Full load efficiency: tranny efficiency of of Planetary reduction drive under maximum load (result torque of fault end).
Working lifestyle: the cumulative working time of Planetary reduction drive at rated load and rated input speed.
Rated torque: it is the torque that the rated life allows for long running time.When the output velocity is 100 r/min, the life span of Planetary reduction drive is the average life, beyond 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 generally proportional to the weight of the gear, and the weight of the apparatus has a great relationship with the materials and heat therapy hardness.For example, 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 characteristics of Planetary reduction drive and the load nature of gears, hardtooth surface gears ought to be widely used.There are numerous heat treatment methods to obtain gear with hard tooth surface, such as surface quenching, overall quenching, carburizing quenching, nitriding, etc., that ought to be selected based on the characteristics of Planetary decrease drive.

In Planetary reduction drive family, the Planetary reduction drive using its little size, high tranny efficiency, wide reduction range, high precision many advantages, and is trusted in servo, stepping, dc and other tranny systems.Its function is in the premise of ensuring precision transmission, mainly used to reduce the rotation speed and increase torque and decrease the load/engine rotational inertia ratio.To be able to help nearly all users to create good usage of the Planetary reduction drive, this paper analyzes the sources of Planetary reduction drive and the drive motor shaft breaking, and introduces in detail how to properly install the Planetary reduction drive.
Appropriate installation, use and maintenance of of Planetary reduction drive is certainly an important link to ensure the normal operation of mechanical equipment.As a result, when you install the Planetary reduction drive, make sure you be certain to strictly follow the next installation related matters, carefully assemble and use.
The first rung on the ladder is to confirm whether the engine and Planetary reduction drive are intact before installation, and strictly check if the size of every part linked with the engine and Planetary reduction drive matches, here is the size of the positioning boss, input shaft and Planetary reduction drive groove of the engine 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 area quenching methods are high-frequency quenching (for small gears) and flame quenching (for huge gears).The surface 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 area can reach 45~55HRC.
Connection mode between of Planetary decrease drive and servo electric motor: holding mode – result shaft of servo engine extends into of Planetary reduction drive, servo motor and Planetary decrease drive are connected by flange. There is a deformable hoop in Planetary decrease drive. By operating the locking screw on Planetary decrease drive, the hoop can tighten the axis of the servo motor (the author has a 0.75KW servo electric motor with this connection). Therefore for this connection setting, servo motors do not need keyway (of training course, keyway can also be, but purchasing keyway servo motors requires Money and delivery time are longer yo @ @). A kind of
Connecting mode of_of Planetary reduction drive and servo electric motor: Connecting through external coupling. This connection mode uses external coupling, so that it needs servo electric and keyway. Exterior coupling can also use versatile coupling (flexible shaft) – soft shaft drive power generally does not exceed 5.5KW, speed can reach 20000 rpm. Some sort of
In most cases, the servo motors without brakes and keyways will be the many used and the Ever-Power may be the largest. As a result, to purchase the servo motors with brakes and keyways, the delivery period can be 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?
Planetary reduction drive
The noise of Planetary reduction drive is principally due to the friction, vibration and collision of the transmission gears. How exactly to effectively reduce and decrease the noise to make it more in line with the requirements of environmental security is also an integral research topic at home and overseas.Reducing the apparatus transmission noise of Planetary reduction drive has become a significant research subject in the market. Many scholars at home and abroad respect the change of gear tooth engagement stiffness in gear transmission as the primary factor of gear powerful load, vibration and sound.By modifying the form, the powerful load and velocity fluctuation are minimized to reduce the noise.This technique has became more effective used.But with this method, the process needs to have shape modification equipment, nearly all small factories often can’t be implemented.
Planetary reduction drive is definitely 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 ring, wherein the planetary wheel is supported by a fixed axis of the planetary framework, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, sunlight wheel and the gear ring are in constant meshing state.
