Description
Technical Field
[0001] The utility model relates to a sector convex tooth coupling, belonging to the technical field of coupling transmission. Background Art
[0002] A coupling is a mechanical component used to connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. Couplings can be divided into two categories: rigid couplings and flexible couplings. For some machines, at the end of the work, the driving shaft and the driven shaft need to be separated, and only flexible couplings can be used. Since most of the flexible couplings on the market at present have the same shape for each convex tooth, they can only be applied to the occasions where there is no requirement for the position alignment of the assembly of the driving shaft and the driven shaft. For the occasions where the driving shaft and the driven shaft need to be rotated to a specific position before connection, the current flexible couplings still cannot meet the requirements. Therefore, it is an urgent problem to design a coupling with requirements for position alignment during assembly, more stable transmission, and convenient separation. Summary of the Utility Model
