Different versions of motors are achieved by the use of different flanges, shafts, valves and integrated speed sensors. Features High pressures combined with small size and low weight Large speed ranges Broad viscosity and temperature ranges Reversible motors for 2- and 4-quadrant operation Fields of application Road construction machines as road rollers and pavers Agricultural machines and forestry technology as harvesters and forestry machines Street vehicles such as busses, trucks and special vehicles and above all in hydrostatic fan drives.

2 2/4 Bosch Rexroth AG Mobile Hydraulics External gear motors RE 14 26/1.5 Function If pressurized oil is fed into the motor, a torque can be obtained from the shaft leading out of the housing. Here, a distinction is made between motors that rotate on one direction and reversible motors. External gear motors that rotate in one direction These are of asymmetrical design, i.e. the high and low pressure sides are defined and not interchangeable at will. In this case, reversible operation is not possible. In order to ensure a high efficiency level, a special running-in method is used for motors. Leakage oil is discharged internally to the outlet side. Pressure loading of the outlet is limited by the shaft seal. Reversible external gear motors The displacement method in external gear motors is the reverse of the pump process. Reversible motors have a special feature, however. Their symmetrical construction means that the high or low pressure chambers are separate from the bearing and shaft seal chamber. The resulting leakage oil is routed through a separate oil drain gland in the housing cover. This oil drainage enables the motor to be subjected to load via the return line, which in turn allows the use of series connections. Due to the connection between the shaft seal and the low-pressure end, however, standard motors and pumps can only withstand a pressure of up to approx. 3 bar. p A The figure shows a reversible gear motor for 4-quadrant operation, i.e. both output and input torque in both directions. (Hydraulic motor becomes a pump if load reversal occurs.)

9 External gear motors RE 14 26/1.5 Mobile Hydraulics Bosch Rexroth AG 9/4 External gear motors with integrated valves, sensors T P Pages 31, 32 Gear motor with integrated, pilot-operated proportional pressure relief valve and rotary shaft seal relieved of load thanks to the three-chamber design. The use of gear motors without this relief of the rotary shaft seal is not recommended due to the loads from the oil return line, particularly when the oil is cold. The basis of this drive unit is a motor model F. The pilot proportional pressure relief valve is integrated in the rear end cover. This unit has the following advantages: No pipework necessary for the functioning of the prop. pressure relief valve Integrated pressure relief Fail-safe function in the event of power loss Drag speed virtually zero Motor speed prop. controllable Unaffected by pressure loads from the outlet Additional information see: Hydrostatic fan drives External gear motors with pressure relief valve p 1 return port pressure < 3 bar (1 bar at starting) Page 23 External gear motors with integrated speed sensor The DSM1-1 Hall-effect speed sensor was specially developed for tough use in mobile work machines. The sensor detects the speed signal of ferromagnetic gear wheels. In this process, as an active sensor, it supplies a signal with constant amplitude independent of the rotational speed. Due to its compact, sturdy design, the gear motor with integrated sensor is suitable for the applications such as Page 34 In fan drives for buses, trucks and construction machinery from 7 to 2 kw As a vibration drive for road rollers and road construction machinery For additional information see: Speed Sensor DSM RE

40 4/4 Bosch Rexroth AG Mobile Hydraulics External gear motors RE 14 26/1.5 Notes Filter recommendation The major share of premature failures in external gear motors is caused by contaminated pressure fluid. Since a warranty cannot be issued for dirt-related wear, we recommend a filter be used, which can reduce the degree of contamination to a permissible degree in terms of the size and concentration of dirt particles: Operating pressure [bar ] >16 <16 Contamination class NAS Contamination class ISO / 19/16 To be reached with β X = We recommend that a full-flow filter always be used. Basic contamination of the pressure fluid used may not exceed class 19/16 according to ISO 446. Experience has shown that new fluid quite often lies above this value. In such instances a filling device with special filter should be used. General The motors supplied by us have been checked for function and performance. No modifications of any kind may be made to the pumps; any such changes will render the warranty null and void! Motor may only be operated in compliance with permitted data (see pages 14 18). Technical data All stated technical data is dependent on production tolerances and is valid for specific marginal conditions. Note that, as a consequence, scattering is possible, and at certain marginal conditions (e.g. viscosity) the technical data may change. Characteristics When designing the external gear motor, note the maximum possible service data based on the characteristics displayed on pages 1 to 14. Additional information on the proper handling of hydraulic products from Bosch Rexroth is available in our document: General product information for hydraulic products RE 7 8. Leakage oil line A leakage oil line must be connected directly to the tank in reversible motors or motors stressed by run-back. Observe sufficient dimensions. Contained in delivery The components with characteristics as described under device measurements and ordering code, pages 19 39, are contained in delivery. Project planning notes Comprehensive notes and suggestions are available in Hydraulics Trainer, Volume 3 RE 281, Project planning notes and design of hydraulic systems. Where external gear motors are used we recommend that the following note be adhered to.
