation of contaminants in the system, the required fluid cleanliness, and the desired maintenance interval. Filters are selected to meet the above requirements using rating parameters of efficiency and capacity. Filter efficiency may be measured with a Beta ratio 1 (β x ). For simple closed circuit transmissions with controlled reservoir ingression, a filter with a (β 10 ) ratio of 1.5 to 2 has been found to be satisfactory. For some open circuit systems, and closed circuits with cylinders being supplied from the same reservoir, a considerably higher filter efficiency is recommended. This also applies to systems with gears or clutches using a common reservoir. For these systems, (β x ) ratios of 10 to 20 are typically required. Since each system is unique, the filtration requirement for that system will be unique and must be determined by test in each case. It is essential that monitoring of prototypes and evaluation of components and performance throughout the test program be the final criteria for judging the adequacy of the filtration system. See publication BLN-9887 or for more information. Fluid Cleanliness Level ISO 4406 Class 18/13 Recommended Filtration Efficiency Suction Filtration β = 75 (β ) Charge Filtration β = 75 ( β ) T E 1 Filter β x -ratio is a measure of filter efficiency defined by ISO It is defined as the ratio of the number of particles greater than a given diameter ("x" in microns) upstream of the filter to the number of these particles downstream of the filter. 13

14 System Requirements Brake Warning The loss of hydrostatic drive line power in any mode of operation (e.g., forward, reverse, or "neutral" mode) may cause the loss of hydrostatic braking capacity. A braking system, redundant to the hydrostatic transmission and adequate to stop and hold the machine, must therefore be provided in case the condition should develop. Reservoir The reservoir should be designed to accommodate maximum volume changes during all system operating modes and to promote de-aeration of the fluid as it passes through the tank. A suggested minimum total reservoir volume is 5/8 of the maximum charge pump flow per minute with a minimum fluid volume equal to 1/2 of the maximum charge pump flow per minute. This allows 30 seconds fluid dwell for removing entrained air at the maximum return flow. This is usually adequate to allow for a closed reservoir (no breather) in most applications. Overpressure Protection Series 90 motors (as well as other system components) have pressure limitations. As Series 90 motors are not equipped with overpressure protection, it is necessary that relief valves or pressure limiters are present elsewhere in the high pressure circuit to protect components from excessive pressures. Series 90 pumps are designed with a sequenced pressure limiting system and high pressure relief valves. When the preset pressure is reached, the pressure limiter system acts to rapidly de-stroke the pump in order to limit the system pressure. For unusually rapid load application, the high pressure relief valve function is available to also limit the pressure level. Refer to publication BLN for more information. The reservoir outlet to the charge pump inlet should be above the bottom of the reservoir to take advantage of gravity separation and prevent large foreign particles from entering the charge inlet line. A 125 µm screen over the outlet port is recommended. The reservoir inlet (fluid return) should be positioned so that flow to the reservoir is discharged below the normal fluid level, and also directed into the interior of the reservoir for maximum dwell and efficient deaeration. A baffle (or baffles) between the reservoir inlet and outlet ports will promote de-aeration and reduce surging of the fluid. NOTE: For systems with relief valves only, high pressure relief valves are intended for transient overpressure protection and are not intended for continuous pressure control. Operation over relief valves for extended periods of time may result in severe heat build up. High flows over relief valves may result in pressure levels exceeding the nominal valve setting and potential damage to system components. Case Drain A case drain line must be connected to one of the case outlets (L1 or L2) to return internal motor leakage and loop flushing flow to the system reservoir. The higher of the two case outlets should be used to promote complete filling of the motor case. Since the motor case drain fluid is typically the hottest fluid in the system, it is advantageous to return this flow through the heat exchanger. 14

(B) Charge Flow Requirement - Motor Determine the motor speeds and the maximum system pressure. Referring to the accompanying figure, "Charge Flow Requirement - Series 90 Motor," determine the flow factor of the motor, FM Using the following equation, determine charge flow requirement for the Motor: QM = QM = FM x Frame Size 75 FM x Frame Size = Charge Flow Req d - Motor (gpm) = Charge Flow Req d -Motor (lpm) Flow Factor Fm min-1 (rpm) 3600 min-1 (rpm) 3000 min-1 (rpm) 2000 min -1 (rpm) 1000 min-1 (rpm) p psi p bar System Pressure P E (C) Total Charge Flow Requirements The total charge flow requirement (QT) is the sum of the flow requirements of each of the components in the system; namely: QT = QP + QM 1 + QM Q Auxiliary = Total Charge Flow Req'd 15

