Planetary reduction drive is normally a kind of of Planetary reduction travel, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun wheel, a planetary steering wheel, and a gear band, wherein the planetary wheel is supported by a fixed axis of the planetary body, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in frequent meshing state.
Located in the guts of the planetary equipment transmission mechanism may be the sun wheel, sunlight wheel and the earth wheel typically engage, two external equipment meshing rotation direction is opposite.Just as sunlight is at the guts of the solar program, the solar wheel is known as because of its location.Gear band is the inner gear, it and the earth wheel often meshing, is the inner tooth and the external gear meshing, the rotation direction between your two is the same.The quantity of planetary gear will depend on the look load of the Planetary reduction drive, usually 3 or 4, the more the quantity of bear the strain is greater.
The above may be the Planetary reduction drive gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is a kind of speed of Planetary reduction drive, then, the planetary speed of Planetary reduction drive in the process of using the reason for the shaft break what?Let’s take a look.
1. The wrong type collection causes insufficient outcome torque of the Planetary decrease drive.
Some users in the version selection, mistakenly given that the selected rated result torque Planetary reduction drive to meet the work requirements can be, in fact, it is not, one may be the rated productivity torque of the electric motor rated output torque occasions deceleration ratio, the value obtained in principle ought to be less than the merchandise sample to supply similar Planetary reduction drive rated end result torque.The other is to consider the overload capacity of the drive motor and the maximum operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the end result shaft of the Planetary reduction drive exceeds 2 times of its rated output torque, and such acceleration and deceleration is too frequent, that will eventually make Planetary lowering travel break the shaft.
Theoretically, the maximum operating torque required simply by an individual must be significantly less than 2 times the rated output torque of the Planetary reduction drive, especially in some applications must strictly adhere to 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 motor will still make it constantly improve 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 travel.
