Abstract

Field replaceable bearing and seal blocks for use in cleaning and other xerographic subsystem housings is disclosed. The bearing-seal blocks allow replacement of worn bearings and seals in the field without replacement of the entire cleaner housing. The blocks also allow the replacement of other cleaner internal components, for example, detoning rolls. The bearing-seal blocks also increase common parts usage in cleaner designs which reduces cleaner system hardware costs.

CLEANER HOUSING SEALS AND BEARINGS(C0nt'd)

Field replaceable bearing and seal blocks for use in cleaning and other xerographic subsystem housings is disclosed. The bearing-seal blocks allow replacement of worn bearings and seals in the field without replacement of the entire cleaner housing. The blocks also allow the replacement of other cleaner internal components, for example, detoning rolls. The bearing-seal blocks also increase common parts usage in cleaner designs which reduces cleaner system hardware costs.

A typical bearing block housing unit design consists of two endplates screwed to the ends of an extruded aluminum housing. The endplates are frequently molded plastic parts containing a number of threaded inserts, pins and one or more sets of ball bearings. Such designs are used for example on cleaners for XeroxTM 1075,1090,5090,5100 and other competitive cleaner and developer housings. The endplates can not normally be replaced in the field because alignments resulting from manufacturing assembly fixtures would be lost.

A replaceable unit is illustrated in the Figure. The unit maintains tolerances required for a functioning cleaner.
