MV37 Series High Torque Vane Motor 5 Technical data The MV37 series motors are hydraulically balanced internally and therefore no significant radial loads are induced on the motor bearings which contribute to long service life. The motor can be configured with various bearing options to accommodate external radial and axial loading. This data sheet details standard motors (see Figure 1); technically feasible, custom solutions may be offered. Please consult factory. Oil supply lines are connected to ports and on 2-port and double stack motor configurations and to 1, 2, 1 and 2 on 4-port configurations. Case drain lines can be installed on the port. Reference motor unit drawings on page 6 for additional case line locations and Case Drain section on page 4 for details. Using the port as the inlet will provide clockwise shaft rotation as seen from the front of the shaft. Using the port will provide counterclockwise shaft rotation also seen from the front of the shaft (see Figure 2 & Figure 3). The 4-port configuration has the front housing port designated 1, the center housing ports have been designated 2 and 1, and the rear housing port is designated as 2. This configuration can be used as a two speed motor with appropriate external valving. Like the motor with the single rotating group when inlet flow is provided to the 1 and 2 ports the motor shaft rotation will be clockwise as seen from the front of the shaft, and when inlet flow is provided to the 1 and 2 ports the motor shaft rotation will be counterclockwise as seen from the front of the shaft (see Figure 4).

8 High Torque Vane Motor MV37 Series Technical data Choice of hydraulic fluid osch Rexroth Rineer high torque vane motors are primarily designed to operate on conventional petroleum based hydraulic oils. The hydraulic oil can be chosen in consultation with the oil supplier or your local sales office, bearing the following requirements in mind: General The oil shall have FZG (9) fail stage minimum 11 described in IP 334 (DIN 51354). The oil must also contain inhibitors to prevent oxidation, corrosion and foaming. The viscosity of mineral oil is highly dependent on the temperature. The final choice of oil must depend on the operating temperature that can be expected at the motor or that has been established in the system and not in the hydraulic tank. Seals una N (NR) Temperature Range: 65 F to +25 F ( 54 C to +121 C) una N is a copolymer of butadiene and acrylonitrile with excellent compatibility with petroleum products. For exposure in low temperatures it is necessary to sacrifice some high temperature resistance. The product is superior in compression set, cold flow, tear, and abrasion resistance. Inferior in resistance to ozone, sunlight or weather. It is generally recommended for petroleum, water, diester, and water-glycol. Not recommended for use with halogenated hydrocarbons, phosphate ester, ketones, acids, and brake fluids. High temperatures in the system greatly reduce the service life of oil and rubber seals, as well as resulting in low viscosity, which in turn provides poor lubrication. Content of water shall be less than.1%. Oil used in the system should be filtered by a minimum of 25 micron filter. Fluid Cleanliness System Pressure < 3 psi / 27 bar > = 3 psi / 27 bar 19/17/14* 18/16/13 * ISO 446 Standard Fluorocarbon (FKM) (Viton) Temperature Range: 2 F to +35 F ( 29 C to +177 C) Viton is a linear copolymer of vinylidene fluoride and hexafluoro propylene which offers the widest temperature range and chemical resistance. The product is compatible and recommended for use with most fluids and gases such as petroleum, silicate ester, diester, halogenated hydrocarbons, and most phosphate esters. Viton has very good ozone, weather and aging resistance. It is not recommended for ketones, glycol based brake fluids, superheated steam, formic and acetic acids. Viscosity Minimum Operating Viscosity Maximum Operating Viscosity 1 SSU / 2 cst 25 SSU / 54 cst Disogrin (TODI/Polyurethane) Temperature Range: 54 F to +23 F ( 48 C to +11 C) Minimum operating viscosities must be met even at maximum temperature. Operating below 2 cst will result in reduced life expectancy. Maximum fluid temperature should not exceed 18 F (82 C). Please consult with a osch Rexroth Rineer pplications Engineer when using fire resistant fluid, water glycols, biodegradable fluids, or viscosities outside above recommendations. Disogrin is a high performance polyurethane. This compound is primarily used on O-rings for heavy duty applications and possesses extremely high mechanical properties, offering outstanding resistance to abrasion, tear and extrusion over a large range of temperatures. It has high temperature stability resulting in very low compression set required for sealing ensuring maximum service life. It is suitable for use with petroleum based fluids and some biodegradable (synthetic and natural Ester) fluids. osch Rexroth Corp., R 155, edition: 213-1
