Connection mode between of Planetary reduction drive and servo electric motor: holding mode – output shaft of servo engine extends into of Planetary decrease drive, servo motor and Planetary reduction drive are linked by flange. There is a deformable hoop in Planetary decrease drive. By operating the locking screw on Planetary decrease travel, the hoop can tighten the axis of the servo motor (the author includes a 0.75KW servo motor with this connection). Hence for this connection setting, servo motors usually do not require keyway (of course, keyway can also be, but purchasing keyway servo motors requires 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 method uses exterior coupling, so it needs servo electric and keyway. External coupling can also use versatile coupling (flexible shaft) – very soft shaft drive electricity generally does not exceed 5.5KW, speed can reach 20000 rpm. A kind of
Generally speaking, the servo motors without brakes and keyways are the many used and the Ever-Power may be the largest. Therefore, to purchase the servo motors with brakes and keyways, the delivery period is for a longer time, about 4 weeks.
Planetary reduction travel in the utilization 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 decrease the noise to make it more based on the requirements of environmental security is also a key research topic at home and abroad.Reducing the gear transmission noise of Planetary reduction drive has become a crucial research subject matter in the industry. Many scholars in the home and abroad respect the change of gear tooth engagement stiffness in equipment transmission as the primary factor of gear powerful load, vibration and noise.By modifying the shape, the dynamic load and velocity fluctuation are minimized to reduce the noise.This technique has proved to be more effective in practice.But with this technique, the process needs to have shape modification equipment, nearly all small factories often can’t be implemented.
Planetary reduction drive can be a sort of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear carries a sun steering wheel, a planetary wheel, and a gear band, wherein the planetary steering wheel is supported by a set axis of the planetary framework, allowing the planetary steering wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the apparatus ring are in continuous meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, the sun 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 named for its location.Gear ring is the interior gear, it and the planet wheel often meshing, may be the internal tooth and the external gear meshing, the rotation direction between the two may be the same.The amount of planetary gear depends upon the look load of the Planetary reduction travel, usually three or four, the more the amount of bear the load is greater.
The above may be the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a kind of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive in the process of using the cause of the shaft break what?Let’s have a look.
1. The wrong type assortment causes insufficient end result torque of the Planetary reduction drive.
Some users in the style selection, mistakenly provided that the selected rated output torque Planetary reduction drive to meet up the work requirements can be, in fact, it isn’t, one is the rated result torque of the engine rated output torque circumstances deceleration ratio, the worthiness obtained in principle should be less than the product 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. In the process of acceleration and deceleration, the instantaneous torque borne by the productivity shaft of the Planetary decrease drive exceeds two times of its ranked output torque, and these kinds of acceleration and deceleration is certainly too frequent, that may eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required 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 primary 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 car 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 travel.

Product Description:
There are two main types in line with the output direction: straight type and right angle type; Planetary equipment systems are used to perform speed reduction because of huge torque. to predict equipment noise from a rear wheel drive programmed transmission.
There are usually three types based on the number of stages: one-stage deceleration (generally significantly less than 10:1), two-stage deceleration (generally higher 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 greater than 100:1);
According to the purpose: army and civilian;In line with the operating environment: regular environment, low temperature environment, clean space environment and vacuum environment;

With the Ever-Electricity mountain drive you gain additional very low gears which permit you proceed climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The first step is to confirm whether the electric motor and Planetary reduction drive are in good condition before installation, and strictly check whether the size of each part linked with the electric motor and Planetary reduction travel is matched. Here are the size and coordinating tolerance of the positioning boss, type shaft and Planetary lowering drive groove of the motor.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary lowering drive flange, modify the clamping ring of PCS program to align the medial 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 electric motor with Planetary reduction drive the natural way.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the motor must be constant when connected, and the external flange of the two must be parallel.If the concentricity is not consistent, the engine shaft will be broken or of Planetary lowering drive gear wear.
In addition, 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 gear.Be sure to tighten the mounting bolt prior to tightening the push 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 ensure tight connection and versatility of operation, preventing 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, initially screw the unit installation bolts at any diagonal position, but do not screw tight, then screw the installation bolts at the other two diagonal positions, and lastly screw the four assembly bolts one by one.Finally, tighten the force bolt.All tightening bolts shall be fixed and examined by the torque plate hand in line with the indicated torque data.
Right installation between of Planetary reduction drive and mechanical equipment is equivalent to right installation between of Planetary reduction travel and drive engine.The main element is to ensure that the output shaft of Planetary reduction travel and the drive section of the shaft concentricity.
