Why are some metal gears replaced by plastic gears in geared motors? This is usually due to five reasons: noise and vibration reduction, weight reduction, cost reduction, increased lubrication and corrosion resistance, and ease of design. Using Fengtech geared motors as an example, we’ll explain the importance of plastic gears. Reduce Noise The engineering plastics used inside the motor have inherent damping and shock absorption capabilities, absorbing the impacts and vibrations generated during motor start-up, stopping, and load changes. This makes the gear transmission process smoother and quieter. For example, in our motor production, to typically keep noise levels below 50 dB, replacing metal gears with plastic gears is a […]
