A rotary shaft sealing system

摘要

The invention relates to a flinger device (310) for preventing the ingress of foreign matter such as dust or grit to the vicinity of a contact surface between a rotary shaft lubricant seal (314) and the shaft (312). The device is adapted to locate on an end of the shaft and has a radially extending flange portion (342) which fits closely adjacent to a radially extending outer end surface (352) of a means (330) for retaining the seal in contact with the shaft. The device also has an axially extending wall part whose outer circumferential surface locates closely adjacent to an axially extending inner surface (338) of the seal retaining means. The surfaces of the flange portion and wall part of the device co-operate to prevent or at least restrict the ingress of foreign matter to the vicinity of the seal/shaft contact surface. <IMAGE>
