Bearing block, oil cavity cleaning and lubricating system and method for bearing block, and mineral engineering machinery

Abstract

The invention discloses a bearing block, which comprises a bearing sleeve and a bearing cap, wherein a flange is arranged at one end of the bearing sleeve, and a through shaft hole is formed in the other end of the bearing sleeve; a threaded hole is also formed in the flange, is connected with an oil inlet hole passage, and is communicated with a bearing hole through the oil inlet hole passage; an oil outlet threaded hole and an oil outlet hole passage are also formed in the flange, and the oil outlet hole passage is communicated with a transition section of the bearing sleeve to form a loop, so that an oil cavity of the bearing block is cleaned; the oil inlet hole passage and the oil outlet hole passage can be flexibly formed, so that the universality of the bearing block is improved, and the application range of the bearing block is widened. In addition, the invention discloses a bearing-block-based bearing block cleaning and lubricating system and a bearing-block-based bearing block cleaning and lubricating method. The system has the advantages of simple structure, safety, reliability, good cleaning and lubricating effects, capability of automatically cleaning and lubricating the bearing block and high applicability. Moreover, the invention provides mineral engineering machinery based on the bearing block and the bearing block oil cavity cleaning and lubricating system.

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
