Full load efficiency: transmission efficiency of of Planetary reduction drive under optimum load (result torque of fault stop).
Working existence: the cumulative working time of Planetary decrease drive in rated load and rated insight speed.
Rated torque: it’s the torque that the ranked life allows for long running time.When the output acceleration is 100 r/min, the life span of Planetary reduction drive is 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 normally proportional to the weight of the apparatus, and the weight of the apparatus has a great relationship with the materials and heat treatment hardness.For example, at the same power, the weight of the carburized hardened equipment will be about 1/3 of the weight of the tempered equipment.Therefore, based on the structural features of Planetary reduction drive and the strain nature of gears, hardtooth surface gears ought to be widely used.There are various 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 with its little size, high transmission efficiency, wide reduction range, high precision many advantages, and is trusted in servo, stepping, dc and additional transmitting systems.Its function is in the premise of ensuring precision transmitting, mainly used to lessen the rotation swiftness and increase torque and decrease the load/electric motor rotational inertia ratio.To be able to help the majority of users to create good use of the Planetary reduction drive, this paper analyzes the causes of Planetary reduction drive and the drive motor shaft breaking, and introduces in detail how exactly to properly install the Planetary reduction drive.
Appropriate installation, use and maintenance of of Planetary reduction drive is usually an important link to ensure the normal procedure of mechanical equipment.As a result, when you install the Planetary reduction drive, please make sure to strictly follow the following installation related matters, carefully assemble and use.
The first step is to confirm if 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 matches, this is actually 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 medial side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, 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 is most effective when it includes the base 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 motor: holding mode – output shaft of servo motor extends into of Planetary reduction drive, servo electric 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 electric motor (the author includes a 0.75KW servo electric motor with this connection). So for this connection mode, servo motors do not need keyway (of course, keyway can also be, but purchasing keyway servo motors requires Money and delivery period are longer yo @ @). Some sort of
Linking mode of_of Planetary decrease drive and servo electric motor: Connecting through external coupling. This connection setting uses exterior coupling, so that it needs servo electrical and keyway. Exterior coupling can also use versatile coupling (flexible shaft) – soft shaft drive power generally does not go beyond 5.5KW, speed may reach 20000 rpm. Some sort of
Generally speaking, the servo motors without brakes and keyways are the most used and the Ever-Power is the largest. Consequently, to order the servo motors with brakes and keyways, the delivery period is certainly longer, about 4 weeks.
Planetary reduction drive in the use of the process you will have some noise, the emergence of the noise, how exactly to deal with it?
Planetary reduction drive
The noise of Planetary reduction drive is mainly caused by the friction, vibration and collision of the transmission gears. How to effectively reduce and decrease the noise to create it more based on the requirements of environmental safety is also a key research topic at home and overseas.Reducing the gear transmission noise of Planetary reduction drive has become a significant 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 shape, the dynamic load and velocity fluctuation are minimized to reduce the noise.This technique has proved to be more effective in practice.But with this method, the process will need shape modification equipment, nearly all small factories often can’t be implemented.
Planetary reduction drive is usually some sort of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear carries a sun wheel, a planetary wheel, and a gear ring, wherein the planetary wheel is supported by a set 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 guts of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the planet wheel frequently engage, two external gear meshing rotation direction can be opposite.Just as sunlight is at the guts of the solar program, the solar wheel is named for its location.Gear ring is the internal gear, it and the planet wheel often meshing, is the internal tooth and the external gear meshing, the rotation direction between your two is the same.The amount of planetary gear depends on the design 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 drive gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is certainly some sort 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 take a look.
1. The incorrect 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 the work requirements can be, in fact, it isn’t, one is the rated result torque of the engine rated output torque situations deceleration ratio, the worthiness obtained in principle ought to be less than the merchandise 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 used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary reduction drive exceeds two times of its rated output torque, and such acceleration and deceleration is too frequent, that will eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required by the user must be significantly less than two times the rated output torque of the Planetary reduction drive, especially in a few 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 traveling motor will still make it constantly raise 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 reduction drive
There are two main types based on the output direction: straight type and right angle type; Planetary equipment systems are accustomed to perform speed decrease due to huge torque. to predict equipment noise from a back wheel drive automatic 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 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: regular environment, low temperature environment, clean area 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 suprisingly low gears which allow you move 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 motor and Planetary reduction drive are in good condition before installation, and strictly check whether the size of each part linked with the electric motor and Planetary reduction drive is matched. Here are the size and matching tolerance of the positioning boss, input shaft and Planetary decrease drive groove of the engine.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary reduction drive flange, adjust the clamping band of PCS program 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 to connect the electric motor with Planetary reduction drive normally.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 external flange of both should 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, usually do not use hammer and additional blows, prevent the axial force or radial force too much harm to the bearing or gear.Be sure to tighten the installation bolt 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 make sure 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 ought to be perpendicular to the tightening bolt.To make sure a uniform force, initial screw the installation bolts at any diagonal position, but do not screw restricted, then screw the installation bolts at the other 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 examined by the torque plate hand based on the indicated torque data.
Appropriate installation between of Planetary reduction drive and mechanical equipment is equivalent to right 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 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 swiftness of Planetary reduction drive, small the rated input acceleration) above, industrial-grade servo motor of Planetary reduction drive output torque is generally not more than 2000 nm, special large torque servo engine of Planetary reduction drive can do a lot more than 10000 nm. Working temperature in 25 ℃ to 100 ℃ roughly, by changing the grease can transform its functioning temperature.Planetary reduction drive: the main transmission structure is usually: planetary wheel, solar wheel, outer gear ring.Compared with other reduction gear, servo engine reduction gear provides high rigidity, high accuracy (single stage can achieve less than 1 point),(double stage can achieve less than 3 factors), high transmission efficiency (single stage in 95-99%), high torque/volume ratio, life maintenance free features.Due to these characteristics, servo motor of Planetary reduction drive is mostly installed in the stepper electric motor and servo engine or brushless electric motor, used to lessen the speed, improve the torque, matching inertia.Ranked input speed of servo motor of Planetary reduction drive can reach up to 18000rpm(related to the size of Planetary reduction drive itself.
