Flat Key
PT24041202
A flat key is a key that relies on two sides as working surfaces and relies on the extrusion of the key and keyway sides to transmit torque. Flat keys are divided into three types: ordinary flat keys, thin flat keys, and guided flat keys. Ordinary flat keys have good centering, high positioning accuracy, and are easy to fold and assemble, but cannot achieve axial fixation of parts on the shaft. They are used for shafts that are at high speed or bear impact or variable loads; thin flat keys are used for thin-walled structures and transmission Where the torque is small; the guide-type flat key uses screws to fix the key on the shaft, and is used in situations where the parts on the shaft move little along the shaft.
