Abstract

The invention belongs to the technical field of oil-retaining bearings, and discloses a powder metallurgy oil-retaining bearing manufacturing process. The manufacturing process of the powder metallurgy oil bearing comprises the following steps that S1, aluminum-based powder, iron powder and graphite powder are weighed and mixed, and a mixture is prepared; s2, pressing the mixture into a pressed blank; s3, the pressed blank is sintered, and a sintered blank is obtained; s4, chamfering, sharp edge removing and secondary blank pressing are conducted on the sintered blank, and a semi-finished product is obtained; S5, engine oil is heated, and the semi-finished product is put into the heated engine oil to be soaked; s6, during soaking, the temperatures of the upper layer, the middle layer and the lower layer of the engine oil are detected through a temperature detector; s7, detected data are collected, and when the temperature difference of the upper layer, the middle layer and the lower layer exceeds a preset value, a stirrer is started to stir engine oil, it can be guaranteed that the oil temperature is uniform, and the quality of used raw materials can be controlled.

Description

technical field [0001] The invention relates to the technical field of oil-impregnated bearings, in particular to a powder metallurgy oil-impregnated bearing manufacturing process. Background technique [0002] Oil-impregnated bearings, that is, porous bearings, use metal powder as the main raw material. Oil-impregnated bearings are sintered bodies made by powder metallurgy. They are inherently porous and have the ability to freely adjust the pores during the manufacturing process. Technical advantages such as quantity, size, shape and distribution, low cost, vibration absorption, low noise, no need to add lubricating oil during a long working time, etc., especially suitable for working environments that are not easy to lubricate or do not allow oil to be dirty . Porosity is an important parameter for oil bearings. Oil-impregnated bearings working at high speed and light load require high oil content and high porosity; oil-impregnated bearings operating at low speed and he...
