Gear shaving
In this article, we will learn about Gear Shaving Process. In this cold working process, H.S.S. Gear rotates with a cutter. Cutter, rack, or pinion figure. The cutter is very hard and precise grinding is done and the shaving cutter serrations as shown in Fig.
Serrations serve as the cutting tool, with small cavities at the base of each teeth. These cavities are located in the metal to hold and cool the particles.
Gear shaving pattern in shaving cutter and work gear is shown in the picture. Work gear is tucked between two centers. Work gear rotates seamlessly.
The cutter axis is tilted to the gear axis equal to the helix angle of the cutter. The work gear is pressed to touch the shaving cutter. From work gear to burrs, nicks, and other unwanted metals in the form of chips. The shaving cutter rotates at high speed.
The work gear along with the cutter rotates. At the same time, the cutter is reciprocated. Due to the movement of the cutter work gear, the cutter releases burrs, nicks, and unwanted metal from the work gear in the form of chips. This is how the gear shavin finishes are done.
Applications
- This method is used for finishing spur gear and the helical gear.
- This method is generally used for hardened gear.
- This method is used for internal, external gear.
