1. Installation Steps for Worm Gear Reducers
2. . Select the installation location: make sure that the installation location is dry, clean, and well ventilated, and take into account the convenience of maintenance and safety factors.
3. . Mounting foundation: place the reducer on the mounting foundation, check for leveling using a level, and make necessary adjustments.
4. . Axis alignment: Make sure that the input shaft of the reducer and the output shaft of the drive equipment maintain coaxiality to avoid wear and tear caused by axis misalignment.
5. . Connecting the motor: connect the gearhead to the motor and make sure the connection is tight and firm.
6. . Adjustment of position: adjust the position of the reducer to make it harmonize with other equipment.
7. . Test run: after the installation is completed, carry out a test run to check whether the reducer is running normally, whether there is abnormal noise and excessive high temperature.
