Gear processing: cutting and precision forging have their own advantages and disadvantages

Gear processing: cutting processing and precision forging processes have their own advantages and disadvantages, respectively, as follows for reference.

XNUMX. Advantages and disadvantages of precision forged gears:

1. Advantages:

It can obtain relatively high tooth profile accuracy, tooth phase accuracy, surface finish and so on.

2. Disadvantages:

Due to the fact that the fibrous structure of the parts is cut during the tooth profile processing, such as gear hobbing, gear shaping, gear honing, gear grinding, etc., its stress performance and anti-breaking performance are affected. In the case of overload, there is a hidden danger of tooth root fracture. .

XNUMX. Advantages and disadvantages of cutting gears:

1. Advantages:

During the precision forging process, the metal undergoes plastic deformation under high stress,gearThe structure is dense, the metal fiber is continuous, the fatigue strength and wear resistance are much higher than that of the cutting gear, which is suitable for working under frequent impact and heavy load conditions.

2. Disadvantages:

Because of its low precision, rough surface, high working noise, low working speed, it is easy to produce tooth fatigue damage.

The above are some comparative descriptions of gear cutting and precision forging processes, including but not limited to, the choice of product depends on the actual application requirements of the customer, etc. If you are unclear, you can consult EP free of charge.
