In Planetary reduction drive family, the Planetary reduction travel with its small size, huge transmission efficiency, huge reduction range, substantial precision many advantages, and is trusted in servo, stepping, dc and additional transmission systems.Its function is in the premise of ensuring accuracy transmission, mainly used to lessen the rotation rate and increase torque and reduce the load/motor rotational inertia ratio.In order to help nearly all users to create good use of the Planetary reduction travel, this paper analyzes the causes of Planetary reduction travel and the drive motor shaft breaking, and introduces in detail how exactly to properly install the Planetary reduction drive.
Right installation, use and maintenance of of Planetary reduction drive is an important hyperlink to ensure the standard operation of mechanical equipment.For that reason, when you install the Planetary reduction drive, you should be sure to strictly follow the next installation related matters, carefully assemble and use.
The initial step is to verify whether the electric motor and Planetary reduction travel are intact before installation, and strictly check whether the size of every part connected with the electric motor and Planetary reduction drive matches, this is actually the size of the positioning boss, input shaft and Planetary reduction travel groove of the motor and matching tolerance.
The second step is to unscrew the screw on the outer dustproof hole of Planetary reduction drive flange, adapt the clamping ring of PCS system to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, take away the motor shaft keys.

Connection function between of Planetary reduction drive and servo engine: holding mode – output shaft of servo electric motor extends into of Planetary lowering drive, servo engine and Planetary reduction travel are linked by flange. There exists a deformable hoop in Planetary lowering drive. By operating the locking screw on Planetary lowering travel, the hoop can tighten the axis of the servo engine (the author has a 0.75KW servo electric motor with this connection). Therefore for this connection setting, servo motors usually do not require keyway (of training, keyway can also be, but purchasing keyway servo motors needs Money and delivery period are longer yo @ @). Some sort of
Linking mode of_of Planetary lowering drive and servo electric motor: Connecting through external coupling. This connection method uses external coupling, so it needs servo electric and keyway. External coupling may also use adaptable coupling (flexible shaft) – smooth shaft drive electrical power generally does not surpass 5.5KW, speed may reach 20000 rpm. Some sort of
Generally speaking, the servo motors without brakes and keyways are the many used and the Ever-Power is the largest. As a result, to purchase the servo motors with brakes and keyways, the delivery period is longer, about 4 weeks.
Planetary reduction travel in the usage of the process there will be 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 good requirements of environmental proper protection is also an integral research topic at home and overseas.Reducing the gear transmission sound of Planetary reduction travel has become an important research subject matter in the market. Many scholars at home and abroad respect the change of equipment tooth engagement stiffness in gear 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 reduce the noise.This technique has proved to be more effective in practice.But with this technique, the process needs to have shape modification equipment, nearly all small factories often can’t be implemented.
Planetary reduction drive is usually a sort of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun steering wheel, a planetary wheel, and a gear band, wherein the planetary wheel is supported by a fixed axis of the planetary framework, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, sunlight wheel and the gear ring are in regular meshing state.
Located in the guts of the planetary equipment transmission mechanism is the sun wheel, the sun wheel and the planet wheel generally engage, two external equipment meshing rotation direction is certainly opposite.Just as sunlight is at the center of the solar system, the solar wheel is named for its location.Gear ring is the interior gear, it and the earth wheel often meshing, is the interior tooth and the external gear meshing, the rotation direction between your two is the same.The number of planetary gear depends upon the design load of the Planetary reduction travel, usually 3 or 4, the more the quantity of bear the strain is greater.
The above is the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is usually a sort of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive in the process of using the cause of the shaft break what?Let’s have a look.
1. The wrong type collection causes insufficient result torque of the Planetary decrease drive.
Some users in the version selection, mistakenly so long as the selected rated outcome torque Planetary reduction drive to meet up the work requirements can be, in fact, it isn’t, one is the rated result torque of the motor rated output torque moments deceleration ratio, the value obtained in principle ought to be less than the product sample to supply similar Planetary reduction travel rated outcome torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the outcome shaft of the Planetary lowering drive exceeds 2 times of its rated output torque, and these kinds of acceleration and deceleration is certainly too frequent, that may eventually make Planetary decrease travel break the shaft.
