Details Of Flat Keys

A flat key is a key that relies on two sides as the working surface and transmits torque by squeezing the key and keyway sides. There are three types of flat keys: ordinary flat keys, thin flat keys, and guided flat keys. Ordinary flat keys have good alignment, high positioning accuracy, and are easy to assemble, but they cannot achieve axial fixation of parts on the shaft. They are used for high-speed or shafts that withstand impact and variable loads; Thin flat keys are used in thin-walled structures and areas with low torque transmission; The guided flat key is fixed to the shaft with screws, and is used in situations where the parts on the shaft do not move much along the shaft.
