Product parameter editing
Full load efficiency: transmitting efficiency of of Planetary reduction drive under optimum load (result torque of fault stop).
Working lifestyle: the cumulative working period of Planetary decrease drive at rated load and rated insight speed.
Rated torque: it is the torque that the rated life allows for long running time.When the output swiftness is 100 r\/min, the life of Planetary reduction drive is the average life, outside of this value, the average life of Planetary reduction drive will be reduced.Planetary reduction drive fails when the output torque exceeds twice.
Edit material and heat treatment
The weight of the Planetary reduction servo drive planetary gear transmission device is normally proportional to the weight of the apparatus, and the weight of the apparatus includes a great relationship with the material and heat treatment hardness.For instance, at the same power, the weight of the carburized hardened gear will be about 1\/3 of the weight of the tempered equipment.Therefore, according to the structural features of Planetary reduction drive and the strain nature of gears, hardtooth surface gears should be broadly used.There are plenty of heat treatment solutions to obtain gear with hard tooth surface, such as surface quenching, overall quenching, carburizing quenching, nitriding, etc., which should be selected based on the characteristics of Planetary reduction drive.
Planetary reduction drive
In Planetary reduction drive family, the Planetary reduction drive with its little size, high tranny efficiency, wide reduction range, high precision many advantages, and is trusted in servo, stepping, dc and other transmission systems.Its function is in the premise of ensuring precision tranny, mainly used to reduce the rotation swiftness and increase torque and reduce the load\/electric motor rotational inertia ratio.In order to help nearly all users to make good utilization of the Planetary reduction drive, this paper analyzes the sources of Planetary reduction drive and the drive electric motor shaft breaking, and introduces at length how to properly install the Planetary reduction drive.
Correct installation, use and maintenance of of Planetary reduction drive is usually an important link to ensure the normal operation of mechanical equipment.For that reason, when you install the Planetary reduction drive, please be certain to strictly follow the following installation related matters, properly assemble and use.
The first rung on the ladder is to confirm whether the motor and Planetary reduction drive are intact before installation, and strictly check whether the size of every part connected with the electric motor and Planetary reduction drive matches, here is the size of the positioning boss, input shaft and Planetary reduction drive groove of the motor and matching tolerance.
The next step is to unscrew the screw on the outer dustproof hole of Planetary reduction drive flange, change the clamping ring of PCS system to align the side hole with the dustproof hole, insert the inner hexagon to tighten.After that, take away the motor shaft keys.
Surface hardening editing
Common surface quenching methods are high-frequency quenching (for small gears) and flame quenching (for large gears).The top hardened layer works best when it contains the bottom of the tooth root.The common material for surface quenching is steel whose mass fraction of carbon is approximately 0.35%~0.5%. The hardness of tooth surface can reach 45~55HRC.
Connection setting between of Planetary reduction drive and servo engine: holding mode – output shaft of servo motor extends into of Planetary reduction drive, servo engine and Planetary reduction drive are linked by flange. There is a deformable hoop in Planetary decrease drive. By working the locking screw on Planetary decrease drive, the hoop can tighten the axis of the servo motor (the author has a 0.75KW servo engine with this connection). Therefore for this connection setting, servo motors usually do not require keyway (of course, keyway may also be, but buying keyway servo motors requires Money and delivery period are longer yo @ @). A kind of
Linking mode of_of Planetary decrease drive and servo engine: Connecting through exterior coupling. This connection setting uses exterior coupling, so that it needs servo electric and keyway. External coupling can also use versatile coupling (flexible shaft) – soft shaft drive power generally does not surpass 5.5KW, speed may reach 20000 rpm. Some sort of
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 order the servo motors with brakes and keyways, the delivery period is definitely longer, about four weeks.
Planetary reduction drive in the use of the process you will see some noise, the emergence of the noise, how exactly to deal with it?
Planetary reduction drive
The noise of Planetary reduction drive is principally 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 noise of Planetary decrease drive has become an essential research subject in the industry. Many scholars in the home and abroad respect the change of gear tooth engagement stiffness in equipment transmission as the main factor of gear powerful 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 in practice.But with this method, the process needs to have shape modification equipment, nearly all small factories often can’t be implemented.
