Planetary reduction drive is a kind of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear carries 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 body, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, the sun wheel and the apparatus ring are in frequent meshing state.
Located in the guts of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the planet wheel often engage, two external equipment meshing rotation direction is certainly opposite.Just as the sun is at the guts of the solar program, the solar wheel is named for its location.Gear band is the interior gear, it and the planet wheel often meshing, is the interior tooth and the outer gear meshing, the rotation direction between the two may be the same.The number of planetary gear is determined by the design load of the Planetary reduction travel, usually three or four, the more the quantity 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 normally a kind of speed of Planetary reduction drive, then, 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 output torque of the Planetary reduction drive.
Some users in the unit selection, mistakenly given that the selected rated outcome torque Planetary reduction drive to meet the work requirements could be, in fact, it is not, one is the rated outcome torque of the engine rated output torque times deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise sample to provide similar Planetary reduction travel rated productivity torque.The other is to consider the overload capacity of the drive electric motor and the maximum 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 two times of its ranked output torque, and this kind of acceleration and deceleration is normally too frequent, that may eventually make Planetary decrease drive break the shaft.
Theoretically, the utmost operating torque required 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 travel and its load are stuck, the overload capacity of the driving a car motor will still make it constantly increase the output force, which might 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 travel.
