Description
Technical Field
The utility model relates to a frock clamp, concretely relates to frock clamp of oil film bearing integration processing.
Background
The oil film bearing belongs to a sliding bearing and is in a full fluid lubrication state under the working condition. The oil film bearing is a bearing that carries an oil film by utilizing the hydrodynamic lubrication principle of fluid, that is, by the relative movement of a shaft and a bearing element, by means of the viscosity of lubricating oil and the hydrodynamic action of oil formed in a wedge-shaped gap in a bearing pair.
The bearing oil film is also called as pressure oil film, and has the functions of balancing load, isolating shaft neck and shaft sleeve, converting intermetallic solid friction into liquid molecular friction, and reducing friction and wear to minimum, so that it can meet the requirements of bearing pressure, impact resistance, change speed, rolling precision, structure size and service life in the maximum range.
When the oil film bearing works, a layer of thin oil film is required to be arranged between the bearing bush and the rotating shaft for lubricating. If the lubrication is poor, direct friction exists between the bearing bush and the rotating shaft, the friction generates high temperature, and although the bearing bush is made of special high-temperature-resistant alloy materials, the high temperature generated by the direct friction is still enough to burn out the bearing bush. The bearing bush may be burnt due to the factors of overlarge load, overhigh temperature, impurities in the lubricating oil or abnormal viscosity and the like. The sliding bearing is damaged after the tile is burned.
The oil film bearing is difficult to process, and the material of the bearing bush is characterized in that: low coefficient of friction, sufficient fatigue strength, good running-in properties and good corrosion resistance. The bearing bush material is soft, the inner cylindrical surface is not suitable for being processed by a grinding method, the bearing bush material can be processed by boring, diamond boring, scraping or grinding methods, and the special boring method is adopted according to the specific shape of the oil film bearing with the complicated inner surface shape.
