A DRIVE MECHANISM OF A SUCTION ROLL INCLUDING A SPUR WHEEL GEAR AND AN OUTWARD MOUNTING PORTION FOR A STATIONARY SUCTION BOX

摘要

A drive mechanism of a suction or deflection adjustment roll having a spur wheel gear. For a suction roll, a stationary suction box may be guided outward through the drive mechanism to be coupled with a suction device. An external gear ring may be rigidly coupled to a driven or gear end of the roll to mesh with a driven pinion. The driven pinion may be driven via a drive shaft coupled to the driven pinion through a pair of enmeshed gears. The driven pinion and an end of the drive shaft coupled to the pinion may each include a self-adjusting bearing, each self-adjusting bearing being adjacently positioned and supported on a bearing journal. The self-adjusting bearing associated with the end of the drive shaft may exhibit radial play with respect to one of an inside diameter of the drive shaft or an outside diameter of the bearing journal, which may permit tilting of the pinion with respect to the bearing journal. Force transference may be improved by positioning the pair of enmeshed gears connecting the drive shaft and pinion between the adjacent self-adjusting bearings.
