Flat key and half-round key connection

1. Flat key and half-round key connection

Flat key----The side of the key is the working surface, and the torque is transmitted by the extrusion of the key and the keyway

Flat keys are divided into three types-ordinary flat keys\guide flat keys\sliding keys

Thin flat key-used for thin-walled parts

There are three kinds of ordinary flat keys, which are used for static connection, and the feather key is used for dynamic connection. There are two types of round head and square head. When the axial movement distance is large, the sliding key is used (Guide: The advantages of stainless steel tapping machine and Technical parameters of stainless steel tapping machine)

Semi-circular keys-cut or punched from round steel and ground

Semi-circle key: working on the side, the advantage is that the craft is good, and it can automatically adapt to the inclination requirements

The disadvantage is that the keyway on the shaft is deep;

2. Advantages and disadvantages of flat key and half-round key connection

----Simple\compact\reliable\easy to assemble and disassemble\low cost

----The keyway weakens the shaft strength, the stress is concentrated, the centering is difficult, and the axial force transmission and fixation cannot be realized.
