　　We know the function of worm gear reducer from the literal meaning. If we make a lot of noise while it is working, it will affect us psychologically. Of course, we all hope to have a worm gear reducer with a lower sound. Today, our Ever-Power worm gear reducer manufacturer tells us what are the factors that affect the noise of the worm gear reducer?

(XNUMX) The influence of worm gear reducer gear processing error on noise.
1. Requirements for low-noise gear structure design.The effect of gear structure design on noise is very important. The ideal design is to maximize the bending strength of the gear teeth, choose a larger displacement coefficient and appropriate helix angle to increase the meshing coefficient, so as to achieve the purpose of reducing noise .
2. The influence of gear manufacturing precision of reducer on noise.For the standard series gear reduction stepper motor, the manufacturing precision of the reducer gear determines its noise value.The main function of the gear of the gear reduction motor is to transmit speed and torque. Therefore, its gear manufacturing accuracy is required, and its working stability level is the main.

(XNUMX) The influence of working stability and accuracy on noise.
The working stability and accuracy of the gear of the reducer is required to limit the change of the instantaneous speed ratio of the gear. The error is the rotation angle error that occurs multiple times per revolution of the gear. It is a high-frequency impact sound.For a gear, the factors that affect the smoothness of the work are its base pitch error and its involute tooth profile error.

(XNUMX) The influence of the contact accuracy of the gears of the deceleration stepping motor on the noise.
The comprehensive index for evaluating gear contact accuracy is contact spots. Gears that are not in good contact will have loud noises.The reasons for the unsatisfactory gear contact are: tooth orientation error affects the contact in the tooth length direction, and base pitch deviation and tooth profile error affect the contact in the tooth height direction.

(XNUMX) The influence of the motion accuracy of the reducer gear on noise.
The movement accuracy of the reducer gear refers to the accuracy of the transmission movement, that is, the large error value of the angle of rotation of the gear can not exceed a certain limit.Because the gear movement accuracy is a large periodic error (one revolution of the gear), and the cumulative error of Zhou Jie caused by the radial runout of the gear ring during one revolution of the gear will produce low-frequency noise, but when the cumulative error of the cycle increases, it will cause The gear meshing impact and the angular velocity change, at this time the noise increases significantly and makes a "rumble" sound.

The above is the impact of four points on the noise field of the reducer summarized by the Ever-Power worm gear reducer manufacturer.
