Planetary reduction drive is definitely a sort of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun steering wheel, a planetary steering wheel, and a gear ring, wherein the planetary wheel is supported by a set axis of the planetary frame, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, the sun wheel and the apparatus 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 sometimes engage, two external gear meshing rotation direction is certainly opposite.Just as sunlight is at the center of the solar program, the solar wheel is known as because of its location.Gear ring is the interior gear, it and the planet wheel often meshing, is the interior tooth and the external gear meshing, the rotation direction between the two may be the same.The quantity of planetary gear depends on the design load of the Planetary reduction travel, usually 3 or 4, the more the quantity of bear the strain is greater.
The above is the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive can be a kind of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive along the way of using the cause of the shaft break what?Let’s have a look.
1. The wrong type collection causes insufficient outcome torque of the Planetary reduction drive.
Some users in the model selection, mistakenly provided that the selected rated output torque Planetary reduction drive to meet up the work requirements can be, in fact, it isn’t, one may be the rated output torque of the engine rated output torque instances deceleration ratio, the worthiness obtained in principle should be less than the merchandise sample to provide similar Planetary reduction travel rated result torque.The other is to consider the overload capacity of the drive motor and the utmost operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary reduction drive exceeds 2 times of its rated output torque, and such acceleration and deceleration is normally too frequent, that will eventually make Planetary lowering travel break the shaft.
Theoretically, the maximum 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 adhere to 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 main 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 motor will still make it constantly boost the output force, which might 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.

With the Ever-Electricity mountain drive you get additional very low gears which allow you go climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to confirm whether the engine and Planetary reduction drive are in good condition before installation, and strictly check if the size of each part connected with the motor and Planetary reduction travel is matched. Here are the size and matching tolerance of the positioning boss, suggestions shaft and Planetary decrease travel groove of the engine.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary reduction drive flange, modify the clamping ring of PCS system to align the medial side hole with the dustproof hole, insert the internal hexagon to tighten.After that, take away the motor shaft keys.
The 3rd step is to connect the engine with Planetary reduction drive naturally.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the electric motor must be regular when connected, and the external flange of the two must be parallel.If the concentricity is not consistent, the motor shaft will be broken or of Planetary lowering drive gear wear.
In addition, in the installation, usually do not use hammer and additional blows, avoid the axial force or radial force an excessive amount of damage to the bearing or equipment.Be sure to tighten the installation bolt ahead of tightening the force bolt.Before installation, wipe aside the anti-corrosion oil of motor input shaft, positioning boss and connecting part of of Planetary reduction drive with gasoline or zinc-sodium water.Its goal is to make sure tight connection and versatility of operation, and stop unnecessary deterioration.
Prior to the motor and Planetary decrease drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, first screw the unit installation bolts at virtually any diagonal position, but usually do not screw restricted, then screw the assembly bolts at the additional two diagonal positions, and finally screw the four unit installation bolts one by one.Finally, tighten the force bolt.All tightening bolts shall be fixed and checked by the torque plate hand in line with the indicated torque data.
Accurate installation between of Planetary reduction travel and mechanical devices is the same as right installation between of Planetary reduction drive and drive motor.The main element is to make certain that the output shaft of Planetary reduction drive and the drive portion of the shaft concentricity.
