L.TUMBLER (Basket) SYSTEM
1.Tumbler Drive System
The tumbler (basket) is supported and driven by four (4) 11-inch diameter drive wheel assemblies. 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 trantorque keyless locking bushing. The trantorque is made up of three (3) pieces; an inner collar, an outer sleeve, and a locking nut. The inner and outer elements have matching opposing tapers. As a result, when the nut is tightened, the trantorque contracts onto the shaft and expands into the drive wheel hub locking the wheel on to the shaft. No key is required.
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. This results in raising or lowering the tumbler (basket).
The drive system consists of a shaft mounted gear reducer, two (2) V-belts, and a 5 HP drive motor. Belt tension can be adjusted by tightening or loosening the gear reducer turnbuckle.
To keep the tumbler (basket) in the middle of the dryer a series of retaining wheels are used in the front and rear of the dryer. The retaining wheels run along the vertical edge of the tumbler (basket) rings. These keep the tumbler from rubbing on the front and rear panels of the dryer.
