Axial sliding mechanism

Abstract

The invention discloses an axial sliding mechanism and relates to the field of sliding mechanisms, aiming to solve the problems of complex structure, tedious processing, difficulty in control, too high cost, and greasy dirt pollution of the axial sliding mechanism. The mechanism comprises a shaft (1), a shaft sleeve (2), a lubricating ring sleeve (3) and an annular groove (4), wherein the lubricating ring sleeve (3) is sleeved on the exterior of the shaft (1) and is an open ring structure, the external diameter of the lubricating ring sleeve (3) in a natural open state is larger than the internal diameter of the shaft sleeve (2), and the annular groove (4) is also can be formed in the shaft (1); the lubricating ring sleeve (3) is embedded in the annular groove (4), and the lubricating ring sleeve (3) is made of a self-lubrication material and can be made of teflon or nylon. The axial sliding mechanism disclosed by the invention is applicable to various precision equipment or instruments.

Description

technical field [0001] The invention relates to the field of sliding mechanisms, in particular to a self-lubricating axial sliding mechanism. Background technique [0002] In the existing design of the sliding mechanism of the mechanical structure, when the sliding part and the fixed part are both shaft parts, the solution is generally that the sliding part and the fixed part are connected in the form of a shaft and a bushing and can slide with each other. At the same time, the following Method to reduce sliding resistance: [0003] 1. Improve the machining accuracy of the matching dimensions of sliding parts and fixed parts; [0004] 2. Reduce the surface roughness of the contact surface between the sliding part and the fixed part; [0005] 3. Thin oil, dry oil, solid and gas lubrication are used to lubricate the contact surface between the sliding part and the fixed part to ensure smooth movement of the sliding part and reduce friction loss. [0006] Such measures have ...

Problems solved by technology

[0007] 1. Complex structure;

[0008] 2. The processing technology of parts is cumbersome;

[0009] 3. High processing cost;

[0010] 4. Difficult to control sliding damping;

[0011] 5. It is not suitable for specific situations where low-speed sliding and high sliding damping control requirements are required

[0012] At present, the implementation method of low-cost self-lubricating axial sliding mechanism that can overcome the above shortcomings has never been found in the market, and no relevant patents and documents have been found after searching.
