Steps for Forging Bevel Gears: A Comprehensive Guide

[vincentpt99]

the question given is this

" Gears can be made of forging especially bevel gears. Through literature survey describe the sequence of manufacturing steps involved in the production of gears."

what i thought is that the gear should be manufactured by extrusion, and then cut it into pieces. but the question had said that gear is manufacture by forging. after i search the internet, no website tell me how to manufacture gears.

can someone help me to solve this question, please...

There is plenty of information out there, you just have to hunt for it. Machinery's Handbook has an entire chapter on gears and splines.

Small gears can be manufactured by extrusion, but that is not the case for larger gears, especially those that require tight tolerances and high precision. A lot of gears can be made from forgings, but will have many secondary machining steps after to finish the part.

I would highly recommend that you start with the American Gearm Manufacturing Association's website (AGMA): http://www.agma.org

I would suggest looking into the following terminology:
- Hobbing
- Grinding (in regards to gear grinding)
- Shaping

I wrote this assuming that you are referring only to metallic gears, not polymer based.

I can provide some insight into the steps involved in forging bevel gears. First, it is important to note that forging is a manufacturing process where metal is heated and shaped by applying pressure. This is different from extrusion, where metal is pushed through a die to create a specific shape.

In the case of forging bevel gears, the first step would be to select the appropriate material for the gear. This could be a variety of metals such as steel, aluminum, or bronze, depending on the specific application.

Next, the selected material would go through a heating process to make it easier to shape. This is known as the preheating stage and is necessary to reduce the force required during the forging process.

Once the material is heated, it is placed into a die or mold that is specially designed to create the shape of a bevel gear. The material is then subjected to high pressure, either through mechanical or hydraulic means, to shape it into the desired form.

After the initial forging process, the gear may go through additional shaping or trimming to achieve the final desired shape. This could include processes such as machining, grinding, or heat treating.

Finally, the bevel gear would go through a finishing process, which could involve polishing, deburring, or coating to improve its durability and functionality.

Overall, the steps for forging bevel gears involve selecting the appropriate material, preheating, shaping through high pressure, additional shaping and trimming, and finishing. It is a complex and precise process that requires skilled labor and specialized equipment. I hope this helps provide a better understanding of the manufacturing steps involved in forging bevel gears.
