Planetary reduction travel in the application of the process you will see some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction travel is mainly due to the friction, vibration and collision of the transmission gears. How to effectively reduce and decrease the noise to create it more in line with the requirements of environmental coverage is also an integral research topic in the home and overseas.Reducing the gear transmission sound of Planetary reduction travel has become a significant research theme in the industry. Many scholars at home and abroad regard the change of equipment tooth engagement stiffness in gear transmission as the main factor of gear dynamic load, vibration and sound.By modifying the form, the dynamic load and velocity fluctuation are minimized to lessen the noise.This method has proved to be more effective used.But with this method, the process needs to have shape modification equipment, nearly all small factories often can not be implemented.
Planetary reduction drive is definitely a sort of of Planetary reduction travel, 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 band, wherein the planetary wheel is supported by a set axis of the planetary body, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the apparatus ring are in continuous meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the earth wheel typically engage, two external equipment meshing rotation direction is normally opposite.Just as sunlight is at the center of the solar system, the solar wheel is known as because of its location.Gear band is the inner gear, it and the earth wheel often meshing, is the interior tooth and the outer gear meshing, the rotation direction between your two may be the same.The number of planetary gear depends upon the design load of the Planetary reduction travel, usually 3 or 4, the more the amount of bear the strain is greater.
The above may be the Planetary reduction drive equipment transmission structure of the primary content.
Planetary speed of Planetary reduction drive is normally a kind 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 productivity torque of the Planetary decrease drive.
Some users in the model selection, mistakenly as long as the selected rated outcome torque Planetary reduction travel to meet up the work requirements could be, in fact, it isn’t, one may be the rated output torque of the electric motor rated output torque situations deceleration ratio, the value obtained in principle should be less than the merchandise sample to provide similar Planetary reduction drive rated productivity torque.The other is to consider the overload capacity of the drive motor and the utmost operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the productivity shaft of the Planetary lowering drive exceeds two times of its ranked output torque, and this sort of acceleration and deceleration is certainly too frequent, which will eventually make Planetary lowering drive break the shaft.
Theoretically, the maximum operating torque required by the user 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 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 load are stuck, the overload capacity of the generating motor will still make it constantly raise the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and so twist the output shaft of the Planetary reduction travel.
