Planetary reduction drive is usually 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 wheel, a planetary wheel, and a gear ring, wherein the planetary steering wheel is supported by a set axis of the planetary framework, allowing the planetary steering wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the apparatus ring are in frequent meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, the sun wheel and the earth wheel sometimes 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 named because of its location.Gear ring is the interior gear, it and the earth 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 is determined by the design 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 is a sort of speed of Planetary reduction drive, in that case, the planetary speed of Planetary reduction drive in the process of using the cause of the shaft break what?Let’s take a look.
1. The wrong type collection causes insufficient outcome torque of the Planetary lowering drive.
Some users in the style selection, mistakenly given that the selected rated end result torque Planetary reduction travel to meet up the work requirements can be, in fact, it isn’t, one may be the rated productivity torque of the electric motor rated output torque situations deceleration ratio, the worthiness obtained in principle should be less than the merchandise sample to provide similar Planetary reduction drive rated productivity torque.The other is to consider the overload capacity of the drive engine and the maximum operating torque required used.
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 these kinds of acceleration and deceleration can be too frequent, which will eventually make Planetary reduction drive break the shaft.
Theoretically, the utmost operating torque required by an individual 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 and then 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, if 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 generating motor will still make it constantly boost the output force, which might 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.
