Planetary reduction drive can be a sort of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun wheel, a planetary steering 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 helping axis.The planetary wheel, sunlight wheel and the apparatus ring are in continuous meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, the sun wheel and the earth wheel frequently engage, two external equipment meshing rotation direction is usually opposite.Just as sunlight is at the guts of the solar program, the solar wheel is known as for its location.Gear band is the interior gear, it and the planet wheel often meshing, may be the inner tooth and the outer gear meshing, the rotation direction between the two is the same.The quantity of planetary gear will depend on the design load of the Planetary reduction drive, usually three or four, the more the quantity of bear the load is greater.
The above is the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a sort 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 have a look.
1. The wrong type collection causes insufficient productivity torque of the Planetary lowering drive.
Some users in the style selection, mistakenly provided that the selected rated result torque Planetary reduction travel to meet up the work requirements could be, in fact, it isn’t, one may be the rated outcome torque of the motor rated output torque situations deceleration ratio, the value obtained in principle should be less than the product sample to supply similar Planetary reduction drive rated output torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the productivity 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, that will eventually make Planetary decrease travel break the shaft.
Theoretically, the utmost operating torque required simply by the user must be significantly less than two times the rated output torque of the Planetary reduction drive, especially in a few 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, when there is a problem in equipment installation, the output shaft of the Planetary reduction drive and its own load are stuck, the overload capacity of the driving a vehicle motor will still make it constantly increase the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and so twist the output shaft of the Planetary reduction travel.
