Planetary reduction drive is normally a kind of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun steering wheel, a planetary wheel, and a gear ring, wherein the planetary wheel is supported by a set axis of the planetary framework, allowing the planetary steering wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the apparatus ring are in frequent meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the earth wheel sometimes engage, two external gear meshing rotation direction is usually opposite.Just as sunlight is at the guts of the solar program, the solar wheel is known as for its location.Gear ring is the interior gear, it and the earth wheel often meshing, may be the internal tooth and the outer gear meshing, the rotation direction between your two is the same.The amount of planetary gear will depend on the look load of the Planetary reduction drive, usually three or four, the more the quantity of bear the load is greater.
The above may be the Planetary reduction drive equipment transmission structure of the primary content.
Planetary speed of Planetary reduction drive is 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 have a look.
1. The wrong type assortment causes insufficient outcome torque of the Planetary lowering drive.
Some users in the style selection, mistakenly provided that the selected rated result torque Planetary reduction drive to meet up the work requirements can be, in fact, it is not, one may be the rated output torque of the electric motor rated output torque occasions deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise sample to supply similar Planetary reduction drive rated outcome torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the output shaft of the Planetary reduction drive exceeds 2 times of its ranked output torque, and these kinds of acceleration and deceleration is too frequent, which will eventually make Planetary reduction travel break the shaft.
Theoretically, the maximum operating torque required simply by the user 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 avoid 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 travel and its own load are stuck, the overload capacity of the generating motor will still make it constantly raise 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 so twist the output shaft of the Planetary reduction travel.
