4 Catalogue HY070/UK esign Features and Benefits Rack and Pinion Maximum strength and shock resistance result from the use of throughhardened chrome alloy steel for the rack and for the onepiece pinion and output shaft. Gears are packed with molybdenum disulphide grease on assembly, to reduce wear and prolong gear life under conditions of extreme pressure. Bronze Rack Bearings Generous support for the rack is provided by a bronze rack bearing, reducing wear and extending pinion life. The bronze rack bearing, a standard feature on HTR models and above, is available as an option on smaller units. Gear Housing High strength ductile iron provides resistance to shock loads under the most arduous operating conditions. Four mounting holes in both the front and rear faces permit flexibility in machine design, with base and pilot mounting styles available as options. 6 6 Tie Rod Cylinders Proven tie rod construction, using standard cylinder bore sizes, guarantees reliability and ease of maintenance for the hydraulic cylinders which drive the rack and pinion. Heavywalled alloy steel tubing is microfinished for long piston and seal life, while tie rods are drawn from alloy steel, with precision rolled threads for high strength and resistance to fatigue. 7 Pistons and Seals Rugged onepiece steel pistons (not HTR.9 or HTR.8) are fitted as standard with polyurethane seals and PTFE wear rings, preventing metaltometal contact. The piston seals are selfcompensating for long life and reduced maintenance and, subject to access, seals and wear rings can be inspected or replaced without removing the actuator from the machine. 8 Cushioning Progressive deceleration is available by specifying cushions for either or both directions of rotation. The selfcentring cushions are adjustable, permitting exact matching to load and speed conditions, and offer extended machine life with reduced noise and shock Tapered Roller Bearings High capacity tapered roller bearings provide rigid support for the pinion and output shaft. Generous size and capacity allow the bearings to withstand external radial and thrust loads, even under high cycling applications. Correct bearing preload during maintenance is easily achieved by torque adjustment of the threaded retainer ring on the rear face of the rotary actuator, eliminating the inconvenience of shims and reducing the risk of damage to the bearing through incorrect adjustment. 9 8 Shaft Options plain male shaft with two keyways, the most widely used style of shaft, is supplied as standard with all HTR Series rotary actuators. The keyways are set at the and 6o'clock positions at midstroke for ease of positioning and assembly, and are as large as possible to ensure maximum strength. Shaft options include a female shaft with keyway, and male and female splined types. Both single and double shaft options are available, providing the greatest possible flexibility for the machine designer. 9 Floating Cushion Bushes Closer tolerances and therefore more effective cushioning are permitted by the use of floating cushion bushes. Lifting of the bronze cushion bush minimises fluid restriction to the start of the return stroke, allowing full pressure to be applied over the whole area of the piston, to provide full power and rapid cycle times. 4 Parker Hannifin Plc

10 Catalogue HY070/UK Cushioning Cushions and Cushion djustment Location Cushioning is recommended as a means of controlling the deceleration of masses. Machine life is extended as a result of the reduced shock, permitting faster cycle times with lower levels of noise. Cushions are recommended for high kinetic energy applications and/or where the full rotation of the actuator is being used. They are available as an option on all HTR Series rotary actuators, for one or both rotations, and do not affect the actuator's envelope or mounting dimensions. For the HTR Series rotary actuator, the standard angle of cushioning is 0 (0.49 rads). Formulae For a load that moves in the horizontal plane, only the kinetic energy need be considered. If the load is to move vertically, then the potential energy change of the load during cushioning must also be taken into account. Both conditions are described by the following equations. The resulting figure for energy to be absorbed can then be applied to the graph of Cushion Energy bsorption Capacity, to identify a rotary actuator with adequate cushion capacity. Note: the graph of Cushion Energy bsorption Capacity should only be used for initial sizing. For accurate sizing, please contact the factory. Each cushion is adjustable individually, allowing cushion performance to be matched to the application. The positions of cushion adjusters, relative to port positions, are shown in the table numbers relate to the diagram of port positions on page 8. * Single rack models only Port Position Cushion Position 4* For masses moving horizontally: E = Jm ω For masses moving downwards: E = Jm ω + mgrθ Note: Where cushioning is required on double rack units, the High Performance Cushion option described on page should be specified. For masses moving upwards: E = Jm ω mgrθ Floating Cushion Bush Cushion Spear Cushion djustment Needle Note that cushion performance will be affected by the use of high water content fluids. Please consult the factory for details. The energy absorption capacity of the cushion decreases with drive pressure, which in normal circuits is the relief valve pressure. Where: E = energy to be absorbed, Joules Jm = rotational mass moment of inertia, kgm ω = rotational velocity of load, rads/sec m = mass of load, kg g = acceleration due to gravity, 9.8m/s R = radius of rotation, m θ = angle of cushioning, radians (0.49 rads = 0 ) Example P = 00 m = 00 kg R = 0. m ω = 6 rpm Standard cushions = 0 = 0.49 rads. E = Jm ω + mgrθ E= x 00x0. x 6x π ( ] 60 ]) + (00 x 9.8 x 0. x 0.49) ] ] E = E = 8. Joules From the graph of Cushion Energy bsorption Capacity, it can be seen that an HTR7. (double rack unit) is capable of absorbing this energy where the High Performance Cushion option is specified. n HTR (single rack unit) is also capable of absorbing this energy. 0 Parker Hannifin Plc

