Planetary reduction travel in the utilization of the process there will be some noise, the emergence of the noise, how 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 create it more in line with the requirements of environmental coverage is also an integral research topic at home and abroad.Reducing the apparatus transmission noise of Planetary reduction travel has become an important research theme in the market. Many scholars at home and abroad respect the change of gear tooth engagement stiffness in gear transmission as the primary factor of gear dynamic load, vibration and sound.By modifying the shape, the dynamic load and velocity fluctuation are minimized to lessen the noise.This method has became more effective in practice.But with this method, the process needs to have shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive is a kind of of Planetary reduction travel, what’s 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, the sun wheel and the gear ring are in continuous meshing state.
Located in the guts of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the planet wheel frequently engage, two external gear meshing rotation direction can be opposite.Just as the sun is at the guts of the solar program, the solar wheel is named for its location.Gear band 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 is the same.The number of planetary gear will depend on the look load of the Planetary reduction travel, usually 3 or 4, the more the quantity of bear the load is greater.
The above may be the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is usually a kind of speed of Planetary reduction drive, after that, 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 collection causes insufficient productivity torque of the Planetary lowering drive.
Some users in the model selection, mistakenly so long as the selected rated result torque Planetary reduction travel to meet up the work requirements could be, in fact, it is not, one is the rated outcome torque of the electric motor rated output torque moments deceleration ratio, the worthiness 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. 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 such acceleration and deceleration is definitely too frequent, that may eventually make Planetary decrease drive break the shaft.
Theoretically, the utmost operating torque required by the user must be significantly less than two times the rated output torque of the Planetary reduction drive, especially in some applications must strictly adhere to this criterion.This is simply 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, when there is a problem in equipment installation, the output shaft of the Planetary reduction travel and its load are stuck, the overload capacity of the driving motor will still make it constantly raise 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 travel.
Precision planetary reduction drive
Product Description:
There are two main types based on the output direction: direct type and correct angle type; Planetary equipment systems are used to perform speed reduction because of significant torque. to predict gear noise from a back wheel drive automatic transmission.
There are generally three types according to the number of stages: one-stage deceleration (generally less than 10:1), two-stage deceleration (generally greater than 10:1 and significantly less than or equal to 100:1), and three-stage deceleration (large reduction ratio is 100) :1, the general division principle is greater than 100:1);
Based on the purpose: armed service and civilian;According to the operating environment: normal environment, low temperature environment, clean space environment and vacuum environment;

With the Ever-Power mountain drive you get additional suprisingly low gears which permit you head out climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to verify whether the engine and Planetary reduction drive are in good condition before installation, and strictly check whether the size of every part linked with the electric motor and Planetary reduction travel is matched. Here are the size and coordinating tolerance of the positioning boss, insight shaft and Planetary reduction travel groove of the electric motor.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary lowering drive flange, adjust the clamping ring of PCS program to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.After that, take away the motor shaft keys.
The third step is to connect the electric motor with Planetary reduction travel in a natural way.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the engine must be consistent when connected, and the external flange of both should be parallel.If the concentricity is not consistent, the motor shaft will be broken or of Planetary decrease drive gear wear.
Furthermore, in the installation, do not use hammer and other blows, prevent the axial force or radial force too much harm to the bearing or equipment.Make sure to tighten the mounting bolt prior to tightening the drive bolt.Before installation, wipe apart 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 ensure tight connection and versatility of operation, and stop unnecessary wear and tear.
Prior to the motor and Planetary reduction drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, initially screw the assembly bolts at virtually any diagonal position, but usually do not screw restricted, then screw the assembly bolts at the other two diagonal positions, and finally screw the four installation bolts one by one.Finally, tighten the force bolt.All tightening bolts will be fixed and examined by the torque plate hand in line with the indicated torque data.
Right installation between of Planetary reduction drive and mechanical equipment is the same as correct installation between of Planetary reduction drive and drive engine.The key is to make certain that the output shaft of Planetary reduction drive and the drive portion of the shaft concentricity.
