3 major features of small modulus gear hobs (for reference)

Gear hobs process straight and helical teeth according to the principle of helical gear meshingCylindrical gearOf a kind of tool.Among them, the three major characteristics of the small module gear hob are explained as follows, for reference.

1. Usually made into an integral single-head hob

Commonly used materials are cemented carbide and high-speed steel.

2. Full-cut hobbing is usually used

Especially when processing correction cycloid gears and other non-involute gears.

3. The chip pocket is opened into a straight groove

Because the small module gear hob has a small helix angle and straight groove manufacturing is simple, the straight groove hob cutter teeth are gradually cut into the tooth blank, so the cutting is stable, and the influence of the error caused by the asymmetry of the cutting angle is small.

The above is the description of the 3 major characteristics of the small module gear hob shared today. If you have any related questions orGear processingIf you need, you can consult EP for free.
