Planetary reduction drive in the use 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 efficiently reduce and reduce the noise to make it more based on the requirements of environmental coverage is also a key research topic at home and overseas.Reducing the gear transmission sound of Planetary reduction drive has become a significant research topic in the market. 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 noise.By modifying the form, the powerful load and velocity fluctuation are minimized to lessen the noise.This technique has proved to be more effective in practice.But with this technique, the process will need shape modification equipment, nearly all 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 take a look.
A planetary gear carries a sun steering wheel, a planetary steering wheel, and a gear ring, wherein the planetary wheel is supported by a fixed axis of the planetary frame, allowing the planetary wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in regular meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the planet wheel often engage, two external equipment meshing rotation direction is usually opposite.Just as sunlight is at the guts of the solar system, the solar wheel is named because of its location.Gear ring is the inner gear, it and the planet wheel often meshing, may be the internal tooth and the outer gear meshing, the rotation direction between the two is the same.The amount of planetary gear is determined by the design load of the Planetary reduction travel, usually 3 or 4, the more the amount of bear the load is greater.
The above is the Planetary reduction travel gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is usually a sort of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive along the way of using the reason for the shaft break what?Let’s have a look.
1. The wrong type collection causes insufficient productivity torque of the Planetary reduction drive.
Some users in the unit selection, mistakenly so long as the selected rated productivity 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 situations deceleration ratio, the value obtained in principle should be less than the product sample to supply similar Planetary reduction travel rated outcome torque.The other is to consider the overload capacity of the drive engine and the utmost operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary lowering drive exceeds 2 times of its rated output torque, and these kinds of acceleration and deceleration can be too frequent, that may eventually make Planetary decrease travel break the shaft.
Theoretically, the utmost operating torque required 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 simply 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 load are stuck, the overload capacity of the driving a vehicle motor will still make it constantly increase 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 therefore twist the output shaft of the Planetary reduction drive.

With the Ever-Ability mountain drive you get additional suprisingly low gears which permit you choose climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to verify whether the motor and Planetary reduction travel are in good shape before installation, and strictly check if the size of every part linked with the electric motor and Planetary reduction drive is matched. Listed below are the size and coordinating tolerance of the positioning boss, input shaft and Planetary lowering travel groove of the motor.
Step two 2: unscrew the screw on the external dustproof hole of of Planetary reduction drive flange, change the clamping band of PCS program to align the medial side hole with the dustproof hole, insert the internal hexagon to tighten.From then on, remove the motor shaft keys.
The third step is to hook up the engine with Planetary reduction travel the natural way.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the motor must be steady when connected, and the external flange of both must be parallel.If the concentricity is not consistent, the engine shaft will be broken or of Planetary lowering drive gear wear.
In addition, in the installation, do not use hammer and other blows, prevent the axial force or radial force an excessive amount of damage to the bearing or gear.Be sure to tighten the mounting bolt ahead of 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 versatility of operation, and stop unnecessary wear and tear.
Before the motor and Planetary reduction drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, primary screw the installation bolts at any kind of diagonal position, but usually do not screw restricted, then screw the installation bolts at the other two diagonal positions, and finally screw the four installation bolts one at a time.Finally, tighten the force bolt.All tightening bolts will be fixed and examined by the torque plate hand based on the indicated torque data.
Correct installation between of Planetary reduction drive and mechanical tools is the same as correct 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 portion of the shaft concentricity.
