specific Embodiment approach 1

[0026] Specific embodiment 1: This embodiment is a film-grease composite lubrication method, the process is as follows: the surface of the workpiece is pretreated, then a solid lubricating film is processed on the surface of the workpiece, and then grease is coated on the surface of the solid lubricating film or on the solid lubrication Grease is injected into the friction interface of the membrane to complete the membrane-grease compound lubrication;

[0027] 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 material 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 grease is a composite titanium-based grease, a...

specific Embodiment approach 2

[0031] Embodiment 2: This embodiment is different 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 in the first embodiment.

specific Embodiment approach 3

[0032] Embodiment 3: This embodiment is different from Embodiment 1 or 2 in that the method for preparing the soft metal film is an ion plating method or an ion implantation method. Other steps and parameters are the same as those in the first or second embodiment.

Abstract

The invention provides a membrane-grease 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 grease lubrication is used separately and abrasion is easy to occur and the lubrication effect is poor when the solid membrane is used for lubrication. The method includes performing pre-treatment on work piece surface; processing a solid lubrication membrane on the work piece surface; coating the surface of the solid lubrication membrane with lubrication grease or injecting lubrication grease to the a friction interface of the solid lubrication membrane, so that membrane-grease composite lubrication is realized. According to the invention, the solid lubrication membrane is spaced with grease 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 the combination of solid membrane lubrication suitable for low-speed heavy duty and a grease lubrication method suitable for high speed low duty. Through solid lubrication membrane carrying, lubrication coordination of lubrication and vibration absorption of the lubrication grease is realized. 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 increase energy consumption and cause huge economic losses, but also reduce equipment life and increase safety risks. Lubrication technology is an effective way to reduce friction and wear. In addition, lubrication technology can also reduce noise and reduce health damage to staff. [0003] According to the classification of lubricating medium, common lubrication methods can be divided into liquid lubrication and solid lubrication. As a typical liquid lubrication, the grease is fluid when subjected to high-speed shear at the friction interface, which plays the role of lubrication, cooling, sealing, rust prevention, and elimination of impact and load. However, grease has poor oxidation stability, is easy to evaporate, and the oil film will be destroyed when subjected to high loads. Solid lubrication is actually a technology that us...
