Title:
ROTARY APPARATUS
Document Type and Number:
Japanese Patent JP2016217476
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technology for suppressing destabilization of a dynamic pressure of a rotary apparatus.SOLUTION: The rotary apparatus includes a shaft body 6 including a shaft 110, and a bearing body 8 including a shaft surrounding member 42 surrounding the shaft 110. At least one of the shaft body 6 and the bearing body 8 is provided with a dynamic pressure generation groove 50 for generating a radial dynamic pressure to a lubricant 20 existing in its radial clearance. The bearing body 8 is provided with an axially extending communication passage BP on a position surrounding the dynamic pressure generation groove 50. One of the bearing body 8 and the shaft body 6 is provided with an axially extending inner communication passage 160 on a position deviated from the rotating shaft R in a radial direction and on an inner position of the communication passage BP. The inner communication passage 160 is constituted to communicate, in the radial clearance, a region at an axially outer side with respect to one end of a formation region of the dynamic pressure generation groove 50 with a region at an axially outer side with respect to the other end.SELECTED DRAWING: Figure 2
