Gear drawing required for machine design

A gear drawing is a type of important technical reference required when designing machines. When a machine designer requires a gear when designing a new machine, there are two possibilities: designing the new gear itself, and utilizing a standard gear which has already been designed. In either case, the gear drawing is indispensible.

Although this applies to machine elements in general, gear drawings must contain accurate descriptions of principle gear specifications such as number of teeth, pitch such as modules, pitch circle diameter (PCD), helix angle of helical teeth, value of tooth profile shifting, precision grade such as DIN and AGMA, geometrical tolerance, and roughness of surface.

Also, because the strength to allow the torque required to transmit power through the gears is required, it is also necessary to accurately list the hardness of the gear, which is quantified in terms of gear material, tempering or lack thereof and tempering method, HRC and HB achieved after tempering, etc.

Gear drawings are generally provided in 2D CAD, 3D CAD, and print media formats, but on the KHK website it is also possible to output a drawing with the modifications applied to stock gears such as bore, keyway, and set screw hole part modifications.
