Grease lubrication bearing system

Abstract

The invention discloses a grease lubrication bearing system. The grease lubrication bearing system comprises a bearing structure and a lubricating grease circular drive device; according to the bearing structure, a lubricating space used for containing lubricating oil is arranged between the outer ring and the inner ring of the bearing structure, an oil injection hole and an oil draining hole communicating with the lubricating space are formed in the bearing structure, the oil draining hole is connected with a grease absorbing opening of the lubricating grease circular drive device, a grease outlet of the lubricating grease circular drive device is connected with the oil injection hole of the bearing, and a lubricating grease filter device and/or a cooling device are/is arranged between the lubricating grease circular drive device and the oil injection hole in a series manner. The lubricating grease filter device and/or a cooling device are/is arranged, harmful substance can be cleanedthrough the lubricating grease circular device, the optimal lubricating state can be maintained, the time of the optimal lubricating state is prolonged, the good lubricating is obtained, the servicelife of the bearing is prolonged, through the cooling device, the lubricating grease temperature is reduced, the lubricating grease liquidity is improved, the lubricating grease is injected into the bearing again, and the lubricating grease characteristic effect can be restored.

Description

technical field [0001] The invention relates to a grease lubricating bearing system capable of filtering and / or cooling grease, and belongs to the field of grease lubricating 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 cannot me...

AI Technical Summary

Problems solved by technology

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