Planetary reduction drive in the use of the process there will be some noise, the emergence of the noise, how to deal with it?

Planetary reduction drive

The noise of Planetary reduction drive is mainly caused by the friction, vibration and collision of the transmission gears. How to effectively reduce and reduce the noise to make it more in line with the requirements of environmental protection is also a key research topic at home and abroad.Reducing the gear transmission noise of Planetary reduction drive has become an important research topic in the industry. Many scholars at home and abroad regard the change of gear tooth engagement stiffness in gear transmission as the main factor of gear dynamic load, vibration and noise.By modifying the shape, the dynamic load and velocity fluctuation are minimized to reduce the noise.This method has proved to be more effective in practice.But with this method, the process needs to have shape modification equipment, the majority of small factories often can not be implemented.

Planetary reduction drive is a kind of of Planetary reduction drive, what is the transmission structure of planetary gear?Let's take a look.

 

A planetary gear includes a sun wheel, a planetary wheel, and a gear ring, wherein the planetary wheel is supported by a fixed axis of the planetary frame, allowing the planetary wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in constant meshing state.

 

Located in the center of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the planet wheel often engage, two external gear meshing rotation direction is opposite.Just as the sun is at the center of the solar system, the solar wheel is named for its location.Gear ring is the inner gear, it and the planet wheel often meshing, is the inner tooth and the outer gear meshing, the rotation direction between the two is the same.The number of planetary gear depends on the design load of the Planetary reduction drive, usually three or four, the more the number of bear the load is greater.

 

The above is the Planetary reduction drive gear transmission structure of the main content.

Planetary speed of Planetary reduction drive is a kind of speed of Planetary reduction drive, then, the planetary speed of Planetary reduction drive in the process of using the cause of the shaft break what?Let's take a look.

 

1. The wrong type selection causes insufficient output torque of the Planetary reduction drive.

 

Some users in the model selection, mistakenly as long as the selected rated output torque Planetary reduction drive to meet the work requirements can be, in fact, it is not, one is the rated output torque of the motor rated output torque times deceleration ratio, the value obtained in principle should be less than the product sample to provide similar Planetary reduction drive rated output torque.The other is to consider the overload capacity of the drive motor and the maximum operating torque required in practice.

 

2. In the process of acceleration and deceleration, the instantaneous torque borne by the output shaft of the Planetary reduction drive exceeds 2 times of its rated output torque, and such acceleration and deceleration is too frequent, which will eventually make Planetary reduction drive break the shaft.

 

Theoretically, the maximum operating torque required by the user must be less than 2 times the rated output torque of the Planetary reduction drive, especially in some applications must strictly comply with this criterion.This is not only to protect the Planetary reduction drive, but also to prevent the output shaft of Planetary reduction drive from being twisted off.The main reason is that, if there is a problem in equipment installation, the output shaft of the Planetary reduction drive and its load are stuck, the overload capacity of the driving motor will still make it constantly increase the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque 2 times and thus twist the output shaft of the Planetary reduction drive.

Planetary gear reduction drive

The first step is to confirm whether the motor and Planetary reduction drive are in good condition before installation, and strictly check whether the size of each part connected with the motor and Planetary reduction drive is matched. Here are the size and matching tolerance of the positioning boss, input shaft and Planetary reduction drive groove of the motor.

Step 2: unscrew the screw on the outer dustproof hole of of Planetary reduction drive flange, adjust the clamping ring of PCS system to align the side hole with the dustproof hole, insert the inner hexagon to tighten.After that, remove the motor shaft keys.

The third step is to connect the motor with Planetary reduction drive naturally.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the motor must be consistent when connected, and the outer flange of the two must be parallel.If the concentricity is not consistent, the motor shaft will be broken or of Planetary reduction drive gear wear.

In addition, in the installation, do not use hammer and other blows, prevent the axial force or radial force too much damage to the bearing or gear.Be sure to tighten the mounting bolt before tightening the force bolt.Before installation, wipe away the anti-rust oil of motor input shaft, positioning boss and connecting part of of Planetary reduction drive with gasoline or zinc-sodium water.Its purpose is to ensure tight connection and flexibility of operation, and prevent unnecessary wear and tear.

Planetary reduction drivePlanetary reduction drive

Before the motor and Planetary reduction drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, first screw the installation bolts at any diagonal position, but do not screw tight, then screw the installation bolts at the other two diagonal positions, and finally screw the four installation bolts one by one.Finally, tighten the force bolt.All tightening bolts shall be fixed and checked by the torque plate hand according to the indicated torque data.

Correct installation between of Planetary reduction drive and mechanical equipment is the same as correct installation between of Planetary reduction drive and drive motor.The key is to ensure that the output shaft of Planetary reduction drive and the drive part of the shaft concentricity.
