Planetary reduction drive is certainly a kind of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun steering wheel, a planetary steering wheel, and a gear band, wherein the planetary steering wheel is supported by a set axis of the planetary body, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the apparatus ring are in continuous meshing state.
Located in the guts of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the earth wheel generally engage, two external equipment meshing rotation direction can be 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 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 amount of planetary gear will depend on the design load of the Planetary reduction drive, usually 3 or 4, the more the amount of bear the load is greater.
The above may be 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, in that case, 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 assortment causes insufficient end result torque of the Planetary decrease drive.
Some users in the version selection, mistakenly so long as the selected rated output torque Planetary reduction travel to meet up the work requirements can be, in fact, it isn’t, one may be the rated end result torque of the electric motor rated output torque circumstances deceleration ratio, the worthiness obtained in principle ought to be less than the product sample to provide similar Planetary reduction travel rated productivity torque.The other is to consider the overload capacity of the drive motor and the utmost operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary decrease drive exceeds two times of its ranked output torque, and these kinds of acceleration and deceleration is definitely too frequent, that will eventually make Planetary lowering drive break the shaft.
Theoretically, the utmost operating torque required by the user must be less than 2 times the rated output torque of the Planetary reduction drive, especially in a few applications must strictly adhere to this criterion.This is not only to 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 travelling 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 so twist the output shaft of the Planetary reduction travel.
