摘要 |
A large diameter portion of a rotating shaft is supported by an opening in a front housing via a radial bearing. An outer race of the bearing is in contact with an inner, rear surface of the housing as a shoulder portion of the opening. The inner surface is forwardly recessed, so that a small chamber is formed between the housing and the bearing unit. The housing has a stopper projection at a rear end of an opening to which a shaft seal unit is inserted. The projection is axially projected to a faced front surface of the large diameter portion of the shaft, while a seal chamber is formed between the shaft seal unit and the large diameter portion. The seal chamber is in communication with the small chamber. A plurality of circumferentially spaced grooves for holding lubricant are formed at the recessed surface for forming the small chamber.
