Title:
THRUST BEARING AND TURBOCHARGER
Document Type and Number:
Japanese Patent JP2019078363
Kind Code:
A
Abstract:
To provide a thrust bearing which can inhibit a rapid pressure drop when lubrication oil flows from a land part into a taper part, and to provide a turbocharger.SOLUTION: A thrust bearing 4 includes slide surfaces 40f, 40r which are brought into slide-contact with a mating member 53 through an oil film and supports an axial thrust load acting on a rotary shaft 50. The slide surfaces 40f, 40r include multiple pad parts A each having a taper part B and a land part C. Each pad part A extends in a direction inclining relative to a circumferential direction and a radial direction. In between the pair of pad parts A located adjacent to each other in the circumferential direction, a downstream end Pc of the land part C of the upstream side pad part A and an upstream end Pb of the taper part B of the downstream side pad part A do not continue in the circumferential direction.SELECTED DRAWING: Figure 5
