Transmission
1. System description
This transmission is of the double reduction gear type. The
gears are a combination of helical and straight cut gears for
strength and low noise. The final drive gear is mounted on
opposing tapered roller bearings, and the intermediate gear is
mounted on ball bearings. Gears and bearings are enclosed
in an oil filled case. The drive motor is mounted externally
with the drive motor pinion gear mounted on the armature
shaft. The brakes are on the drive motor.
2. Troubleshooting
Because of the uncomplicated nature of this transmission,
troubleshooting is limited to identifying whether problems are
mechanical or electrical in nature. Fluid leaks are obviously
mechanical in nature and can be found by visual inspection.
Unusual noise and/or slow running could be mechanical or
electrical in nature. Generally speaking, if the problem is
caused internally in the transmission, then metal
contamination will be evident in the oil. If there is a
mechanical problem outside of the transmission, then it will
become evident by inspecting the drive motor and brakes.
