Idler Shaft Assembly

The idler shaft is located on the left side of the machine and is just above the blower motor. The idler shaft assembly consists of one 11-inch (27.94 cm) drive wheel and two pillow block bearings.

Speed Reducing Shaft

The speed reducing shaft is located on the right side and is above the drive motor. The idler assembly consists of two idler pulleys. The idler’s main purpose is to reduce the speed and increase torque provided to the tumbler.

Drive Shaft

The drive shaft is located on the right side and is above the drive motor. The drive shaft consists of one 11-inch (27.94 cm) drive wheel, one pulley, and two pillow block bearings. The purpose of the drive shaft is to drive the tumbler.

Tumbler Shaft Support

The tumbler shaft support is located in the rear, approximately at the center of the dryer. The arrangement consists of a tumbler shaft support bracket, two high impact wheels, tumbler adjustment plate, Teflon® discs, and a rotational sensor assembly.

Rotational Sensor Assembly

The rotational sensor assembly is located in the rear of the dryer. It consists of a magnet and rotational sensor switch, which is mounted to the bearing cap. The magnet is screwed to the shaft.

The magnetic rotational sensor switch senses the rotation of the tumbler.

Tumbler

The tumbler consists of four ribs and four perforated panels, along with a front and back, which are welded together as an assembly. The tumbler also consists of a trunnion, which supports the tumbler in the rear.
