Planetary reduction drive in the utilization of the process you will see 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 exactly to successfully reduce and decrease the noise to create it more in line with the requirements of environmental security is also an integral research topic in the home and overseas.Reducing the gear transmission noise of Planetary reduction travel has become a significant research subject in the market. Many scholars in the home and abroad respect the change of equipment tooth engagement stiffness in gear transmission as the primary factor of gear powerful load, vibration and sound.By modifying the form, the dynamic load and velocity fluctuation are minimized to reduce the noise.This method has became more effective in practice.But with this method, the process needs to have shape modification equipment, nearly all small factories often can’t be implemented.
Planetary reduction drive is definitely a sort of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun wheel, a planetary steering wheel, and a gear ring, wherein the planetary wheel is supported by a set axis of the planetary body, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, the sun wheel and the gear ring are in regular meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the earth wheel often engage, two external gear meshing rotation direction is normally opposite.Just as the sun is at the guts of the solar system, the solar wheel is known as for its location.Gear band is the internal gear, it and the earth wheel often meshing, may be the interior tooth and the outer gear meshing, the rotation direction between the two may be the same.The quantity of planetary gear is determined by the design load of the Planetary reduction travel, usually three or four, the more the quantity of bear the load is greater.
The above may be the Planetary reduction travel gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is a sort of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive along the way of using the reason for the shaft break what?Let’s have a look.
1. The wrong type assortment causes insufficient end result torque of the Planetary decrease drive.
Some users in the version selection, mistakenly so long as the selected rated end result torque Planetary reduction travel to meet up the work requirements could be, in fact, it is not, one may be the rated end result torque of the motor rated output torque times deceleration ratio, the worthiness obtained in principle should be less than the merchandise sample to supply similar Planetary reduction travel rated outcome torque.The other is to consider the overload capacity of the drive electric motor and the utmost operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the end result shaft of the Planetary lowering drive exceeds 2 times of its rated output torque, and this sort of acceleration and deceleration is usually too frequent, that will eventually make Planetary reduction travel break the shaft.
Theoretically, the utmost operating torque required simply by an individual must be significantly less than two times the rated output torque of the Planetary reduction drive, especially in a few applications must strictly comply with this criterion.This is simply 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 travel and its own 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 travel to exceed its rated output torque 2 times and thus twist the output shaft of the Planetary reduction drive.

Here are the size and complementing tolerance of the positioning boss, source shaft and Planetary lowering drive groove of the motor.
Step two 2: unscrew the screw on the external dustproof hole of of Planetary decrease drive flange, modify the clamping ring of PCS program to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.After that, remove the motor shaft keys.
The 3rd step is to hook up the electric motor with Planetary reduction drive the natural way.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the engine must be regular when connected, and the external 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 different blows, prevent the axial force or radial force an excessive amount of harm to the bearing or equipment.Be sure to tighten the mounting bolt prior to tightening the force bolt.Before installation, wipe aside 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 flexibility of operation, and stop unnecessary wear and tear.
Before the motor and Planetary decrease drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, first screw the assembly bolts at any diagonal position, but usually do not screw restricted, then screw the installation bolts at the different two diagonal positions, and finally screw the four assembly bolts one by one.Finally, tighten the force bolt.All tightening bolts will be fixed and checked by the torque plate hand according to the indicated torque data.
Correct installation between of Planetary reduction drive and mechanical products is equivalent to right installation between of Planetary reduction travel and drive engine.The main element is to make certain that the output shaft of Planetary reduction drive and the drive section of the shaft concentricity.
