Xerox Disclosure Journal
An oil impregnated felt ring for motor bearing lubrication and related applications is disclosed. A felt ring 1 saturated with an appropriate weight machine oil lubricant is fitted to a grooved area 2 within an idler roll 3 as shown in Figure 1. The felt ring oil dispenser 1 may also be used for continuous lubrication in related wrap spring clutch of assemblies typically found in document handler modules of many electrophotographic copiers as shown in Figure 2. A hub 5 with external groove 6 accommodates an oil saturated felt ring 1 or strip that prevents the wrap spring 4 from sticking to hub 5. The oil impregnated felt ring 1 is useful for gradual and continuous release of lubricant which reduces machine noise, parts wear and component failure.
