Connection mode between of Planetary lowering drive and servo motor: holding mode – output shaft of servo motor extends into of Planetary decrease drive, servo engine and Planetary reduction drive are linked by flange. There is a deformable hoop in Planetary lowering drive. By working the locking screw on Planetary reduction drive, the hoop can tighten the axis of the servo electric motor (the author has a 0.75KW servo engine with this connection). And so for this connection function, servo motors do not require keyway (of lessons, keyway may also be, but purchasing keyway servo motors needs Money and delivery period are longer yo @ @). A kind of
Linking mode of_of Planetary decrease drive and servo electric motor: Connecting through external coupling. This connection function uses external coupling, so it needs servo electric and keyway. Exterior coupling can also use adaptable coupling (flexible shaft) – gentle shaft drive ability generally does not go beyond 5.5KW, speed may reach 20000 rpm. Some sort of
Generally speaking, the servo motors without brakes and keyways will be the many used and the Ever-Power may be the largest. For this reason, to purchase the servo motors with brakes and keyways, the delivery period is longer, about 4 weeks.
Planetary reduction travel in the utilization of the process you will see some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction travel is mainly caused by the friction, vibration and collision of the transmission gears. How exactly to successfully reduce and reduce the noise to make it more good requirements of environmental safeguard is also a key research topic at home and overseas.Reducing the apparatus transmission sound of Planetary reduction drive has become a significant research matter in the industry. Many scholars at home and abroad respect the change of gear tooth engagement stiffness in equipment transmission as the key factor of gear powerful load, vibration and sound.By modifying the form, the powerful load and velocity fluctuation are minimized to reduce the noise.This technique has became more effective used.But with this technique, the process needs to have shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive is normally a kind of of Planetary reduction travel, what is 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 wheel is supported by a fixed axis of the planetary body, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, sunlight wheel and the apparatus ring are in constant meshing state.
Located in the center of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the planet wheel often engage, two external gear meshing rotation direction is certainly opposite.Just as the sun is at the guts of the solar system, the solar wheel is known as because of its location.Gear ring is the internal gear, it and the planet wheel often meshing, may be the interior tooth and the external gear meshing, the rotation direction between your two may be the same.The amount of planetary gear depends upon the look load of the Planetary reduction drive, usually 3 or 4, the more the amount of bear the strain is greater.
The above may be the Planetary reduction travel equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is certainly a kind of speed of Planetary reduction drive, in that case, the planetary speed of Planetary reduction drive along the way 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 lowering drive.
Some users in the model selection, mistakenly given that the selected rated productivity torque Planetary reduction travel to meet the work requirements could be, in fact, it is not, one may be the rated outcome torque of the engine rated output torque situations deceleration ratio, the worthiness obtained in principle ought to be less than the product sample to supply similar Planetary reduction travel rated outcome 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 2 times of its ranked output torque, and these kinds of acceleration and deceleration is normally too frequent, that may 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 some applications must strictly adhere to this criterion.This is simply not only to 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 drive and its load are stuck, the overload capacity of the travelling motor will still make it constantly raise the output force, which might 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 drive.

Here are the size and complementing tolerance of the positioning boss, suggestions shaft and Planetary decrease drive groove of the engine.
Step two 2: unscrew the screw on the external dustproof hole of of Planetary decrease drive flange, adjust the clamping ring of PCS system to align the side hole with the dustproof hole, insert the internal hexagon to tighten.From then on, remove the motor shaft keys.
The third step is to hook up the motor with Planetary reduction drive normally.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be constant when connected, and the external flange of the two should be parallel.If the concentricity isn’t consistent, the motor shaft will be broken or of Planetary reduction drive gear wear.
Furthermore, in the installation, do not use hammer and additional blows, avoid the axial force or radial force an excessive amount of damage to the bearing or gear.Make sure you tighten the installation bolt prior to tightening the power bolt.Before installation, wipe apart the anti-rust oil of motor input shaft, positioning boss and connecting portion of of Planetary reduction drive with gasoline or zinc-sodium water.Its purpose is to make sure tight connection and flexibility of operation, preventing unnecessary wear and tear.
Before the motor and Planetary reduction drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, initial screw the unit installation bolts at virtually any diagonal position, but usually do not screw restricted, then screw the set up bolts at the various other two diagonal positions, and lastly screw the four unit installation bolts one at a time.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 drive and mechanical tools is equivalent to correct installation between of Planetary reduction travel and drive engine.The key is to make sure that the output shaft of Planetary reduction drive and the drive area of the shaft concentricity.
