Embodiment Construction

[0030] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As mentioned above, the present invention provides a sliding bearing processing technology with good manufacturability, simple operation and low energy consumption.

[0031] See figure 1 , a sliding bearing processing technology, comprising the following steps:

[0032] A, blanking 20: the original blank for blanking is a tubular bar stock 10, along the length shown by the dotted line 15, the original blank is cut off according to the length of the sliding bearing on the sawing machine, and the primary blank 11 of the sliding bearing is obtained. The outer diameter of the original blank is 0.1mm larger than the outer diameter of the sliding bearing final product, and the inner diameter of the original blank is 0.1mm smaller than the inner diameter of the sliding bearing final product;

[0033] B. End face chamfering 21: c...

The processing technology proposed by the present invention improves the efficiency and improves the the quality of the product.

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...
