DYNAMIC PRESSURE THRUST POROUS BEARING

摘要

PROBLEM TO BE SOLVED: To provide a porous bearing by which an excellent lubricating characteristic is obtained even in a service condition of receiving not only a radial load but also a thrust load. SOLUTION: In a porous bearing which receives a thrust load by an end surface part of a cylinder body and receives a radial load by an inner peripheral surface, a dynamic thrust porous bearing 1 is constituted in such a way that projecting parts 2 arranged in a radial shape to the bearing center are formed at least in three places of a thrust receiving end surface, and a taper part 3 is formed at least on one side of the projecting parts 2, and a recessed part 4 being a bottom part of the taper part 3 is provided, and a group 5 is formed in a position corresponding to the recessed part 4 on a bearing inner peripheral surface.
