The hardness of tooth surface can reach 45~55HRC.
Connection method between of Planetary lowering drive and servo motor: holding mode – outcome shaft of servo motor extends into of Planetary lowering drive, servo motor and Planetary reduction travel are connected by flange. There exists a deformable hoop in Planetary lowering drive. By working the locking screw on Planetary lowering travel, the hoop can tighten the axis of the servo motor (the author includes a 0.75KW servo motor with this connection). So for this connection mode, servo motors do not need keyway (of lessons, keyway can also be, but ordering keyway servo motors requires Money and delivery period are longer yo @ @). Some sort of
Connecting mode of_of Planetary reduction drive and servo electric motor: Connecting through exterior coupling. This connection setting uses external coupling, so it needs servo electrical and keyway. Exterior coupling may also use adaptable coupling (flexible shaft) – delicate shaft drive electricity generally does not go beyond 5.5KW, speed may reach 20000 rpm. A kind of
In most cases, the servo motors without brakes and keyways will be the many used and the Ever-Power may be the largest. For this reason, to purchase the servo motors with brakes and keyways, the delivery period is longer, about 4 weeks.
Planetary reduction travel in the utilization of the process there will be some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction travel is mainly caused by the friction, vibration and collision of the transmission gears. How exactly to successfully reduce and decrease the noise to make it more based on the requirements of environmental proper protection is also an integral research topic in the home and abroad.Reducing the gear transmission sound of Planetary reduction drive has become an essential research topic in the market. Many scholars in the home and abroad regard the change of equipment tooth engagement stiffness in equipment transmission as the key factor of gear dynamic load, vibration and noises.By modifying the shape, the dynamic load and velocity fluctuation are minimized to reduce the noise.This method has proved to be more effective used.But with this technique, the process will need shape modification equipment, the majority of small factories often can not be implemented.
Planetary reduction drive can be a kind of of Planetary reduction travel, 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 frame, allowing the planetary wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the apparatus ring are in regular meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the planet wheel often engage, two external gear meshing rotation direction is normally opposite.Just as the sun is at the center of the solar program, the solar wheel is named for its location.Gear ring is the internal gear, it and the planet wheel often meshing, is the inner tooth and the outer gear meshing, the rotation direction between the two is the same.The quantity of planetary gear will depend on the design load of the Planetary reduction travel, usually 3 or 4, the more the number of bear the strain is greater.
The above is the Planetary reduction travel equipment transmission structure of the primary content.
Planetary speed of Planetary reduction drive is usually a kind of speed of Planetary reduction drive, then, 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 selection causes insufficient outcome torque of the Planetary lowering drive.
Some users in the style selection, mistakenly given that the selected rated productivity torque Planetary reduction drive to meet up the work requirements could be, in fact, it isn’t, one is the rated productivity torque of the engine rated output torque situations deceleration ratio, the value obtained in principle ought to be less than the merchandise sample to supply similar Planetary reduction travel rated result torque.The other is to consider the overload capacity of the drive engine and the maximum operating torque required in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary reduction drive exceeds 2 times of its ranked output torque, and such acceleration and deceleration is too frequent, which will eventually make Planetary decrease 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 some applications must strictly comply with this criterion.This is simply 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, 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 traveling motor will still make it constantly improve 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 therefore twist the output shaft of the Planetary reduction drive.
Precision planetary reduction drive
Product Description:
There are two main types according to the output direction: straight type and proper angle type; Planetary gear systems are used to perform speed reduction due to significant torque. to predict equipment noise from a rear wheel drive automated transmission.
There are usually three types in line with the number of stages: one-stage deceleration (generally significantly 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 (significant reduction ratio is 100) :1, the overall division principle is higher than 100:1);
Based on the purpose: military and civilian;In line with the operating environment: typical environment, low temp environment, clean bedroom 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-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 confirm whether the engine and Planetary reduction travel are in good condition before installation, and strictly check whether the size of each part linked with the electric motor and Planetary reduction travel is matched. Listed below are the size and matching tolerance of the positioning boss, insight shaft and Planetary reduction travel groove of the engine.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, modify the clamping band of PCS program to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.After that, remove the motor shaft keys.
The 3rd step is to hook up the motor with Planetary reduction travel naturally.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the motor must be steady when connected, and the outer flange of both should be parallel.If the concentricity isn’t consistent, the electric motor shaft will be broken or of Planetary lowering drive gear wear.
In addition, in the installation, usually do not use hammer and other blows, prevent the axial force or radial force too much damage to the bearing or equipment.Make sure you tighten the mounting bolt before tightening the pressure 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 overall flexibility of operation, and prevent unnecessary wear and tear.
Before the motor and Planetary lowering drive are linked, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, primary screw the unit installation bolts at virtually any diagonal position, but usually do not screw tight, then screw the unit installation bolts at the various other two diagonal positions, and lastly screw the four assembly 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.
Right installation between of Planetary reduction drive and mechanical apparatus is equivalent to correct installation between of Planetary reduction travel and drive electric motor.The main element is to ensure that the output shaft of Planetary reduction travel and the drive the main shaft concentricity.
servo engine of Planetary reduction travel Planetary reduction drive of Planetary reduction drive rated input increase to 18000 RPM (about of Planetary reduction drive itself size, the greater the speed of Planetary reduction travel, small the rated input speed) above, industrial-grade servo electric motor of Planetary reduction travel output torque is normally not more than 2000 nm, special significant torque servo engine of Planetary reduction drive can do more than 10000 nm. Working temp in 25 ℃ to 100 ℃ or so, by changing the grease can transform its working heat range.Planetary reduction travel: the primary transmission structure is definitely: planetary wheel, solar wheel, outer gear ring.Weighed against other reduction gear, servo engine reduction gear has large rigidity, high precision (one stage can achieve less than 1 point),(double stage can perform less than 3 things), high transmission performance (single stage in 95-99%), high torque/volume ratio, life maintenance free features.Because of these characteristics, servo motor of Planetary reduction drive is mainly installed in the stepper electric motor and servo motor or perhaps brushless engine, used to lessen the speed, increase the torque, matching inertia.Rated input speed of servo motor of Planetary reduction drive can are as long as 18000rpm(related to the size of Planetary reduction drive itself.
