Bearing circulating grease replacement system

Abstract

The invention discloses a bearing circulating grease replacement system. The bearing circulating grease replacement system comprises a bearing structure and a grease sucking and discharging device; alubricating space for arranging lubricating grease is disposed between an outer ring and an inner ring of the bearing structure, and the bearing structure is provided with a grease injection hole anda grease discharging hole which communicate with the lubricating space; the grease discharging hole is connected with a grease sucking opening of a grease sucking and discharging device; the grease injection hole communicates with a grease supply device; a grease outlet of the grease sucking and discharging device communicates with a grease tank of the grease supply device; and a lubricating grease filtering device and / or a cooling device are / is arranged between the grease outlet of the grease sucking and discharging device and the grease tank in series. The lubricating grease filtering deviceand / or the cooling device are / is arranged, a lubricating grease circulating device can clean away harmful substances, the optimal lubricating state is maintained, the time of the optimal lubricatingstate is prolonged, good lubrication is achieved, and the service life of a bearing is prolonged. The temperature of lubricating grease is lowered through the cooling device, the mobility of the lubricating grease is improved, then the lubricating grease is injected into the bearing again, and the function of recovering the characteristics of the lubricating grease is achieved.

Description

technical field [0001] The invention relates to a bearing circulation grease replacement system capable of filtering and / or cooling grease, belonging to the field of grease lubricated bearings. Background technique [0002] There are two main ways to lubricate bearings, one is liquid oil lubrication, this type of bearing must be installed in the box, and there is oil in the box, this type of lubrication has good effect and high cleanliness, but it is not suitable for All bearings, because some bearings cannot be installed inside the shell, the bearings used in wind power generation equipment, construction machinery, etc. belong to this type of bearings, and this type of bearings need to be lubricated with grease, which has a high viscosity , not easy to flow out, the lubrication space between the inner and outer rings of the bearing is completely closed and not easy to flow out in large quantities. As time goes by, the grease will age, harden, and have poor fluidity, which ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a bearing circulation grease replacement system to solve the problem that in the operation process of the bearing in the prior art, many wear particles and impurities will appear, damage the bearing structure, reduce the service life of the bearing structure and / or the temperature inside the bearing Higher, too high temperature will accelerate the problem of grease deterioration
