Planetary reduction travel in the utilization of the process you will see some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction drive is mainly due to the friction, vibration and collision of the transmission gears. How to properly reduce and reduce the noise to create it more in line with the requirements of environmental security is also a key research topic in the home and abroad.Reducing the apparatus transmission sound of Planetary reduction travel has become a significant research theme in the market. Many scholars at home and abroad regard the change of equipment tooth engagement stiffness in equipment transmission as the key factor of gear dynamic load, vibration and noise.By modifying the form, the powerful load and velocity fluctuation are minimized to reduce the noise.This technique 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 definitely a kind of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sun wheel, a planetary wheel, and a gear band, wherein the planetary wheel is supported by a fixed axis of the planetary frame, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, sunlight wheel and the apparatus ring are in continuous meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, the sun wheel and the earth wheel quite often engage, two external gear meshing rotation direction is definitely opposite.Just as the sun is at the center of the solar program, the solar wheel is known as for its location.Gear band is the inner gear, it and the earth wheel often meshing, is the internal tooth and the external gear meshing, the rotation direction between the two is the same.The number of planetary gear will depend on the look load of the Planetary reduction drive, usually 3 or 4, the more the quantity of bear the load is greater.
The above may be the Planetary reduction drive gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is normally 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 outcome torque of the Planetary lowering drive.
Some users in the model selection, mistakenly so long as the selected rated output torque Planetary reduction travel to meet up the work requirements could be, in fact, it isn’t, one may be the rated end result torque of the motor rated output torque instances deceleration ratio, the value obtained in principle ought to be less than the product sample to supply similar Planetary reduction travel rated outcome torque.The other is to consider the overload capacity of the drive engine and the maximum operating torque required used.
2. In the process 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 can be too frequent, that will eventually make Planetary reduction travel break the shaft.
Theoretically, the utmost operating torque required by the user must be significantly less than 2 times the rated output torque of the Planetary reduction drive, especially in some applications must strictly adhere to 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, when 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 a car motor will still make it constantly improve the output force, which might cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and thus twist the output shaft of the Planetary reduction drive.
