Planetary reduction travel in the consumption of the process there will be 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 effectively reduce and reduce the noise to create it more in line with the requirements of environmental safety is also a key research topic at home and overseas.Reducing the gear transmission noise of Planetary reduction travel has become an important research theme in the market. Many scholars in the home and abroad regard the change of equipment tooth engagement stiffness in equipment transmission as the key factor of gear dynamic load, vibration and noise.By modifying the form, the dynamic load and velocity fluctuation are minimized to lessen the noise.This technique has proved to be more effective used.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 kind of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear carries a sun wheel, a planetary wheel, and a gear ring, wherein the planetary wheel is supported by a fixed axis of the planetary frame, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the apparatus ring are in constant meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, the sun wheel and the planet wheel frequently engage, two external gear meshing rotation direction is usually opposite.Just as sunlight is at the guts of the solar system, the solar wheel is named for its location.Gear band is the interior gear, it and the earth wheel often meshing, is the internal tooth and the outer gear meshing, the rotation direction between the two may be the same.The quantity of planetary gear will depend on the design 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 travel gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is normally a sort 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 have a look.
1. The wrong type assortment causes insufficient productivity torque of the Planetary decrease drive.
Some users in the style selection, mistakenly as long as the selected rated productivity torque Planetary reduction drive to meet the work requirements could be, in fact, it is not, one is the rated output torque of the motor rated output torque circumstances deceleration ratio, the worthiness obtained in principle should be less than the merchandise sample to supply similar Planetary reduction drive rated outcome torque.The other is to consider the overload capacity of the drive motor and the utmost operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the output shaft of the Planetary reduction drive exceeds two times of its rated output torque, and this kind of acceleration and deceleration is certainly too frequent, that may eventually make Planetary decrease travel 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 a few applications must strictly adhere to this criterion.This is not and then 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 travel and its own load are stuck, the overload capacity of the driving 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 according to the output direction: straight type and proper angle type; Planetary gear systems are used to execute speed reduction due to huge torque. to predict gear noise from a rear wheel drive programmed transmission.
There are generally three types in line with 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 (huge reduction ratio is 100) :1, the general division principle is higher than 100:1);
In line with the purpose: army and civilian;Based on the operating environment: standard environment, low heat range environment, clean area environment and vacuum environment;
Our speed of Planetary reduction travel planetary gear for heavy-duty applications, including; conveyers, cranes, crawlers, and excavators. With the Ever-Power mountain drive you gain additional very low gears which allow you go climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to confirm whether the engine and Planetary reduction drive are in good shape before installation, and strictly check if the size of each part connected with the electric motor and Planetary reduction drive is matched. Listed below are the size and matching tolerance of the positioning boss, insight shaft and Planetary decrease travel groove of the electric motor.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary reduction drive flange, adapt the clamping ring of PCS system to align the medial side hole with the dustproof hole, insert the inner 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 the two must be parallel.If the concentricity isn’t consistent, the electric motor shaft will be broken or of Planetary lowering drive gear wear.
Furthermore, in the installation, do not use hammer and additional blows, prevent 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 induce bolt.Before installation, wipe away 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 goal is to ensure tight connection and overall flexibility of operation, and prevent unnecessary wear and tear.
Prior to the motor and Planetary decrease drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, first screw the unit installation bolts at virtually any diagonal position, but usually do not screw restricted, then screw the assembly 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 shall be fixed and checked by the torque plate hand based on the indicated torque data.
Accurate installation between of Planetary reduction drive and mechanical equipment is the same as appropriate installation between of Planetary reduction travel and drive motor.The key is to make certain that the output shaft of Planetary reduction drive and the drive section of the shaft concentricity.
