G. TUMBLER BEARING AND PULLEY ARRANGEMENT
The tumbler bearing and the pulley
arrangement is located (viewing from the rear
of the dryer) approximately at the upper center
of the dryer. The arrangement consists of a
pulley, bearing platform, and bearing, which
serve to adjust, drive, and support the tumbler.
H. IDLER BEARING
Viewing from the rear of the dryer, the idler assembly
is located approximately on the lower left hand side
of the dryer. The idler assembly consists of one (1)
compound pulley. The idlers main purpose is to
reduce the speed and increase the torque, provided
to the tumbler bearing. Also, the idler assembly
belt tension can be adjusted. AD-15 thru AD-30
requires a 9” x 2-1/2” pulley. AD-50 thru AD-75
requires a 14” x 3” pulley.
I. DRIVE MOTOR AND BLOWER MOTOR
The drive motor is located on the back, approximately lower center of the dryer. It sits on an adjustable
base, so that the motor can be easily adjusted to the left or right, up or down. On non-reversing dryers,
the blower end of the motor is connected to the impellor, a backward curved paddlewheel. The impellor
provides airflow in the dryer. It creates a vacuum, which pulls the hot air from the burner into the tumbler
through the lint screen and out the exhaust. On reversing dryers, there are two (2) motors, one (1) for the
drive and one (1) for the blower.
