COMPONENT SYSTEM DESCRIPTIONS
A. TUMBLER DRIVE SYSTEM
The tumbler is supported and driven by four (4) 11-inch diameter drive wheels. Two (2) of these wheels are attached
to a 1-1/2” diameter idler shaft, while the other two (2) are attached to a 1-1/2” diameter drive shaft. Each of the
wheels is fastened to the shafts by a taper lock bushing. The taper lock is made up of three (3) pieces: an inner collar,
an outer sleeve, and a key. The inner and outer elements have matching opposing tapers. As a result, when the bolts
are tightened, the taper lock contracts onto the shaft and expands into the drive wheel hub locking the wheel onto the
shaft.
The idler shaft and drive shaft are each supported by two (2) 1-1/2” diameter pillow block bearings. These bearings sit
on slotted support channels and can be moved inward or outward by the adjustment bolts to raise or lower the tumbler.
The drive system consists of a shaft mounted pulley, two (2) V-belts, and a 3 hp (2.24 kW) drive motor. Belt tension
can be adjusted by tightening or loosening the gear reducer turnbuckle.