16 Product Features and Options Loop Flushing Series 90 motors may incorporate an integral loop flushing valve. Installations that require additional fluid to be removed from the main hydraulic circuit because of fluid cooling requirements, or circuits requiring the removal of excessive contamination, will benefit from loop flushing. A loop flushing valve will remove heat and contaminants from the main loop at a rate faster than otherwise possible. In series 90 motors, the current loop flushing relief valve design includes an orifice which controls flushing flow under most conditions. A combination of orifice size and charge pressure relief setting will produce a specific flushing flow. A number of orifice sizes are available, resulting in several different flushing flow rates as illustrated in the accompanying graph. Loop flushing flow between gpm (5 and 15 l/min) is generally suitable for most applications, but specific operating conditions may require more flow. The specific rate of flushing flow selected for an application will depend on the amount of fluid volume in the working loop, the number of motors in the circuit, and possibly other factors. Motor loop flushing flow must be considered in the calculation of total pump charge flow required, to ensure that charge pressure is not reduced excessively in any operating condition. See section titled "Charge Flow Requirements." WARNING Excessive motor loop flushing flow may result in the inability to build required system pressure in some conditions. Correct charge pressure must be maintained under all conditions of operation to maintain pump control performance in hydrostatic systems. NOTE: Consult your Sauer-Sundstrand representative if loop flushing will be required in a circuit which contains a flow divider / combiner. A remote loop flushing valve may be required.

18 Speed Sensor Series 90 motors are available with an optional speed sensor for direct measurement of motor output speed. This sensor may also be used to sense the direction of motor rotation. A special magnetic speed ring is pressed onto the outside diameter of the cylinder block and a Hall effect pulse pickup sensor is located in the motor housing. The sensor accepts supply voltage and outputs a digital pulse signal in response to the speed of the ring. The output changes its high/low state as the north and south poles of the permanently magnetized speed ring pass by the face of the sensor. The digital signal is generated at frequencies suitable for microprocessor based controls. This sensor will operate with a supply voltage of 4.5 to 15 VDC, and requires a current of 12 ma at 5.0 VDC under no load. Maximum operating current is 20 ma at 5VDC. Maximum operating frequency is 15 khz. Output voltage in High State (VOH) is sensor supply voltage minus 0.5 VDC, minimum. Output voltage in Low State (VOL) is 0.5 VDC, maximum. NOTE: It is not acceptable to energize the VDC ppu with 12VDC battery voltage; it must be energized by a regulated power supply. If it is desirable to energize the sensor with battery voltage, contact Sauer-Sundstrand for an optional speed sensor. Refer to PIB 9602M. The sensor is available with a Packard Weather- Pack 4-pin sealed connector or Turck Eurofast M12x1 4-pin connector. NOTE: Strain relieve and / or protective cover installation with this device is required by the customer. NOTE: System FMEA must be done by the customer for each application with the help of Sauer- Sundstrand Application Engineering.

21 Loading, Life, and Efficiency External Loading and Bearing Life Bearing life is a function of several operating conditions including shaft speed, system pressure, swashplate angle, fluid viscosity, fluid cleanliness and external loading. The bearing will not limit motor life to less than hours (B-10) at rated speeds for any duty cycle assuming proper fluid conditions are maintained and no external loads are present. Particle contamination and poor viscosity reduce the life of bearings. External radial forces on the shaft transfer to the bearing and are additive to the internal bearing loads. The net effect on bearing life is thus a function of the orientation as well as the magnitude of the external shaft load. Maximum allowable external shaft load (R e ) is determined from the maximum allowable bending moment (M e ) in the Allowable Loading Table, given as a function of orientation per External Load Orientation figure. R e M e L T in T out Loading Parameters Maximum Radial Side Load Maximum External Moment Distance from Mounting Flange to Point of Load Maximum Thrust Inward Maximum Thrust Outward L R e T in T out T E R e = M e /L Although shaft deflection increases, bearing life can be optimized by orientating the external load so that it is not additive to the internal loading. To offset the internal bearing loads and optimize bearing life, the external load should be oriented at around 180 if possible. Loading 0 Re End View of 90 Re 270 Re P E External overhung adapters (or outboard bearings) are recommended for installations with high radial and/or axial loads. Tapered input shafts or "clamp type" couplings are recommended for installations where radial shaft loads are present. Splined shafts are typically not recommended installations where radial loads are present. Please contact your Sauer-Sundstrand representative for a bearing life analysis if: continuously applied external radial load exceeds 25% of the maximum allowable. design life is greater than hours. Provide information on location and direction of the external load.
