A common flat key, semi-circular key, hook head wedge key function:
1. The common flat key is the most light because it has a simple structure, convenient dis-assembly and assembly, good neutrality, suitable for high speed, load-bearing and impact occasions.
2. The semi-circular key is shaped like a semicircle and can be swung in the key-way to adapt to the shape of the bottom surface of the hub key-way. It is often used for the connection of the tapered shaft end and the connection workload is not large.
