Planetary reduction drive in the application of the process there will be some noise, the emergence of the noise, how exactly 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 effectively reduce and decrease the noise to create it more based on the requirements of environmental security is also an integral research topic in the home and overseas.Reducing the gear transmission noise of Planetary reduction travel has become an essential research issue in the market. Many scholars at home and abroad respect the change of equipment tooth engagement stiffness in gear transmission as the key factor of gear powerful load, vibration and noise.By modifying the shape, the powerful load and velocity fluctuation are minimized to reduce the noise.This technique has became more effective in practice.But with this method, the process will need shape modification equipment, the majority of small factories often can not be implemented.
Planetary reduction drive is a sort of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun steering wheel, a planetary wheel, and a gear band, 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, sunlight wheel and the apparatus ring are in constant meshing state.
Located in the center of the planetary gear transmission mechanism may be the sun wheel, the sun wheel and the earth wheel generally engage, two external equipment meshing rotation direction is opposite.Just as the sun is at the guts of the solar program, the solar wheel is known as for its location.Gear ring is the inner gear, it and the planet wheel often meshing, is the interior tooth and the outer gear meshing, the rotation direction between the two is the same.The quantity of planetary gear is determined by the design load of the Planetary reduction drive, usually three or four, the more the quantity of bear the load is greater.
The above is the Planetary reduction travel equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is normally a kind of speed of Planetary reduction drive, then, the planetary speed of Planetary reduction drive in the process of using the cause of the shaft break what?Let’s take a look.
1. The wrong type selection causes insufficient output torque of the Planetary lowering drive.
Some users in the version selection, mistakenly so long as the selected rated outcome torque Planetary reduction travel to meet the work requirements could be, in fact, it is not, one may be the rated output torque of the engine rated output torque occasions deceleration ratio, the value obtained in principle should be less than the product sample to provide similar Planetary reduction travel rated end result torque.The other is to consider the overload capacity of the drive engine and the utmost operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary reduction drive exceeds two times of its ranked output torque, and this sort 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 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 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, if there is a problem in equipment installation, the output shaft of the Planetary reduction drive and its own load are stuck, the overload capacity of the traveling motor will still make it constantly increase the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque 2 times and thus twist the output shaft of the Planetary reduction travel.

With the Ever-Electricity mountain drive you gain additional very low gears which permit you go climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The first step is to confirm whether the engine and Planetary reduction travel are in good condition before installation, and strictly check whether the size of each part connected with the electric motor and Planetary reduction drive is matched. Listed below are the size and complementing tolerance of the positioning boss, insight shaft and Planetary reduction travel groove of the engine.
Step two 2: unscrew the screw on the external dustproof hole of of Planetary lowering drive flange, adapt the clamping band of PCS system to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.After that, remove the motor shaft keys.
The 3rd step is to hook up the electric motor with Planetary reduction travel naturally.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 must be parallel.If the concentricity isn’t consistent, the engine shaft will be broken or of Planetary lowering drive gear wear.
In addition, in the installation, usually do not use hammer and different blows, avoid the axial force or radial force too much harm to the bearing or gear.Be sure to tighten the installation bolt prior to tightening the drive bolt.Before installation, wipe aside 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 goal is to make sure tight connection and versatility of operation, preventing unnecessary deterioration.
Before the motor and Planetary lowering drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, 1st screw the unit installation bolts at virtually 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 installation bolts one by one.Finally, tighten the force bolt.All tightening bolts will be fixed and checked by the torque plate hand according to the indicated torque data.
Right installation between of Planetary reduction drive and mechanical apparatus is the same as correct installation between of Planetary reduction drive and drive motor.The main element is to make certain that the output shaft of Planetary reduction travel and the drive area of the shaft concentricity.
