[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. Standard gears are gears whose parameters meet standard values. Standard gears for different purposes are manufactured according to different standards. Standard gears are often used as measuring gears, reference samples for producing gears, or for correcting measuring instruments. Gear transmission is a mechanical transmission that uses the teeth of two gears to mesh with each other to transmit power and motion. According to the relative position of the gear axes, it is divided into parallel axis cylindrical gear transmission, intersecting axis bevel gear transmission and staggered axis helical gear transmission. It has the characteristics of compact structure, high efficiency and long life.

[0003] When gears are used in conjunction with shafts, the gears will become difficult to disassemble after long-term use, and a jack and a pusher will be used for disassembly. This is because the gears are an integral whole and the disassembly lubrication is insufficient, so tools are required for disassembly. However, the existing gears are not convenient for internal lubrication during disassembly, resulting in difficulty in disassembly and replacement. Therefore, the technical personnel in this field provide a gear that is easy to replace to solve the problems raised in the above background technology. Utility Model Content