11 Catalogue HY070/UK Cushioning High Performance Cushions The High Performance Cushion option can only be specified on double rack rotary actuators. ouble rack rotary actuators can achieve very high torques, which need to be decelerated at the end of the movement. This cushion energy is absorbed efficiently by the use of High Performance Cushions. External piping ensures that during cushioning the maximum deceleration torque is available. External interconnecting pipework for the High Performance Cushion is not supplied with the rotary actuator. Operation The work ports of a standard directional valve are connected directly to ports C and C of the rotary actuator, as shown. Port is connected directly to, and B is connected directly to B. When pressure is applied directly to port C (clockwise shaft rotation), fluid is also directed through line to the other rack. Exhaust flow from B and B is directed through the cushion bush and cushion adjustment screw until the cushion spear closes off the main passage. The total flow from both end caps is then directed across one cushion adjustment screw, equalizing back pressure and improving cushion performance. Pressurizing C and exhausting C reverses the operation. Notes. Pipework between and, and B and B should be kept to a minimum to reduce the inertia of the fluid. Fluid flow should be less than m/s.. Connection ports will have the same specification as the working ports.

12 Catalogue HY070/UK Piston Seals, Seal Kits and Stroke Limiters Piston Seals and Seal Kits The WearPak piston fitted as standard to all HTR Series rotary actuators employs a polyurethane seal to contain hydraulic pressure, and a PTFE wear ring (not for HTR.9 or HTR.8) to prevent metaltometal contact. For higher temperatures or use with synthetic fluids, FPM seals should be specified for the piston; for water glycol or high water content fluids, nitrile seals are available. Filtration Effective filtration is vital to the long life and satisfactory performance of a rotary actuator. If the piston seals of a rack and pinion rotary actuator are worn or damaged, fluid which leaks past the piston will enter the gear housing. become overpressurized. ny external leakage from the gear housing, therefore, is indicative of worn or damaged piston seals and these should be examined and, if necessary, replaced, at the earliest opportunity. Note: it is essential that all hydraulic lines are thoroughly flushed before connection to the rotary actuator. Steel Piston PTFE Wear Band Polyurethane seal In the event of internal leakage into the gear housing, the pressure relief valve will ensure that the housing does not Seal Class Standard V W Seal Polyurethan e FPM Materials Carboxilated Nitrile Wear Ring Filled PTFE Filled PTFE Filled PTFE FPM seals also include a backup washer.

For example, a FPM seal kit for a HTR will be PSKHTRV. Stroke Limiters Fine control of the end of travel points of the rotary actuator can be obtained by specifying stroke limiters. These operate by reducing the maximum travel of the actuator within preset limits of either or 0 in each direction. djustment within this range is infinitely variable and may be carried out by the user. Several types of stroke limiter are available the design illustrated is suitable for applications requiring infrequent adjustment. Stroke Limiters and Cushions stroke limiters may be combined with the cushioning devices shown on page 0. 0 stroke limiters cannot be combined with cushions. The addition of stroke limiters requires an increase in build length. On double rack units with cushions, the cushion is fitted to the upper rack and the stroke limiter to the lower. The increase in build length, for both single and double rack units, is shown as dimension in the table. Cushion performance may be affected by the addition of a stroke limiter.
