The old method of gear cutting is mounting a gear blank in a shaper and using a tool shaped in the profile of the tooth to be cut. This method also works for cutting internal splines. Another is a pinion-shaped cutter that is used in a gear shaper machine. It is basically when a cutter that looks similar to a gear cuts a gear blank.
Bench scraper, Scraper, Bench knife. To shape or cut dough, and remove dough from a worksurface. Most dough scrapers consist of handle wide enough to be held in one or two hands, and an equally wide, flat, steel face. Edible tableware. Varies. Tableware, such as plates, glasses, utensils and cutlery, that is edible.
A gear center is the center of the pitch circle. Gear range. The gear range is difference between the highest and lowest gear ratios and may be expressed as a percentage (e.g., 500%) or as a ratio (e.g., 5:1). Heel Heel and toe. The heel of a tooth on a bevel gear or pinion is the portion of the tooth surface near its outer end.
Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets using a hobbing machine, a specialized milling machine.The teeth or splines of the gear are progressively cut into the material (such as a flat, cylindrical piece of metal or thermoset plastic) by a series of cuts made by a cutting tool called a hob.
Gear. Two intermeshing spur gears rotating at different velocity due to differing gear ratio. A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called cogs ), which mesh with another (compatible) toothed part to transmit rotational power.
The process of gear shaping uses a toothed disk cutter which reciprocates in axial rotations. The workpiece (or blank gear) rotates on a second shaft (spindle). The workpiece is aligned with the cutter and it gradually feeds into the cutter while rotating. If a two-step process is used, all tooth spaces are partially cut before finishing.
Gear shaper. A gear shaper is a machine tool for cutting the teeth of internal or external gears, it is a specialised application of the more general shaper machine. 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 ...
Edwin R. Fellows (May 29, 1865 – May 21, 1945) was an American inventor and entrepreneur from Torrington, Connecticut who designed and built a new type of gear shaper in 1896 and, with the mentoring of James Hartness, left the Jones & Lamson Machine Company to co-found the Fellows Gear Shaper Company in Springfield, Vermont, which became one of the leading firms in the gear-cutting segment ...
