Bearing block, system for cleaning oil chamber of bearing block, mineral engineering machine and engineering machine

Abstract

The invention discloses a bearing block, which comprises a bearing sleeve and a bearing cap; the bearing sleeve is of a structural form with a flange; a shaft through hole is formed in the other end of the bearing sleeve; the flange is also provided with a structure that a threaded hole is connected with an oil inlet way and communicates with a bearing hole; the flange is also provided with a structure that an oil outlet threaded hole, an oil outlet way and a transition section of the bearing sleeve communicate to form a loop, therefore cleaning on an oil chamber of the bearing block is realized; moreover, the oil inlet way and the oil outlet way can be arranged in a comparatively flexible manner, so that universality of the bearing block is increased and an applicable range of the bearing block is broadened. In addition, the invention also discloses a bearing block-based system and a bearing block-based method for cleaning and lubricating the bearing block; the system and the method are capable of realizing automatic operation of cleaning and lubricating the bearing block, and are high in applicability. Moreover, the invention also provides a mineral engineering machine and an engineering machine which apply the bearing block and the system for cleaning and lubricating the oil chamber of the bearing block.

Description

technical field [0001] The invention relates to the field of engineering machinery and mechanical transmission, in particular to a bearing seat and its oil chamber cleaning and lubricating system and method, and mining engineering machinery. The above-mentioned bearing seat and its oil cavity cleaning and lubricating system and method are mainly used in mining machinery, but it should be understood that the bearing seat and its oil cavity cleaning and lubricating system and method provided by the present invention can also be used in ordinary engineering machinery. Background technique [0002] Bearing housings are one of the commonly used mechanical parts in the field of mechanical transmission, and bearing housings are involved almost everywhere 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 age, deteriorate, and dry out, so that the bearing in the b...

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, and it is very difficult to thoroughly clean the bearings, shafts and their accessories for equipment in harsh environmental conditions, and it is even more difficult to ensure the cleanliness of the bearing housing when reassembling
