Connection setting between of Planetary decrease drive and servo electric motor: holding mode – outcome shaft of servo electric motor extends into of Planetary decrease drive, servo motor and Planetary reduction drive are connected by flange. You will find a deformable hoop in Planetary decrease drive. By functioning 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 electric motor with this connection). And so for this connection method, servo motors do not require keyway (of lessons, keyway can also be, but ordering keyway servo motors needs Money and delivery time are longer yo @ @). Some sort of
Connecting mode of_of Planetary decrease drive and servo motor: Connecting through exterior coupling. This connection method uses exterior coupling, so it needs servo electrical and keyway. External coupling may also use flexible coupling (flexible shaft) – soft shaft drive power generally does not exceed 5.5KW, speed may reach 20000 rpm. Some sort of
Generally speaking, the servo motors without brakes and keyways are the most used and the Ever-Power may be the largest. For that reason, to order the servo motors with brakes and keyways, the delivery period is longer, about 4 weeks.
Planetary reduction travel in the application of the process you will see some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction drive is mainly due to the friction, vibration and collision of the transmission gears. How exactly to properly reduce and decrease the noise to create it more good requirements of environmental coverage is also an integral research topic at home and overseas.Reducing the apparatus transmission noises of Planetary reduction travel has become a crucial research issue in the industry. Many scholars in the home and abroad regard the change of gear tooth engagement stiffness in equipment transmission as the key factor of gear dynamic load, vibration and noises.By modifying the form, the dynamic 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 a kind of of Planetary reduction drive, what’s 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 framework, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, the sun wheel and the gear ring are in regular meshing state.
Located in the guts of the planetary equipment transmission mechanism is the sun wheel, the sun wheel and the earth wheel often engage, two external equipment meshing rotation direction is usually opposite.Just as sunlight is at the center of the solar system, the solar wheel is known as because of its location.Gear band is the inner gear, it and the planet wheel often meshing, is the inner tooth and the outer gear meshing, the rotation direction between your two may be 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 load is greater.
The above is the Planetary reduction drive gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is definitely a kind of speed of Planetary reduction drive, then, the planetary speed of Planetary reduction drive in the process of using the cause of the shaft break what?Let’s take a look.
1. The wrong type assortment causes insufficient end result torque of the Planetary reduction drive.
Some users in the model selection, mistakenly given that the selected rated outcome torque Planetary reduction drive to meet up the work requirements could be, in fact, it is not, one may be the rated output torque of the electric motor rated output torque circumstances deceleration ratio, the value obtained in principle should be less than the product sample to provide similar Planetary reduction drive rated result torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the outcome shaft of the Planetary lowering drive exceeds two times of its rated output torque, and these kinds of acceleration and deceleration is certainly too frequent, that will eventually make Planetary reduction 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 a few applications must strictly adhere to this criterion.This is not only to 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, 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 traveling motor will still make it constantly improve 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 therefore twist the output shaft of the Planetary reduction drive.
Precision planetary reduction drive
Product Description:
There are two main types in line with the output direction: straight type and proper angle type; Planetary equipment systems are used to perform speed reduction due to significant torque. to predict gear noise from a back wheel drive programmed transmission.
There are usually three types according to the number of stages: one-stage deceleration (generally significantly 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 (significant reduction ratio is 100) :1, the overall division principle is greater than 100:1);
According to the purpose: army and civilian;According to the operating environment: regular environment, low temperatures environment, clean space environment and vacuum environment;

With the Ever-Electric power mountain drive you get additional suprisingly low gears which enable you get climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to verify whether the electric motor and Planetary reduction drive are in good shape before installation, and strictly check whether the size of every part linked with the engine and Planetary reduction drive is matched. Listed below are the size and complementing tolerance of the positioning boss, suggestions shaft and Planetary lowering drive groove of the motor.
Step two 2: unscrew the screw on the external dustproof hole of of Planetary lowering drive flange, adapt the clamping band of PCS program 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 connect the electric motor with Planetary reduction travel by natural means.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the motor must be constant when connected, and the outer flange of both should be parallel.If the concentricity isn’t consistent, the motor shaft will be broken or of Planetary decrease drive gear wear.
Furthermore, in the installation, usually do not use hammer and different blows, avoid the axial force or radial force an excessive amount of damage to the bearing or gear.Make sure you tighten the mounting bolt before tightening the drive bolt.Before installation, wipe away 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 ensure tight connection and versatility of operation, preventing unnecessary deterioration.
Before the motor and Planetary lowering drive are connected, the motor shaft keyway ought to be perpendicular to the tightening bolt.To ensure a uniform force, first screw the installation bolts at any diagonal position, but usually do not screw restricted, then screw the installation bolts at the other two diagonal positions, and finally 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 the same as accurate installation between of Planetary reduction travel and drive electric motor.The main element is to make certain that the output shaft of Planetary reduction travel and the drive portion of the shaft concentricity.
