Planetary reduction drive can be a sort of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun wheel, a planetary wheel, and a gear band, wherein the planetary steering wheel is supported by a set axis of the planetary frame, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the apparatus ring are in constant meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, sunlight wheel and the earth wheel typically engage, two external gear meshing rotation direction is opposite.Just as the sun is at the center of the solar system, the solar wheel is known as because of 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 amount of planetary gear is determined by the look load of the Planetary reduction drive, usually three or four, the more the quantity of bear the load is greater.
The above is the Planetary reduction travel gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is a kind 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 collection causes insufficient output torque of the Planetary lowering drive.
Some users in the model selection, mistakenly given that the selected rated productivity torque Planetary reduction drive to meet the work requirements can be, in fact, it isn’t, one is the rated result torque of the electric motor rated output torque times deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise sample to supply similar Planetary reduction travel rated output torque.The other is to consider the overload capacity of the drive engine and the utmost operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the productivity shaft of the Planetary decrease drive exceeds two times of its rated output torque, and these kinds of acceleration and deceleration is normally too frequent, that will eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required by the user must be 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 main 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 vehicle motor will still make it constantly increase the output force, which might 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 travel.
