Gearhead Noise
When operating under the same conditions, the sound produced will hardly change at all. However, the sound may seem louder due to the following:
- The load conditions change. The backlash noise of a gearhead varies depending on the load conditions. For example, when there is no load, the gears bounce when rotating, and the gears rotate while continuously colliding with each other, causing vibration and noise. This noise can be suppressed by adding a friction load.
Check the load conditions that are causing the workpiece to resonate and make loud noises, as well as the method of fixing the workpiece to the mounting surface. - When assembling a motor and gearhead with a damaged motor shaft or when the internal gears become fatigued due to overload, scratches on the teeth may occur, causing abnormal noise when the motor rotates. To avoid scratches on the teeth, use the pilot parts as a guide when assembling, and gently rotate the gearhead left and right while assembling, taking care not to hit the gearhead side plate or gears too hard.
