Sliding bearing machining technique

Abstract

The invention relates to a mechanical manufacture technique, in particular to the manufacture and material processing technique of a sliding bearing. The invention discloses a sliding bearing machining technique comprising the following steps of blanking, end face chamfering, end face grinding, punching, oil filler hole chambering, thermal refining, centerless grinding, extruding, and surface grinding. According to the sliding bearing machining technique, the sliding bearing is used for reducing the frictional resistance in a machine operation and is high in machining accuracy. In the premise that the machining accuracy is met, efficiency is improved and production quality is improved.

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...
