Connection setting between of Planetary decrease drive and servo engine: holding mode – end result shaft of servo motor extends into of Planetary reduction drive, servo motor and Planetary reduction travel are connected by flange. There is a deformable hoop in Planetary decrease drive. By working the locking screw on Planetary decrease drive, the hoop can tighten the axis of the servo electric motor (the author has a 0.75KW servo electric motor with this connection). Consequently for this connection function, servo motors do not need keyway (of study course, keyway can also be, but buying keyway servo motors needs Money and delivery period are longer yo @ @). Some sort of
Connecting mode of_of Planetary reduction drive and servo engine: Connecting through exterior coupling. This connection mode uses exterior coupling, so it needs servo electric and keyway. External coupling can also use adaptable coupling (flexible shaft) – gentle shaft drive electricity generally does not surpass 5.5KW, speed may reach 20000 rpm. Some sort of

Planetary reduction travel in the use of the process there will be some noise, the emergence of the noise, how to deal with it?
The noise of Planetary reduction drive is mainly caused by the friction, vibration and collision of the transmission gears. How exactly to effectively reduce and decrease the noise to create it more in line with the requirements of environmental safety is also a key research topic in the home and overseas.Reducing the apparatus transmission noises of Planetary reduction travel has become a significant research matter in the market. Many scholars at home and abroad regard the change of gear tooth engagement stiffness in equipment transmission as the key factor of gear powerful load, vibration and noises.By modifying the shape, the dynamic load and velocity fluctuation are minimized to reduce the noise.This method has became more effective used.But with this method, the process will need shape modification equipment, nearly all small factories often can not be implemented.
Planetary reduction drive is usually a sort of of Planetary reduction travel, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sun wheel, a planetary wheel, and a gear band, wherein the planetary wheel is supported by a set axis of the planetary framework, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, sunlight wheel and the apparatus ring are in regular meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, sunlight wheel and the planet wheel frequently engage, two external gear meshing rotation direction is definitely opposite.Just as sunlight is at the guts of the solar system, the solar wheel is named for its location.Gear band is the internal gear, it and the planet wheel often meshing, is the interior tooth and the outer gear meshing, the rotation direction between the two may be the same.The number of planetary gear is determined by the design load of the Planetary reduction drive, usually three or four, the more the number of bear the strain is greater.
The above may be the Planetary reduction travel gear transmission structure of the key content.
Planetary speed of Planetary reduction drive is certainly a kind of speed of Planetary reduction drive, then, 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 outcome torque of the Planetary reduction drive.
Some users in the version selection, mistakenly as long as the selected rated end result torque Planetary reduction travel to meet the work requirements can be, in fact, it is not, one may be the rated output torque of the electric motor rated output torque situations deceleration ratio, the value obtained in principle should be less than the merchandise sample to provide similar Planetary reduction travel rated output torque.The other is to consider the overload capacity of the drive engine and the utmost operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the output shaft of the Planetary reduction drive exceeds 2 times of its rated output torque, and this kind of acceleration and deceleration is usually too frequent, that may eventually make Planetary decrease drive 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 a few applications must strictly comply with this criterion.This is simply 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, if there is a problem in equipment installation, the output shaft of the Planetary reduction travel and its own load are stuck, the overload capacity of the driving a car motor will still make it constantly boost 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 thus twist the output shaft of the Planetary reduction travel.

Listed below are the size and matching tolerance of the positioning boss, insight shaft and Planetary lowering travel groove of the electric motor.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, adapt the clamping band of PCS program to align the side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, take away the motor shaft keys.
The third step is to connect the engine with Planetary reduction travel normally.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the motor must be regular when connected, and the outer flange of the two must be parallel.If the concentricity is not consistent, the engine shaft will be broken or of Planetary decrease drive gear wear.
Furthermore, in the installation, do not use hammer and different blows, avoid the axial force or radial force an excessive amount of damage to the bearing or equipment.Make sure to tighten the mounting bolt just before tightening the induce 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 purpose is to make sure tight connection and overall flexibility of operation, and prevent unnecessary deterioration.
Before the motor and Planetary decrease drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, initial screw the unit installation bolts at any kind of diagonal position, but usually do not screw restricted, then screw the installation bolts at the various other two diagonal positions, and finally screw the four installation bolts one by one.Finally, tighten the force bolt.All tightening bolts shall be fixed and checked by the torque plate hand based on the indicated torque data.
Correct installation between of Planetary reduction drive and mechanical gear is the same as right installation between of Planetary reduction travel and drive motor.The main element is to make certain that the output shaft of Planetary reduction drive and the drive section of the shaft concentricity.