Planetary reduction drive can be a kind of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sunlight wheel, a planetary wheel, and a gear band, wherein the planetary wheel is supported by a set axis of the planetary body, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the apparatus ring are in continuous meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, sunlight wheel and the earth wheel frequently engage, two external equipment meshing rotation direction is usually opposite.Just as sunlight is at the center of the solar system, the solar wheel is known as because of its location.Gear ring is the internal gear, it and the earth wheel often meshing, is the internal tooth and the external gear meshing, the rotation direction between your two is the same.The number of planetary gear depends upon the design load of the Planetary reduction drive, usually three or four, the more the amount of bear the load is greater.
The above may be the Planetary reduction drive gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is some sort 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 have a look.
1. The wrong type selection causes insufficient result torque of the Planetary reduction drive.
Some users in the model selection, mistakenly as long as the selected rated output torque Planetary reduction drive to meet up the work requirements can be, in fact, it is not, one is the rated output torque of the electric motor rated output torque moments deceleration ratio, the value obtained in principle should be less than the merchandise sample to provide similar Planetary reduction drive rated result torque.The other is to consider the overload capacity of the drive engine and the utmost operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary decrease drive exceeds two times of its ranked output torque, and this kind of acceleration and deceleration is usually too frequent, that will eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum 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 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 motor will still make it constantly increase the output force, which might cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and therefore twist the output shaft of the Planetary reduction drive.
Precision planetary decrease drive
Product Description:
There are two main types according to the output direction: straight type and correct angle type; Planetary gear systems are accustomed to perform speed reduction due to huge torque. to predict equipment noise from a rear wheel drive automated transmission.
There are usually three types based on the number of stages: one-stage deceleration (generally 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 (large reduction ratio is 100) :1, the overall division principle is greater than 100:1);
Based on the purpose: military and civilian;According to the operating environment: standard environment, low temperature 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 schlumpf mountain drive you gain additional suprisingly low gears which enable you move climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
Planetary gear reduction drive
The first step is to confirm whether the engine and Planetary reduction drive are in good shape before installation, and strictly check if the size of every part connected with the motor and Planetary reduction drive is matched. Here are the size and matching tolerance of the positioning boss, input shaft and Planetary reduction drive groove of the electric motor.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary reduction drive flange, adapt the clamping ring of PCS system to align the side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, remove the motor shaft keys.
The 3rd step is to connect the engine with Planetary reduction drive naturally.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be consistent when connected, and the outer flange of the two should be parallel.If the concentricity is not consistent, the motor shaft will be broken or of Planetary reduction drive gear wear.
Furthermore, in the installation, do not use hammer and various other blows, avoid the axial force or radial force too much harm to the bearing or gear.Make sure to tighten the mounting bolt prior to tightening the pressure bolt.Before installation, wipe away 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 ensure tight connection and flexibility of operation, and stop unnecessary wear and tear.
Planetary reduction drivePlanetary reduction drive
Prior to the motor and Planetary decrease drive are linked, 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 tight, then screw the installation 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 based on the indicated torque data.
Right installation between of Planetary reduction drive and mechanical tools is equivalent to right installation between of Planetary reduction drive and drive engine.The key is to ensure that the output shaft of Planetary reduction drive and the drive section of the shaft concentricity.
servo electric motor of Planetary reduction drive Planetary reduction drive of Planetary reduction drive rated input speed up to 18000 RPM (about of Planetary reduction drive itself size, the greater the rate of Planetary reduction drive, small the rated input acceleration) above, industrial-grade servo engine of Planetary reduction drive output torque is normally not more than 2000 nm, special large torque servo electric motor of Planetary reduction drive can do more than 10000 nm. Functioning temperature in 25 \u2103 to 100 \u2103 or so, by changing the grease can change its functioning temperature.Planetary reduction drive: the primary transmission structure is usually: planetary wheel, solar wheel, outer gear ring.Weighed against additional reduction gear, servo motor reduction gear offers high rigidity, high precision (single stage can achieve less than 1 stage),(double stage can achieve less than 3 factors), high transmission efficiency (single stage in 95-99%), high torque\/volume ratio, life free of maintenance features.Because of these characteristics, servo engine of Planetary reduction drive is mainly installed in the stepper electric motor and servo motor or brushless engine, used to reduce the speed, enhance the torque, matching inertia.Ranked input speed of servo motor of Planetary reduction drive can reach up to 18000rpm(related to how big is Planetary reduction drive itself.<\/p>","protected":false},"excerpt":{"rendered":"
