A planetary gear carries a sun wheel, a planetary steering wheel, and a gear ring, wherein the planetary wheel is supported by a fixed axis of the planetary framework, allowing the planetary steering wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the gear ring are in continuous meshing state.
Located in the guts of the planetary equipment transmission mechanism is the sun wheel, the sun wheel and the earth wheel often engage, two external gear meshing rotation direction can be opposite.Just as the sun is at the guts of the solar program, the solar wheel is known as because of its location.Gear band is the interior gear, it and the earth wheel often meshing, may be the inner tooth and the external gear meshing, the rotation direction between your two is the same.The quantity of planetary gear is determined by the look load of the Planetary reduction drive, usually 3 or 4, the more the amount of bear the load is greater.
The above is the Planetary reduction travel gear 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 along the way of using the reason for the shaft break what?Let’s have a look.
1. The wrong type variety causes insufficient 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 drive to meet up the work requirements could 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 product sample to provide similar Planetary reduction travel rated end result torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the end result shaft of the Planetary lowering drive exceeds 2 times of its ranked output torque, and this kind of acceleration and deceleration can be too frequent, which will eventually make Planetary decrease travel break the shaft.
Theoretically, the utmost operating torque required simply by the user 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 not and then protect the Planetary reduction drive, but also to prevent 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 travel and its load are stuck, the overload capacity of the traveling 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 2 times and so twist the output shaft of the Planetary reduction drive.
