A geared motor is a power transmission mechanism that reduces the number of revolutions of the motor to the required number of revolutions by means of a speed converter of a gear, thereby obtaining a larger torque. The geared motor will inevitably make noise during use. How can we reduce the noise?

Noise reduction measures for geared motors:

1. Properly increase the helix angle of the driving gear. With the increase of the helix angle, the gear overlap will also increase, which will greatly reduce the noise, and it is necessary to choose a suitable helix angle.

2. Improve the lubrication conditions of gears: In order to effectively reduce the noise of the geared motor, appropriate lubrication methods and lubricants should be selected according to the peripheral speed of the gears, and attention should be paid to the combination of lubrication and circulating oil lubrication.

3. Improve gear accuracy: Improve gear accuracy will greatly improve the surface roughness of gears, thereby improving gear motion accuracy and effectively reducing noise.

4. Reasonable selection of tooth surface hardness and gear backlash: when the gear backlash is less than 0.04 mm, the noise is low, so the gear backlash can be appropriately reduced to reduce noise. In addition, when the hardness of the driving gear is 2-3HBC higher than that of the driven gear, the noise of the deceleration motor can be effectively reduced.

5. Special treatment for the tooth surface: Under the design conditions of the gear, the gear can be processed with high-strength, high-damping cast iron or some non-metallic materials, or the tooth surface can be coated with non-metallic materials for processing. Due to the good plasticity and toughness of the material, noise can be effectively reduced by reducing vibration and shock.

6. Increase the width and increase of the tooth surface of the driven gear: the width of the tooth surface will improve the meshing degree of the gear, enhance the relative stability, and improve the noise reduction effect.

7. Reasonable design of the gearbox structure: a reasonable gearbox structure can improve the sealing performance of the gearbox and make it have a good noise reduction effect. If the noise requirements are very high, damping materials such as foam plastic can be placed on the surface of the box to reduce the noise of the geared motor.
