Hybrid lubricating assembly

Abstract

The invention provides a hybrid lubricating assembly comprising a composite member and a shell, wherein the composite member comprises at least two unit members and is provided with an axle hole which axially penetrates through the composite member and enables an axle core to pass through; at least one group of multiple grooves communicated with the axle hole is arranged on at least one end face of at least one unit member in the composite member; the shell is provided with a hollow cavity perforative along an axial direction so as to accommodate the composite member; the outer wall of the composite member and the inner wall of the shell are encircled to form at least one storage chamber for storing lubricating media; and at least one group of multiple flow channels communicated with the axle hole and the at least one storage chamber is formed between at least one adjacent unit members of the at least one group of multiple grooves in the composite member.

Description

technical field [0001] The invention provides a hybrid lubricating assembly, in particular, at least one storage chamber for storing lubricating medium can be formed between the outer wall of the assembly and the inner wall of the housing, and the multi-channel dynamic pressure that can strongly support the rotation of the shaft core can be continuously formed. Mixed lubricating components with recirculating lubricating medium. Background technique [0002] Existing bearings operate in severe operating environments such as high temperature, low temperature, high load, high speed, and high vibration. Usually, after a short period of shaft core rotation, the shaft core may be directly contacted with the lubricating media due to the gradual consumption of the lubricating media. High-frequency knocking and collisions on the shaft hole wall will cause excessive wear and heat, which will eventually lead to abnormalities such as noise, shaft scraping, and hole expansion of the bear...

Problems solved by technology

[0007] The above-mentioned existing bearings have no special dynamic pressure and lubricating medium recovery mechanism design, lack of adjustability to the position and capacity of the lubricating medium flow channel and storage chamber, lack of flexibility in using multiple lubricating medium, and complex Therefore, there are limitations in applying it to severe operating conditions such as high temperature, low temperature, high speed, high load, and high vibration.
