Why does noise occur in DC geared motors? What are the common solutions

DC gear motor after a long time, there may be some noise, resulting in this noise for a number of reasons, the common is the internal parts damage, if not dealt with in a timely manner, it is easy to lead to shorten the life of the motor, so what are the common solutions to this situation?

1. The installation of parts is not standardized, not standardized, resulting in resonance of DC gear motor parts, generating noise, should improve the installation process, increase the tooling, to ensure that the installation accuracy meets the requirements.

2. There are parts loose inside the DC gear motor, resulting in inappropriate positioning, non-normal position engagement, vibration and noise, should ensure that the parts are connected and stable.

3. Prevent the body and support and connection parts from resonating and generating noise. One or several gears in the 24V DC gear motor often resonate within a certain speed range. In addition to design reasons, it is directly related to finding out the resonance position without air test during installation and taking corresponding vibration damping or blocking measures. Some of the transmission noise and vibration requirements of the reducer is low, should be selected with high toughness, high damping of the base material to reduce the occurrence of noise and vibration.

4, transmission parts damage during installation, improper operation can damage the transmission parts, resulting in inaccurate or unstable system movement; oil film vibration caused by damage to high-speed moving parts; cause imbalance of artificial moving parts; generate vibration and noise. Pay attention to and avoid these causes as much as possible during the installation process. Damaged parts that cannot be repaired should be replaced to ensure that the noise level of the system is stable.

The above is the solution to the noise of DC gear motor, motor manufacturers in these areas to put more effort, good product quality to establish industry reputation.
