Planetary reduction drive is usually a kind of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sun steering wheel, a planetary wheel, and a gear band, wherein the planetary wheel is supported by a set axis of the planetary frame, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in continuous meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the earth wheel quite often engage, two external gear meshing rotation direction is opposite.Just as the sun is at the guts of the solar program, the solar wheel is known as for its location.Gear ring is the internal 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 amount of planetary gear will depend on the look load of the Planetary reduction drive, usually 3 or 4, the more the number of bear the load is greater.
The above is the Planetary reduction travel gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a sort of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive in the process of using the reason for the shaft break what?Let’s take a look.
1. The wrong type selection causes insufficient outcome torque of the Planetary decrease drive.
Some users in the unit selection, mistakenly given that the selected rated result torque Planetary reduction drive to meet up the work requirements could be, in fact, it is not, one may be the rated result torque of the motor rated output torque moments deceleration ratio, the value obtained in principle should be less than the merchandise sample to provide similar Planetary reduction travel rated result 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 end result shaft of the Planetary lowering drive exceeds two times of its rated output torque, and these kinds of acceleration and deceleration is too frequent, that will eventually make Planetary lowering drive break the shaft.
Theoretically, the maximum operating torque required simply 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 comply with this criterion.This is simply not and then protect the Planetary reduction drive, but also to avoid the output shaft of Planetary reduction drive from being twisted off.The primary reason is that, if there is a problem in equipment installation, the output shaft of the Planetary reduction drive and its 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 travel to exceed its rated output torque two times and therefore twist the output shaft of the Planetary reduction drive.
