Heavy-load bearing

Abstract

A heavy-load bearing comprises an assembly and a shell, wherein the assembly consists of at least two elements, and a shaft hole which penetrates through the assembly in the axial direction, is formed in the assembly to allow a shaft core to penetrate. The peripheral wall surface of each element is provided with an assemble part, two ends of each element are provided with two connecting parts, and each element is provided with a core hole which penetrates in the axial direction. At least one element of the assembly is concavely provided with at least one cavity slot in the axial direction in at least one of the two connecting parts, so the cavity slot is arranged between an outer wall adjacent to the assemble part and an inner wall adjacent to the core hole in a surrounding way. At least one element of the assembly is annularly provided with a group of multiple grooves at the free end of the inner wall, and the group of multiple grooves communicates the at least one cavity slot with the core hole. The shell is provided with a cavity which is extended in the axial direction for accommodating the assembly, at least one storage chamber for storing lubricating media is formed in a surrounding way by the at least one cavity slot between adjacent elements, and the at least one group of multiple grooves forms at least one group of multiple runners, between at least two adjacent elements in the assembly, and the at least one group of multiple runners communicates the shaft hole with the at least one storage chamber.

Description

technical field [0001] The present invention provides a high-load bearing, especially one that can form at least one storage chamber for storing lubricating medium by surrounding the cavities and grooves between adjacent units, and continuously form multi-channel dynamic pressure and circulation that strongly supports the rotation of the shaft core. Highly loaded bearings that recycle lubricating media. Background technique [0002] Existing bearings operate under harsh 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 lubricating media may be gradually exhausted, causing the shaft core to directly High-frequency knocking and collision with the wall of the shaft hole will cause excessive wear and heat, which will eventually lead to abnormalities such as noise, shaft scraping, and hole expansion of the bearing and accelerated damage. This is an urgent solution ...

AI Technical Summary

Problems solved by technology

[0007] All the existing bearings mentioned above have no recovery mechanism of dynamic pressure and lubricating medium, lack of adjustability to the position and capacity of the flow path of lubricating medium and storage chamber, lack of flexibility in using diversified lubricating medium, and reduce the amount due to complex structure Productivity; therefore, it has its limitations when applied to severe operating conditions such as high temperature, low temperature, and high speed. However, under high load and high vibration operating conditions, the strength of the overall structure is more important.
