Planetary reduction drive is definitely a kind of of Planetary reduction travel, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear carries a sun steering wheel, a planetary wheel, and a gear ring, wherein the planetary 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 apparatus ring are in regular meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the earth wheel typically engage, two external equipment meshing rotation direction is certainly opposite.Just as sunlight is at the guts of the solar system, the solar wheel is known as because of its location.Gear ring is the inner gear, it and the earth wheel often meshing, is the internal tooth and the external gear meshing, the rotation direction between the two may be the same.The amount of planetary gear depends upon the look load of the Planetary reduction travel, usually 3 or 4, the more the amount of bear the strain is greater.
The above may be the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a kind of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive along the way of using the reason for the shaft break what?Let’s take a look.
1. The wrong type assortment causes insufficient end result torque of the Planetary decrease drive.
Some users in the style selection, mistakenly as long as the selected rated end result torque Planetary reduction travel to meet the work requirements could be, in fact, it is not, one is the rated productivity torque of the electric motor rated output torque times deceleration ratio, the worthiness obtained in principle should 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 utmost operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the output shaft of the Planetary lowering drive exceeds 2 times of its ranked output torque, and these kinds of acceleration and deceleration is usually too frequent, that will eventually make Planetary lowering drive break the shaft.
Theoretically, the utmost operating torque required simply by the user must be less than two times the rated output torque of the Planetary reduction drive, especially in some applications must strictly adhere to 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 main reason is that, if 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 a vehicle 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 2 times and so twist the output shaft of the Planetary reduction drive.
