Gear Shaper

A gear shaper is a machine tool for cutting the teeth of internal or external gears. 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, just like the clapper box on a planer shaper.

The cutting tool is also gear shaped having the same pitch as the gear to be cut. However number of cutting teeth must be less than that of the gear to be cut for internal gears. For external gears the number of teeth on the cutter is limited only by the size of the shaping machine. For larger gears the blank is usually gashed to the rough shape to make shaping easier.

The principal motions involved in rotary gear shaper cutting are of the following :

  1. Cutting Motion: The downward linear motion of the cutter spindle together with the cutter .
  2. Return Stroke: The upward linear travel of the spindle and cutter to withdraw the latter to its starting position.
  3. Indexing Motion: Slow speed continuous rotation of the cutter spindle and work spindle to provide circular feed, the two speeds being regulated through the change gears such that against each rotation of the cutter the gear blank revolves through n/N revolution, where "n" is the number of teeth of the cutter, and "N" is the number of teeth to be cut on the blank.
  4. Completion of Cutting Operation: The indexing and reciprocating motions continue until the required number of teeth to the required depth are cut all along the periphery of the gear blank.

Famous quotes containing the words shaper and/or gear:

    Man acts as though he were the shaper and master of language, while in fact language remains the master of man.
    Martin Heidegger (1889–1976)

    For women ... bras, panties, bathing suits, and other stereotypical gear are visual reminders of a commercial, idealized feminine image that our real and diverse female bodies can’t possibly fit. Without these visual references, each individual woman’s body demands to be accepted on its own terms. We stop being comparatives. We begin to be unique.
    Gloria Steinem (b. 1934)
