In the reducer, the planetary gear reducer has the characteristics of light weight, small size, wide transmission ratio, high efficiency, stable operation, low noise and strong adaptability, so it is widely used in metallurgy, mining, lifting and transportation, power, energy, building materials, light industry, transportation and other industrial sectors. However, an inline spur gear gearbox wholesale must be installed before use. Improper installation may lead to the fracture of the output shaft of the reducer and bring unnecessary economic losses to the enterprise.

In order to let you better understand the installation steps, reduce unnecessary economic losses, take you to understand the installation steps and precautions of inline spur gear gearbox wholesale.

First, installation

1. The first step: Before installation, confirm whether the motor and reducer are in good condition, and strictly check whether the dimensions of the components connected with the motor and reducer match. The following are the dimensions and fitting tolerances of the motor positioning boss, input shaft and reducer groove.

2. Step 2:

Loosen the screws on the dust hole outside the reducer flange, adjust the grip ring of the PCS system so that its side hole is aligned with the dust hole, insert the hex and tighten. After that, remove the motor shaft key.

Step 3:

Connect the motor to the reducer naturally. When connected, the concentricity of the output shaft of the reducer and the input shaft of the motor must be consistent, and the outer flange of the reducer and the motor must be parallel. Inconsistent concentricity can cause motor shaft breakage or reducer gear wear. In addition, during the installation process, it is strictly prohibited to knock with a hammer. To prevent excessive axial or radial force damage to bearings or gears. Be sure to tighten the mounting bolt before tightening the force bolt. Before installation, use gasoline or zinc sodium water to wipe the anti-rust oil at the motor input shaft, positioning boss and reducer connection. The purpose is to ensure the tightness of the connection and the flexibility of the operation to prevent unnecessary wear.

Before connecting the motor to the reducer, the keyway of the motor shaft should be perpendicular to the tightening bolt. In order to ensure uniform force, first screw any diagonal position of the mounting bolts, but do not tighten, then screw the other two diagonal position of the mounting bolts * * * and then tighten the four mounting bolts one by one. * * *, tighten the force bolt. All tightening bolts shall be fixed and checked with a torque wrench according to the marked fixed torque data. The correct installation of the reducer and the mechanical equipment is similar to the correct installation of the reducer and the drive motor. The key is to ensure that the concentricity of the output shaft of the reducer is consistent with that of the driven part of the shaft.

1) Connection between reducer and working machine

The reducer is set directly on the main shaft of the working machine. When the reducer is in operation, the anti-torque acting on the reducer housing is balanced by the anti-torque bracket installed on the reducer housing or other methods. The machine is directly matched, and the other end is connected with the fixed bracket

2) Install torque support

The reaction torque bracket shall be installed on the side of the reducer facing the machine to reduce the bending moment attached to the shaft of the machine. The axle sleeve and fixed support at the connection end of the anti-torque bracket are elastomer such as rubber to prevent deflection and absorb torque fluctuations. 3) Installation relationship between reducer and working machine

In order to avoid the deviation of the spindle of the working machine and the additional force on the bearing of the reducer, the distance between the reducer and the working machine should be as small as possible without affecting the normal operation, and the value should be 5-10mm.
