Edit material 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 has a great relationship with the material and heat treatment hardness.For instance, at the same electrical power, the pounds of the carburized hardened equipment will be about 1/3 of the excess weight of the tempered gear.Therefore, in line with the structural qualities of Planetary reduction drive and the strain nature of gears, hardtooth surface gears ought to be generally used.There are lots of heat treatment solutions to obtain gear with hard tooth surface, such as surface quenching, overall quenching, carburizing quenching, nitriding, etc., that ought to be selected according to the characteristics of Planetary decrease drive.
In Planetary reduction drive family, the Planetary reduction travel using its small size, great transmission efficiency, vast reduction range, high precision a large number of advantages, and is widely used in servo, stepping, dc and different tranny systems.Its function is in the premise of ensuring accuracy transmission, mainly used to reduce the rotation acceleration and increase torque and decrease the load/electric motor rotational inertia ratio.In order 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 at length how to properly install the Planetary reduction travel.
Appropriate installation, use and maintenance of of Planetary reduction travel is an important link to ensure the standard procedure of mechanical equipment.For that reason, 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 motor and Planetary reduction drive are intact before installation, and strictly check if the size of every part connected with the motor and Planetary reduction drive matches, this is actually the size of the positioning boss, input shaft and Planetary reduction travel 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, change the clamping ring of PCS system to align the side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, remove the motor shaft keys.

The hardness of tooth area can reach 45~55HRC.
Connection function between of Planetary reduction drive and servo motor: holding mode – output 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 lowering drive, the hoop can tighten the axis of the servo motor (the author has a 0.75KW servo electric motor with this connection). So for this connection function, servo motors usually do not require keyway (of training course, keyway may 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 electric motor: Connecting through external coupling. This connection mode uses external coupling, so it needs servo electric and keyway. External coupling can also use versatile coupling (flexible shaft) – gentle shaft drive electricity generally does not go beyond 5.5KW, speed can reach 20000 rpm. A kind of
Generally speaking, the servo motors without brakes and keyways will be the most used and the Ever-Power may be the largest. As a result, to purchase the servo motors with brakes and keyways, the delivery period is 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?
The noise of Planetary reduction drive is mainly caused by the friction, vibration and collision of the transmission gears. How to effectively reduce and reduce the noise to create it more in line with the requirements of environmental safety is also an integral research topic at home and abroad.Reducing the gear transmission noise of Planetary reduction drive has become an important research theme 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 dynamic load, vibration and noise.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 method, the process will need shape modification equipment, nearly all small factories often can not be implemented.
Planetary reduction drive is certainly a kind of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes 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 steering wheel to rotate on the helping axis.The planetary wheel, sunlight wheel and the apparatus ring are in continuous meshing state.
Located in the center of the planetary equipment transmission mechanism may be the sun wheel, sunlight wheel and the planet wheel often engage, two external equipment meshing rotation direction is normally opposite.Just as sunlight is at the guts of the solar program, the solar wheel is named because of its location.Gear band is the internal gear, it and the planet wheel often meshing, is the internal tooth and the outer gear meshing, the rotation direction between the two is the same.The quantity of planetary gear depends upon the design 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 equipment transmission structure of the key content.
Planetary speed of Planetary reduction drive can be a kind of speed of Planetary reduction drive, in that case, 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 wrong type collection causes insufficient end result torque of the Planetary decrease drive.
Some users in the unit selection, mistakenly as long as the selected rated end result torque Planetary reduction travel to meet the work requirements can be, in fact, it is not, one is the rated output torque of the motor rated output torque situations deceleration ratio, the worthiness obtained in principle should be less than the product sample to supply similar Planetary reduction travel rated output torque.The other is to consider the overload capacity of the drive engine and the maximum operating torque required in practice.
2. In the process 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 usually too frequent, that may eventually make Planetary reduction travel break the shaft.
Theoretically, the maximum operating torque required simply by an individual must be less than 2 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 and then 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 driving motor will still make it constantly boost the output force, which may cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque two times and so twist the output shaft of the Planetary reduction travel.
Precision planetary reduction drive
Product Description:
There are two main types based on the output direction: directly type and proper angle type; Planetary equipment systems are used to execute speed reduction due to huge torque. to predict equipment noise from a backside wheel drive automatic 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 greater than 10:1 and significantly 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);
In line with the purpose: army and civilian;Based on the operating environment: standard environment, low temp environment, clean bedroom 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-Power mountain drive you get additional very low gears which permit you proceed climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The first step is to confirm whether the engine and Planetary reduction travel are in good condition before installation, and strictly check whether the size of each part linked with the engine and Planetary reduction drive is matched. Here are the size and complementing tolerance of the positioning boss, insight shaft and Planetary decrease travel groove of the motor.
Step two 2: unscrew the screw on the outer dustproof hole of of Planetary reduction drive flange, adjust the clamping ring of PCS program to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.After that, take away the motor shaft keys.
The 3rd step is to connect the motor with Planetary reduction drive in a natural way.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 is not consistent, the electric motor shaft will be broken or of Planetary reduction drive gear wear.
In addition, in the installation, do not use hammer and different blows, prevent the axial force or radial force an excessive amount of harm to the bearing or gear.Make sure to tighten the installation bolt before tightening the push bolt.Before installation, wipe away the anti-corrosion oil of motor input shaft, positioning boss and connecting portion of of Planetary reduction drive with gasoline or zinc-sodium water.Its purpose is to make sure tight connection and flexibility of operation, and prevent unnecessary wear and tear.
Before the motor and Planetary decrease drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, initial screw the unit installation bolts at virtually any diagonal position, but do not screw limited, then screw the set up bolts at the various other two diagonal positions, and finally screw the four assembly bolts one at a time.Finally, tighten the force bolt.All tightening bolts will be fixed and checked by the torque plate hand according to the indicated torque data.
Appropriate installation between of Planetary reduction travel and mechanical tools is the same as correct installation between of Planetary reduction drive and drive motor.The key is to make certain 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 acceleration 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 travel can do more than 10000 nm. Working heat in 25 ℃ to 100 ℃ roughly, by changing the grease can transform its working temp.Planetary reduction travel: the key transmission structure is definitely: planetary wheel, solar wheel, outer gear ring.Weighed against additional reduction gear, servo electric motor reduction gear has large rigidity, high precision (one stage can achieve less than 1 point),(double stage can achieve less than 3 details), high transmission effectiveness (single stage in 95-99%), high torque/quantity ratio, life maintenance free features.Due to these characteristics, servo electric motor of Planetary reduction travel is mainly installed in the stepper motor and servo motor or brushless electric motor, used to lessen the speed, increase the torque, matching inertia.Rated input speed of servo motor of Planetary reduction travel can are as long as 18000rpm(related to how big is Planetary reduction travel itself.
