Abstract

The invention discloses a thin-wall long-barrel-shaped bearing containing oil and a production method of the thin-wall long-barrel-shaped bearing containing the oil. The thin-wall long-barrel-shaped bearing containing the oil is characterized in that the bearing is produced from the following components by weight: 28.32-32.43% of CS-100, 49.94-60.16% of SA100, 11.52-17.63% of AG1L3, and zinc stearate, molybdenum disulfide, graphite and dispersion enhancer of which the percentages in the total weight of the three kinds of powder are respectively 0.66%, 0.26%, 0.75% and 0.1%. The thin-wall long-barrel-shaped bearing is prepared by mixing the components, molding, pressing and sintering. The product disclosed by the invention has enough strength, small deformation, small shrinkage, high strength, and good consistence of produced product height and inner hole.

Description

technical field [0001] The invention relates to a bearing, in particular to a thin-walled long barrel-shaped oil-impregnated bearing and a production method thereof. Background technique [0002] With the development of science and technology, the requirements for copper-based oil-impregnated bearings are getting higher and higher, mainly in high operating speed; the online speed used in textile machinery in the early days was only 3-5m / s, but now used in textile machinery The speed of copper-based oil-impregnated bearings must be above 10m / s. Secondly, it is used in household appliances, especially in audio equipment. Oil-impregnated bearings are required to have a small friction coefficient, stable operation, vibration reduction and low noise, and long service life. General requirements Above 5000h. In order to meet people's high-performance and high-quality requirements for copper-based oil-impregnated bearings, people have done a lot of research on material selection. A...
