A hydrostatic spherical thrust bearing with self-feedback throttling

Abstract

The invention discloses a static spherical thrust bearing with a self-feedback throttling function. The static spherical thrust bearing comprises a rotor, an upper bearing block, a lower bearing block and a spherical bearing, wherein a plurality of oil grooves, oil inlets and oil lines are formed in the spherical bearing. A self-feedback throttling way is adopted, and a throttler is not needed to be additionally provided, so that various problems brought by a small-hole throttler in the prior art are solved. The static spherical thrust bearing has the advantages of simple structure, low manufacturing cost, high bearing capacity and the like.

Description

technical field [0001] The invention relates to a static pressure spherical thrust bearing adopting self-feedback throttling, belonging to the field of thrust bearings. Background technique [0002] Traditional hydrostatic spherical thrust bearings widely use small hole throttling, capillary throttling and the combination of small hole and self-feedback throttling. For static pressure spherical thrust bearings with small hole throttling, because the inner diameter of the small hole restrictor is usually less than 0.3 mm, it is difficult to manufacture and the manufacturing cost is high, and because of the small inner diameter, it is prone to blockage. For the hydrostatic spherical thrust bearing of the capillary restrictor, since the capillary restrictor is usually long and the accessories are large and complicated, the manufacturing cost is high. Contents of the invention [0003] Purpose of the invention: Aiming at the above-mentioned prior art, a hydrostatic spherical ...
