specific Embodiment approach 1

[0029] Specific Embodiment 1: This embodiment is a film-oil composite lubrication method. The process is as follows: the surface of the workpiece is pretreated, and then a solid lubricating film is processed on the surface of the workpiece, and then the surface of the solid lubricating film is infiltrated with lubricating oil or on the solid lubricating film. Lubricating oil is injected into the friction interface to complete film-oil composite lubrication;

[0030] The solid lubricating film is a composite film composed of one or more of a soft metal film, a polymer material film, a layered structure material film, and a ceramic film; the soft metal film is gold, silver, lead, tin or indium The polymer material film is nylon, polytetrafluoroethylene or polyimide; the layered substance film is graphite, molybdenum disulfide, tungsten disulfide or boron nitride; the ceramic film is Al 2 o 3 , ZrO 2 、Si 3 N 4 , SiC, TiO 2 , WC or Cr 2 o 3 The lubricating oil is a type 1 o...

specific Embodiment approach 2

[0034] Embodiment 2: This embodiment differs from Embodiment 1 in that the workpiece surface is a gear tooth surface, a bearing ball surface, a bearing inner ring surface or a bearing outer ring surface. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0035] Embodiment 3: This embodiment is different from Embodiment 1 or Embodiment 2 in that the method for preparing the soft metal film is ion plating or ion implantation. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention provides a membrane-oil composite lubrication method and relates to a lubrication method. The invention aims to solve problems that requirements of high speed high load working condition and changing working conditions cannot be met when prior solid membrane lubrication or oil lubrication is used separately and material selection is limited and the lubrication effect is poor when the prior solid membrane lubrication and oil lubrication are in mixed use. The method includes processing a solid lubrication membrane after pretreatment of work piece surface; soaking the surface of the solid lubrication membrane with lubrication oil or injecting lubrication oil to the a friction interface of the solid lubrication membrane, so that membrane-oil composite lubrication is realized. According to the invention, the solid lubrication membrane is spaced with oil lubrication, so that abrasion of the solid lubrication membrane is slow down, the solid lubrication membrane is protected and the lubrication service lifetime is prolonged. Mutual complementation in lubrication is realized. Through solid lubrication membrane carrying, lubrication coordination of lubrication and vibration absorption of the lubrication oil is realized. Through the solid lubrication membrane carrying, the lubrication oil on the solid lubrication membrane flows so as to realize heat dissipation. The technical condition requirements are not high, the application range is wide and the lubrication effect is good.

Description

technical field [0001] The invention relates to a lubrication method. Background technique [0002] Friction and wear in mechanical equipment not only increases energy consumption and causes huge economic losses, but also reduces equipment life and increases safety hazards. Lubrication technology is an effective way to reduce friction and wear. In addition, lubrication technology can also reduce noise and reduce health damage to workers. [0003] Lubricating oil lubrication is the most common way of lubricating. Lubricating oil plays the role of lubricating, cooling, rust prevention and eliminating impact and load. Lubricating oil is suitable for high speed, but the lubricating oil has poor oxidation stability, is easy to evaporate, and the oil film will be destroyed when subjected to high load, and the service temperature is limited. [0004] Oil lubrication cannot meet the working environment such as heavy load and radiation. Solid film lubrication expands the field of l...