Theoretically, the maximum operating torque required simply by the user must be less than 2 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 prevent 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 own load are stuck, the overload capacity of the generating motor will still make it constantly boost the output force, which may cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque 2 times and so twist the output shaft of the Planetary reduction travel.
Precision planetary reduction drive
Product Description:
There are two main types according to the output direction: right type and correct angle type; Planetary gear systems are used to execute speed reduction because of huge torque. to predict gear noise from a rear wheel drive automatic transmission.
There are usually three types in line with the number of stages: one-stage deceleration (generally less than 10:1), two-stage deceleration (generally higher than 10:1 and less than or add up to 100:1), and three-stage deceleration (large reduction ratio is 100) :1, the general division principle is higher than 100:1);
Based on the purpose: army and civilian;According to the operating environment: normal environment, low temp environment, clean room environment and vacuum environment;
Our speed of Planetary reduction travel planetary gear for heavy-duty applications, including; conveyers, cranes, crawlers, and excavators. With the Ever-Vitality mountain drive you gain additional suprisingly low gears which enable you get climb the the majority of extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to verify whether the motor and Planetary reduction travel are in good condition before installation, and strictly check if the size of each part linked with the electric motor and Planetary reduction drive is matched. Here are the size and matching tolerance of the positioning boss, type shaft and Planetary lowering travel groove of the engine.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, change the clamping ring of PCS program 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 connect the engine with Planetary reduction drive in a natural way.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the engine must be regular when connected, and the external flange of both should be parallel.If the concentricity is not consistent, the electric motor shaft will be broken or of Planetary lowering drive gear wear.
Furthermore, in the installation, do not use hammer and different blows, prevent the axial force or radial force too much harm to the bearing or gear.Make sure you tighten the mounting bolt prior to tightening the induce bolt.Before installation, wipe apart the anti-corrosion oil of motor input shaft, positioning boss and connecting component of of Planetary reduction drive with gasoline or zinc-sodium water.Its goal is to make sure tight connection and versatility of operation, preventing unnecessary wear and tear.
Before the motor and Planetary reduction drive are connected, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, 1st screw the set up bolts at any kind of diagonal position, but usually do not screw limited, then screw the installation bolts at the additional two diagonal positions, and lastly screw the four installation bolts one at a time.Finally, tighten the force bolt.All tightening bolts shall 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 apparatus is the same as accurate installation between of Planetary reduction travel and drive electric motor.The key is to make sure that the output shaft of Planetary reduction travel and the drive the main shaft concentricity.
servo electric motor of Planetary reduction drive Planetary reduction travel of Planetary reduction drive rated input increase to 18000 RPM (about of Planetary reduction travel itself size, the greater the quickness of Planetary reduction travel, the smaller the rated input quickness) above, industrial-grade servo electric motor of Planetary reduction drive output torque is generally only 2000 nm, special large torque servo electric motor of Planetary reduction travel can do more than 10000 nm. Working temp in 25 ℃ to 100 ℃ or so, by changing the grease can change its working temperatures.Planetary reduction drive: the key transmission structure is certainly: planetary wheel, solar wheel, outer gear ring.Compared with different reduction gear, servo motor reduction gear has huge rigidity, high precision (solitary stage can achieve less than 1 stage),(double stage can achieve less than 3 items), high transmission effectiveness (single stage in 95-99%), high torque/volume ratio, life free of maintenance features.Due to these characteristics, servo motor of Planetary reduction travel is mostly installed in the stepper engine and servo motor or perhaps brushless electric motor, used to reduce the speed, enhance the torque, matching inertia.Rated input speed of servo engine of Planetary reduction travel can are as long as 18000rpm(related to how big is Planetary reduction drive itself.
