To connect ZSY gear reducer and motor, it is usually recommended to operate in accordance with the following standard sequence and steps. This not only ensures the normal operation of the equipment, but also effectively extends its service life:
1. Preparation and inspection before installation
Before connecting, you must first confirm that the appearance of the motor and ZSY reducer is intact. Strictly check whether the dimensions of the parts connecting the motor and the reducer match, especially the dimensions and fitting tolerances of the positioning boss of the motor, the groove of the input shaft and the reducer. At the same time, wipe the anti-rust oil on the motor input shaft, positioning boss and reducer connection parts with gasoline or special cleaner to ensure the tightness of the connection and the flexibility of operation.
2. Adjust the reducer and prepare the motor
Unscrew the screws on the dust-proof holes on the outside of the reducer flange, adjust the clamping ring to align the side holes with the dust-proof holes, insert the hexagon socket bolts and tighten them (be careful not to tighten them first). Next, be sure to remove the key on the motor shaft (if there is one) and adjust the motor shaft keyway to a position perpendicular to the tightening bolt on the reducer.
3. Natural connection and preliminary fixation
Connect the motor and reducer naturally. When connecting, it must be ensured that the concentricity of the output shaft of the reducer and the input shaft of the motor is consistent, and the flanges on the outside of the two are kept parallel. Inconsistent concentricity can cause the motor shaft to break or the reducer gear to be severely worn.
To ensure uniform stress, first screw on the two diagonally positioned mounting bolts, but do not tighten them; then screw on the other two diagonally positioned bolts. Tighten the four mounting bolts one by one.
4. Final tightening and inspection
After confirming that the connection is tight and the concentricity is correct, tighten the force bolts. All tightening bolts must use a torque wrench and perform final fixing and inspection in accordance with the fixed torque data indicated in the manufacturer"s instructions.
Core notes:
Hitting is strictly prohibited: During the installation process, it is strictly prohibited to use tools such as hammers to directly hit the reducer or motor shaft to prevent excessive axial or radial force from damaging the internal bearings or gears.
Connection method: ZSY series, as a parallel shaft hard tooth surface reducer, usually uses flange direct connection or foot installation with coupling connection. If couplings are used for connection, it is recommended to give priority to elastic couplings (such as plum blossom couplings) to compensate for slight installation deviations.
Following the above sequence of operations can effectively avoid problems such as abnormal vibration, noise and oil leakage when the equipment is running.
