Description
Bevel gears manufacturing starts production from a forging, bar stock, or any other formed product such as a casting, depending on the strength requirements of the finished bevel gear. A forged blank is used when a superior strength to weight ratio, as well as better impact and fatigue resistance is necessary.
The forging, casting or bar stock is machined into a blank. Threads and splines maybe added on to the blank if the design so requires, and other machining processes such as turning, milling, drilling and tapping etc. are carried out prior to teeth cutting.

Next, the bevel gear teeth are cut into the blank. There are two main manufacturing methods to cut bevel gear teeth, and the tooth length and depth forms vary depending on the process adopted. The system uses the single indexing or face milling procedure, where every gap is milled separately, and the gear then rotated by the width of that tooth space. Bevel gears produced via this method have a tapered tooth depth and tooth thickness, and the curvature along the face width is that of a circular arc.
This results in a coniflex gear, where the ends of the teeth curve slightly inward, allowing for greater tolerance of minor errors in shaft alignment as compared to straight cut teeth.
