Planetary reduction drive is definitely a kind of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun wheel, a planetary wheel, and a gear ring, wherein the planetary steering wheel is supported by a set axis of the planetary frame, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the gear ring are in regular meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the planet wheel frequently engage, two external equipment meshing rotation direction is normally 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 inner gear, it and the planet wheel often meshing, may be the interior tooth and the external gear meshing, the rotation direction between the two is the same.The number 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 travel equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a sort of speed of Planetary reduction drive, then, 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 selection causes insufficient end result torque of the Planetary reduction drive.
Some users in the model selection, mistakenly as long as the selected rated end result torque Planetary reduction drive to meet up the work requirements can be, in fact, it is not, one may be the rated end result torque of the electric motor rated output torque times deceleration ratio, the value obtained in principle should be less than the merchandise sample to supply similar Planetary reduction drive rated output torque.The other is to consider the overload capacity of the drive engine and the utmost operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the outcome shaft of the Planetary lowering drive exceeds two times of its rated output torque, and such acceleration and deceleration is usually too frequent, which will eventually make Planetary reduction drive break the shaft.
Theoretically, the maximum operating torque required by an individual 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 not only to 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, when there is a problem in equipment installation, the output shaft of the Planetary reduction travel and its load are stuck, the overload capacity of the driving motor will still make it constantly raise the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque 2 times and therefore twist the output shaft of the Planetary reduction drive.
