Gear Shaper

A gear shaper is a machine tool for cutting the teeth of an internal gear. The name shaper relates to the fact that the cutter engages the part on the forward stroke and pulls away from the part on the return stroke. To cut external teeth, a different machine called a gear hobbing machine is used.

A gear shaper cutter is a circular pinion-shaped cutter with the necessary rake angles to cut. Both the gear blank and cutter are rotated while set in a vertical plane, such as that the two are like gears in mesh. By using a gear shaper machine, gear shaping becomes a faster process than gear planing because the cutting process is continuous and the cutter does not have to be stepped back.

The gear shaper tool is also gear shaped having the same pitch as the gear to be cut. However the number of cutting teeth may be different from that of the gear to be cut.

At DixiTech CNC we offer Fellows gear shapers. Call us today at 513-360-0091 to find out more information.

Gears are manufactured by casting, stamping, machining, powder metallurgical processes, or by a gear shaper machine. In all cases the quality and cost of the resulting gears are different. The template method is the most common machining operation for the production of gears and is carried out by a gear cutting machine. The template gear cutting process involves the production of a gear tooth profile by a single point gear cutting tool which is reciprocated and made to follow a guided path by a template. The profile of the template, the gear shaper is using, corresponds to the shape of the gear tooth being cut. The template method is used for helical gear cutting and spur gear cutting. Universal milling machines are used for cutting, forming, and finishing of gears and can act as a gear cutter, gear shaper, forming and finishing machines.

Gears

Gears are toothed wheels or cogs are positive type drives which are used to transmit motion between two shafts or a shaft and a component having linear motion, by meshing of two or more gears. They have advantage over other drives such as chains and belts in case of precision machines where a definite velocity ratio is of importance and also in case where the driver and the follower are in close proximity.
