Connection function between of Planetary lowering drive and servo motor: holding mode – result shaft of servo motor extends into of Planetary lowering drive, servo engine and Planetary reduction travel are linked by flange. There exists a deformable hoop in Planetary decrease drive. By working the locking screw on Planetary decrease travel, the hoop can tighten the axis of the servo engine (the author has a 0.75KW servo electric motor with this connection). And so for this connection function, servo motors do not need keyway (of study course, keyway can also be, but ordering keyway servo motors needs Money and delivery time are longer yo @ @). Some sort of
Linking mode of_of Planetary decrease drive and servo electric motor: Connecting through exterior coupling. This connection function uses exterior coupling, so it needs servo electric and keyway. Exterior coupling can also use versatile coupling (flexible shaft) – delicate shaft drive electrical power generally does not go beyond 5.5KW, speed can reach 20000 rpm. Some sort of

Planetary reduction travel in the application 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 due to the friction, vibration and collision of the transmission gears. How exactly to effectively reduce and reduce the noise to make it more based on the requirements of environmental security is also a key research topic at home and overseas.Reducing the gear transmission sound of Planetary reduction travel has become an essential research subject matter in the market. Many scholars in the home and abroad respect the change of equipment tooth engagement stiffness in equipment transmission as the primary 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 became more effective used.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 drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun wheel, a planetary steering wheel, and a gear band, wherein the planetary steering wheel is supported by a fixed axis of the planetary body, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the apparatus ring are in frequent meshing state.
Located in the guts of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the earth wheel quite often engage, two external gear meshing rotation direction is opposite.Just as sunlight is at the guts of the solar system, the solar wheel is known as for its location.Gear band is the interior gear, it and the planet wheel often meshing, is the internal tooth and the external gear meshing, the rotation direction between your two may be the same.The number of planetary gear will depend on the look load of the Planetary reduction drive, usually 3 or 4, the more the amount of bear the load is greater.
The above is the Planetary reduction drive gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is usually a kind of speed of Planetary reduction drive, in that case, 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 output torque of the Planetary reduction drive.
Some users in the unit selection, mistakenly as long as the selected rated end result torque Planetary reduction travel to meet up the work requirements can be, in fact, it is not, one is the rated end result torque of the motor rated output torque times deceleration ratio, the value obtained in principle ought to be less than the product sample to provide similar Planetary reduction drive rated outcome torque.The other is to consider the overload capacity of the drive motor and the utmost operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the productivity shaft of the Planetary reduction drive exceeds two times of its rated output torque, and these kinds of acceleration and deceleration is too frequent, which will eventually make Planetary reduction drive break the shaft.
Theoretically, the maximum operating torque required simply by the user 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 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 drive and its load are stuck, the overload capacity of the driving a car motor will still make it constantly raise the output force, which may cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque two times and so 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: right type and correct angle type; Planetary equipment systems are used to perform speed reduction due to large torque. to predict equipment noise from a rear wheel drive automatic transmission.
There are generally three types based on the number of stages: one-stage deceleration (generally significantly 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 overall division principle is greater than 100:1);
Based on the purpose: armed service and civilian;Based on the operating environment: common environment, low temperatures environment, clean place environment and vacuum environment;
Our speed of Planetary reduction drive planetary gear for heavy-duty applications, including; conveyers, cranes, crawlers, and excavators. With the Ever-Electricity mountain drive you gain additional very low gears which allow you head out climb the most 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 if the size of each part linked with the engine and Planetary reduction travel is matched. Here are the size and complementing tolerance of the positioning boss, type shaft and Planetary lowering travel groove of the electric motor.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary lowering drive flange, adapt the clamping band of PCS system to align the side hole with the dustproof hole, insert the internal hexagon to tighten.From then on, take away the motor shaft keys.
The 3rd step is to hook up the motor with Planetary reduction drive naturally.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the engine must be steady 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, do not use hammer and different blows, avoid the axial force or radial force an excessive amount of damage to the bearing or equipment.Make sure to tighten the mounting bolt before tightening the drive bolt.Before installation, wipe aside the anti-corrosion oil of motor input shaft, positioning boss and connecting portion of of Planetary reduction drive with gasoline or zinc-sodium water.Its goal is to make sure tight connection and overall flexibility of operation, and stop unnecessary deterioration.
Before the motor and Planetary decrease drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, primary screw the set up bolts at virtually any diagonal position, but do not screw limited, then screw the assembly bolts at the various other two diagonal positions, and lastly screw the four set up bolts one at a time.Finally, tighten the force bolt.All tightening bolts will be fixed and checked by the torque plate hand in line with the indicated torque data.
Correct installation between of Planetary reduction drive and mechanical equipment is the same as appropriate installation between of Planetary reduction travel and drive motor.The key is to make sure that the output shaft of Planetary reduction travel and the drive area of the shaft concentricity.
