Full load efficiency: transmission efficiency of of Planetary decrease drive under maximum load (result torque of fault quit).
Working life: the cumulative working time of Planetary reduction drive in rated load and rated insight speed.
Rated torque: it is the torque that the rated life allows for long running time.When the output swiftness is 100 r/min, the life span of Planetary reduction drive is the average life, past this value, the common 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 generally proportional to the weight of the apparatus, and the weight of the gear includes a great relationship with the material and heat treatment hardness.For example, at the same power, the weight of the carburized hardened gear will be about 1/3 of the weight of the tempered equipment.Therefore, based on the structural features of Planetary reduction drive and the load nature of gears, hardtooth surface gears ought to be broadly used.There are many heat treatment methods 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 small size, high transmitting efficiency, wide reduction range, high precision many advantages, and is widely used in servo, stepping, dc and additional transmitting systems.Its function is in the premise of ensuring precision transmission, mainly used to reduce the rotation velocity and increase torque and decrease the load/motor rotational inertia ratio.To be able to help nearly all users to make good utilization 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 drive.
Right installation, use and maintenance of of Planetary reduction drive is certainly an important link to ensure the standard operation of mechanical equipment.Therefore, when you install the Planetary reduction drive, please be sure to strictly follow the following installation related matters, carefully assemble and use.
The first rung on the ladder is to confirm whether 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 matches, 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, modify 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 little gears) and flame quenching (for huge gears).The surface hardened layer works best 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 engine extends into of Planetary reduction drive, servo motor and Planetary reduction drive are linked by flange. There is a deformable hoop in Planetary decrease drive. By working the locking screw on Planetary reduction drive, the hoop can tighten the axis of the servo motor (the author has a 0.75KW servo motor with this connection). So for this connection mode, servo motors usually do not require keyway (of course, keyway may also be, but buying keyway servo motors requires Money and delivery period are longer yo @ @). Some sort of
Connecting mode of_of Planetary decrease drive and servo engine: Connecting through exterior coupling. This connection mode uses external coupling, so it needs servo electric and keyway. External coupling can also use flexible coupling (flexible shaft) – gentle shaft drive power generally does not go beyond 5.5KW, speed may reach 20000 rpm. Some sort of
In most cases, the servo motors without brakes and keyways are 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 usually longer, about 4 weeks.
Planetary reduction drive in the utilization 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 principally due to the friction, vibration and collision of the transmission gears. How to successfully reduce and decrease the noise to make it more good requirements of environmental safety is also an integral research topic at home and abroad.Reducing the gear transmission sound of Planetary reduction drive has become an important research topic in the industry. Many scholars in the home and abroad regard the change of equipment tooth engagement stiffness in gear transmission as the primary factor of gear powerful load, vibration and sound.By modifying the shape, the powerful load and velocity fluctuation are minimized to lessen the noise.This method has became more effective used.But with this technique, the process will need shape modification equipment, the majority of small factories often can not be implemented.
Planetary reduction drive is definitely some sort of of Planetary reduction drive, 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 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 continuous meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, the sun wheel and the planet wheel often engage, two external gear meshing rotation direction is usually opposite.Just as sunlight is at the center of the solar system, the solar wheel is named for its location.Gear ring is the internal gear, it and the planet wheel often meshing, may be the internal tooth and the outer gear meshing, the rotation direction between the two is the same.The amount of planetary gear depends upon the look load of the Planetary reduction drive, usually 3 or 4, the more the amount of bear the strain is greater.
The above is the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is definitely a kind of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive along the way of using the reason for the shaft break what?Let’s have a look.
1. The wrong type selection causes insufficient output torque of the Planetary reduction drive.
Some users in the model selection, mistakenly provided that the selected rated result torque Planetary decrease drive to meet the work requirements could be, in fact, it isn’t, one may be the rated output torque of the engine rated output torque situations deceleration ratio, the worthiness obtained in principle should be less than the merchandise sample to provide similar Planetary reduction drive rated result torque.The other is to consider the overload capacity of the drive engine and the utmost 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 ranked output torque, and such acceleration and deceleration is certainly too frequent, that may eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required by the user must be less than two times the rated output torque of the Planetary reduction drive, especially in a few 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 primary 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 generating motor will still make it constantly increase 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 decrease drive
Product Description:
There are two main types according to the output direction: straight type and right angle type; Planetary gear systems are accustomed to perform speed decrease due to huge torque. to predict gear noise from a back wheel drive automated transmission.
There are generally three types according to 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 general division principle is higher than 100:1);
According to the purpose: military and civilian;According to 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 gain additional very low gears which allow you go climb the the majority of extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
Planetary gear reduction drive
The first step is to confirm whether the engine and Planetary reduction drive are in good shape before installation, and strictly check whether the size of every part connected with the engine and Planetary reduction drive is matched. Listed below are the size and coordinating tolerance of the positioning boss, insight shaft and Planetary reduction drive groove of the motor.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary reduction drive flange, adjust 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 third step is to connect the engine 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 electric motor shaft will be broken or of Planetary decrease drive gear wear.
In addition, in the installation, do not use hammer and other 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 force 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 stop unnecessary wear and tear.
Planetary reduction drivePlanetary reduction drive
Prior to the motor and Planetary decrease drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To ensure a uniform force, first screw the installation bolts at any diagonal position, but usually do not screw tight, then screw the installation bolts at the various 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 checked by the torque plate hand based on the indicated torque data.
Right installation between of Planetary reduction drive and mechanical apparatus 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 engine of Planetary reduction drive Planetary reduction drive of Planetary reduction drive rated input increase to 18000 RPM (about of Planetary reduction drive itself size, the greater the swiftness of Planetary reduction drive, small the rated input swiftness) above, industrial-grade servo electric motor of Planetary
