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 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 safety is also an integral research topic at home and overseas.Reducing the apparatus transmission noise of Planetary reduction travel has become an important research subject matter in the market. Many scholars at home and abroad regard the change of equipment tooth engagement stiffness in gear transmission as the key factor of gear dynamic load, vibration and sound.By modifying the shape, the powerful load and velocity fluctuation are minimized to lessen the noise.This technique has became more effective in practice.But with this method, the process needs to have shape modification equipment, nearly all 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 carries a sun wheel, a planetary wheel, and a gear ring, wherein the planetary steering wheel is supported by a set axis of the planetary body, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in constant meshing state.
Located in the guts of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the earth wheel often engage, two external equipment meshing rotation direction can be opposite.Just as sunlight is at the center of the solar system, the solar wheel is known as for its location.Gear ring is the interior gear, it and the planet wheel often meshing, may be the inner tooth and the external gear meshing, the rotation direction between the two may be the same.The quantity of planetary gear will depend on the design load of the Planetary reduction travel, usually three or four, the more the quantity of bear the load is greater.
The above is the Planetary reduction drive gear transmission structure of the key 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 reason for the shaft break what?Let’s have a look.
1. The wrong type assortment causes insufficient result torque of the Planetary lowering drive.
Some users in the model selection, mistakenly so long as the selected rated end result torque Planetary reduction drive to meet up the work requirements could be, in fact, it isn’t, one may be the rated productivity torque of the engine rated output torque situations deceleration ratio, the worthiness obtained in principle should be less than the merchandise sample to supply similar Planetary reduction drive rated productivity torque.The other is to consider the overload capacity of the drive electric motor and the utmost operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary decrease drive exceeds two times of its ranked output torque, and such acceleration and deceleration is normally too frequent, that will eventually make Planetary reduction drive break the shaft.
Theoretically, the utmost 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 some applications must strictly adhere to 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 primary reason is that, when 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 travelling motor will still make it constantly improve the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and thus twist the output shaft of the Planetary reduction drive.

Product Description:
There are two main types based on the output direction: right type and right angle type; Planetary gear systems are used to perform speed reduction due to huge torque. to predict gear noise from a backside wheel drive automated transmission.
There are usually three types according to the number of stages: one-stage deceleration (generally less than 10:1), two-stage deceleration (generally higher than 10:1 and significantly less than or add up to 100:1), and three-stage deceleration (large reduction ratio is 100) :1, the general division principle is greater than 100:1);
According to the purpose: military and civilian;In line with the operating environment: typical environment, low heat range environment, clean area environment and vacuum environment;

Here are the size and matching tolerance of the positioning boss, input shaft and Planetary lowering drive groove of the electric motor.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary lowering drive flange, adjust the clamping band of PCS system to align the side hole with the dustproof hole, insert the inner hexagon to tighten.After that, remove the motor shaft keys.
The third step is to connect the electric motor with Planetary reduction drive by natural means.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the electric motor must be regular when connected, and the outer flange of the two should be parallel.If the concentricity isn’t consistent, the electric motor shaft will be broken or of Planetary reduction drive gear wear.
In addition, in the installation, usually do not use hammer and different blows, prevent the axial force or radial force an excessive amount of damage to the bearing or equipment.Make sure you tighten the mounting bolt just before tightening the power 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 purpose is to ensure tight connection and overall flexibility of operation, and prevent unnecessary wear and tear.
Before the motor and Planetary decrease 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 virtually any diagonal position, but do not screw limited, then screw the assembly bolts at the additional 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 examined by the torque plate hand according to the indicated torque data.
Correct installation between of Planetary reduction travel and mechanical equipment is equivalent to appropriate installation between of Planetary reduction drive and drive engine.The key is to ensure that the output shaft of Planetary reduction travel and the drive section of the shaft concentricity.
