Mineral engineering machinery and long-life bearing block

Abstract

The invention discloses a long-life bearing block, which comprises a bearing block body and a bearing cap arranged on the bearing block body, wherein a bearing hole is formed in each of the bearing block body and the bearing cap; shaft holes are formed in the two sides of the bearing hole, and the diameters of the shaft holes are smaller than that of the bearing hole; sealing grooves are formed at the shaft holes; a cylindrical cavity is formed between the bearing hole and one shaft hole, and the external diameter of the cylindrical cavity is smaller than the aperture of the bearing hole; an oil storage cavity is formed in the bearing block body and the bearing cap, and is positioned between the bearing hole and one shaft hole; scrap accumulation holes communicated with the oil storage cavity are also formed in the lower part of the oil storage cavity; the oil storage cavity and the scrap accumulation holes are used for storing a lubricant, so that a large amount of lubricant can be stored in an oil cavity, tiny metal particles and other substances can be precipitated, and the service life of the bearing block is prolonged. In addition, the invention also discloses mineral engineering machinery comprising the long-life bearing block.

Description

technical field [0001] The invention relates to the field of mechanical transmission and mining engineering machinery, in particular to a long-life bearing seat, and the invention also relates to a mining engineering machine having the above-mentioned long-life bearing seat. The above-mentioned long-life bearing seat is mainly used in mining machinery, but it should be understood that the high-life bearing seat provided by the present invention can also be used in ordinary construction machinery. Background technique [0002] Bearing housing is one of the commonly used mechanical parts in the field of mechanical transmission, and bearing housings are involved in almost all places with bearings. [0003] In the existing bearing seat structure, after a period of use, due to factors such as moisture and grease loss, the grease in the bearing seat will experience problems such as aging, deterioration and drying, which will make the bearing in the bearing seat. Bearing damage ca...

AI Technical Summary

Problems solved by technology

[0004] However, with the growth of time, the deteriorated lubricating grease is stored in the cavity and affects the lubrication effect

After the parts in the bearing seat have been running for a long time, the dropped tiny metal particles and other substances will also increase in the bearing seat. They enter the bearing, which not only affects the performance of the lubricant, destroys the formed oil film, but also directly Cause abrasive wear, leading to early failure of bearing fatigue

The preventive measures that can be taken at present are mainly to disassemble the bearing seat for thorough cleaning, but to remove the bearing means to disassemble the shaft and its transmission parts in the bearing and clean them all, that is, overhaul

The scale of overhaul is huge, especially for equipment under harsh environmental conditions, it is very difficult to thoroughly clean the bearings, shafts and their accessories, and it is even more difficult to ensure the cleanliness of the bearing seat when reassembling
