Description

Thrust bearing of centrifugal machine

Technical Field

The utility model relates to a footstep bearing device technical field, specifically speaking relate to centrifuge footstep bearing.

Background

A thrust bearing, also called a thrust bearing, is a special bearing for bearing axial forces, i.e. a bearing for forces in a direction perpendicular to the shaft. Thrust bearings are generally composed of two or more thrust washers and a plurality of rolling bodies, the thrust washers are generally divided into a shaft plate and a seat plate, and the rolling bodies are generally combined into a whole by iron or copper retainers in the most common mode. The most common type of bearing is a steel ball type thrust bearing, and the steel balls of the thrust bearing are easy to break and labor-consuming to repair and maintain.

Disclosure of Invention

An object of the utility model is to solve above-mentioned problem, provide centrifuge footstep bearing, it can form the oil film between footstep bearing's thrust tile and rotation axis to the thrust tile is difficult cracked.

In order to solve the above problem, the utility model discloses a technical scheme as follows:

thrust bearing of centrifuge, its characterized in that, including solid fixed ring, thrust tile, gu the fixed ring inboard is equipped with a plurality of fixed recesses, fixed recess is equipped with reference block and thrust tile in the inboard evenly distributed fixed slot of solid fixed ring, and the reference block is inboard at fixed recess, and the thrust tile is in the fixed recess outside, gu the first fixed pin in the radial outside of fixed ring is connected reference block and solid fixed ring, gu fixed ring radially is equipped with the oiling passageway, the oiling passageway is located on the solid fixed ring between two adjacent thrust tiles.

Furthermore, a flange plate is arranged on the outer edge of the fixing ring.

Furthermore, the thrust pad is provided with a temperature measuring hole in the radial direction, and a temperature measuring line is arranged in the temperature measuring hole.

Compared with the prior art, the utility model has the beneficial characteristics that:

lubricating oil is injected into the fixed ring, and in the high-speed rotating process of the rotating shaft, an oil film is formed in the gap between the rotating shaft and the thrust pad, so that the rotating shaft is lubricated and protected. In the rotating process of the rotating shaft, the thrust pads can rotate, and the thrust pads do not generate hard friction and collision with the rotating shaft, so that the abrasion of the thrust pads is reduced.
