Full load efficiency: transmission efficiency of of Planetary decrease drive under optimum load (output torque of fault stop).
Working lifestyle: the cumulative working time of Planetary reduction drive in rated load and rated input speed.
Rated torque: it’s the torque that the rated life allows for long running time.When the output quickness is 100 r/min, the life span of Planetary reduction drive may be the average life, further than 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 generally proportional to the weight of the apparatus, and the weight of the gear has a great relationship with the material and heat treatment hardness.For instance, at the same power, the weight of the carburized hardened equipment will be about 1/3 of the weight of the tempered gear.Therefore, according to the structural characteristics of Planetary reduction drive and the strain nature of gears, hardtooth surface gears ought to be widely used.There are numerous heat treatment solutions to obtain gear with hard tooth surface, such as surface quenching, overall quenching, carburizing quenching, nitriding, etc., which should be selected according to the characteristics of Planetary reduction drive.
Planetary reduction drive
In Planetary reduction drive family, the Planetary reduction drive using its little size, high transmitting efficiency, wide reduction range, high precision many advantages, and is trusted in servo, stepping, dc and other transmitting systems.Its function is in the premise of ensuring precision tranny, mainly used to lessen the rotation rate and increase torque and decrease the load/engine rotational inertia ratio.To be able to help nearly all users to make good usage of the Planetary reduction drive, this paper analyzes the causes of Planetary reduction drive and the drive engine 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 standard procedure of mechanical equipment.Therefore, when you install the Planetary reduction drive, please make certain to strictly follow the following installation related matters, properly assemble and use.
The first step is to confirm whether the engine and Planetary reduction drive are intact before installation, and strictly check whether the size of every part linked with the electric 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 medial side hole with the dustproof hole, insert the inner hexagon to tighten.After that, remove 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 can reach 45~55HRC.
Connection mode between of Planetary decrease drive and servo electric motor: holding mode – output shaft of servo engine extends into of Planetary reduction drive, servo engine and Planetary decrease drive are linked by flange. There is a deformable hoop in Planetary reduction drive. By operating the locking screw on Planetary reduction 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 mode, servo motors usually do not need keyway (of training course, keyway can also be, but ordering keyway servo motors requires Money and delivery time are longer yo @ @). Some sort of
Linking mode of_of Planetary decrease drive and servo engine: Connecting through external coupling. This connection mode uses exterior coupling, so it needs servo electric and keyway. External coupling can also use flexible coupling (flexible shaft) – smooth shaft drive power generally will not go beyond 5.5KW, speed can reach 20000 rpm. Some sort of
In most cases, the servo motors without brakes and keyways are the many 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 4 weeks.
Planetary reduction drive in the usage of the process there will be some noise, the emergence of the noise, how exactly to deal with it?
Planetary reduction drive
The noise of Planetary reduction drive is mainly due to the friction, vibration and collision of the transmission gears. How to efficiently reduce and decrease the noise to create it more based on the requirements of environmental protection is also a key research topic in the home and overseas.Reducing the apparatus transmission noise of Planetary reduction drive has become a significant research subject in the industry. Many scholars at home and abroad respect the change of gear tooth engagement stiffness in equipment transmission as the main factor of gear dynamic load, vibration and noise.By modifying the shape, the dynamic load and velocity fluctuation are minimized to reduce the noise.This method has proved to be more effective used.But with this method, the process needs to have shape modification equipment, nearly all small factories often can not be implemented.
Planetary reduction drive is usually a kind of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sunlight 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 assisting 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, the sun wheel and the earth wheel frequently engage, two external gear meshing rotation direction can be opposite.Just as the sun 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 planet wheel often meshing, may be the internal tooth and the external gear meshing, the rotation direction between your 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 strain 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, 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 output torque of the Planetary decrease drive.
Some users in the model selection, mistakenly so long as the selected rated result 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 occasions deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise sample to supply similar Planetary reduction drive rated result torque.The other is to consider the overload capacity of the drive motor 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 such acceleration and deceleration can be too frequent, that will eventually make Planetary reduction 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 adhere to 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, when 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 raise the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and thus twist the output shaft of the Planetary reduction drive.
Precision planetary reduction drive
Product Description:
There are two main types according to the output direction: straight type and correct angle type; Planetary equipment systems are used to perform speed reduction due to large torque. to predict equipment noise from a back wheel drive automatic transmission.
There are generally 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 less than or equal 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 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 get 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 whether the electric motor and Planetary reduction drive are in good condition before installation, and strictly check if 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, insight shaft and Planetary decrease drive groove of the motor.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary reduction drive flange, adapt the clamping band of PCS system to align the side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, take away the motor shaft keys.
The 3rd 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 external flange of the two must be parallel.If the concentricity isn’t consistent, the motor shaft will be broken or of Planetary decrease drive gear wear.
In addition, in the installation, do not use hammer and additional blows, avoid the axial force or radial force too much harm to the bearing or gear.Be sure to tighten the installation bolt just before 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 versatility of operation, and stop unnecessary wear and tear.
Planetary reduction drivePlanetary reduction drive
Before the motor and Planetary reduction drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, initial screw the set up bolts at any diagonal position, but usually do not screw restricted, then screw the set up bolts at the other two diagonal positions, and finally screw the four installation bolts one by one.Finally, tighten the force bolt.All tightening bolts will be fixed and examined by the torque plate hand based on the indicated torque data.
Right installation between of Planetary reduction drive and mechanical equipment is the same as right installation between of Planetary reduction drive and drive motor.The key is to ensure that the output shaft of Planetary reduction drive and the drive section of the shaft concentricity.
servo 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 higher the quickness of Planetary reduction drive, the smaller the rated input acceleration) above, industrial-grade servo electric motor of Planetary reduction drive output torque is generally only 2000 nm, special large torque servo electric motor of Planetary reduction drive can do a lot more than 10000 nm. Working temperature in 25 ℃ to 100 ℃ or so, by changing the grease can change its operating temperature.Planetary reduction drive: the main transmission structure can be: planetary wheel, solar wheel, outer gear ring.Compared with additional reduction gear, servo electric motor reduction gear offers high rigidity, high accuracy (single stage can achieve less than 1 point),(double stage can perform 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 reduction drive is mostly installed in the stepper electric motor and servo motor or brushless electric motor, used to reduce the speed, improve the torque, matching inertia.Rated input speed of servo motor of Planetary reduction drive can reach up to 18000rpm(related to the size of Planetary reduction drive itself.
