Description

Technical Field

[0001] The utility model relates to a bearing cross bag with lubrication. Background Art

[0002] The cross-axis universal coupling is the most commonly used coupling. Its structural characteristics can make two axes that are not on the same axis or have a large axis angle or large axial movement rotate continuously at the same angular speed, and reliably transmit torque and motion. It can be widely used in mechanical shaft systems in lifting, engineering transportation, mining, petroleum, shipping, coal, rubber, papermaking machinery and other heavy machinery industries to transmit torque; the reason why the cross-axis universal coupling can rotate in all directions is that its two ends are connected by the cross bag of the bearing.

[0003] In the daily use of the cross-axis universal coupling, the bearing cross package needs to be lubricated to avoid serious wear of the connection due to insufficient lubrication. Currently, the lubrication of the bearing cross package is mostly done manually, and the bearing cross package and the external connection need to be disassembled for lubrication, which is cumbersome. At the same time, since the bearing cross package rotates frequently, the bearing cross package needs to be maintained and lubricated frequently, which is time-consuming and labor-intensive.
