Planetary reduction drive is a sort of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun wheel, a planetary wheel, and a gear ring, wherein the planetary steering wheel is supported by a set axis of the planetary frame, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the apparatus ring are in constant meshing state.
Located in the guts of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the earth wheel sometimes engage, two external gear meshing rotation direction is usually opposite.Just as sunlight is at the center of the solar program, the solar wheel is known as because of its location.Gear band is the inner gear, it and the planet wheel often meshing, may be the internal tooth and the external gear meshing, the rotation direction between the 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 quantity of bear the strain is greater.
The above is the Planetary reduction drive gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a kind of speed of Planetary reduction drive, in that case, 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 result torque of the Planetary reduction drive.
Some users in the unit selection, mistakenly as long as the selected rated outcome torque Planetary reduction drive to meet up the work requirements can be, in fact, it is not, one is the rated end result torque of the engine rated output torque occasions deceleration ratio, the value obtained in principle ought to be less than the product sample to provide similar Planetary reduction drive rated productivity torque.The other is to consider the overload capacity of the drive engine and the utmost operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the productivity shaft of the Planetary reduction drive exceeds 2 times of its rated output torque, and these kinds of acceleration and deceleration is definitely too frequent, which will eventually make Planetary reduction travel break the shaft.
Theoretically, the maximum 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 only to protect the Planetary reduction drive, but also to avoid 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 drive and its 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 travel to exceed its rated output torque 2 times and thus twist the output shaft of the Planetary reduction travel.
