Planetary reduction drive in the use of the process you will have some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction drive is mainly due to the friction, vibration and collision of the transmission gears. How exactly to properly reduce and reduce the noise to create it more based on the requirements of environmental safeguard is also an integral research topic at home and abroad.Reducing the gear transmission noise of Planetary reduction drive has become an important research matter in the market. Many scholars at home and abroad respect the change of equipment tooth engagement stiffness in equipment transmission as the main factor of gear powerful load, vibration and sound.By modifying the shape, the dynamic load and velocity fluctuation are minimized to reduce the noise.This method has became more effective used.But with this technique, the process needs to have shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive is normally a sort of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun steering wheel, a planetary steering 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 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 may be the sun wheel, sunlight wheel and the planet wheel often engage, two external equipment meshing rotation direction is definitely 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, is the internal tooth and the outer gear meshing, the rotation direction between the two may be the same.The amount of planetary gear depends on the look load of the Planetary reduction travel, usually three or four, the more the quantity of bear the load is greater.
The above may be the Planetary reduction travel gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is a sort 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 take a look.
1. The wrong type variety causes insufficient outcome torque of the Planetary decrease drive.
Some users in the version selection, mistakenly given that the selected rated result torque Planetary reduction travel to meet up the work requirements could be, in fact, it is not, one may be the rated end result torque of the electric motor rated output torque times deceleration ratio, the worthiness obtained in principle ought to 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 engine and the maximum operating torque required in practice.
2. In the process 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 decrease drive 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 some applications must strictly adhere to this criterion.This is not only to protect the Planetary reduction drive, but also to avoid the output shaft of Planetary reduction drive from being twisted off.The primary reason is that, if 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 travelling motor will still make it constantly boost the output force, which might cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque 2 times and thus twist the output shaft of the Planetary reduction drive.

Step two 2: unscrew the screw on the external dustproof hole of of Planetary decrease drive flange, adapt the clamping band of PCS program to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.After that, take away the motor shaft keys.
The 3rd step is to connect the electric motor with Planetary reduction drive by natural means.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be consistent when connected, and the external flange of both should be parallel.If the concentricity isn’t consistent, the engine shaft will be broken or of Planetary reduction drive gear wear.
Furthermore, in the installation, usually do not use hammer and other blows, prevent the axial force or radial force too much harm to the bearing or equipment.Make sure you tighten the mounting bolt before tightening the power 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 goal is to make sure tight connection and flexibility of operation, and stop unnecessary wear and tear.
Prior to the motor and Planetary lowering drive are linked, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, initial screw the unit installation bolts at virtually any diagonal position, but do not screw limited, then screw the unit installation bolts at the different two diagonal positions, and lastly screw the four assembly 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.
