Claims

[Claims for Utility Model Registration] (1) A thrust receiving pad that is fitted onto the rotating main shaft through an axial hole and has thrust receiving pad surfaces on both sides in the axial direction can restrict the movement of the rotating main shaft in the axial direction; The pad has an oil supply hole extending in the radial direction from the axial hole, and further includes a plurality of pad grooves in which the pad surface communicates with the axial hole and extends radially, a pad contacting surface, and the pad groove and the pad contacting surface. In a thrust bearing having a pad groove formed between the oil supply hole and the shaft center hole, the passage cross-sectional area of the pad groove at a position close to the communication portion between the oil supply hole and the shaft center hole is made small, and the flow path area far from the communication portion is reduced. A thrust bearing characterized by a large passage cross-sectional area of the pad groove at the position. (2) A thrust receiving pad that is fitted to the rotating main shaft through an axial hole, is capable of restricting axial movement of the rotating main shaft by thrust receiving pad surfaces provided on both axial surfaces, and has a radial direction from the axial center hole. The pad surface has a plurality of pad grooves extending radially in communication with the shaft center hole, a pad contact surface, and a pad contact surface formed between the pad groove and the pad contact surface. 1. A thrust bearing having a pad and a tapered surface, characterized in that an axial hole is formed eccentrically toward the oil supply hole side with respect to the axial center of the thrust bearing.
