COMPONENT SYSTEM DESCRIPTIONS
A. BASKET/TUMBLER DRIVE SYSTEM
The basket (tumbler) is supported and driven by eight (8) 11-inch diameter drive wheels.
Two (2) of these wheels are attached to 1-1/2-inch diameter idler shaft, while the other two (2)
are attached to a 1-1/2-inch 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) 1-1/2-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 shafts is supported by two- (2) 1-1/4-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.
B. BASKET/TUMBLER
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.
C. AIR BLOWER DRIVE SYSTEM
The impeller (fan) used in the Image S225 dryer is a 15-inch diameter forwardly Inclined
squirrel cage impeller (fan) wheel. spins in a counterclockwise direction looking at the back of
the blower housing.
The impeller / fan shaft is mounted in two (2) 1-3/8-inch 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.
