Planetary reduction drive is definitely a kind of of Planetary reduction travel, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear carries a sun steering 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 gear ring are in continuous meshing state.
Located in the center of the planetary gear transmission mechanism may be the sun wheel, the sun wheel and the planet wheel frequently engage, two external gear meshing rotation direction is normally opposite.Just as sunlight is at the center of the solar system, the solar wheel is known as for its location.Gear ring is the internal gear, it and the planet wheel often meshing, is the inner tooth and the outer gear meshing, the rotation direction between the two is the same.The quantity of planetary gear is determined by the design load of the Planetary reduction travel, usually 3 or 4, the more the quantity of bear the load is greater.
The above is 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, after that, the planetary speed of Planetary reduction drive in the process of using the cause of the shaft break what?Let’s have a look.
1. The wrong type selection causes insufficient output torque of the Planetary decrease drive.
Some users in the unit selection, mistakenly as long as the selected rated result torque Planetary reduction travel to meet up the work requirements can be, in fact, it is not, one may be the rated result torque of the engine rated output torque occasions deceleration ratio, the worthiness obtained in principle should be less than the merchandise sample to provide similar Planetary reduction drive rated output 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 end result shaft of the Planetary decrease drive exceeds two times of its ranked output torque, and such acceleration and deceleration is definitely too frequent, that may eventually make Planetary decrease travel break the shaft.
Theoretically, the maximum operating torque required by an individual 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 simply 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 drive and its load are stuck, the overload capacity of the driving motor will still make it constantly increase the output force, which may 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 drive.
