Problems solved by technology
At present, the rolling bearings used in high-power vertical centrifugal pumps are mainly cooled and lubricated by engine oil, usually using an external circulation system for cooling and lubrication; this requires the addition of external circulation systems for high-power vertical centrifugal pumps, and corresponding fixing devices. This makes the high-power vertical centrifugal pump bulky and expensive; and once the circulation pipeline fails, the rolling bearing will be burned out

A cooling and lubricating device for a rolling bearing of a high-power vertical centrifugal pump, comprising a main shaft, a rolling bearing, a bearing sleeve, a bearing cover, a bearing seat, and an oil retaining sleeve. The cavity is matched with the main shaft and the bearing sleeve. A spiral oil guide groove is machined at the matching part of the oil retaining sleeve and the bearing sleeve. An oil guide hole is opened in the corresponding cavity of the bearing sleeve. Cooling and lubrication; a spiral sealing groove is machined in the matching part of the oil retaining sleeve and the main shaft, and the lubricating oil is not leaked through the spiral sealing groove.
Description
technical field [0001] The invention relates to a cooling and lubricating device for rolling bearings, in particular to a cooling and lubricating device for rolling bearings in vertical pumps, especially a cooling and lubricating device for rolling bearings in high-power vertical centrifugal pumps. Background technique [0002] In the application field of vertical pumps, rolling bearings are the key components supporting the motor and pump rotating device; due to the high-speed rotation driven by the motor, the bearings are prone to friction and heat; therefore, the cooling and lubrication of rolling bearings is a problem that needs to be fully considered in the design process of vertical pumps . At present, the rolling bearings used in high-power vertical centrifugal pumps are mainly cooled and lubricated by engine oil, usually using an external circulation system for cooling and lubrication; this requires the addition of external circulation systems for high-power vertical...
