Connection setting between of Planetary decrease drive and servo electric motor: holding mode – productivity shaft of servo motor extends into of Planetary decrease drive, servo motor and Planetary reduction drive are linked by flange. There is a deformable hoop in Planetary lowering drive. By working the locking screw on Planetary reduction travel, the hoop can tighten the axis of the servo motor (the author has a 0.75KW servo electric motor with this connection). Therefore for this connection function, servo motors do not need keyway (of training, keyway can also be, but purchasing keyway servo motors requires Money and delivery period are longer yo @ @). Some sort of
Connecting mode of_of Planetary decrease drive and servo engine: Connecting through external coupling. This connection method uses external coupling, so it needs servo electric and keyway. Exterior coupling may also use versatile coupling (flexible shaft) – delicate shaft drive power generally does not exceed 5.5KW, speed can reach 20000 rpm. Some sort of
In most cases, the servo motors without brakes and keyways will be the many used and the Ever-Power may be the largest. Consequently, to purchase the servo motors with brakes and keyways, the delivery period is much longer, about 4 weeks.
Planetary reduction drive in the utilization of the process you will see some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction travel 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 in line with the requirements of environmental coverage is also an integral research topic at home and overseas.Reducing the apparatus transmission noise of Planetary reduction travel has become a significant research subject matter in the industry. Many scholars at home and abroad respect the change of gear tooth engagement stiffness in gear transmission as the key factor of gear dynamic load, vibration and noises.By modifying the shape, the powerful load and velocity fluctuation are minimized to reduce 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’t be implemented.
Planetary reduction drive is a kind of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear carries a sun wheel, a planetary wheel, and a gear ring, wherein the planetary steering wheel is supported by a set axis of the planetary frame, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the gear ring are in regular meshing state.
Located in the center of the planetary equipment transmission mechanism may be the sun wheel, sunlight wheel and the earth wheel sometimes engage, two external equipment meshing rotation direction is certainly opposite.Just as sunlight is at the center of the solar program, the solar wheel is known as for its location.Gear band is the interior gear, it and the earth wheel often meshing, is the interior tooth and the outer gear meshing, the rotation direction between the two is the same.The quantity of planetary gear depends on the look load of the Planetary reduction travel, usually three or four, the more the number of bear the strain is greater.
The above may be the Planetary reduction travel equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a sort 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 collection causes insufficient output torque of the Planetary lowering drive.
Some users in the version selection, mistakenly given that the selected rated output torque Planetary reduction drive to meet up the work requirements can 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 value obtained in principle should be less than the product sample to supply 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 in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the outcome shaft of the Planetary lowering drive exceeds two times of its rated output torque, and such acceleration and deceleration is usually too frequent, which will eventually make Planetary reduction travel break the shaft.
Theoretically, the utmost operating torque required simply by an individual must be less than two times the rated output torque of the Planetary reduction drive, especially in some applications must strictly comply with 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, 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 motor will still make it constantly boost the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque 2 times and therefore twist the output shaft of the Planetary reduction drive.

With the Ever-Vitality mountain drive you gain additional very low gears which allow you choose climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to confirm whether the electric motor and Planetary reduction travel are in good condition before installation, and strictly check if the size of every part connected with the engine and Planetary reduction drive is matched. Here are the size and matching tolerance of the positioning boss, source shaft and Planetary reduction drive groove of the engine.
Step two 2: unscrew the screw on the external dustproof hole of of Planetary decrease drive flange, adapt the clamping ring of PCS system to align the medial side hole with the dustproof hole, insert the internal hexagon to tighten.After that, take away the motor shaft keys.
The third step is to connect the electric motor with Planetary reduction travel normally.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the motor must be consistent when connected, and the external flange of the two should be parallel.If the concentricity isn’t consistent, the motor shaft will be broken or of Planetary decrease drive gear wear.
In addition, in the installation, do not use hammer and different blows, prevent the axial force or radial force an excessive amount of damage to the bearing or equipment.Make sure you tighten the mounting bolt just before tightening the force bolt.Before installation, wipe apart 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, preventing unnecessary wear and tear.
Before the motor and Planetary decrease drive are linked, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, primary screw the installation bolts at any diagonal position, but do not screw limited, then screw the assembly bolts at the different two diagonal positions, and lastly screw the four assembly bolts one by one.Finally, tighten the force bolt.All tightening bolts shall be fixed and examined by the torque plate hand according to the indicated torque data.
Right installation between of Planetary reduction drive and mechanical devices is equivalent to accurate installation between of Planetary reduction travel and drive motor.The key is to make sure that the output shaft of Planetary reduction drive and the drive portion of the shaft concentricity.
