Planetary reduction travel in the use 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 caused by the friction, vibration and collision of the transmission gears. How to properly reduce and decrease the noise to make it more good requirements of environmental coverage is also a key research topic in the home and abroad.Reducing the apparatus transmission noise of Planetary reduction travel has become an important research subject in the industry. Many scholars at home and abroad regard the change of equipment tooth engagement stiffness in gear transmission as the primary factor of gear powerful load, vibration and sound.By modifying the form, the dynamic load and velocity fluctuation are minimized to reduce the noise.This technique has became more effective used.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 usually a kind of of Planetary reduction travel, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes 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 assisting axis.The planetary wheel, the sun wheel and the gear ring are in continuous meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, sunlight wheel and the planet wheel quite often engage, two external equipment meshing rotation direction is definitely opposite.Just as the sun is at the guts of the solar system, the solar wheel is named for its location.Gear band is the internal gear, it and the planet wheel often meshing, is the inner tooth and the external gear meshing, the rotation direction between your two is the same.The amount of planetary gear is determined by the look load of the Planetary reduction drive, usually three or four, the more the amount of bear the load is greater.
The above is the Planetary reduction drive equipment transmission structure of the primary content.
Planetary speed of Planetary reduction drive is normally a sort of speed of Planetary reduction drive, in that case, the planetary speed of Planetary reduction drive along the way of using the reason for the shaft break what?Let’s take a look.
1. The wrong type assortment causes insufficient end result torque Pa300of the Planetary lowering drive.
Some users in the version selection, mistakenly as long as the selected rated end result torque Planetary reduction drive to meet up the work requirements can be, in fact, it isn’t, one may be the rated output torque of the motor rated output torque times deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise sample to supply similar Planetary reduction travel rated result torque.The other is to consider the overload capacity of the drive motor and the maximum operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary decrease drive exceeds two times of its ranked output torque, and this kind of acceleration and deceleration is normally too frequent, that may eventually make Planetary reduction travel break the shaft.
Theoretically, the utmost operating torque required simply by an individual must be significantly 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 prevent the output shaft of Planetary reduction drive from being twisted off.The main reason is that, when 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 driving a car motor will still make it constantly boost the output force, which might cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque 2 times and so twist the output shaft of the Planetary reduction travel.

Listed below are the size and complementing tolerance of the positioning boss, insight shaft and Planetary lowering travel groove of the motor.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary lowering drive flange, modify the clamping ring of PCS program to align the side hole with the dustproof hole, insert the internal hexagon to tighten.From then on, take away the motor shaft keys.
The 3rd step is to hook up the electric motor with Planetary reduction drive by natural means.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 outer flange of both should be parallel.If the concentricity is not consistent, the motor shaft will be broken or of Planetary reduction drive gear wear.
In addition, in the installation, usually do not use hammer and other blows, prevent the axial force or radial force too much damage to the bearing or equipment.Make sure you tighten the mounting bolt prior to tightening the force bolt.Before installation, wipe aside 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 purpose is to ensure tight connection and flexibility of operation, and prevent unnecessary wear and tear.
Before the motor and Planetary lowering drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, primary screw the assembly bolts at any diagonal position, but do not screw tight, then screw the installation bolts at the various other two diagonal positions, and lastly screw the four unit 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.
Correct installation between of Planetary reduction drive and mechanical products is the same as correct installation between of Planetary reduction drive and drive electric motor.The main element is to ensure that the output shaft of Planetary reduction drive and the drive portion of the shaft concentricity.