MV37 Series High Torque Vane Motor 9 Technical data osch Rexroth Rineer offers two types of rotary seals, namely a lip seal and quad ring seal designs in both NR and FKM materials. Radial lip seals accommodate external radial loads imposed on the shaft and higher speeds to a greater degree than quad seal designs. oth designs will accommodate axial loading on the shaft. Shaft seal options Seal Type Maximum Case Pressure External Loading Radial Lip Seal 35 psig (2.4 bar) Radial / xial Quad Seal 1 psig (6.9 bar) Low Radial / xial No Shaft Seal 5 psig (35 bar) N/ Heat failure of the material is the most common failure mode for a rotary seal. Reducing the friction at the shaft / seal interface is the most effective method of reducing heat build up on the seal. The higher the pressure to be sealed combined with high shaft speeds results in increased friction (heat buildup), decreasing seal life. Properly performing rotary seals offer unique challenges. Our seals operate with an oil film under the seal / shaft contact area that separates the two surfaces reducing surface wear and providing cooling to the contact area. Slippage oil which by-passes the vanes, rotor and timing plate interface accumulates in the case and lubricates the bearings and seals. When the motor is mated to a gearbox, bearing box, or overhung load adapter, it is possible to specify the motor to have no shaft seal which would allow motor case flow to flush the companion component. In this instance, the driven component must have a case connection to allow flow back to tank at a pressure low enough for the rating of its shaft seal. R 155, edition: 213-1, osch Rexroth Corp.
1 High Torque Vane Motor MV37 Series Technical data Selecting / Sizing a Motor Motor selection is dependent on the application and generally the required horsepower, motor speed range, and available supply pressure are to be defined. lternatively desired output torque and speed for a given application can be used. Motor speed (shaft speed) is a function of flow delivered to the motor and displacement. Torque output is a function of differential pressure and motor displacement. The charts illustrated are based on actual performance data and account for losses in a given motor. For example: n application requirement is 5 hp (37.28 kw) at 2 rpm with an available supply pressure of 32 psi (221 bar) and a return line pressure of 2 psi (14 bar). The pressure differential is 3 psi (27 bar).

4 High Torque Vane Motor MV37 Series Engineering guidelines Case Drain The 37 Series motors REQUIRE an external case drain of sufficient size to prevent back pressure in excess of 35 psi (2.4 bar) for radial lip seals or 1 psi (6.9 bar) for quad seals. case drain line must be run to the reservoir with minimum restriction as to not exceed the rated capacity of the seals; any unused case drain ports must be plugged. Never plug all case drain ports as this will cause build up of pressure in the motor case and blow out the shaft seal. The case drain line should return directly to the reservoir below the surface of the oil, and as far away as possible from the pump suction line. Refer to the unit drawings for case drain port locations. Use of the case drain port at the highest elevation is recommended. Thermal Shock Consideration to cold temperature environments must be provided in the event that a temperature differential exists between the motor and the system in excess of 5 F (28 C). Contact a osch Rexroth Rineer representative if this is a possibility. In cold temperature environments it may be necessary to warm up the oil in the hydraulic system before the system is used. Typically the warm up is limited to the oil, the pump and directional control valve; leaving other components in the circuit such as the motor cold. When a directional control valve is shifted, the warm oil in the hydraulic system flows through a cold motor resulting in a non-uniform expansion of the internal parts of the motor which may lead to galling and component failure. Low pressure oil can be circulated through the motor case at a maximum flow rate of 3 gpm (11 lpm) or idled at low speed of 2 rpm maximum until the motor temperature is within 5 F (28 C) or less than system oil temperature. osch Rexroth Corp., R 155, edition: 213-1
MV37 Series High Torque Vane Motor 41 Engineering guidelines Circuit design 2-port motor circuit When fluid flow is provided to the port, the rotation of the shaft as seen from its end will be clockwise. The port will be return line flow. Using the port for inlet flow will simply reverse the direction of rotation of the shaft and the port will become the return line port. Clockwise rotation Counter-clockwise rotation 4-port motor circuit The front housing has a port designated 1. The center housing has 2 each ports designated 2 and 1. Port 2 is on the same plane as port 1. Port 1 is offset from 2 by 9 degrees. The rear housing has a port designated 2 and is located on the same plane as 1 and Series/parallel circuit When using a series/parallel circuit with the 4-port motor, equal displacement rotating groups must be used. See the 2. The 4-ported motor is capable of single speed and with external valving, two speed operation. Two-speed operation with the 4-port motor can be accomplished using either series/parallel or logic circuits. circuit diagram below for reference only.
