Main differences between big gear and sprocket

Main differences between big gear and sprocket

Chain wheel is one of the big gears. It is not the direct cogging of wheels, but the mutual cogging of wheels and chains. Therefore, the processing requirements are much lower. Next, let's briefly share the difference between gears and sprockets.

Forging is the use of forging machinery to exert pressure on metal blanks

Forging is the use of forging machinery to exert pressure on metal blanks

Forging is a processing method that uses forging machinery to exert pressure on metal blank to make it produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components.

What are the requirements for the materials used for forged parts?

What are the requirements for the materials used for forged parts?

The materials for forgings are mainly carbon steel and alloy steel of various compositions, followed by aluminum, magnesium, copper, titanium, etc. and their alloys. The original state of materials includes bar stock, ingot, metal powder and liquid metal. The ratio of cross sectional area of metal before deformation to that after deformation is called forging ratio. The correct selection of forging ratio, reasonable heating temperature and holding time, reasonable initial and final forging temperature, reasonable deformation amount and deformation speed have a great relationship to improve product quality and reduce cost.

How to shrink the outer circle of ring forging to the inner circle as much as possible through heat treatment?

How to shrink the outer circle of ring forging to the inner circle as much as possible through heat treatment?

In modern pressure processing, for the production of large round forgings, roll rolling mill (reamer) can be used for roll forging forming, which has the advantages of accurate size, high production efficiency, good quality of forgings, etc. In the absence of production conditions for roll forging, it can be formed by expanding holes on a free forging hammer or hydraulic press with a horse stand.

What factors will cause noise during gear transmission

What factors will cause noise during gear transmission

Gears are easy to wear parts in various machines. In the process of use, you can often hear the rattling noise. This is due to the continuous impact and vibration on the gear teeth when the gear is engaged with Guo Chenzhong.

Production Process of Forged Flange Parts

Production Process of Forged Flange Parts

The flange production process is mainly divided into forging, casting, cutting and rolling. The flange sealing forms are: raised face (RF), concave face (FM), convex face (M), tenon face (T), groove face (G) and full face (FF).

Residual heat of heavy forgings

Residual heat of heavy forgings

Let's talk about the heat treatment of heavy forgings directly after forging by using the heat of forgings themselves. That is, the process of reheating forgings before heat treatment after forging is omitted from the heat treatment of forgings. Generally, there are several methods of heat treatment by waste heat.
