Gear Reducer
The gear reducer transfers torque to the auger. The auger drive motor turns the input shaft
of the gear reducer at a high rate of speed. The input shaft turns a worm (screw type gear)
that meshes with a worm gear (bronze gear). The worm gear turns the output shaft at a
reduced speed.
The gear reducer should
be inspected for oil
leakage, noise, and
vibration during
scheduled maintenance
of the machine. If the
gear reducer is noisy,
vibrating or seizing, the
oil level may be low,
internal parts may be
worn, or the gear
reducer may be under
excessive load due to a
problem in the
evaporator. If a problem
is found with the gear
reducer, it must be
replaced.
Mounting
Bracket
Output Shaft
If the gear reducer is
damaged, it may bind or
lock up causing the
auger motor to shut off
on overload. This is
usually caused by a
damaged worm gear due
to lack of lubricant or
excessive loading of the gear reducer.
Input Shaft
Note: The are no serviceable parts available for the gear reducer. The 9171010-03 Gear
Reducer is a sealed component and does not require service.
Coupler
The coupler is a three piece assembly used to connect the gear
reducer to the auger. The coupler includes the upper half, lower half
and the nylon “spider” which fits between the teeth of the coupling
halves, preventing metal to metal contact of the coupling teeth.
There should be an 1/8 inch gap between the coupler halves. The
“spider should fit tightly between the coupling teeth. If there is
excessive play between the coupling halves, the “spider” should be
inspected for wear and replaced.
