Planetary reduction drive can be a kind of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun steering wheel, a planetary steering wheel, and a gear ring, wherein the planetary 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 frequent meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the planet wheel generally engage, two external gear meshing rotation direction is certainly opposite.Just as the sun is at the guts of the solar system, the solar wheel is known as because of its location.Gear band is the interior gear, it and the planet wheel often meshing, may be the interior tooth and the external gear meshing, the rotation direction between your two is the same.The number of planetary gear is determined by the look load of the Planetary reduction travel, usually 3 or 4, the more the quantity of bear the load is greater.
The above may be the Planetary reduction travel gear transmission structure of the primary 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 in the process of using the reason for the shaft break what?Let’s have a look.
1. The wrong type assortment causes insufficient result torque of the Planetary decrease drive.
Some users in the unit selection, mistakenly provided that the selected rated result torque Planetary reduction travel to meet the work requirements could be, in fact, it isn’t, one may be the rated result torque of the electric motor rated output torque moments deceleration ratio, the value obtained in principle ought to be less than the merchandise sample to supply similar Planetary reduction travel rated result torque.The other is to consider the overload capacity of the drive motor and the utmost operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the outcome shaft of the Planetary reduction drive exceeds two times of its rated output torque, and these kinds of acceleration and deceleration is certainly too frequent, that may eventually make Planetary decrease drive 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 not and then 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, if there is a problem in equipment installation, the output shaft of the Planetary reduction drive and its own load are stuck, the overload capacity of the traveling motor will still make it constantly improve 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 thus twist the output shaft of the Planetary reduction drive.
