Planetary reduction travel in the use of the process you will have 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 properly reduce and decrease the noise to make it more in line with the requirements of environmental safeguard is also an integral research topic at home and abroad.Reducing the gear transmission sound of Planetary reduction travel has become an important research matter in the industry. Many scholars at home and abroad respect the change of equipment tooth engagement stiffness in gear transmission as the main factor of gear powerful load, vibration and sound.By modifying the shape, the powerful load and velocity fluctuation are minimized to reduce the noise.This method has proved to be more effective in practice.But with this method, the process needs to have shape modification equipment, nearly all small factories often can’t be implemented.
Planetary reduction drive is normally a sort of of Planetary reduction travel, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun 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 wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in constant meshing state.
Located in the center of the planetary gear transmission mechanism may be the sun wheel, the sun wheel and the earth wheel quite often engage, two external gear meshing rotation direction is definitely opposite.Just as sunlight is at the center of the solar program, the solar wheel is named because of its location.Gear band is the internal gear, it and the earth wheel often meshing, is the inner tooth and the outer gear meshing, the rotation direction between the two may be the same.The number of planetary gear depends upon the look load of the Planetary reduction drive, usually 3 or 4, the more the number of bear the load is greater.
The above is the Planetary reduction travel equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is a sort 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 collection causes insufficient outcome torque of the Planetary reduction drive.
Some users in the model selection, mistakenly as long as the selected rated result torque Planetary reduction drive to meet the work requirements can be, in fact, it is not, one may be the rated output torque of the motor rated output torque instances deceleration ratio, the value obtained in principle should be less than the product sample to supply similar Planetary reduction drive rated outcome torque.The other is to consider the overload capacity of the drive electric motor and the maximum 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 ranked output torque, and this kind of acceleration and deceleration is usually too frequent, which will eventually make Planetary reduction travel break the shaft.
Theoretically, the utmost 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 simply 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, if there is a problem in equipment installation, the output shaft of the Planetary reduction drive and its own load are stuck, the overload capacity of the driving a car 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 drive.
Precision planetary reduction travel
Product Description:
There are two main types in line with the output direction: direct type and correct angle type; Planetary gear systems are used to execute speed reduction because of huge torque. to predict equipment noise from a rear wheel drive automatic transmission.
There are generally 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 significantly 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);
In line with the purpose: army and civilian;According to the operating environment: common environment, low temp environment, clean area environment and vacuum environment;

Here are the size and matching tolerance of the positioning boss, suggestions shaft and Planetary reduction travel groove of the motor.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary decrease 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, remove the motor shaft keys.
The third step is to connect the engine with Planetary reduction drive by natural means.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the motor must be constant when connected, and the external flange of the two should be parallel.If the concentricity is not consistent, the engine shaft will be broken or of Planetary reduction drive gear wear.
In addition, in the installation, do not use hammer and other blows, avoid the axial force or radial force an excessive amount of harm to the bearing or equipment.Make sure you tighten the installation bolt just before tightening the power bolt.Before installation, wipe away 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, preventing unnecessary wear and tear.
Prior to the motor and Planetary decrease drive are connected, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, first screw the unit installation bolts at virtually any diagonal position, but do not screw tight, then screw the unit installation bolts at the different two diagonal positions, and lastly screw the four set up 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.
Appropriate installation between of Planetary reduction travel and mechanical tools is equivalent to correct installation between of Planetary reduction travel and drive electric motor.The main element is to ensure that the output shaft of Planetary reduction drive and the drive area of the shaft concentricity.
