Problems solved by technology

However, since the mesh grooves communicate with each other, the lubricating oil stored in the grooves will be squeezed out along the grooves, and the life of the friction pair is not significantly improved.
Vibration impact method can form mutually independent micropits on the working surface of the friction pair, but the wear of the tool head has a certain influence on the depth of the micropits, and it is not suitable for processing high hardness materials

Abstract

The present invention discloses a micropit numerical control laser forming method on the working surface of friction pair, and is characterized by that the components of the friction pair are rotated, the pulse laser bean can be used and relatively moved along the rotated components of the friction pair, then the focused pulse laser-bean can be used for making micropits on the working surface of friction pair components. Said invention possesses the following advantages: 1. can form micropits with thousands which are mutually independent and identical in depth on the working surface of frictino pair; 2. contactless processing, energy of laser beam and its movement can be regulated, and the rotating speed of components of friction pair also can be regulated; 3. it does not result in deformation of workpiece.

Description

technical field [0001] The invention relates to a surface processing method and a device, in particular to a numerically controlled laser forming method and a device for micropits on the working surface of a friction pair. Background technique [0002] In various friction pairs with relative motion, the working surface of the friction pair must form an oil storage structure to store lubricating oil, reduce friction and wear, and ensure the life of the motion pair. Flat-top honing and superfinishing are usually used as the final processing of the working surface of the friction pair to form a cross-groove flat-top oil storage structure; Carry out reverse electrolysis, form a network groove oil storage structure on the surface, and then honing process; or use vibration and impact processing to form mutually independent micro pits on the working surface of the friction pair, and then honing process. [0003] Both flat top honing and chrome plating of ...
