Connection setting between of Planetary decrease drive and servo electric motor: holding mode – end result shaft of servo electric motor extends into of Planetary decrease drive, servo electric motor and Planetary reduction travel are connected by flange. You will find a deformable hoop in Planetary reduction drive. By operating the locking screw on Planetary lowering drive, the hoop can tighten the axis of the servo engine (the author includes a 0.75KW servo motor with this connection). Hence for this connection mode, servo motors usually do not need keyway (of course, keyway can also be, but buying keyway servo motors requires Money and delivery time are longer yo @ @). A kind of
Connecting mode of_of Planetary lowering drive and servo electric motor: Connecting through exterior coupling. This connection method uses external coupling, so it needs servo electrical and keyway. Exterior coupling can also use versatile coupling (flexible shaft) – gentle shaft drive vitality generally does not go beyond 5.5KW, speed can reach 20000 rpm. Some sort of
Generally speaking, the servo motors without brakes and keyways will be the the majority of used and the Ever-Power is the largest. For this reason, to buy the servo motors with brakes and keyways, the delivery period is longer, about 4 weeks.
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 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 proper protection is also a key research topic in the home and abroad.Reducing the apparatus transmission noise of Planetary reduction travel has become a crucial research subject matter in the industry. Many scholars in the home and abroad regard the change of gear tooth engagement stiffness in gear transmission as the primary factor of gear dynamic load, vibration and sound.By modifying the form, the dynamic load and velocity fluctuation are minimized to reduce the noise.This method has proved to be more effective used.But with this technique, the process needs to have shape modification equipment, the majority of small factories often can not be implemented.
Planetary reduction drive is usually 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 wheel, a planetary steering 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, sunlight wheel and the gear ring are in constant meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the earth wheel generally engage, two external gear meshing rotation direction is normally opposite.Just as the sun is at the center of the solar program, the solar wheel is named for its location.Gear ring is the inner gear, it and the earth wheel often meshing, may be the internal tooth and the external gear meshing, the rotation direction between your two is the same.The quantity of planetary gear depends upon the look load of the Planetary reduction drive, usually three or four, the more the number of bear the load is greater.
The above may be the Planetary reduction drive gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is definitely a sort 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 selection causes insufficient end result torque of the Planetary decrease drive.
Some users in the version selection, mistakenly as long as the selected rated productivity torque Planetary reduction drive to meet up the work requirements can be, in fact, it is not, one may be the rated output torque of the electric motor rated output torque instances deceleration ratio, the value obtained in principle should 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 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 reduction drive exceeds 2 times of its rated output torque, and these kinds of acceleration and deceleration is usually too frequent, that will eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required simply by the user must be 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 main reason is that, when 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 may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and therefore twist the output shaft of the Planetary reduction drive.
Precision planetary reduction drive
Product Description:
There are two main types based on the output direction: right type and proper angle type; Planetary gear systems are used to execute speed reduction because of significant torque. to predict gear noise from a rear wheel drive automated transmission.
There are usually three types in line with the number of stages: one-stage deceleration (generally less than 10:1), two-stage deceleration (generally greater than 10:1 and less than or add up to 100:1), and three-stage deceleration (large reduction ratio is 100) :1, the general division principle is higher than 100:1);
According to the purpose: military and civilian;In line with the operating environment: common environment, low temperatures environment, clean place environment and vacuum environment;

With the Ever-Ability mountain drive you gain additional very low gears which allow you go climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The first step is to verify whether the engine and Planetary reduction travel are in good shape before installation, and strictly check whether the size of each part connected with the electric motor and Planetary reduction travel is matched. Listed below are the size and complementing tolerance of the positioning boss, suggestions shaft and Planetary decrease travel groove of the motor.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary decrease drive flange, adjust the clamping band of PCS system to align the side hole with the dustproof hole, insert the interior hexagon to tighten.After that, take away the motor shaft keys.
The third step is to connect the electric motor with Planetary reduction drive by natural means.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 outer flange of both must be parallel.If the concentricity is not consistent, the electric motor shaft will be broken or of Planetary reduction drive gear wear.
Furthermore, in the installation, usually do not use hammer and other blows, avoid the axial force or radial force too much harm to the bearing or equipment.Be sure to tighten the mounting bolt just before tightening the force bolt.Before installation, wipe away the anti-rust 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 overall flexibility of operation, preventing unnecessary wear and tear.
Before the motor and Planetary decrease drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, initial screw the assembly bolts at virtually any diagonal position, but do not screw restricted, then screw the set up bolts at the various other two diagonal positions, and finally screw the four installation bolts one at a time.Finally, tighten the force bolt.All tightening bolts will 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 equipment is equivalent to correct installation between of Planetary reduction travel and drive engine.The key is to ensure that the output shaft of Planetary reduction drive and the drive the main shaft concentricity.
