Planetary Gearboxes

The main transmission structure of the planetary gearbox is: planetary gear, sun gear, ring gear, drive motor and transmission shaft.

The planetary gearbox can be divided into three sections from the appearance: input section, deceleration section and output section.

Input section: The input section refers to the end connected to the motor. Including input shaft hole, input flange

Deceleration section: The deceleration section refers to the core section of the reducer, which looks like a box from the outside, but actually contains many core components, such as planetary gears, sun gears, and ring gears.

Output section: The output pin refers to the end connected to the equipment, including the output shaft and output flange.

Small size, light weight, high bearing capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency and safe performance. It has the characteristics of power splitting and multi-tooth meshing. The transmission efficiency of planetary gearboxes is generally more than 90%, and can reach more than 95%, which is widely used.

The first step.
Before installation, to confirm that the motor and the gearbox are intact and strictly check that the motor and the gearbox connected to the dimensions of the various parts match, here is the motor positioning boss, input shaft and gearbox grooves and other dimensions and matching tolerances.
Step two.
Spin the screws on the dust hole on the outside of the deceleration delan, adjust the PCS system clamping ring so that its side holes are aligned with the dust holes, and insert the inner hexagon tightness. After that, remove the motor shaft key.
Step three.
Connect the motor to the gearbox naturally. When connecting, it is important to ensure that the gearbox output shaft is the same as the motor input shaft and that the outer flan is parallel. As if the heart degree is not consistent, it can cause the motor shaft to break or the gear of the reducer to wear out.

During installation, it is strictly forbidden to hit with a hammer, etc., to prevent axial or radial forces too large damage to bearings or gears. Be sure to tighten the mounting bolts before swirling them tightly. Before installation, wipe the rust-proof oil of the motor input shaft, positioning boss and gearbox connection with gasoline or zinc sodium water. The aim is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.
Before connecting the motor to the gearbox, the motor shaft keyway should be perpendicular to the tight bolt. In order to ensure uniform force, the mounting bolts in any verse position are first screwed, but do not tighten, and then the mounting bolts in the other two verse positions are finally tightened one by one four mounting bolts. Finally, spin the tight force bolt. All tight bolts need to be secured and checked by the torque plate hand according to the indicated fixed torque data.
The correct installation between the gearbox and the mechanical equipment is the same as the correct installation between the gearbox and the drive motor. The key is to ensure that the gearbox output shaft is in the same heart as the drived part of the shaft.
