Planetary reduction drive in the utilization of the process you will see some noise, the emergence of the noise, how 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 reduce the noise to create it more based on the requirements of environmental proper protection is also a key research topic in the home and overseas.Reducing the gear transmission noises of Planetary reduction travel has become a crucial research subject in the market. Many scholars at home and abroad regard the change of gear tooth engagement stiffness in equipment transmission as the main 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 used.But with this method, the process needs to have shape modification equipment, nearly all small factories often can not be implemented.
Planetary reduction drive can be a kind of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun steering wheel, a planetary steering wheel, and a gear ring, wherein the planetary wheel is supported by a set axis of the planetary frame, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the apparatus ring are in constant meshing state.
Located in the center of the planetary equipment transmission mechanism may be the sun wheel, sunlight wheel and the planet wheel quite often engage, two external gear meshing rotation direction is certainly opposite.Just as the sun is at the center of the solar program, the solar wheel is known as because of its location.Gear ring is the inner gear, it and the planet wheel often meshing, is the internal tooth and the outer gear meshing, the rotation direction between your two is the same.The amount of planetary gear depends on 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 equipment transmission structure of the primary 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 take a look.
1. The wrong type variety causes insufficient result torque of the Planetary reduction drive.
Some users in the model selection, mistakenly given that the selected rated result torque Planetary reduction travel to meet the work requirements can be, in fact, it isn’t, one is the rated productivity torque of the motor rated output torque moments deceleration ratio, the value obtained in principle should be less than the product sample to supply 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 used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the output shaft of the Planetary reduction drive exceeds 2 times of its ranked output torque, and this sort of acceleration and deceleration is too frequent, which will eventually make Planetary reduction travel break the shaft.
Theoretically, the utmost operating torque required by an individual 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 simply not and then protect the Planetary reduction drive, but also to avoid the output shaft of Planetary reduction drive from being twisted off.The primary reason is that, if 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 travelling motor will still make it constantly increase 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 travel
Product Description:
There are two main types according to the output direction: straight type and proper angle type; Planetary gear systems are used to perform speed reduction because of huge torque. to predict equipment noise from a backside wheel drive computerized transmission.
There are generally three types based on the number of stages: one-stage deceleration (generally less than 10:1), two-stage deceleration (generally greater than 10:1 and significantly less than or equal to 100:1), and three-stage deceleration (large reduction ratio is 100) :1, the overall division principle is greater than 100:1);
Based on the purpose: military and civilian;Based on the operating environment: typical environment, low heat environment, clean place environment and vacuum environment;

With the Ever-Vitality mountain drive you get additional very low gears which allow you go climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to confirm whether the engine and Planetary reduction travel are in good condition before installation, and strictly check if the size of each part linked with the engine and Planetary reduction drive is matched. Here are the size and coordinating tolerance of the positioning boss, input shaft and Planetary reduction 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 system to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.After that, take away the motor shaft keys.
The 3rd step is to hook up the electric motor with Planetary reduction travel by natural means.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be constant when connected, and the outer flange of both should be parallel.If the concentricity is not consistent, the electric motor shaft will be broken or of Planetary lowering drive gear wear.
In addition, in the installation, do not use hammer and various other blows, avoid the axial force or radial force too much damage to the bearing or equipment.Be sure to tighten the mounting bolt ahead of tightening the pressure bolt.Before installation, wipe apart the anti-rust oil of motor input shaft, positioning boss and connecting portion of of Planetary reduction drive with gasoline or zinc-sodium water.Its purpose is to make sure tight connection and overall flexibility of operation, preventing unnecessary wear and tear.
Prior to the motor and Planetary reduction drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, 1st screw the set up bolts at virtually any diagonal position, but do not screw tight, then screw the installation bolts at the additional 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 according to the indicated torque data.
Right installation between of Planetary reduction travel and mechanical products is the same as accurate installation between of Planetary reduction travel and drive electric motor.The key is to make certain that the output shaft of Planetary reduction travel and the drive the main shaft concentricity.
