[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. For this reason, gears are relatively widely used. However, existing gears are generally arranged in an integrated structure. Therefore, after damage, they need to be recycled as a whole, which leads to replacement costs. At the same time, in order to prevent wear during long-term use, manual lubrication needs to be added regularly, which makes it relatively cumbersome. Summary of the Invention

[0007] In the above-mentioned split gear assembly, the lubrication unit is composed of several lubrication blocks with lubrication cavities. The inner and outer walls of the lubrication blocks are slidably fitted with the assembly ring portion and the external tooth portion respectively. The end face of the lubrication block is provided with a convex ring portion that protrudes axially outward and facilitates the filling of lubricating oil into the lubrication cavity. The convex ring portion is provided with a sealing cover connected to it.

[0008] In the above-mentioned split gear assembly, a flow hole is provided on the wall surface of the outer tooth portion, which is axially recessed inward and extends into the lubrication cavity. The outer tooth portion is provided with a connecting rod at the flow hole, which is slidably matched with the flow hole, connected to the lubrication block, and improves the sealing of the connection. The connecting rod is hollow.

[0009] Compared with the prior art, the split gear assembly can be split and disassembled, and can also be lubricated. BRIEF DESCRIPTION OF THE DRAWINGS
