Planetary reduction drive in the application of the process you will see some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction drive is mainly due to the friction, vibration and collision of the transmission gears. How to properly reduce and decrease the noise to create it more in line with the requirements of environmental proper protection is also a key research topic at home and abroad.Reducing the gear transmission noise of Planetary reduction drive has become a crucial research topic in the industry. Many scholars at home and abroad regard the change of equipment tooth engagement stiffness in equipment transmission as the primary factor of gear dynamic load, vibration and noise.By modifying the shape, the powerful load and velocity fluctuation are minimized to lessen the noise.This method has proved to be more effective in practice.But with this method, the process will need shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive is normally a kind of of Planetary reduction drive, 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 band, wherein the planetary wheel is supported by a set axis of the planetary framework, allowing the planetary wheel to rotate on the supporting axis.The planetary wheel, sunlight wheel and the gear ring are in constant meshing state.
Located in the guts of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the planet wheel quite often engage, two external equipment meshing rotation direction is definitely opposite.Just as sunlight is at the guts of the solar system, the solar wheel is known as for its location.Gear band is the inner gear, it and the planet wheel often meshing, is the inner tooth and the external gear meshing, the rotation direction between the two is the same.The amount of planetary gear depends upon the look load of the Planetary reduction travel, usually 3 or 4, the more the quantity of bear the load is greater.
The above is the Planetary reduction travel equipment transmission structure of the key content.
Planetary speed of Planetary reduction drive is usually a sort of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive along the way of using the cause of the shaft break what?Let’s take a look.
1. The wrong type collection causes insufficient output torque of the Planetary lowering drive.
Some users in the unit selection, mistakenly so long as the selected rated result torque Planetary reduction drive to meet the work requirements can be, in fact, it isn’t, one is the rated outcome torque of the motor rated output torque circumstances deceleration ratio, the value obtained in principle should be less than the product sample to provide similar Planetary reduction travel rated result torque.The other is to consider the overload capacity of the drive electric motor and the utmost operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the outcome shaft of the Planetary decrease drive exceeds 2 times of its ranked output torque, and these kinds of acceleration and deceleration is definitely too frequent, that may eventually make Planetary reduction travel break the shaft.
Theoretically, the maximum 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 comply with 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 main 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 travelling motor will still make it constantly boost the output force, which might cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque two times and thus twist the output shaft of the Planetary reduction drive.

Listed below are the size and matching tolerance of the positioning boss, input shaft and Planetary lowering drive groove of the engine.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary lowering drive flange, change the clamping band of PCS program 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 third step is to connect the electric motor with Planetary reduction drive the natural way.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the motor must be regular 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 lowering drive gear wear.
In addition, 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 mounting bolt prior to tightening the power bolt.Before installation, wipe apart 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, and prevent unnecessary deterioration.
Before the motor and Planetary decrease drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, primary screw the set up bolts at virtually any diagonal position, but usually do not screw tight, then screw the installation bolts at the different two diagonal positions, and finally screw the four unit installation bolts one at a time.Finally, tighten the force bolt.All tightening bolts shall be fixed and checked by the torque plate hand based on the indicated torque data.
