Planetary Gearheads compact small size thanks to the planetary transmission principle, the input shaft output shaft in the same center line, which makes the model achieve the smallest possible size. Planetary Gearheads smooth operation and low noise cycloidal gear engagement number, overlap coefficient and has a balancing mechanism, the vibration and noise restricted to a minimum. On the planetary gear factory in Hubei http://www.yousheng1688.com feel vibration reasons: 1, planetary reducer and motor coupling parts is not vertical, resonance, dismantle the motor to be re-installed. 2, with planetary reducer output shaft coupled to bend or change the line to be detected output shaft concentricity. 3, equipment and planetary gearhead shaft center height inconsistent installation, shall adjust the mounting surface of the planetary gear unit, ensure that the equipment shaft and planetary gearhead two mounting dimensions are equal.
