An introduction to the hard finishing of gears through the decades, including a gear quality, historical processes, and pre-finishing processes.
Gear shaving is the process of finishing by running the gear at high velocity in mesh with a gear shaving tool. The tool is a type of rack or pinion with hardened serrations which serve as the cutting edge. Roll finishing involves using two hardened rolling dies placed accurately with respect to the profile of the gear being finished.
This paper reports on reduction of noise and vibrations of cylindrical and conical gears through simultaneous reduction in their microgeometry errors, functional parameters, and surface roughness by finishing them …
3. Gear Shaving Process of finishing of gear tooth by running it at very high rpm in mesh with a gear shaving tool. A gear shaving tool is of a type of rack or pinion having hardened teeth provided with serrations. These serrations serve as cutting edges which do a scrapping operation on the mating faces of gear to be finished. Both gears in …
Vibratory finishing, centrifugal barrel finishing and turbo-abrasive machining are the three top techniques for finishing gears, improving performance and extending …
Gear honing is a widely utilized finishing process used in the automobile, aviation, and other industries to improve the surface texture of gears and reduce transmission noise.
The finishing process is used to get a high quality shape of the gear and to get low surface roughness. To get low cutting forces in the finishing step, the material stock after the roughing ...
Gear shaving is a free-cutting gear finishing operation which removes small amounts of metal from the working surfaces of the gear teeth. Its purpose is to correct errors in index, helical angle, tooth profile and eccentricity. The process can also improve tooth surface finish and eliminate, by crowned tooth forms, the danger of tooth end load …
Gear shaving is a surface finishing process that involves removing small metal parts from a gear. It is suitable for making a gear smoother. Aside from that, it is applicable in correcting gear teeth in terms of spacing, angle, profile, concentricity, etc.

This gear manufacturing article will guide you multiple ways and the right choice depends on the type of gear and your application.
What operations are used after gear manufacturing? In this guide, we have 5 different types of gear finishing processes to understand.
The residual stress level of the gear tooth with the barrel finishing process was obviously lower than that with the grinding process. Subsequently, the contact-fatigue test was performed on a closed power-flow test bench (shown in Figure 2) under a constant torque of 1.115 kN·m with a rotation speed of up to 1200 r/min. The gears were ...
Gear finishing processes are necessary to produce accurate, smooth gear teeth after initial formation. The main gear finishing processes are gear shaving, burnishing, grinding, lapping, and honing. Gear shaving involves running a gear against a cutter to scrape off irregularities. Gear burnishing plastically moves excess material …
