Planetary reduction travel in the use of the process you will have some noise, the emergence of the noise, how to deal with it?
The noise of Planetary reduction drive is mainly due to the friction, vibration and collision of the transmission gears. How exactly to successfully reduce and decrease the noise to make it more in line with the requirements of environmental proper protection is also an integral research topic at home and abroad.Reducing the gear transmission sound of Planetary reduction drive has become an essential research theme in the market. Many scholars at home and abroad regard the change of equipment tooth engagement stiffness in gear transmission as the primary factor of gear dynamic load, vibration and noises.By modifying the shape, the powerful load and velocity fluctuation are minimized to lessen the noise.This technique has proved to be more effective used.But with this technique, the process needs to have shape modification equipment, nearly all small factories often can’t be implemented.
Planetary reduction drive can be a sort of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear carries a sun wheel, a planetary steering wheel, and a gear ring, wherein the planetary steering wheel is supported by a fixed axis of the planetary framework, allowing the planetary steering wheel to rotate on the assisting axis.The planetary wheel, sunlight 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, the sun wheel and the planet wheel often engage, two external gear meshing rotation direction can be opposite.Just as sunlight is at the center of the solar system, the solar wheel is named because of its location.Gear ring is the interior gear, it and the planet wheel often meshing, may be the interior tooth and the outer gear meshing, the rotation direction between the two is the same.The quantity of planetary gear is determined by the look load of the Planetary reduction travel, usually 3 or 4, the more the amount of bear the load is greater.
The above may be the Planetary reduction drive equipment transmission structure of the primary content.
Planetary speed of Planetary reduction drive is certainly a sort of speed of Planetary reduction drive, in that case, 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 assortment causes insufficient productivity torque of the Planetary lowering drive.
Some users in the style selection, mistakenly as long as the selected rated productivity torque Planetary reduction travel to meet up the work requirements can be, in fact, it isn’t, one may be the rated outcome torque of the engine rated output torque circumstances deceleration ratio, the value obtained in principle ought to be less than the merchandise sample to provide similar Planetary reduction travel rated end result torque.The other is to consider the overload capacity of the drive engine and the maximum operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the outcome shaft of the Planetary reduction drive exceeds 2 times of its rated output torque, and this sort of acceleration and deceleration is definitely too frequent, that may eventually make Planetary decrease travel break the shaft.
Theoretically, the utmost operating torque required simply by the user must be less than two times the rated output torque of the Planetary reduction drive, especially in a few applications must strictly adhere to 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, when 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 travelling 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 so twist the output shaft of the Planetary reduction travel.
