How To Improve The Gear Precision Of DC Motor

When the DC motor is in use, if the accuracy of the gear is not accurate, then we need to take corresponding measures. In order to ensure the effect of the use, we must improve its accuracy. So how should we do it?

1. Analysis of hobbing machining accuracy: The accuracy of the shaft tooth is mainly related to the motion accuracy, the stationarity accuracy and the contact accuracy. In the hobbing process, the length of the common normal line and the ring diameter of the ring gear are used to ensure the motion accuracy of the DC motor. The tooth profile error and the base curve deviation are used to ensure the smoothness of the work. The tooth pitch error is controlled to ensure the contact accuracy.

2. Ring spring runout error: The ring gear radial runout means that the probe is in the tooth groove or on the gear teeth within the range of the gear rotation, and the two sides of the tooth height are in contact with each other. The probe is relative to the tooth axis. The maximum amount of change. It is also the eccentricity of the gear ring with respect to the center line of the shaft. This eccentricity is caused by the fact that the two center holes of the DC motor parts do not coincide or the deviation of the center of rotation of the table is too large when the parts are mounted. Or because the top and top holes are not made well, the positioning surface is not well contacted to cause eccentricity.

Therefore, the ring diameter jump should be mainly solved from the above reasons. If the accuracy of the DC motor gear is not accurate, we must solve the problem fundamentally. Of course, when we are dealing with it, the method is different. Therefore, we must first find the correct cause and then analyze an optimal solution so that the problem can be solved. Improve its accuracy.
