In the power system of the metal chip press, although the function of the motor is relatively important, it cannot provide stable and suitable pressure for the equipment without the reducer. The reducer can stably transmit the power output by the motor to the hydraulic pump. Below, we will introduce the installation steps and precautions of the metal chip press reducer.
Installation steps for the gearbox:
1. Before installation, confirm whether the motor and reducer are intact, and strictly check the size matching of the connecting components between the motor and reducer. This is the size and tolerance of the motor positioning protrusion, input shaft, and reducer groove;
2. Tighten the screws on the outer dust hole of the reducer flange, adjust the snap ring to align the side hole with the dust hole, insert the inner hexagon and tighten it, then remove the motor shaft key;
3. Connect the motor and reducer naturally. When connecting, it is necessary to ensure that the concentricity of the reducer output shaft and the motor input shaft is the same, and that the outer flanges of the two output shafts are parallel. If the concentricity is not consistent, the motor shaft will break or the reducer gear will wear out.
Precautions for gear reducer installation:
Hammering is strictly prohibited during the installation process to prevent excessive axial or radial force from damaging the bearings or gears. Before tightening the forced bolts, be sure to tighten the installation bolts. Before installation, use gasoline or zinc sodium water to wipe off the rust proof oil on the motor input shaft, positioning protrusions, and reducer connection parts. The purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear.
Before connecting the motor to the reducer, please make the keyway of the motor shaft perpendicular to the fastening bolt. To ensure even force, please first tighten the installation bolt in any diagonal position, but do not tighten it too tightly. Then, tighten the installation bolt in the other two diagonal positions, and finally tighten the four installation bolts one by one. Finally, tighten the fastening bolts. All fastening bolts should be fixed and inspected using a torque wrench according to the specified tightening torque data.
