Planetary reduction drive is certainly a sort 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 wheel, and a gear ring, wherein the planetary steering wheel is supported by a fixed axis of the planetary framework, 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 guts of the planetary equipment transmission mechanism may be the sun wheel, the sun wheel and the earth wheel often engage, two external equipment meshing rotation direction is normally opposite.Just as the sun is at the center of the solar program, the solar wheel is named because of its location.Gear ring is the internal gear, it and the planet wheel often meshing, is the inner tooth and the external gear meshing, the rotation direction between the two is the same.The number of planetary gear depends on the look load of the Planetary reduction travel, usually 3 or 4, the more the quantity of bear the strain is greater.
The above is the Planetary reduction travel equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive can be a sort of speed of Planetary reduction drive, in that case, the planetary speed of Planetary reduction drive along the way of using the reason for the shaft break what?Let’s have a look.
1. The wrong type assortment 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 drive to meet up the work requirements could be, in fact, it is not, one is the rated outcome torque of the electric motor rated output torque instances deceleration ratio, the value obtained in principle ought to be less than the product sample to provide similar Planetary reduction travel rated result torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required used.
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 this sort of acceleration and deceleration is usually too frequent, that 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 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 main reason is that, when there is a problem in equipment installation, the output shaft of the Planetary reduction drive and its load are stuck, the overload capacity of the driving a car 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 so twist the output shaft of the Planetary reduction drive.
