The hardness of tooth surface area can reach 45~55HRC.
Connection mode between of Planetary decrease drive and servo engine: holding mode – productivity shaft of servo electric motor extends into of Planetary decrease drive, servo electric motor and Planetary reduction drive are connected by flange. You will find a deformable hoop in Planetary lowering drive. By operating the locking screw on Planetary lowering drive, the hoop can tighten the axis of the servo electric motor (the author has a 0.75KW servo engine with this connection). So for this connection function, servo motors usually do not need keyway (of lessons, keyway may also be, but ordering keyway servo motors needs Money and delivery period are longer yo @ @). A kind of
Connecting mode of_of Planetary reduction drive and servo engine: Connecting through exterior coupling. This connection method uses external coupling, so it needs servo electrical and keyway. Exterior coupling can also use flexible coupling (flexible shaft) – very soft shaft drive vitality generally does not exceed 5.5KW, speed can 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 for a longer time, about 4 weeks.
Planetary reduction travel 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 successfully reduce and reduce the noise to create it more in line with the requirements of environmental safety is also an integral research topic in the home and abroad.Reducing the apparatus transmission noises of Planetary reduction travel has become an important research issue in the market. Many scholars in the home and abroad respect the change of gear tooth engagement stiffness in gear transmission as the primary factor of gear dynamic load, vibration and sound.By modifying the shape, the dynamic load and velocity fluctuation are minimized to lessen the noise.This method has became more effective used.But with this technique, the process needs to have shape modification equipment, nearly all small factories often can not 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 steering wheel, a planetary wheel, and a gear ring, wherein the planetary steering wheel is supported by a set axis of the planetary framework, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, the sun 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 often engage, two external gear meshing rotation direction is normally opposite.Just as sunlight is at the guts of the solar system, the solar wheel is known as because of its location.Gear band is the inner gear, it and the planet wheel often meshing, may be the internal tooth and the external gear meshing, the rotation direction between your 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 number of bear the load is greater.
The above is the Planetary reduction drive equipment transmission structure of the primary content.
Planetary speed of Planetary reduction drive is a sort of speed of Planetary reduction drive, in that case, the planetary speed of Planetary reduction drive in the process of using the reason for the shaft break what?Let’s take a look.
1. The wrong type collection causes insufficient productivity torque of the Planetary decrease drive.
Some users in the model selection, mistakenly as long as the selected rated productivity torque Planetary reduction drive to meet the work requirements could be, in fact, it is not, one may be the rated outcome torque of the engine rated output torque circumstances deceleration ratio, the worthiness obtained in principle should 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 electric motor and the maximum operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the end result shaft of the Planetary lowering drive exceeds two times of its ranked output torque, and such acceleration and deceleration is definitely too frequent, that may eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required by the user must be significantly less than 2 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 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 travel and its own load are stuck, the overload capacity of the traveling 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 therefore twist the output shaft of the Planetary reduction travel.
Precision planetary reduction drive
Product Description:
There are two main types based on the output direction: straight type and proper angle type; Planetary gear systems are used to execute speed reduction because of huge torque. to predict gear noise from a back wheel drive automatic transmission.
There are generally three types in line with the number of stages: one-stage deceleration (generally 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 (huge reduction ratio is 100) :1, the general division principle is greater than 100:1);
In line with the purpose: armed service and civilian;In line with the operating environment: typical environment, low heat 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-Ability mountain drive you get additional very low gears which enable you head out climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The first step is to verify whether the electric motor and Planetary reduction drive are in good shape before installation, and strictly check if the size of every part linked with the electric motor and Planetary reduction travel is matched. Here are the size and coordinating tolerance of the positioning boss, suggestions shaft and Planetary reduction drive groove of the motor.
Step two 2: unscrew the screw on the external dustproof hole of of Planetary lowering drive flange, modify the clamping ring of PCS system to align the 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 travel in a natural way.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the electric motor must be constant when connected, and the outer flange of both should be parallel.If the concentricity is not consistent, the electric motor shaft will be broken or of Planetary reduction drive gear wear.
Furthermore, in the installation, do not use hammer and various other blows, prevent the axial force or radial force an excessive amount of harm to the bearing or equipment.Make sure you tighten the installation bolt before tightening the drive bolt.Before installation, wipe apart the anti-rust 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, preventing unnecessary wear and tear.
Before the motor and Planetary decrease drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, initially screw the assembly bolts at any diagonal position, but do not screw tight, then screw the assembly bolts at the different two diagonal positions, and lastly screw the four unit installation bolts one at a time.Finally, tighten the force bolt.All tightening bolts will be fixed and examined by the torque plate hand in line with the indicated torque data.
Correct installation between of Planetary reduction travel and mechanical tools is equivalent to appropriate installation between of Planetary reduction travel and drive engine.The key is to make certain that the output shaft of Planetary reduction drive and the drive section of the shaft concentricity.
