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 effectively reduce and decrease the noise to create it more in line with the requirements of environmental coverage is also a key research topic in the home and overseas.Reducing the gear transmission noise of Planetary reduction drive has become an important research matter in the industry. Many scholars in the home and abroad regard the change of equipment tooth engagement stiffness in equipment transmission as the key factor of gear powerful load, vibration and noises.By modifying the shape, the powerful 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 will need shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive is normally a sort of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun wheel, a planetary steering wheel, and a gear ring, wherein the planetary wheel is supported by a fixed axis of the planetary body, allowing the planetary wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in continuous meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the earth wheel frequently 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 for its location.Gear band is the inner gear, it and the planet wheel often meshing, may be the interior tooth and the external gear meshing, the rotation direction between the two is the same.The amount of planetary gear depends on the design load of the Planetary reduction travel, usually three or four, the more the amount 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, in that case, the planetary speed of Planetary reduction drive along the way of using the cause of the shaft break what?Let’s have a look.
1. The wrong type selection causes insufficient outcome torque of the Planetary lowering drive.
Some users in the unit selection, mistakenly so long as the selected rated productivity torque Planetary reduction travel to meet up the work requirements could be, in fact, it is not, one is the rated productivity torque of the engine rated output torque situations deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise sample to provide similar Planetary reduction drive rated end result torque.The other is to consider the overload capacity of the drive 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 two times of its rated output torque, and this kind of acceleration and deceleration is usually too frequent, that will eventually make Planetary decrease travel break the shaft.
Theoretically, the maximum 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 adhere to this criterion.This is not only to protect the Planetary reduction drive, but also to avoid 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 load are stuck, the overload capacity of the driving a vehicle motor will still make it constantly increase the output force, which might cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and so twist the output shaft of the Planetary reduction travel.

Step two 2: unscrew the screw on the external dustproof hole of of Planetary decrease drive flange, adjust the clamping ring of PCS program to align the side hole with the dustproof hole, insert the internal hexagon to tighten.After that, take away the motor shaft keys.
The 3rd step is to connect 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 motor must be constant when connected, and the outer flange of the two must be parallel.If the concentricity is not consistent, the engine shaft will be broken or of Planetary lowering drive gear wear.
Furthermore, in the installation, do not use hammer and additional blows, avoid the axial force or radial force too much harm to the bearing or gear.Make sure to tighten the mounting bolt prior to tightening the power bolt.Before installation, wipe apart the anti-corrosion oil of motor input shaft, positioning boss and connecting part 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 deterioration.
Prior to 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, first screw the installation bolts at any diagonal position, but do not screw limited, then screw the installation bolts at the various other two diagonal positions, and finally screw the four set up bolts one by one.Finally, tighten the force bolt.All tightening bolts shall be fixed and checked by the torque plate hand according to the indicated torque data.
