Generally speaking, the servo motors without brakes and keyways will be the most used and the Ever-Power is the largest. As a result, to purchase the servo motors with brakes and keyways, the delivery period is for a longer time, about 4 weeks.
Planetary reduction drive in the use of the process there will be some noise, the emergence of the noise, how 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 successfully reduce and decrease the noise to create it more in line with the requirements of environmental protection is also a key research topic at home and overseas.Reducing the apparatus transmission noises of Planetary reduction drive has become an important research topic in the industry. Many scholars at 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 dynamic load and velocity fluctuation are minimized to reduce the noise.This technique has proved to be more effective used.But with this method, the process will need shape modification equipment, nearly all small factories often can not be implemented.
Planetary reduction drive is normally a kind of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sun wheel, a planetary wheel, and a gear band, wherein the planetary wheel is supported by a set axis of the planetary frame, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, the sun wheel and the apparatus ring are in constant meshing state.
Located in the center of the planetary equipment transmission mechanism may be the sun wheel, the sun wheel and the planet wheel quite often engage, two external equipment meshing rotation direction is certainly opposite.Just as the sun is at the center of the solar system, the solar wheel is named for its location.Gear band is the inner gear, it and the planet wheel often meshing, may be the inner tooth and the outer gear meshing, the rotation direction between the two is the same.The number of planetary gear depends on the look load of the Planetary reduction drive, usually 3 or 4, the more the quantity of bear the load is greater.
The above is the Planetary reduction travel gear 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 in the process of using the cause of the shaft break what?Let’s take a look.
1. The wrong type variety causes insufficient outcome torque of the Planetary lowering drive.
Some users in the style selection, mistakenly given that the selected rated end result torque Planetary reduction travel to meet the work requirements could be, in fact, it is not, one is the rated output torque of the engine rated output torque instances deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise sample to supply similar Planetary reduction travel rated output torque.The other is to consider the overload capacity of the drive engine and the maximum operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the productivity shaft of the Planetary decrease drive exceeds 2 times of its ranked output torque, and this sort of acceleration and deceleration can be too frequent, that will eventually make Planetary reduction drive break the shaft.
Theoretically, the maximum operating torque required simply by an individual must be significantly less than two times the rated output torque of the Planetary reduction drive, especially in a few 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, 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 driving a car motor will still make it constantly boost the output force, which might cause the force of the output bearing of the Planetary reduction drive 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 in line with the output direction: right type and correct angle type; Planetary equipment systems are used to execute speed reduction because of huge torque. to predict gear noise from a rear wheel drive programmed transmission.
There are generally three types according to 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 (huge reduction ratio is 100) :1, the overall division principle is higher than 100:1);
Based on the purpose: army and civilian;In line with the operating environment: normal environment, low temperature environment, clean area environment and vacuum environment;

Here are the size and complementing tolerance of the positioning boss, source shaft and Planetary lowering travel groove of the electric motor.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, adjust the clamping ring of PCS system to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.From then on, take away the motor shaft keys.
The third step is to hook up the engine with Planetary reduction drive by natural means.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the motor must be steady when connected, and the external flange of the two must be parallel.If the concentricity isn’t consistent, the electric motor shaft will be broken or of Planetary decrease drive gear wear.
In addition, in the installation, usually do not use hammer and additional blows, prevent the axial force or radial force an excessive amount of harm to the bearing or equipment.Make sure to tighten the installation bolt before tightening the power 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 ensure tight connection and overall flexibility of operation, and stop 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 ensure a uniform force, first screw the set up bolts at virtually any diagonal position, but usually do not screw tight, then screw the set up bolts at the different two diagonal positions, and finally screw the four set up bolts one at a time.Finally, tighten the force bolt.All tightening bolts shall be fixed and examined by the torque plate hand according to the indicated torque data.
Correct installation between of Planetary reduction drive and mechanical gear is equivalent to accurate installation between of Planetary reduction travel and drive engine.The main element is to make certain that the output shaft of Planetary reduction drive and the drive part of the shaft concentricity.
