Small module gear shaping principle, movement and common product structure (for reference and understanding)

The related descriptions of the machining principle, movement and common product structure of small module gears are as follows, for reference and understanding.

Gear shaping principle:

Gear shaping is made up of the gear shaping tool and the workpiecegearThere is a gapless meshing movement between them, and the gear shaper tool reciprocates and rotates around its own axis, cutting out the tooth profile of the workpiece during the generating movement.

For the involute tooth profile, each gear shaping cutter can process gears with the same modulus but different numbers of teeth.For processing modified cycloid gears, even if the modulus is the same, the number of teeth is different, the same gear shaping tool cannot be used.

Gear shaping can process some gears that cannot be machined such as gear hobbing and milling, such as double gears,Internal gearand so on.

Gear shaping movement:

Gear shaping movement includes: reciprocating circular movement, radial feed movement, indexing movement and knife movement.
