COMPONENT SYSTEM DESCRIPTIONS
The basket (tumbler) is supported and driven by eight (8) 11 inches diameter drive wheels.
Two (2) of these wheels are attached to 1 – 3/4 inches diameter idler shaft, while the other two (2)
are attached to a 1 – 3/4 inches diameter drive shaft. Each of the wheels is fastened to the shafts by
a keyless locking bushing. The Tran torque is made up of three pieces an inner collar, an outer
sleeve, and a locking nut. The inner and outer elements have matching opposite tapers. As a result,
when the nut is tightened, the Tran torque contracts onto the shaft and expands into the drive wheel
locking the wheel onto the shaft. No key is required.
The idler and drive shafts are each supported by two (2) 1 – 3/4 inch 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 basket (tumbler). The Drive shaft sticks out through the side
of the dryer and has a sprocket No.60 – 2 Attached to it with taper lock bushing. This sprocket is
connected to a helical geared motor.
The drive shaft is supported by two (2) 1 – 3/4 inch diameter pillow block bearings. These
pillow blocks sit on a slotted platform, and they can be moved forward and back by loosening or
tightening the bearing adjustment bolts. This movement is needed to maintain proper tension on the
sprocket that run from the helical geared motor idler to the drive shaft.
The helical geared motor sits on an adjustable base so that the helical geared motor can be
moved forward and back, allowing proper tension to be maintained on the sprocket.
The basket (tumbler) is made of 14 gauge stainless steel preferred panels, four (4) stainless
steel ribs, and two (2) outer basket / tumbler rings made of rolled steel angle iron that has turned on
a lathe for smoothness, The basket (tumbler) is a completely welded assembly so the perforated
panels are not removable.
The impeller (fan) used in the dryer model 325 lbs is a 17.7 inches diameter forwardly
inclined squirrel cage impeller (fan) wheel. That spins in a counterclockwise direction looking at
the top of the blower housing.
The impeller / fan shaft is mounted in two (2) 1 – 3/4 inches diameter pillow block bearings,
and the shaft is driven by two (2) B – section V – belts connected to the blower motor. The blower
motor is mounted on an adjustable base. The motor position can be easily adjusted so that proper
tension can be maintained on the V – belts.
