Connection method between of Planetary lowering drive and servo engine: holding mode – result shaft of servo electric motor extends into of Planetary decrease drive, servo engine and Planetary reduction travel are linked by flange. You will find a deformable hoop in Planetary decrease drive. By working the locking screw on Planetary reduction travel, the hoop can tighten the axis of the servo electric motor (the author includes a 0.75KW servo motor with this connection). So for this connection setting, servo motors usually do not require keyway (of training course, keyway can also be, but purchasing keyway servo motors needs Money and delivery period are longer yo @ @). A kind of
Connecting mode of_of Planetary decrease drive and servo electric motor: Connecting through exterior coupling. This connection setting uses exterior coupling, so that it needs servo electric and keyway. Exterior coupling may also use versatile coupling (flexible shaft) – delicate shaft drive power generally does not exceed 5.5KW, speed can reach 20000 rpm. A kind of
In most cases, the servo motors without brakes and keyways will be the many used and the Ever-Power may be the largest. For that reason, to buy the servo motors with brakes and keyways, the delivery period is longer, about 4 weeks.
Planetary reduction drive in the usage of the process there will be some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction travel is mainly due to the friction, vibration and collision of the transmission gears. How to effectively reduce and reduce the noise to make it more in line with the requirements of environmental protection is also a key research topic in the home and overseas.Reducing the gear transmission noises of Planetary reduction travel has become an important research issue in the market. Many scholars at home and abroad respect the change of gear tooth engagement stiffness in equipment transmission as the key factor of gear dynamic 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 in practice.But with this technique, the process will need shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive is 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 wheel, a planetary steering wheel, and a gear band, wherein the planetary wheel is supported by a set axis of the planetary body, allowing the planetary steering wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the gear ring are in continuous meshing state.
Located in the center of the planetary equipment transmission mechanism may be the sun wheel, the sun wheel and the planet wheel sometimes engage, two external gear meshing rotation direction is opposite.Just as the sun is at the center of the solar program, the solar wheel is named because of its location.Gear ring is the interior gear, it and the earth wheel often meshing, is the internal tooth and the external gear meshing, the rotation direction between the two is the same.The quantity of planetary gear will depend on the design load of the Planetary reduction travel, 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 definitely a sort of speed of Planetary reduction drive, then, 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 assortment causes insufficient outcome torque of the Planetary decrease drive.
Some users in the version selection, mistakenly provided that the selected rated outcome torque Planetary reduction travel to meet up the work requirements can be, in fact, it is not, one may be the rated outcome torque of the electric motor rated output torque circumstances deceleration ratio, the value obtained in principle should be less than the merchandise sample to supply similar Planetary reduction travel rated outcome torque.The other is to consider the overload capacity of the drive motor and the maximum operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the end result shaft of the Planetary decrease drive exceeds two times of its ranked output torque, and this kind of acceleration and deceleration is definitely too frequent, that may eventually make Planetary lowering drive break the shaft.
Theoretically, the maximum operating torque required simply by an individual must be significantly 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 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, when 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 driving a vehicle motor will still make it constantly improve the output force, which might cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque 2 times and therefore twist the output shaft of the Planetary reduction travel.

Here are the size and complementing tolerance of the positioning boss, source shaft and Planetary lowering travel groove of the motor.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary reduction drive flange, adapt the clamping band of PCS system to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.After that, remove the motor shaft keys.
The 3rd step is to hook up the engine with Planetary reduction drive in a natural way.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be regular when connected, and the external flange of both should be parallel.If the concentricity isn’t consistent, the motor shaft will be broken or of Planetary lowering drive gear wear.
Furthermore, in the installation, usually do not use hammer and other blows, prevent the axial force or radial force too much harm to the bearing or gear.Make sure to tighten the mounting bolt just before tightening the drive bolt.Before installation, wipe apart the anti-rust oil of motor input shaft, positioning boss and connecting component of of Planetary reduction drive with gasoline or zinc-sodium water.Its goal is to make sure tight connection and overall flexibility of operation, and prevent unnecessary deterioration.
Prior to the motor and Planetary reduction drive are linked, the motor shaft keyway ought to be perpendicular to the tightening bolt.To ensure a uniform force, primary screw the installation bolts at any diagonal position, but do not screw tight, then screw the assembly bolts at the different two diagonal positions, and lastly screw the four unit installation bolts one at a time.Finally, tighten the force bolt.All tightening bolts will be fixed and checked by the torque plate hand according to the indicated torque data.
Correct installation between of Planetary reduction drive and mechanical tools is equivalent to appropriate installation between of Planetary reduction drive and drive motor.The key is to make sure that the output shaft of Planetary reduction drive and the drive part of the shaft concentricity.
