Abstract

The invention discloses an oil storage type Archimedes spiral end face anti-thrust sliding plate. The sliding plate comprises a bottom plate; a connecting column is disposed on the bottom plate; a through hole is formed in the middle of the connecting column; the section of the connecting column is composed of a plurality of Archimedes spiral segments; an annular oil groove is formed in the junction of the connecting column and the bottom plate; and holes communicating with the annular oil groove are formed in the junctions of the two Archimedes spiral segments. The Archimedes spiral face is arranged, so that lubricating oil package is good and the defect that lubrication is poor in the prior art is overcome.

Description

technical field [0001] The invention relates to the technical field of turbochargers, in particular to a thrust plate. Background technique [0002] The working environment of the turbocharger is relatively harsh, so the lubrication of the rotating device is very critical. If the lubrication is not good, the working state will be affected in the slightest, and the turbocharger will be damaged directly in the severe case. However, in the existing hole-shaft matching structure, the shafts are all cylindrical surfaces. The structural lubricating oil is limited by the gap between the hole and the shaft, and the amount is small. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a thrust sliding plate with better lubricating hole shaft combination, the specific technical scheme is as follows; [0004] An oil storage type Archimedes spiral end thrust sliding plate, including a bottom pl...
