Features:
1: The flat key is a key that relies on two sides as the working surface, and relies on the extrusion of the key and the side of the keyway to transmit the torque;
2: The flat key is divided into three types according to the function and use: ordinary type flat key, thin type flat key and guide type flat key;
3: Ordinary flat keys have good neutrality, high positioning accuracy, and are easy to disassemble and assemble, but cannot achieve axial fixation of parts on the shaft, and are used for shafts with high speed or impact and variable loads;
4: The thin flat key is used for thin-walled structures and places where the transmission torque is small. The guide type flat key is used to fix the key on the shaft with screws, and is used for occasions where the parts on the shaft do not move much along the shaft;
