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 apparatus has a great relationship with the material and heat therapy hardness.For instance, at the same ability, the excess weight of the carburized hardened gear will be about 1/3 of the weight of the tempered gear.Therefore, according to the structural characteristics of Planetary reduction drive and the load nature of gears, hardtooth surface gears should be generally used.There are many heat treatment methods 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.
In Planetary reduction travel family, the Planetary reduction drive using its small size, great transmission efficiency, large reduction range, high precision a large number of advantages, and is widely used in servo, stepping, dc and other tranny systems.Its function is in the premise of ensuring accuracy transmission, mainly used to reduce the rotation velocity and increase torque and reduce the load/motor rotational inertia ratio.So as to help nearly all users to create good usage of the Planetary reduction travel, this paper analyzes the causes of Planetary reduction travel and the drive 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 an important hyperlink to ensure the standard procedure of mechanical equipment.For that reason, when you install the Planetary reduction drive, you should make certain to strictly follow the following installation related matters, cautiously assemble and use.
The first step is to verify whether the electric motor and Planetary reduction drive are intact before installation, and strictly check whether the size of each part linked with the electric motor and Planetary reduction travel matches, this is actually the size of the positioning boss, input shaft and Planetary reduction drive groove of the motor and matching tolerance.
The second step is to unscrew the screw on the outer dustproof hole of Planetary reduction travel flange, modify 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.

The hardness of tooth surface area can reach 45~55HRC.
Connection method between of Planetary decrease drive and servo motor: holding mode – outcome shaft of servo electric motor extends into of Planetary decrease drive, servo electric motor and Planetary reduction travel are connected by flange. You will find a deformable hoop in Planetary lowering drive. By working the locking screw on Planetary decrease drive, the hoop can tighten the axis of the servo motor (the author includes a 0.75KW servo motor with this connection). Therefore for this connection function, servo motors do not need keyway (of program, keyway can also be, but buying keyway servo motors needs Money and delivery period are longer yo @ @). A kind of
Linking mode of_of Planetary lowering drive and servo motor: Connecting through exterior coupling. This connection mode uses external coupling, so it needs servo electric and keyway. External coupling may also use flexible coupling (flexible shaft) – soft shaft drive electrical power generally does not surpass 5.5KW, speed can 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. Consequently, to order the servo motors with brakes and keyways, the delivery period is for a longer time, about 4 weeks.
Planetary reduction travel in the use of the process you will have some noise, the emergence of the noise, how exactly to deal with it?
The noise of Planetary reduction travel is mainly due to the friction, vibration and collision of the transmission gears. How exactly to effectively reduce and reduce the noise to make it more based on the requirements of environmental proper protection is also an integral research topic in the home and abroad.Reducing the apparatus transmission sound of Planetary reduction drive has become a significant research issue in the industry. Many scholars in the home and abroad respect the change of gear tooth engagement stiffness in gear transmission as the primary factor of gear powerful load, vibration and noises.By modifying the shape, the powerful load and velocity fluctuation are minimized to reduce the noise.This method has became more effective used.But with this technique, the process will need shape modification equipment, nearly all small factories often can not be implemented.
Planetary reduction drive is certainly a sort of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sun steering wheel, a planetary wheel, and a gear ring, wherein the planetary wheel is supported by a fixed axis of the planetary body, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, the sun wheel and the gear ring are in frequent meshing state.
Located in the guts of the planetary gear transmission mechanism is the sun wheel, sunlight wheel and the planet wheel generally engage, two external equipment meshing rotation direction is definitely opposite.Just as the sun is at the center of the solar system, the solar wheel is named for its location.Gear band is the interior gear, it and the earth wheel often meshing, may be the interior tooth and the external gear meshing, the rotation direction between the two is the same.The number of planetary gear depends on the look load of the Planetary reduction travel, usually 3 or 4, the more the amount 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 definitely a kind of speed of Planetary reduction drive, in that case, the planetary speed of Planetary reduction drive in the process of using the reason for the shaft break what?Let’s have a look.
1. The wrong type assortment causes insufficient end result torque of the Planetary decrease drive.
Some users in the model selection, mistakenly provided that the selected rated output torque Planetary reduction travel to meet up the work requirements can be, in fact, it isn’t, 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 reduction drive rated outcome 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 outcome shaft of the Planetary reduction drive exceeds 2 times of its ranked output torque, and these kinds of acceleration and deceleration is usually too frequent, that may eventually make Planetary lowering travel break the shaft.
Theoretically, the utmost operating torque required 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 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 load are stuck, the overload capacity of the traveling 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 so twist the output shaft of the Planetary reduction drive.
Precision planetary reduction drive
Product Description:
There are two main types based on the output direction: directly type and right angle type; Planetary gear systems are used to execute speed reduction due to large torque. to predict gear noise from a rear wheel drive programmed transmission.
There are usually three types in line with the number of stages: one-stage deceleration (generally significantly less than 10:1), two-stage deceleration (generally higher than 10:1 and less than or add up to 100:1), and three-stage deceleration (large reduction ratio is 100) :1, the overall division principle is greater than 100:1);
According to the purpose: military and civilian;Based on the operating environment: common environment, low heat range environment, clean area environment and vacuum environment;
Our speed of Planetary reduction travel planetary gear for heavy-duty applications, including; conveyers, cranes, crawlers, and excavators. With the Ever-Vitality mountain drive you get additional very low gears which allow you move climb the many extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial 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 linked with the motor and Planetary reduction drive is matched. Here are the size and coordinating tolerance of the positioning boss, suggestions shaft and Planetary decrease travel groove of the engine.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, adapt the clamping ring of PCS system to align the side hole with the dustproof hole, insert the internal hexagon to tighten.From then on, remove the motor shaft keys.
The 3rd step is to connect the motor with Planetary reduction travel by natural means.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the electric motor must be steady when connected, and the outer flange of both 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, usually do not use hammer and other blows, prevent the axial force or radial force an excessive amount of damage to the bearing or equipment.Be sure to tighten the mounting bolt ahead of tightening the power bolt.Before installation, wipe aside the anti-rust oil of motor input shaft, positioning boss and connecting portion of of Planetary reduction drive with gasoline or zinc-sodium water.Its goal is to ensure tight connection and versatility of operation, and prevent unnecessary wear and tear.
Before the motor and Planetary decrease drive are connected, the motor shaft keyway ought to be perpendicular to the tightening bolt.To ensure a uniform force, first screw the set up bolts at any kind of diagonal position, but do not screw restricted, then screw the set up bolts at the various other two diagonal positions, and finally screw the four set up bolts one by one.Finally, tighten the force bolt.All tightening bolts shall be fixed and examined by the torque plate hand in line with the indicated torque data.
Accurate installation between of Planetary reduction travel and mechanical apparatus is equivalent to appropriate installation between of Planetary reduction travel and drive motor.The key is to make sure that the output shaft of Planetary reduction travel and the drive the main shaft concentricity.
