2/40 Bosch Rexroth AG Mobile Hydraulics External gear motors RE 14 026/01.05
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 dis-
charged 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. Re-
versible motors have a special feature, however. pA
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 sepa-
rate 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 connec-
tion between the shaft seal and the low-pres-
sure end, however, standard motors and pumps
can only withstand a pressure of up to approx.
3 bar.
The figure shows a reversible gear motor for

4-quadrant operation, i.e. both output and input
torque in both directions. (Hydraulic motor be-
comes a pump if load reversal occurs.)

External gear motors with integrated speed sensor

The DSM1-10 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 integra-
ted sensor is suitable for the applications such as
– In fan drives for buses, trucks and construction machinery

from 7 to 20 kW
– As a vibration drive for road rollers and road construction
machinery

The coupling must not transfer any radial
or axial forces to the motor.
The maximum radial run out of shaft

spigot is 0.2 mm.
Refer to the fitting instructions provided

by the coupling manufacturer for details
of the maximum permitted shaft misalign-
ment.
2. Sleeve couplings Spline Mmax. V pmax.

coupling. The sleeve must be free to
move axially. The distance between the
motor shaft and drive shaft must be 2+1.
Oil-bath or oil-mist lubrication is

necessary.
3. Drive shaft with tang

For the close-coupling of the motors
to gearboxes, etc. the motors shaft has Model “F”
a special drive shaft with tang which min. 8 12
combines with a center coupling 3.
