Planetary reduction travel in the utilization 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 exactly to properly reduce and reduce the noise to make it more in line with the requirements of environmental security is also an integral research topic in the home and abroad.Reducing the gear transmission noise of Planetary reduction drive has become a significant research issue in the industry. Many scholars at home and abroad regard the change of gear tooth engagement stiffness in equipment transmission as the main factor of gear powerful load, vibration and noises.By modifying the shape, the dynamic load and velocity fluctuation are minimized to lessen the noise.This technique 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 can be a kind of of Planetary reduction drive, 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 wheel is supported by a fixed axis of the planetary body, allowing the planetary steering wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the apparatus ring are in continuous meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, the sun wheel and the planet wheel often engage, two external gear meshing rotation direction is normally opposite.Just as the sun is at the center of the solar program, the solar wheel is named because of its location.Gear band is the internal gear, it and the earth wheel often meshing, is the inner tooth and the external gear meshing, the rotation direction between your two may be the same.The number of planetary gear is determined by the design load of the Planetary reduction travel, usually three or four, the more the amount of bear the strain is greater.
The above is the Planetary reduction travel gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a kind of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive in the process of using the reason for the shaft break what?Let’s take a look.
1. The wrong type variety causes insufficient result 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 up the work requirements can be, in fact, it isn’t, one may be the rated end result torque of the motor rated output torque moments deceleration ratio, the value obtained in principle should be less than the merchandise sample to supply similar Planetary reduction drive rated result torque.The other is to consider the overload capacity of the drive motor and the utmost operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the output shaft of the Planetary decrease drive exceeds 2 times of its rated output torque, and such acceleration and deceleration is too frequent, that may eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required simply by an individual must be significantly less than 2 times the rated output torque of the Planetary reduction drive, especially in a few applications must strictly adhere to this criterion.This is simply not only to 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 travel and its load are stuck, the overload capacity of the traveling 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 2 times and so twist the output shaft of the Planetary reduction drive.

Step 2 2: unscrew the screw on the external dustproof hole of of Planetary reduction drive flange, modify the clamping band of PCS system to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, take away the motor shaft keys.
The third step is to connect the electric motor with Planetary reduction drive normally.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the motor must be regular when connected, and the external flange of both should be parallel.If the concentricity is not consistent, the engine shaft will be broken or of Planetary decrease drive gear wear.
Furthermore, in the installation, do not use hammer and various other blows, avoid the axial force or radial force an excessive amount of harm to the bearing or gear.Make sure you tighten the mounting bolt just before tightening the push 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 purpose is to make sure tight connection and overall flexibility of operation, and prevent unnecessary wear and tear.
Prior to the motor and Planetary reduction drive are linked, the motor shaft keyway ought to be perpendicular to the tightening bolt.To ensure a uniform force, 1st screw the set up bolts at virtually any diagonal position, but do not screw restricted, then screw the set up bolts at the different two diagonal positions, and finally screw the four assembly bolts one at a time.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.
