Planetary reduction drive is definitely a kind of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun steering wheel, a planetary steering wheel, and a gear band, wherein the planetary wheel is supported by a set axis of the planetary framework, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, sunlight wheel and the apparatus ring are in frequent meshing state.
Located in the guts of the planetary equipment transmission mechanism may be the sun wheel, the sun wheel and the earth wheel quite often engage, two external gear meshing rotation direction is usually opposite.Just as sunlight is at the center of the solar system, the solar wheel is known as for its location.Gear band is the internal gear, it and the planet wheel often meshing, may be the interior tooth and the external gear meshing, the rotation direction between your two may be the same.The quantity of planetary gear depends upon the look load of the Planetary reduction drive, usually three or four, the more the number of bear the load is greater.
The above is the Planetary reduction travel gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a sort of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive in the process 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 decrease drive.
Some users in the model selection, mistakenly given that the selected rated productivity torque Planetary reduction travel to meet up the work requirements can be, in fact, it isn’t, one may be the rated outcome torque of the motor rated output torque moments deceleration ratio, the worthiness 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 engine and the maximum operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the productivity shaft of the Planetary reduction drive exceeds two times of its ranked output torque, and such acceleration and deceleration is definitely too frequent, that will eventually make Planetary lowering travel break the shaft.
Theoretically, the maximum operating torque required by the user must be less than two times the rated output torque of the Planetary reduction drive, especially in a few applications must strictly adhere to this criterion.This is simply not and then 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 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 thus twist the output shaft of the Planetary reduction drive.
