Planetary reduction drive is normally a kind of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sun steering wheel, a planetary steering wheel, and a gear band, wherein the planetary wheel is supported by a fixed axis of the planetary framework, allowing the planetary steering wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the apparatus ring are in continuous meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the planet wheel sometimes engage, two external gear meshing rotation direction is definitely opposite.Just as the sun is at the center of the solar system, the solar wheel is named for its location.Gear ring is the interior gear, it and the planet wheel often meshing, may be the inner tooth and the outer gear meshing, the rotation direction between the two is the same.The quantity of planetary gear depends upon the look load of the Planetary reduction travel, usually three or four, the more the number of bear the strain is greater.
The above is the Planetary reduction drive equipment transmission structure of the key content.
Planetary speed of Planetary reduction drive is definitely a kind 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 result torque of the Planetary reduction drive.
Some users in the unit selection, mistakenly as long as the selected rated output torque Planetary reduction travel to meet the work requirements can be, in fact, it is not, one may be the rated end result torque of the motor rated output torque instances deceleration ratio, the worthiness obtained in principle should be less than the merchandise sample to provide similar Planetary reduction drive rated end result torque.The other is to consider the overload capacity of the drive electric motor and the utmost operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary lowering drive exceeds 2 times of its rated output torque, and this sort of acceleration and deceleration is usually too frequent, which will eventually make Planetary lowering travel break the shaft.
Theoretically, the utmost operating torque required simply 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 comply with this criterion.This is not only to 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 travel and its own load are stuck, the overload capacity of the driving motor will still make it constantly boost the output force, which may cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque two times and therefore twist the output shaft of the Planetary reduction travel.
