My planetary gearbox is noisy and abnormal, is it a malfunction?

The operating principle of a gearbox is to rely on the internal gears to mesh with each other to achieve power transmission. Any mechanical components that are in contact with each other will inevitably produce certain sounds during operation, whether it is a sprocket, rack and pinion, rail or ball screw. The manufacturers are in their efforts to control the sounds and prevent bad effect on the operator.

Generally, users often judge the sound level of the gearbox subjectively by ears, and everyone feels and describes the sound differently. In order to have a common standard with global users to define the sound level, we use decibel (dB) as a unit of measurement, and state the volume of sound produced by the gearbox under certain conditions in the catalogue. The gearboxes will be tested and confirmed in accordance with the standards recorded in the catalogue before delivery, so that the products purchased by users can fully comply with the specification.

So how do we measure the sound level of our products before leaving the factory? The gearboxes are tested under the conditions of environmental noise 30 dBA at a input speed of 3000 rpm without load, by a accurate noise meter measured at a distance of one meter, to ensure the consistency of shipment quality.

Feel free to contact Sesame Motor if you have any questions about the noise of your gearbox, we will confirm the quality of the gearbox by the inspection process consistent with the standard of leaving our factory.
