Description

[0001] The utility model relates to a coupling technical field, concretely relates to a high strength coupling. BACKGROUND

[0002] Couplings are also called shaft joints, which are used to firmly connect driving shafts and driven shafts in different mechanisms to rotate together and transmit motion and torque. Sometimes, they are also used to connect shafts with other parts (such as gears, pulleys, etc.).

[0003] The existing couplings are generally connected by setting a bearing between the driving half-coupling and the driven half-coupling. However, the connection and fixation stability between the driving half-coupling and the driven half-coupling is poor. Therefore, we propose a high-strength coupling. SUMMARY

In addition, an auxiliary support is also provided, which can disperse part of the stress during rotation on the auxiliary support. By setting a second bolt, a connecting rod and a support arm, the stress borne by the second bolt can be dispersed to the connecting rod and the support arm in the rotating state, reducing the pressure on the second bolt, improving the connection stability and rigidity of the overall coupling, and reducing the risk of damage to the second bolt.
