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

The invention discloses a rolling bearing cooling and lubricating device for a high-power vertical centrifugal pump, which comprises a main shaft, a rolling bearing, a bearing housing, a bearing cap, a bearing pedestal and an oil stopping sleeve. A cavity is arranged on a part, matched with the main shaft, of the bearing housing; the part of the oil stopping sleeve is positioned in the cavity and is matched with the main shaft and the bearing housing; a spiral oil guiding groove is machined on the part, matched with the bearing housing, of the oil stopping sleeve; an oil guiding hole is reserved on the part, corresponding to the cavity, of the bearing housing; the rolling bearing is cooled and lubricated through the spiral oil guiding groove and the oil guiding hole; and a spiral sealing groove is machined on the part, matched with the main shaft, of the oil stopping sleeve, and ensures that the lubricating oil is not leaked.
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...
