Planetary reduction drive in the utilization of the process you will have some noise, the emergence of the noise, how to deal with it?
The noise of Planetary reduction travel is mainly due to the friction, vibration and collision of the transmission gears. How to successfully reduce and reduce the noise to make it more based on the requirements of environmental security is also an integral research topic at home and abroad.Reducing the apparatus transmission sound of Planetary reduction drive has become a significant research issue in the market. Many scholars in the home and abroad regard the change of gear tooth engagement stiffness in gear transmission as the primary 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 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 a sort of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sun wheel, a planetary wheel, and a gear band, wherein the planetary steering wheel is supported by a fixed axis of the planetary framework, allowing the planetary wheel to rotate on the supporting axis.The planetary wheel, sunlight wheel and the apparatus ring are in frequent meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the planet wheel quite often engage, two external gear meshing rotation direction is definitely opposite.Just as the sun is at the guts of the solar system, the solar wheel is known as because of its location.Gear band is the interior gear, it and the earth wheel often meshing, may be the inner tooth and the external gear meshing, the rotation direction between your two may be the same.The quantity of planetary gear depends upon the design load of the Planetary reduction travel, usually 3 or 4, the more the amount of bear the strain is greater.
The above is the Planetary reduction drive equipment transmission structure of the primary content.
Planetary speed of Planetary reduction drive can be 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 variety causes insufficient productivity torque of the Planetary decrease drive.
Some users in the unit selection, mistakenly provided that the selected rated end result torque Planetary reduction travel to meet the work requirements could be, in fact, it is not, one is the rated productivity torque of the engine rated output torque instances deceleration ratio, the worthiness obtained in principle ought to be less than the product sample to supply similar Planetary reduction travel rated end result torque.The other is to consider the overload capacity of the drive engine and the maximum operating torque required in practice.
2. Along the way 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 sort of acceleration and deceleration is usually too frequent, that may eventually make Planetary lowering travel break the shaft.
Theoretically, the utmost operating torque required 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 comply with this criterion.This is not only to 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, 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 traveling motor will still make it constantly raise the output force, which may cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque 2 times and so twist the output shaft of the Planetary reduction travel.

The initial step is to confirm whether the engine and Planetary reduction travel are in good condition before installation, and strictly check if the size of every part linked with the motor and Planetary reduction travel is matched. Listed below are the size and complementing tolerance of the positioning boss, input shaft and Planetary reduction drive groove of the electric motor.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, modify the clamping band 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 connect the engine with Planetary reduction travel normally.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the engine must be constant when connected, and the external flange of the two must be parallel.If the concentricity is not consistent, the motor shaft will be broken or of Planetary lowering drive gear wear.
Furthermore, in the installation, usually do not use hammer and various other blows, avoid the axial force or radial force an excessive amount of damage to the bearing or gear.Be sure to tighten the mounting bolt just before tightening the drive bolt.Before installation, wipe aside the anti-rust 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 overall flexibility of operation, and prevent unnecessary wear and tear.
Prior to the motor and Planetary lowering drive are connected, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, 1st screw the unit installation bolts at any kind of diagonal position, but do not screw restricted, then screw the installation bolts at the different two diagonal positions, and lastly screw the four set up 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.
Right installation between of Planetary reduction travel and mechanical gear is equivalent to appropriate installation between of Planetary reduction drive and drive electric motor.The key is to ensure that the output shaft of Planetary reduction travel and the drive area of the shaft concentricity.
