Development status and trend of precision forging technology for spur gears

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.

Development status and trend of precision forging technology for spur gears

Gear is a widely used mechanical transmission part, which has the characteristics of compact structure, large power transmission, high efficiency, long service life, good reliability and accurate transmission ratio.

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?

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?

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 aspects does the chain wheel manufacturer guarantee the product quality?

Chain wheel is a mechanical accessory that many manufacturers often need. The quality of chain wheel will affect the service life and operating cost of various machines. What aspects do chain wheel manufacturers guarantee product quality?
