Full load efficiency: transmitting efficiency of of Planetary reduction drive under maximum load (result torque of fault quit).
Working existence: the cumulative working time of Planetary decrease drive at rated load and rated input speed.
Rated torque: it’s the torque that the ranked life allows for long running time.When the output swiftness is 100 r/min, the life span of Planetary reduction drive is the average life, above this value, the common life of Planetary reduction drive will be reduced.Planetary reduction drive fails when the output torque exceeds twice.
Edit materials and heat treatment
The weight of the Planetary reduction servo drive planetary gear transmission device is normally proportional to the weight of the gear, and the weight of the gear 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 ought to be broadly used.There are several heat treatment solutions to obtain gear with hard tooth surface, such as for example 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 small size, high transmission efficiency, wide reduction range, high precision many advantages, and is trusted in servo, stepping, dc and additional transmission systems.Its function is in the premise of ensuring precision transmission, 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 create good utilization of the Planetary reduction drive, this paper analyzes the sources of Planetary reduction drive and the drive motor shaft breaking, and introduces at length how exactly to properly install the Planetary reduction drive.
Appropriate installation, use and maintenance of of Planetary reduction drive can be an important hyperlink to ensure the standard operation of mechanical equipment.As a result, when you install the Planetary reduction drive, please be certain to strictly follow the following installation related matters, thoroughly assemble and use.
The first step is to confirm if the electric motor and Planetary reduction drive are intact before installation, and strictly check whether the size of every part connected with the motor and Planetary reduction drive fits, this is actually 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, adapt 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 little 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 area can reach 45~55HRC.
Connection setting between of Planetary reduction drive and servo electric motor: holding mode – result shaft of servo electric motor extends into of Planetary reduction drive, servo motor and Planetary reduction drive are linked by flange. There is a deformable hoop in Planetary reduction drive. By operating the locking screw on Planetary decrease drive, the hoop can tighten the axis of the servo electric motor (the author includes a 0.75KW servo engine with this connection). So for this connection setting, servo motors usually do not need keyway (of course, keyway may also be, but buying keyway servo motors requires Money and delivery period are longer yo @ @). Some sort of
Connecting mode of_of Planetary decrease drive and servo motor: Connecting through external coupling. This connection mode uses external coupling, so that it needs servo electrical and keyway. Exterior coupling may also use versatile coupling (flexible shaft) – gentle shaft drive power generally does not exceed 5.5KW, speed can reach 20000 rpm. A kind of
Generally speaking, the servo motors without brakes and keyways will be 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 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 successfully reduce and reduce the noise to create it more good requirements of environmental protection is also an integral research topic at home and overseas.Reducing the apparatus transmission noise of Planetary decrease drive has become an important research topic in the industry. Many scholars at home and abroad respect the change of gear tooth engagement stiffness in equipment transmission as the primary factor of gear dynamic load, vibration and sound.By modifying the form, the dynamic 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, nearly all small factories often can not be implemented.
Planetary reduction drive can be some 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 framework, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, the sun wheel and the gear ring are in continuous meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the planet wheel often engage, two external equipment meshing rotation direction is opposite.Just as sunlight is at the guts of the solar system, the solar wheel is named because of its location.Gear ring is the inner gear, it and the earth wheel often meshing, may be the inner tooth and the external gear meshing, the rotation direction between the two is the same.The amount of planetary gear depends upon the look 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 usually a kind of speed of Planetary reduction drive, then, 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 incorrect type selection causes insufficient result torque of the Planetary decrease drive.
Some users in the model selection, mistakenly provided that the selected rated result torque Planetary reduction drive to meet up the work requirements could be, in fact, it isn’t, one may be the rated output torque of the motor rated output torque situations deceleration ratio, the worthiness obtained in principle ought to 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 maximum operating torque required used.
2. In the process 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 maximum operating torque required simply by the user 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 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 drive and its own load are stuck, the overload capacity of the generating 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 thus twist the output shaft of the Planetary reduction drive.
Precision planetary decrease drive
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 back wheel drive automated 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 greater than 10:1 and significantly less than or equal to 100:1), and three-stage deceleration (large reduction ratio is 100) :1, the general division principle is greater than 100:1);
Based on the purpose: military and civilian;Based on the operating environment: standard 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 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 if the engine and Planetary reduction drive are in good shape before installation, and strictly check whether the size of every part linked with the electric motor and Planetary reduction drive is matched. Listed below are the size and complementing tolerance of the positioning boss, insight shaft and Planetary reduction drive groove of the engine.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary reduction drive flange, modify the clamping band of PCS program to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, remove the motor shaft keys.
The third step is for connecting the electric 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 constant 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 reduction drive gear wear.
Furthermore, in the installation, do not use hammer and additional blows, avoid the axial force or radial force too much harm to the bearing or equipment.Make sure to tighten the mounting bolt just before tightening the drive 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 flexibility of operation, and stop unnecessary wear and tear.
Planetary reduction drivePlanetary reduction drive
Before the motor and Planetary reduction drive are linked, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, 1st screw the installation bolts at any kind of diagonal position, but usually do not screw restricted, 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 will be fixed and checked by the torque plate hand based on the indicated torque data.
Correct installation between of Planetary reduction drive and mechanical equipment is the same as correct installation between of Planetary reduction drive and drive electric motor.The main element is to make sure that the output shaft of Planetary reduction drive and the drive area of the shaft concentricity.
servo electric motor of Planetary reduction drive Planetary reduction drive of Planetary reduction drive rated input increase to 18000 RPM (about of Planetary reduction drive itself size, the greater the speed of Planetary reduction drive, the smaller the rated input speed) above, industrial-grade servo engine of Planetary reduction drive output torque is normally only 2000 nm, special large torque servo electric motor of Planetary reduction drive can do more than 10000 nm. Functioning temperature in 25 ℃ to 100 ℃ or so, by changing the grease can change its operating temperature.Planetary reduction drive: the primary transmission structure is: planetary wheel, solar wheel, outer gear ring.Weighed against various other reduction gear, servo motor reduction gear offers high rigidity, high accuracy (single stage can achieve 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 free of maintenance features.Because of these characteristics, servo motor of Planetary reduction drive is mostly installed in the stepper electric motor and servo motor or brushless electric motor, used to lessen the speed, improve the torque, matching inertia.Ranked input speed of servo electric motor of Planetary reduction drive can reach up to 18000rpm(related to how big is Planetary reduction drive itself.
