Mineral engineering machinery, disassembly-free oil cavity cleanable bearing block and cleaning method

Abstract

The invention discloses a disassembly-free oil cavity cleanable bearing block, which comprises a bearing block body and a bearing cap arranged on the bearing block body, wherein an oil storage cavity is formed in the bearing block body and the bearing cap; a threaded hole communicated with the lateral surface of the bearing block body is formed below the oil storage cavity; a rotary joint of an adjustable oil outlet device is arranged at the threaded hole, so that a function of cleaning an oil cavity of the bearing block without disassembly is realized. The bearing block with the structure has the advantages that the bearing block is easy to use and machine, low in cost and long in service, the service life of a bearing is prolonged, the working environment of the bearing is improved, and the like. In addition, the invention also discloses an oil cavity cleaning method based on the disassembly-free oil cavity cleanable bearing block, which is easy to operate and high in efficiency. Moreover, the invention discloses mineral engineering machinery comprising the disassembly-free oil cavity cleanable bearing block. The mineral engineering machinery has the advantages of simplicity in maintenance and long service life, and the major overhauling cycle of the mineral engineering machinery can be prolonged.

Description

technical field [0001] The invention relates to the field of engineering machinery and mechanical transmission, in particular to a mining engineering machinery, a bearing seat which can be cleaned without disassembly and an oil chamber, and a cleaning method. The above-mentioned bearing seat with a cleanable oil chamber without disassembly is mainly used in mining machinery, but it should be understood that the bearing seat with a cleanable oil chamber without disassembly 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 bearing se...

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
