Planetary reduction drive is definitely a kind of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun steering wheel, a planetary steering wheel, and a gear ring, wherein the planetary steering wheel is supported by a fixed axis of the planetary body, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, the sun wheel and the gear ring are in continuous meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, the sun wheel and the earth wheel quite often engage, two external equipment meshing rotation direction is normally opposite.Just as the sun is at the center of the solar program, the solar wheel is known as because of its location.Gear ring is the inner gear, it and the earth wheel often meshing, may be the internal tooth and the external gear meshing, the rotation direction between your two is the same.The quantity of planetary gear depends upon the design load of the Planetary reduction drive, usually three or four, the more the amount of bear the load is greater.
The above is the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is usually 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 assortment causes insufficient productivity torque of the Planetary lowering drive.
Some users in the style selection, mistakenly so long as the selected rated outcome torque Planetary reduction travel to meet the work requirements could be, in fact, it isn’t, one is the rated end result torque of the motor rated output torque occasions deceleration ratio, the worthiness obtained in principle ought to be less than the product sample to supply similar Planetary reduction drive rated outcome torque.The other is to consider the overload capacity of the drive motor 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 reduction drive exceeds two times of its ranked output torque, and such acceleration and deceleration is certainly too frequent, that will eventually make Planetary reduction travel break the shaft.
Theoretically, the maximum operating torque required simply by an individual must be significantly less than two 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 primary reason is that, when 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 traveling 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 so twist the output shaft of the Planetary reduction travel.
