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 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 protection is also an integral research topic in the home and overseas.Reducing the gear transmission noises of Planetary reduction drive has become an essential research subject matter in the market. 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 noises.By modifying the form, the powerful load and velocity fluctuation are minimized to reduce the noise.This method has became 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 is usually 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 steering wheel, a planetary wheel, and a gear ring, wherein the planetary steering wheel is supported by a fixed axis of the planetary framework, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in regular meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the planet wheel generally engage, two external equipment meshing rotation direction is normally opposite.Just as sunlight is at the center of the solar system, the solar wheel is named for its location.Gear ring is the interior gear, it and the earth wheel often meshing, may be the internal tooth and the outer gear meshing, the rotation direction between your two is the same.The number of planetary gear depends on the design load of the Planetary reduction travel, usually three or four, the more the quantity of bear the load is greater.
The above is the Planetary reduction drive gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is 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 variety causes insufficient result torque of the Planetary lowering 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 could be, in fact, it is not, one is the rated result torque of the motor rated output torque instances deceleration ratio, the value obtained in principle ought to be less than the product sample to supply similar Planetary reduction travel 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 outcome shaft of the Planetary lowering drive exceeds 2 times of its rated output torque, and these kinds of acceleration and deceleration is normally too frequent, which will eventually make Planetary decrease drive break the shaft.
Theoretically, the utmost operating torque required simply by the user must be less than two times the rated output torque of the Planetary reduction drive, especially in some 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, 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 generating motor will still make it constantly raise the output force, which may cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque 2 times and thus twist the output shaft of the Planetary reduction travel.
Precision planetary reduction drive
Product Description:
There are two main types based on the output direction: direct type and correct angle type; Planetary gear systems are used to execute speed reduction because of large torque. to predict equipment noise from a rear wheel drive automatic 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 higher than 10:1 and less than or equal 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: army and civilian;Based on the operating environment: normal environment, low temperatures environment, clean room environment and vacuum environment;

With the Ever-Power mountain drive you get additional suprisingly low gears which enable you move climb the the majority of extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The first step is to verify whether the motor and Planetary reduction drive are in good condition before installation, and strictly check if the size of every part linked with the electric motor and Planetary reduction drive is matched. Here are the size and matching tolerance of the positioning boss, type shaft and Planetary lowering travel groove of the electric motor.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, modify the clamping ring of PCS system to align the side hole with the dustproof hole, insert the interior hexagon to tighten.From then on, take away the motor shaft keys.
The 3rd step is to connect the engine with Planetary reduction drive naturally.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the electric motor must be consistent when connected, and the external flange of both must be parallel.If the concentricity isn’t consistent, the engine shaft will be broken or of Planetary lowering drive gear wear.
In addition, in the installation, do not use hammer and different blows, prevent the axial force or radial force too much harm to the bearing or gear.Make sure you tighten the mounting bolt just before tightening the force bolt.Before installation, wipe aside the anti-corrosion 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 flexibility of operation, preventing unnecessary wear and tear.
Before the motor and Planetary reduction drive are connected, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure 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 additional two diagonal positions, and lastly screw the four installation bolts one by one.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 travel and mechanical apparatus is equivalent to appropriate 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 part of the shaft concentricity.
