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 body, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the gear ring are in regular meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, sunlight wheel and the planet wheel often engage, two external gear meshing rotation direction can be opposite.Just as sunlight is at the center of the solar program, the solar wheel is named for its location.Gear band is the internal gear, it and the planet wheel often meshing, may be the internal tooth and the outer gear meshing, the rotation direction between your two may be the same.The number of planetary gear will depend on the design load of the Planetary reduction drive, usually 3 or 4, the more the quantity of bear the strain is greater.
The above may be the Planetary reduction travel equipment transmission structure of the key content.
Planetary speed of Planetary reduction drive is usually 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 assortment causes insufficient productivity torque of the Planetary decrease drive.
Some users in the version selection, mistakenly given that the selected rated productivity torque Planetary reduction drive to meet the work requirements could be, in fact, it isn’t, one may be the rated output torque of the engine rated output torque instances deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise sample to supply similar Planetary reduction drive rated result torque.The other is to consider the overload capacity of the drive motor and the utmost operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the end result shaft of the Planetary decrease drive exceeds 2 times of its rated output torque, and these kinds of acceleration and deceleration is normally too frequent, that may eventually make Planetary decrease travel break the shaft.
Theoretically, the utmost operating torque required simply by the user 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 simply not only to 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 driving a car 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 two times and thus twist the output shaft of the Planetary reduction drive.
