GENERAL INFORMATION:
Three specific units are described in this section. They are BRADEN part numbers 04713, 04714 and 04865. Refer
to the Specifications section for more detailed information on each unit.
All units are made up of the following sub-assemblies and parts:
1. Hydraulic motor
2. Static brake assembly and mechanical actuating mechanism
3. Two planetary gear sets sharing a common stationary ring gear.
4. Output pinion and bearing assembly
The static brake assembly is a multiple disc pack that is applied and/or released through a rotating mechanical
actuator. On the 04713 and 04714 units, a cable attached to the brake housing controls the internal actuating
mechanism. The brake is released when there is slack in the cable, and is applied by pulling on the cable. The
04865 unit is equipped with a spring loaded air cylinder in place of the cable. The brake is applied by the spring and
released by pressurizing the air cylinder.
The motor on all units is directly coupled to the input sun gear. The friction discs are splined to the input sun gear and
the solid spacer plates are pinned to the brake housing. In operation, the brake must be released for the hydraulic
motor to operate the drive in either direction. The motor drives through two planetary gear sets. The planet carrier of
the second stage gear set drives the output pinion. The ring gear for the planetary gear sets is stationary, resulting in
the output pinion turning in the same direction as the motor shaft.
