Aluminum bronze can be used to produce bearing related products.
[Standard bearing]: The inner diameter or outer diameter, width (height) and size of the standard bearing conform to the bearing shape specified in GB/T 273.1-2003, GB/T 273.2-1998, GB/T 273.3-1999 or other relevant standards size. Features: high degree of versatility, mostly used in common equipment, room temperature environment applications, large batch, wide range of use, and large number of machinery; due to its large-scale and mass production, there are many production enterprises, low cost and low price. [Non-standard bearing]: It is a non-standard bearing. In layman’s terms, it is a bearing that does not meet the external dimensions specified by the national standard, that is, the external dimensions are different from all bearings specified by the national standard. Features: low degree of versatility, mostly used for special equipment and special occasions, small batches, and the majority of new R&D equipment trial products; but due to non-scale and mass production, there are not many production enterprises, the cost is high, and the price is relatively high. expensive. It is mainly produced according to the requirements or drawings provided by customers.
Sliding friction occurs when the sliding bearing is working; the magnitude of the rolling friction mainly depends on the manufacturing accuracy; and the magnitude of the sliding bearing friction mainly depends on the material of the bearing sliding surface. Sliding bearings generally have self-lubricating working surfaces; sliding bearings are divided into non-metallic sliding bearings and metal sliding bearings according to materials.
Non-metallic sliding bearings are mainly plastic bearings, plastic bearings are generally made of engineering plastics with better performance; more professional manufacturers generally have engineering plastics self-lubricating modification technology, through fibers, special lubricants, glass beads And so on, the engineering plastics are self-lubricated and modified to achieve a certain performance, and then the modified plastics are processed into self-lubricating plastic bearings by injection molding.
At present, the most used metal sliding bearing is the three-layer composite bearing. This kind of bearing is generally based on carbon steel plate. Through sintering technology, a layer of spherical copper powder is first sintered on the steel plate, and then a layer of about 100% is sintered on the copper powder layer. 0.03mm PTFE lubricant; the main function of the middle layer of spherical copper powder is to enhance the bonding strength between the steel plate and PTFE, of course, it also plays a certain role in bearing and lubrication during work.
