Connection mode between of Planetary reduction drive and servo engine: holding mode – outcome shaft of servo electric motor extends into of Planetary decrease drive, servo engine and Planetary reduction travel are linked by flange. There is a deformable hoop in Planetary reduction drive. By functioning 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). Hence for this connection setting, servo motors usually do not need keyway (of program, keyway can also be, but buying keyway servo motors requires Money and delivery period are longer yo @ @). Some sort of
Connecting mode of_of Planetary reduction drive and servo engine: Connecting through external coupling. This connection setting uses external coupling, so it needs servo electrical and keyway. External coupling may also use flexible coupling (flexible shaft) – delicate shaft drive electrical power generally does not go beyond 5.5KW, speed can reach 20000 rpm. A kind of
Generally speaking, the servo motors without brakes and keyways are the the majority of used and the Ever-Power may be the largest. For this reason, to order the servo motors with brakes and keyways, the delivery period is longer, about 4 weeks.
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 caused by the friction, vibration and collision of the transmission gears. How to effectively reduce and decrease the noise to create it more good requirements of environmental safety is also a key research topic at home and abroad.Reducing the gear transmission noises of Planetary reduction travel has become an important research matter in the market. Many scholars in the home and abroad regard the change of gear tooth engagement stiffness in gear transmission as the key factor of gear dynamic load, vibration and noises.By modifying the form, the powerful load and velocity fluctuation are minimized to reduce the noise.This technique has proved to be more effective in practice.But with this method, the process needs to have shape modification equipment, the majority of 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 have a look.
A planetary gear carries a sun wheel, a planetary steering wheel, and a gear ring, wherein the planetary steering wheel is supported by a fixed axis of the planetary framework, allowing the planetary wheel to rotate on the supporting axis.The planetary wheel, sunlight wheel and the gear ring are in continuous meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the earth wheel sometimes engage, two external gear meshing rotation direction is usually opposite.Just as sunlight is at the guts of the solar program, the solar wheel is named because of its location.Gear band is the interior gear, it and the planet wheel often meshing, may be the interior tooth and the outer gear meshing, the rotation direction between your two is the same.The amount of planetary gear depends upon the design load of the Planetary reduction drive, usually three or four, the more the number of bear the load is greater.
The above may be the Planetary reduction drive gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a kind of speed of Planetary reduction drive, then, the planetary speed of Planetary reduction drive along the way of using the cause of the shaft break what?Let’s have a look.
1. The wrong type variety causes insufficient end result torque of the Planetary reduction drive.
Some users in the style selection, mistakenly provided that the selected rated result torque Planetary reduction travel to meet up the work requirements can be, in fact, it is not, one is the rated productivity torque of the engine rated output torque circumstances deceleration ratio, the value obtained in principle should be less than the product sample to provide similar Planetary reduction drive rated result torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the outcome shaft of the Planetary decrease drive exceeds 2 times of its rated output torque, and this sort of acceleration and deceleration is too frequent, that will eventually make Planetary reduction drive break the shaft.
Theoretically, the utmost operating torque required simply by an individual must be 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 main reason is that, if there is a problem in equipment installation, the output shaft of the Planetary reduction travel and its own load are stuck, the overload capacity of the driving a vehicle motor will still make it constantly raise 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 therefore twist the output shaft of the Planetary reduction drive.

The initial step is to verify whether the electric motor and Planetary reduction drive are in good shape before installation, and strictly check whether the size of each part connected with the motor and Planetary reduction travel is matched. Listed below are the size and matching tolerance of the positioning boss, input shaft and Planetary reduction travel groove of the engine.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary lowering drive flange, adjust the clamping ring of PCS system to align the side hole with the dustproof hole, insert the interior hexagon to tighten.After that, remove the motor shaft keys.
The third step is to connect the engine with Planetary reduction travel by natural means.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be steady when connected, and the external flange of the two must be parallel.If the concentricity isn’t consistent, the engine shaft will be broken or of Planetary lowering drive gear wear.
Furthermore, in the installation, do not use hammer and different blows, avoid the axial force or radial force too much harm to the bearing or equipment.Be sure to tighten the mounting bolt ahead of tightening the force 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 make sure tight connection and flexibility of operation, and stop unnecessary wear and tear.
Before the motor and Planetary lowering drive are connected, the motor shaft keyway ought to 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 tight, then screw the set up 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 checked by the torque plate hand based on the indicated torque data.
Appropriate installation between of Planetary reduction travel and mechanical apparatus is the same as right installation between of Planetary reduction drive and drive motor.The main element is to make certain that the output shaft of Planetary reduction travel and the drive part of the shaft concentricity.
