Open type diamond tilting pad thrust bearing

Abstract

The invention discloses an open type diamond tilting pad thrust bearing. The open type diamond tilting pad thrust bearing comprises a movable disc and a static disc, wherein the movable disc comprisesan annular movable disc base body and diamond movable disc tiles; the static disc comprises a static disc base body, diamond static disc tiles, a tile gasket and a wave spring; the static disc base body is an annular frame body with a cavity; a plurality of diamond static disc tiles are evenly embedded in an end face of one side of the static disc base body; the diamond static disc tiles can obliquely swing in a circumferential direction of the static disc base body, a section of the part protruding out of the end face of the static disc base body is in a horseshoe shape, and the part is attached to the diamond movable disc tiles; the tile gasket is arranged on the bottom faces of the diamond static disc tiles in an attached and cushioned mode and used for bearing the diamond static disctiles; and the wave spring abuts against the position between the bottom face of the cavity of the static disc base body and the tile gasket. The service life of the bearing is greatly prolonged, thestarting torque of the bearing is reduced, the temperature resistance is high, a small-diameter bearing can be conveniently manufactured, and the requirement of small-diameter tool equipment such as an underground power drilling tool can be met.

Description

technical field [0001] The invention relates to the technical field of thrust bearings, in particular to an open diamond tilting pad thrust bearing. Background technique [0002] Currently, tilting pad thrust bearings are often used in rotating machinery with high thrust loads. Thrust loads are transferred from sliding parts to stationary parts through a hydrodynamic oil film. Tilting pad thrust bearings consist of a series of flat surfaces that slide on fixed inclined pads. The space between the flat surface and the inclined pad is filled with lubricating oil, which is sucked in due to the sliding of the flat surface. [0003] Tilting pad thrust bearings are more and more widely used, especially in downhole power drilling tools and other small-diameter tools and equipment, but the existing tilting pad thrust bearings still have low structural strength, large working torque, Defects such as short service life. [0004] Therefore, how to provide a tilting pad thrust bearin...
