With the development and demand of the industry, the requirements for the noise control of the stain wave gears are getting higher and higher. There are many factors that affect the noise of the stain wave gears, such as the tooth profile design of the internal and external gears, the gear machining accuracy, the assembly accuracy, the use, maintenance and installation of the reducer.

1.Tooth profile design of the internal and external meshing gears of the stain wave gears

The noise of the stain wave gears is mainly caused by the friction, vibration and collision of the transmission gear. In the design, the meshing speed and meshing effect are reduced by optimizing parameters such as the modulus, tooth height, modulus, pressure angle, and center distance of the gears.

Design methods that reduce or avoid gear mesh effects can reduce the noise of stain wave gears.

2.Stain Wave Gears machining accuracy

The hardened tooth surfaces obtained by carburizing, nitriding and carbonitriding processes deform the gears, increase the noise of gear transmission, and shorten the service life of the gears.

In order to reduce the noise of the stain wave gears, the tooth surface needs to be repaired; the tooth grinding and modification methods are used to reduce the influence of the gear inlet and outlet.

3.Assembly accuracy of stain wave gears

(1)Stain wave gears assembly is not concentric, resulting in an unbalanced drive shaft, half loose and half tight meshing of the internal gears, and noise.

(2) The internal gear assembly of the stain wave gears has a small clearance and slightly louder noise.

(3)If there is too much oil and grease in the stain wave gears, the noise will be slightly louder.

4.Use and maintenance of stain wave gears

(1) Different installations of stain wave gears and equipment will cause noise.

(2) Stain wave gears bearing; internal noise;

(3) The internal of stain wave gear wears out, and the gear clearance is too large, resulting in noise.

According to the actual situation of the site, the cause of the noise of the stain wave gear is analyzed in detail.

Compared with the spur gear reducer, the helical cylindrical stain wave gear has a higher degree of coincidence. The tooth profiles of the two wheels start to contact from a point, and the contact line changes from short to long, then shortens until point contact, and then disengages. Like the spur gear transmission, it suddenly contacts and suddenly disengages along the entire tooth width, but gradually enters and gradually disengages, so that the impact is small, the noise is small, and the transmission is stable.
