Connection function between of Planetary lowering drive and servo electric motor: holding mode – outcome shaft of servo electric motor extends into of Planetary lowering drive, servo motor and Planetary reduction travel are connected by flange. There is a deformable hoop in Planetary lowering drive. By functioning the locking screw on Planetary reduction travel, the hoop can tighten the axis of the servo electric motor (the author has a 0.75KW servo motor with this connection). Hence for this connection method, servo motors usually do not need keyway (of course, keyway can also be, but purchasing keyway servo motors requires Money and delivery time are longer yo @ @). A kind of
Linking mode of_of Planetary lowering drive and servo motor: Connecting through exterior coupling. This connection method uses exterior coupling, so it needs servo electric and keyway. External coupling can also use versatile coupling (flexible shaft) – gentle shaft drive electric 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 the majority of used and the Ever-Power is the largest. For that reason, to order 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 caused by the friction, vibration and collision of the transmission gears. How to effectively reduce and reduce the noise to make it more based on the requirements of environmental coverage is also an integral research topic at home and abroad.Reducing the apparatus transmission noise of Planetary reduction drive has become an important 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 main factor of gear dynamic load, vibration and noise.By modifying the shape, the dynamic load and velocity fluctuation are minimized to lessen the noise.This method has proved to be more effective used.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 a sort of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun wheel, a planetary wheel, and a gear ring, wherein the planetary wheel is supported by a fixed axis of the planetary body, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the apparatus ring are in frequent meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the earth wheel often engage, two external equipment meshing rotation direction can be opposite.Just as sunlight is at the center of the solar program, the solar wheel is known as because of its location.Gear band is the inner gear, it and the planet wheel often meshing, is the internal tooth and the external gear meshing, the rotation direction between the two is the same.The number of planetary gear is determined by the design load of the Planetary reduction drive, usually three or four, the more the amount of bear the load is greater.
The above is the Planetary reduction travel gear transmission structure of the key content.
Planetary speed of Planetary reduction drive can be a kind of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive along the way of using the cause of the shaft break what?Let’s take a look.
1. The wrong type variety causes insufficient productivity torque of the Planetary reduction drive.
Some users in the unit selection, mistakenly as long as the selected rated productivity torque Planetary reduction travel to meet up the work requirements could be, in fact, it is not, one is the rated end result torque of the motor rated output torque occasions deceleration ratio, the worthiness obtained in principle should be less than the product sample to provide similar Planetary reduction travel rated outcome torque.The other is to consider the overload capacity of the drive motor and the maximum operating torque required used.
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 ranked output torque, and this sort of acceleration and deceleration is certainly too frequent, that will eventually make Planetary decrease drive break the shaft.
Theoretically, the utmost operating torque required simply by an individual must be significantly 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 simply not and then protect the Planetary reduction drive, but also to avoid 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 driving a car motor will still make it constantly increase the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and so twist the output shaft of the Planetary reduction travel.
Precision planetary reduction travel
Product Description:
There are two main types according to the output direction: directly type and right angle type; Planetary equipment systems are used to execute speed reduction because of large torque. to predict equipment noise from a backside wheel drive computerized transmission.
There are usually three types based on the number of stages: one-stage deceleration (generally significantly less than 10:1), two-stage deceleration (generally greater than 10:1 and less than or add up to 100:1), and three-stage deceleration (significant reduction ratio is 100) :1, the general division principle is higher than 100:1);
According to the purpose: armed service and civilian;According to the operating environment: common environment, low temperature environment, clean area 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-Electricity mountain drive you gain additional suprisingly low gears which enable you head out climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The first step is to confirm whether the motor and Planetary reduction travel are in good shape before installation, and strictly check whether the size of each part connected with the electric motor and Planetary reduction travel is matched. Here are the size and matching tolerance of the positioning boss, source shaft and Planetary lowering drive groove of the engine.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary lowering drive flange, adapt the clamping band of PCS program to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.From then on, remove the motor shaft keys.
The 3rd step is to hook up the electric motor with Planetary reduction travel in a natural way.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 the two should be parallel.If the concentricity isn’t consistent, the motor shaft will be broken or of Planetary lowering drive gear wear.
Furthermore, in the installation, do not use hammer and other blows, avoid the axial force or radial force an excessive amount of harm to the bearing or equipment.Be sure to tighten the mounting bolt just before tightening the force bolt.Before installation, wipe aside the anti-rust 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 ensure tight connection and overall flexibility of operation, preventing unnecessary deterioration.
Before the motor and Planetary reduction drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, initial screw the set up bolts at any kind of diagonal position, but usually do not screw restricted, then screw the set up 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 examined by the torque plate hand according to the indicated torque data.
Right installation between of Planetary reduction travel and mechanical devices is equivalent to correct installation between of Planetary reduction drive and drive motor.The key is to ensure that the output shaft of Planetary reduction travel and the drive portion of the shaft concentricity.