Located in the guts of the planetary gear transmission mechanism is the sun wheel, sunlight wheel and the planet wheel often engage, two external gear meshing rotation direction is opposite.Just as the sun is at the center of the solar program, the solar wheel is known as because of its location.Gear band is the internal gear, it and the earth wheel often meshing, is the inner tooth and the outer gear meshing, the rotation direction between the two may be the same.The amount of planetary gear depends upon 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 gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is usually some sort of speed of Planetary reduction drive, then, the planetary speed of Planetary reduction drive along the way of using the reason for the shaft break what?Let’s take a look.
1. The wrong type selection causes insufficient result torque of the Planetary reduction drive.
Some users in the model selection, mistakenly so long as the selected rated output torque Planetary decrease drive to meet up the work requirements can be, in fact, it is not, one is the rated output torque of the engine rated output torque times deceleration ratio, the worthiness obtained in principle should be less than the product sample to supply similar Planetary decrease drive rated result torque.The other is to consider the overload capacity of the drive motor and the maximum operating torque required in practice.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary reduction drive exceeds 2 times of its ranked output torque, and this kind of acceleration and deceleration is usually too frequent, that may eventually make Planetary decrease drive break the shaft.
Theoretically, the utmost operating torque required simply by the user must be less than 2 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 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 drive and its load are stuck, the overload capacity of the traveling 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 2 times and therefore twist the output shaft of the Planetary reduction drive.
Precision planetary reduction drive
There are two main types based on the output direction: directly type and right angle type; Planetary gear systems are accustomed to perform speed reduction due to large torque. to predict gear noise from a back wheel drive automatic transmission.
There are generally three types according to the number of stages: one-stage deceleration (generally less than 10:1), two-stage deceleration (generally higher than 10:1 and significantly less than or add up 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: military and civilian;According to the operating environment: regular environment, low temperature environment, clean room 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 very low gears which allow you proceed climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
Planetary gear reduction drive
The first step is to confirm if the electric motor and Planetary reduction drive are in good shape before installation, and strictly check whether the size of each part connected with the electric motor and Planetary reduction drive is matched. Listed below are the size and matching tolerance of the positioning boss, input shaft and Planetary reduction drive groove of the engine.
Step two 2: unscrew the screw on the external 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 internal hexagon to tighten.From then on, take away the motor shaft keys.
The 3rd step is to connect the motor with Planetary reduction drive naturally.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the electric motor must be consistent when connected, and the outer flange of the two should be parallel.If the concentricity isn’t consistent, the engine shaft will be broken or of Planetary decrease drive gear wear.
In addition, 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 equipment.Be sure to tighten the installation bolt just before tightening the power bolt.Before installation, wipe aside 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 versatility of operation, and prevent unnecessary wear and tear.
Planetary reduction drivePlanetary reduction drive
Prior to the motor and Planetary reduction drive are linked, 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 do not screw restricted, then screw the set up bolts at the other two diagonal positions, and lastly screw the four installation bolts one by one.Finally, tighten the force bolt.All tightening bolts shall be fixed and checked by the torque plate hand according to the indicated torque data.
Appropriate installation between of Planetary reduction drive and mechanical equipment is the same as correct installation between of Planetary reduction drive and drive engine.The key is to make sure that the output shaft of Planetary reduction drive and the drive section of the shaft concentricity.
servo engine 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 velocity of Planetary reduction drive, the smaller the rated input swiftness) above, industrial-grade servo electric motor of Planetary reduction drive output torque is normally only 2000 nm, special huge torque servo engine of Planetary reduction drive can perform a lot more than 10000 nm. Working temperature in 25 ℃ to 100 ℃ or so, by changing the grease can change its functioning temperature.Planetary reduction drive: the primary transmission structure is certainly: planetary wheel, solar wheel, outer gear ring.Weighed against other reduction gear, servo engine reduction gear offers high rigidity, high precision (single stage can perform less than 1 stage),(double stage can achieve less than 3 factors), high transmission performance (single stage in 95-99%), high torque/volume ratio, life maintenance free features.Due to these characteristics, servo electric motor of Planetary decrease drive is mostly installed in the stepper electric motor and servo engine or brushless engine, used to lessen the speed, enhance the torque, matching inertia.Ranked input speed of servo engine of Planetary reduction drive can are as long as 18000rpm(related to the size of Planetary reduction drive itself.
