Document Type and Number:
WIPO Patent Application WO/2019/062977
Kind Code:
A1
Abstract:
Disclosed is a grease-lubricated bearing system, comprising a bearing structure and a lubricating grease circulation driving device, wherein a lubrication space used for placing lubricating oil is provided between an outer ring (1) and an inner ring (2) of the bearing structure, the bearing structure is provided with an oil injection hole (4) and an oil discharge hole (5) conducting with the lubrication space, the oil discharge hole is connected to a grease suction opening (15) of the lubricating grease circulation driving device, a grease outlet (10) of the lubricating grease circulation driving device is connected to the oil injection hole of the bearing structure, and at least one of a lubricating grease filtering device (20), a cooling device (23) and an oil product detection device (27) are serially provided between the lubricating grease circulation driving device and the oil injection hole. The lubricating grease circulation driving device can remove harmful substances, thereby maintaining the optimal lubrication state, extending the duration of the optimal lubrication state, obtaining good lubrication, and prolonging the service life of the bearing. The lubricating grease temperature is reduced by means of the cooling device, such that after the fluidity of the lubricating grease is improved, the lubricating grease is re-added into the bearing, thereby achieving the function of restoring the property of the lubricating grease.
