Full load efficiency: transmitting efficiency of of Planetary decrease drive under optimum load (result torque of fault prevent).
Working lifestyle: the cumulative working time of Planetary reduction drive at rated load and rated input speed.
Rated torque: it is the torque that the rated life allows for long term time.When the output swiftness is 100 r/min, the life span of Planetary reduction drive may be the average life, beyond this value, the average life of Planetary reduction drive will be reduced.Planetary reduction drive fails when the output torque exceeds twice.
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 apparatus, and the weight of the apparatus includes a great relationship with the materials and heat therapy 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, based on the structural characteristics of Planetary reduction drive and the load nature of gears, hardtooth surface gears ought to be broadly used.There are many 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.
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 various other tranny systems.Its function is in the premise of ensuring precision transmission, mainly used to lessen the rotation quickness and increase torque and reduce the load/motor rotational inertia ratio.In order to help nearly all users to create good usage of the Planetary reduction drive, this paper analyzes the causes of Planetary reduction drive and the drive motor shaft breaking, and introduces at length how exactly 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 operation of mechanical equipment.Consequently, when you install the Planetary reduction drive, please make certain to strictly follow the next installation related matters, properly assemble and use.
The first step is to confirm if the engine and Planetary reduction drive are intact before installation, and strictly check if the size of every part connected with the engine and Planetary reduction drive fits, this is actually the size of the positioning boss, input shaft and Planetary reduction drive groove of the electric motor and matching tolerance.
The next step is to unscrew the screw on the outer dustproof hole of Planetary reduction drive flange, modify 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.
Surface hardening editing
Common surface quenching methods are high-frequency quenching (for little gears) and flame quenching (for huge gears).The surface hardened layer is most effective 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 decrease drive and servo motor: holding mode – output shaft of servo engine extends into of Planetary reduction drive, servo engine and Planetary reduction drive are connected by flange. There exists a deformable hoop in Planetary reduction drive. By working the locking screw on Planetary decrease drive, the hoop can tighten the axis of the servo engine (the author has a 0.75KW servo electric motor with this connection). So for this connection mode, servo motors do not require keyway (of course, keyway may also be, but buying keyway servo motors needs Money and delivery time are longer yo @ @). A kind of
Linking mode of_of Planetary decrease drive and servo engine: Connecting through external coupling. This connection mode uses external coupling, so it needs servo electrical and keyway. Exterior coupling may also use flexible coupling (flexible shaft) – soft shaft drive power generally does not exceed 5.5KW, speed can reach 20000 rpm. Some sort of
In most cases, the servo motors without brakes and keyways will be the the majority of 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 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 to successfully reduce and reduce the noise to make it more based on the requirements of environmental protection is also a key research topic at home and abroad.Reducing the apparatus transmission sound of Planetary reduction drive has become an essential research subject in the industry. Many scholars in the home and abroad regard the change of equipment tooth engagement stiffness in equipment transmission as the main factor of gear dynamic load, vibration and noise.By modifying the form, the dynamic load and velocity fluctuation are minimized to reduce the noise.This technique has proved to be more effective used.But with this technique, 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 includes a sunlight wheel, a planetary wheel, and a gear ring, wherein the planetary wheel is supported by a set axis of the planetary frame, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, sunlight 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 planet wheel often engage, two external gear meshing rotation direction is opposite.Just as sunlight is at the guts of the solar program, the solar wheel is named for its location.Gear ring is the inner gear, it and the earth wheel often meshing, is the internal tooth and the external gear meshing, the rotation direction between the 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 amount of bear the load is greater.
The above is the Planetary reduction drive gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is definitely some sort of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive in the process of using the cause of 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 as long as the selected rated output torque Planetary reduction drive to meet up the work requirements could be, in fact, it is not, one is the rated result torque of the electric motor rated output torque moments deceleration ratio, the worthiness obtained in principle should 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 engine and the maximum operating torque required used.
2. Along the way of acceleration and deceleration, the instantaneous torque borne by the output shaft of the Planetary decrease drive exceeds two times of its rated output torque, and this kind of acceleration and deceleration is definitely too frequent, that will eventually make Planetary decrease drive break the shaft.
Theoretically, the utmost operating torque required simply 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 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 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 therefore twist the output shaft of the Planetary reduction drive.
Precision planetary decrease drive
Product Description:
There are two main types based on the output direction: directly type and correct angle type; Planetary equipment systems are used to perform speed decrease due to large torque. to predict gear noise from a back wheel drive automated transmission.
There are generally three types based on the number of stages: one-stage deceleration (generally 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 (huge reduction ratio is 100) :1, the overall division principle is higher than 100:1);
Based on the purpose: military and civilian;Based on the operating environment: regular 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 get additional suprisingly low gears which enable you go 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 electric motor and Planetary reduction drive are in good condition before installation, and strictly check whether the size of every part linked with the motor and Planetary reduction drive is matched. Here 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 decrease drive flange, adapt the clamping band of PCS program to align the medial side hole with the dustproof hole, insert the internal hexagon to tighten.From then on, remove the motor shaft keys.
The 3rd step is for connecting 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 constant when connected, and the outer flange of both must be parallel.If the concentricity is not consistent, the electric motor shaft will be broken or of Planetary decrease drive gear wear.
In addition, in the installation, usually do not use hammer and various other blows, avoid the axial force or radial force too much harm to the bearing or equipment.Make 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 ensure tight connection and flexibility of operation, and prevent unnecessary deterioration.
Planetary reduction drivePlanetary reduction drive
Before the motor and Planetary decrease drive are linked, the motor shaft keyway ought to be perpendicular to the tightening bolt.To ensure a uniform force, initial screw the installation bolts at any diagonal position, but do not screw limited, then screw the installation bolts at the additional two diagonal positions, and lastly 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 based on the indicated torque data.
Right installation between of Planetary reduction drive and mechanical gear is the same as correct installation between of Planetary reduction drive and drive motor.The main element is to make sure that the output shaft of Planetary reduction drive and the drive area of the shaft concentricity.
