Problems solved by technology

As the DN value (bearing diameter) increases, the high-pressure zone formed inside the bearing will make it difficult for lubricating oil to enter. Simply increasing the flow of lubricating oil will increase power loss and generate more heat. Traditional oil injection lubrication is difficult Meet the lubrication requirements of high DN value bearings

Abstract

The bearing oil supply sleeve and the bearing oil supply device comprise a sleeve body, the sleeve body is provided with an oil collecting part, a flow distribution part and a bearing installation part, and the oil collecting part is arranged on the outer wall of the sleeve body and used for collecting oil at the oil collecting part; the bearing mounting part is arranged on the outer wall of the sleeve and is used for mounting an inner ring of a bearing; the flow distribution part is arranged in the pipe wall of the sleeve or on the inner wall of the sleeve and used for distributing oil collected by the oil collection part to the bearing installation part. According to the bearing oil supply device, the oil liquid at the position of the oil collecting part is collected and transferred to the flow distribution part, the collected oil liquid is distributed to the position of the bearing mounting part through the flow distribution part, the oil liquid is transferred to the inner ring of the bearing, and oil supply to the inner ring of the bearing is achieved. The lubricating and cooling effects of the inner ring of the bearing can be improved by utilizing oil supply of the inner ring, the lubricating oil consumption and the power loss are reduced, the overall lubricating and cooling effects of the bearing can be greatly improved, and safe and reliable operation of the bearing in a high-DN value use scene is met.

Description

technical field [0001] The disclosure belongs to the technical field of lubrication and cooling, and in particular relates to a bearing oil supply sleeve and a bearing oil supply device. Background technique [0002] At present, the bearings of high-speed generators adopt lubrication and cooling methods such as oil injection lubrication, which have low lubrication and oil supply efficiency, and the lubrication and cooling of the inner ring of the bearing are poor; or the bearings are soaked in lubricating oil, and the oil is violently stirred to cause a lot of heat. After the lubricating oil enters the bearing, most of it is used to provide cooling and take away the heat generated by the bearing. Only a small part of the lubricating oil forms an oil film in the contact area between the ball and the track to lubricate. As the DN value (bearing diameter) increases, the high-pressure zone formed inside the bearing will make it difficult for lubricating oil to enter. Simply incr...
