Patent Searching and Data


Title:
COMPRESSOR
Document Type and Number:
Japanese Patent JP2012036841
Kind Code:
A
Abstract:

To prevent lubricating oil from being leaked through a gap between the bearing member of a bearing housing and a drive shaft to be discharged to an upper part of a rotor of a drive motor.

A sealing member (50) formed in a ring shape is fitted into a drive shaft (17) on a lower face side of a bearing housing (23). An inclined face (50a) is formed along a lower outer circumference edge in the sealing member (50). Also, a gap (50b) is formed by cutting a part in the circumference direction of the sealing member (50). In a holding member (52), an inclined face (52a) corresponding to the inclined face (50a) of the sealing member (50) is formed. Here, by being pressed to the lower face side of the bearing housing (23) while bringing the inclined faces (50a, 52a) into contact with each other, the inner diameter of the sealing member (50) is reduced, and the sealing member is held on the lower face side of the bearing housing (23) by the holding member (52).
