Sliding bearing machining process

Abstract

The invention relates to a mechanical manufacturing process, and in particular relates to a process of manufacturing and material processing of sliding bearings. The invention discloses a sliding bearing machining process, comprising the following steps: blanking, end surface chamfering, end surface grinding, punching, chamfering of an oil filling hole, quenching and tempering, centerless grinding, squeezing, and surface grinding. Through the sliding bearing machining process, a sliding bearing is used for lowering frictional resistance of machine running, and is high in machining precision. On the premise of satisfying the machining precision of the sliding bearing, the efficiency and the product quality can be improved by the machining process.

Description

technical field [0001] The invention relates to a mechanical manufacturing process, in particular to a sliding bearing manufacturing and material processing process. Background technique [0002] Bearings that bear loads by sliding motion of shafts and bearings are called sliding bearings. According to the difference in the formation principle of the oil film on the two relative moving surfaces of the sliding bearing. It can be divided into hydrodynamic lubricated bearings (also known as dynamic pressure bearings) and hydrostatic pressure bearings (also known as hydrostatic bearings). The more commonly used is the hydrodynamic lubricated bearing, which brings oil between the two surfaces through the relative movement of the shaft and the bearing, forming a sufficient pressure film to separate the two surfaces, thereby bearing the load. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, which can also great...
