The use and maintenance of the precision planetary reducer is an important part of ensuring the normal operation of mechanical equipment.Therefore, when installing the planetary reducer, please strictly follow the installation and use related matters below, and carefully assemble and use it.
1. Before installation, be sure to confirm whether the appearance of the motor and the reducer are intact, and check whether the size of the part connecting the motor and the reducer matches, such as the positioning boss of the motor, the input shaft and the concave of the reducer Slot and so on.
2. Unscrew the screws outside the flange of the reducer, adjust the PCS system tightening ring to align with the dust-proof opening, and insert the inner hexagon.
3. Connect the motor and the 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 the same, and the outer flanges of the two are parallel.If the center is inconsistent, it will cause the motor shaft to break or the gear of the reducer to wear.
In addition, during installation, it is strictly forbidden to hit with a hammer, etc., to prevent excessive axial or radial force from damaging the bearings or gears.Be sure to tighten the mounting bolts before tightening the tightening bolts.Before installation, wipe off the anti-rust oil on the motor input shaft, positioning boss and the connection part of the reducer with gasoline or zinc-sodium water.Its 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, the keyway of the motor shaft should be perpendicular to the tightening bolt.To ensure uniform force, first screw on the mounting bolts at any diagonal position, but do not tighten, then screw on the other two diagonal mounting bolts, and finally tighten the four mounting bolts one by one.Finally, tighten the tightening bolts.All tightening bolts need to be fixed and inspected with a torque wrench according to the marked fixed torque data.
Precision planetary gearboxes are used in many places, but people just use them without knowing its data. If they don’t know enough about it, they can’t exert its full power. Precision planetary gearboxes are subject to people’s attention due to structural reasons. Blitz.
From the data analyzed by experts, it can be seen that the minimum single-stage deceleration is 3, and the maximum generally does not exceed 10. The common reduction ratio is: 3.4.5.6.8.10, the number of reducer stages generally does not exceed 3, but some large reduction ratios are custom-made The machine has 4 decelerations.Compared with other reducers, precision planetary reducers have high rigidity, high precision (single-stage can be within 1 minute), high transmission efficiency (single-stage 97%-98%), high torque/volume ratio, and lifetime maintenance-free Features.Because of these characteristics, most precision planetary reducers are installed on stepper motors and servo motors to reduce speed, increase torque, and match inertia.
The rated input speed of the precision planetary reducer can reach up to 18000rpm (depending on the size of the reducer itself, the larger the reducer, the smaller the rated input speed) and above, the output torque of the industrial precision planetary reducer generally does not exceed 2000Nm, and the special ultra-large torque precision planetary The reducer can achieve more than 10000Nm.The working temperature is generally around -25℃ to 100℃, and the working temperature can be changed by changing the grease.
The backlash level (arc minutes) of the precision planetary reducer is very important because of the servo motor. The price of different backlash levels is quite different. The precision planetary reducer can be connected with multiple gearboxes and the maximum reduction ratio can reach 100000.
The applicable conditions are as follows:
The peripheral speed of the gear drive of the reducer does not exceed 10 m/s.
The input shaft speed is not higher than 1500 rpm.
The working environment temperature of reducer is -40℃-+45℃.
The reducer can be used for forward and reverse rotation.
Precision planetary reducer: The main transmission structure is: planetary gear, sun gear, and outer ring gear.
