Connection setting between of Planetary reduction drive and servo motor: holding mode – outcome shaft of servo engine extends into of Planetary decrease drive, servo motor and Planetary reduction travel are linked by flange. You will find a deformable hoop in Planetary decrease drive. By functioning the locking screw on Planetary lowering travel, the hoop can tighten the axis of the servo motor (the author has a 0.75KW servo engine with this connection). Hence for this connection method, servo motors do not require keyway (of program, keyway may also be, but ordering keyway servo motors requires Money and delivery period are longer yo @ @). A kind of
Connecting mode of_of Planetary lowering drive and servo engine: Connecting through exterior coupling. This connection function uses exterior coupling, so that it needs servo electric and keyway. External coupling can also use flexible coupling (flexible shaft) – smooth shaft drive electrical power generally does not surpass 5.5KW, speed may reach 20000 rpm. Some sort of
In most cases, the servo motors without brakes and keyways are the most used and the Ever-Power is the largest. For this reason, to purchase the servo motors with brakes and keyways, the delivery period is much longer, 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 drive is mainly caused by the friction, vibration and collision of the transmission gears. How exactly to efficiently reduce and reduce the noise to create it more in line with the requirements of environmental protection is also an integral research topic at home and overseas.Reducing the gear transmission sound of Planetary reduction travel has become an essential research issue in the market. Many scholars in the home and abroad respect the change of gear tooth engagement stiffness in equipment transmission as the main factor of gear dynamic load, vibration and noises.By modifying the shape, the powerful load and velocity fluctuation are minimized to lessen the noise.This method has became more effective in practice.But with this technique, the process will need shape modification equipment, the majority of small factories often can not be implemented.
Planetary reduction drive is certainly 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 steering wheel, a planetary steering 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 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, the sun wheel and the earth wheel generally engage, two external gear meshing rotation direction is certainly opposite.Just as sunlight is at the center of the solar program, the solar wheel is known as for its location.Gear ring is the interior gear, it and the planet wheel often meshing, may be the internal tooth and the outer gear meshing, the rotation direction between the two is the same.The quantity of planetary gear depends upon the look load of the Planetary reduction drive, usually 3 or 4, the more the number of bear the strain is greater.
The above may be the Planetary reduction travel gear transmission structure of the key content.
Planetary speed of Planetary reduction drive is definitely 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 collection causes insufficient output torque of the Planetary reduction drive.
Some users in the unit selection, mistakenly so long as the selected rated productivity torque Planetary reduction travel to meet the work requirements can be, in fact, it is not, one is the rated end result torque of the electric motor rated output torque instances deceleration ratio, the value obtained in principle should be less than the product sample to supply similar Planetary reduction drive 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 productivity shaft of the Planetary reduction drive exceeds 2 times of its rated output torque, and this sort of acceleration and deceleration is definitely too frequent, that will eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required simply by the user must be 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 not only to 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, 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 raise 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 thus twist the output shaft of the Planetary reduction drive.
Precision planetary reduction drive
Product Description:
There are two main types in line with the output direction: directly type and right angle type; Planetary equipment systems are used to perform speed reduction because of significant torque. to predict equipment noise from a backside wheel drive automatic transmission.
There are generally three types based on 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 (huge reduction ratio is 100) :1, the overall division principle is greater than 100:1);
Based on the purpose: armed service and civilian;According to the operating environment: typical environment, low temp environment, clean space environment and vacuum environment;
Our speed of Planetary reduction drive planetary gear for heavy-duty applications, including; conveyers, cranes, crawlers, and excavators. With the Ever-Electrical power mountain drive you gain additional very low gears which permit you go climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The first step is to verify whether the motor and Planetary reduction drive are in good condition before installation, and strictly check whether the size of every part connected with the electric motor and Planetary reduction travel is matched. Here are the size and matching tolerance of the positioning boss, type shaft and Planetary decrease drive groove of the engine.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, adjust the clamping band of PCS system to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.After that, take away the motor shaft keys.
The third step is to connect the motor with Planetary reduction travel obviously.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the motor must be steady when connected, and the external flange of both must 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, do not use hammer and additional blows, avoid the axial force or radial force an excessive amount of damage to the bearing or gear.Be sure to tighten the installation bolt before tightening the push 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 goal is to ensure tight connection and versatility of operation, and stop unnecessary deterioration.
Prior to the motor and Planetary decrease drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, 1st screw the set up bolts at any kind of diagonal position, but usually do not screw restricted, then screw the unit installation bolts at the other two diagonal positions, and finally screw the four 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.
Right installation between of Planetary reduction travel and mechanical apparatus is the same as right 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 part of the shaft concentricity.
