Planetary reduction drive in the application of the process there will be some noise, the emergence of the noise, how to deal with it?
The noise of Planetary reduction travel is mainly caused by the friction, vibration and collision of the transmission gears. How to efficiently reduce and reduce the noise to create it more based on the requirements of environmental security is also a key research topic at home and abroad.Reducing the apparatus transmission sound of Planetary reduction drive has become an important research subject matter in the market. Many scholars in the home and abroad regard the change of equipment tooth engagement stiffness in equipment transmission as the main factor of gear dynamic load, vibration and noises.By modifying the form, the dynamic load and velocity fluctuation are minimized to lessen the noise.This method has became more effective in practice.But with this technique, the process needs to have shape modification equipment, the majority of small factories often can not be implemented.
Planetary reduction drive is normally a kind of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun wheel, a planetary wheel, and a gear band, wherein the planetary steering wheel is supported by a fixed axis of the planetary framework, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, sunlight wheel and the gear ring are in regular meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the earth wheel frequently engage, two external gear meshing rotation direction can be opposite.Just as the sun is at the guts of the solar program, the solar wheel is known as because of its location.Gear ring is the inner gear, it and the earth wheel often meshing, may be the interior tooth and the outer gear meshing, the rotation direction between your two is the same.The quantity of planetary gear depends upon the design load of the Planetary reduction travel, usually 3 or 4, the more the quantity of bear the load is greater.
The above is the Planetary reduction drive gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is a sort of speed of Planetary reduction drive, then, the planetary speed of Planetary reduction drive along the way of using the cause of the shaft break what?Let’s have a look.
1. The wrong type selection causes insufficient result torque of the Planetary decrease drive.
Some users in the model selection, mistakenly provided that the selected rated result torque Planetary reduction travel to meet up the work requirements can be, in fact, it is not, one may be the rated end result torque of the motor rated output torque instances deceleration ratio, the worthiness obtained in principle should be less than the product sample to provide similar Planetary reduction travel rated result torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary reduction drive exceeds 2 times of its ranked output torque, and this kind of acceleration and deceleration is usually too frequent, which will eventually make Planetary decrease travel break the shaft.
Theoretically, the utmost operating torque required by an individual must be significantly less than two times the rated output torque of the Planetary reduction drive, especially in some applications must strictly comply with this criterion.This is not and then protect the Planetary reduction drive, but also to avoid 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 own load are stuck, the overload capacity of the driving motor will still make it constantly boost the output force, which might cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque 2 times and so twist the output shaft of the Planetary reduction drive.

Here are the size and complementing tolerance of the positioning boss, input shaft and Planetary lowering travel groove of the motor.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary reduction drive flange, adapt the clamping ring of PCS program to align the side hole with the dustproof hole, insert the inner hexagon to tighten.After that, take away the motor shaft keys.
The third step is to connect the engine with Planetary reduction drive by natural means.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the electric motor must be regular when connected, and the outer flange of the two should be parallel.If the concentricity isn’t consistent, the motor shaft will be broken or of Planetary decrease drive gear wear.
Furthermore, in the installation, usually do not use hammer and different blows, avoid the axial force or radial force an excessive amount of damage to the bearing or equipment.Make sure to tighten the mounting bolt ahead of tightening the drive bolt.Before installation, wipe away the anti-corrosion oil of motor input shaft, positioning boss and connecting portion of of Planetary reduction drive with gasoline or zinc-sodium water.Its purpose is to ensure tight connection and overall flexibility of operation, preventing unnecessary wear and tear.
Before the motor and Planetary reduction drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, 1st screw the assembly bolts at any kind of diagonal position, but usually do not screw tight, then screw the unit installation bolts at the different two diagonal positions, and lastly screw the four installation bolts one at a time.Finally, tighten the force bolt.All tightening bolts shall be fixed and examined by the torque plate hand according to the indicated torque data.
Right installation between of Planetary reduction drive and mechanical products is equivalent to correct installation between of Planetary reduction drive and drive motor.The key is to make certain that the output shaft of Planetary reduction travel and the drive section of the shaft concentricity.
