7 Ways To Reduce Gear Motor Noise

Gearmotors are used for a wide variety of applications. However, the noise generated during operation remains a major concern. While helical gear motors are great in this regard, is it possible to achieve noise reduction in all gearmotors? The answer is yes, provided you follow these 7 tips.

Tips To Reduce Gear Motor Noise

Employs High Precision Gears

High precision in this context means low pitch error, profile error and lead error. These will go a long way towards improving noise reduction. Also, grinding or finishing the gear teeth properly will also contribute to reducing excess noise.

Reduce Backlash

Backlash occurs when there is a gap between two teeth as the direction of motion reverses. Finding the right balance is key to reducing noise. Too big or small a gap will be detrimental to noise reduction.

Increase Contact Ratio

Increasing the contact ratio between the teeth of two gears within a gearmotor will produce less impact during contact. This will thereby reduce noise production. Increasing the tooth depth and decreasing the pressure angle are excellent ways to achieve this.

Use Gears With Smaller Teeth

If possible, look to reduce the gear tooth size and increase the number of teeth. This will also aid in reducing unwanted noise.

Increase The Face Width Of The Gears

Increasing the face width of the gears can make the gears more rigid and thereby reduce noise production when they mesh. This will improve the operation characteristics of a gearmotor.

Lubricate Properly

Reducing excessive friction between the moving parts will also aid in noise reduction. High-viscosity lubrication is the best choice in this regard. However, the lubricant must be selected according to the gear motor.

Make Sure The Gears Have No Dents

A chipped or dented gear tooth will lead to abnormal noise generation when meshed with another gear. To avoid this, the gears in the gear motor should be inspected for dents.
