There is a deformable hoop in Planetary lowering drive. By functioning the locking screw on Planetary reduction drive, the hoop can tighten the axis of the servo electric motor (the author includes a 0.75KW servo engine with this connection). Thus for this connection method, servo motors do not need keyway (of training, 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 electric motor: Connecting through external coupling. This connection mode uses external coupling, so that it needs servo electric and keyway. External coupling can also use versatile coupling (flexible shaft) – very soft shaft drive vitality generally does not surpass 5.5KW, speed can reach 20000 rpm. Some sort of
In most cases, the servo motors without brakes and keyways will be the most used and the Ever-Power may be the largest. For this reason, to order the servo motors with brakes and keyways, the delivery period is much longer, about 4 weeks.
Planetary reduction travel in the utilization of the process you will have some noise, the emergence of the noise, how 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 properly reduce and decrease the noise to create it more good requirements of environmental coverage is also an integral research topic at home and abroad.Reducing the gear transmission noises of Planetary reduction drive has become a crucial research theme in the industry. Many scholars in the home and abroad regard the change of gear tooth engagement stiffness in equipment transmission as the main factor of gear dynamic load, vibration and sound.By modifying the form, the dynamic load and velocity fluctuation are minimized to lessen the noise.This technique has proved to be more effective used.But with this technique, the process needs to have shape modification equipment, nearly all small factories often can not be implemented.
Planetary reduction drive is normally a sort of of Planetary reduction drive, what’s the transmission structure of planetary gear?Let’s take a look.
A planetary gear includes a sun wheel, a planetary wheel, and a gear band, wherein the planetary wheel is supported by a set axis of the planetary framework, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the gear ring are in regular meshing state.
Located in the center of the planetary equipment transmission mechanism is the sun wheel, sunlight wheel and the earth wheel typically 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 earth wheel often meshing, may be the inner tooth and the outer gear meshing, the rotation direction between your two is the same.The number of planetary gear depends upon the design load of the Planetary reduction drive, usually three or four, the more the quantity of bear the load is greater.
The above may be the Planetary reduction travel gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is certainly 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 take a look.
1. The wrong type assortment causes insufficient productivity torque of the Planetary lowering drive.
Some users in the style selection, mistakenly provided that the selected rated productivity torque Planetary reduction drive to meet up the work requirements can be, in fact, it isn’t, one is the rated outcome torque of the motor rated output torque instances deceleration ratio, the value obtained in principle ought to 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 electric motor and the utmost operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the end result shaft of the Planetary lowering drive exceeds two times of its ranked output torque, and this kind of acceleration and deceleration is usually too frequent, that will eventually make Planetary lowering travel break the shaft.
Theoretically, the utmost operating torque required by the user must be significantly less than two 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 prevent the output shaft of Planetary reduction drive from being twisted off.The main reason is that, when there is a problem in equipment installation, the output shaft of the Planetary reduction travel and its load are stuck, the overload capacity of the generating motor will still make it constantly raise the output force, which may cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque 2 times and so twist the output shaft of the Planetary reduction drive.
Precision planetary reduction travel
Product Description:
There are two main types in line with the output direction: right type and correct angle type; Planetary equipment systems are used to execute speed reduction due to significant torque. to predict equipment noise from a back wheel drive programmed transmission.
There are generally three types according to 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);
Based on the purpose: armed service and civilian;Based on the operating environment: common environment, low heat environment, clean place environment and vacuum environment;

With the Ever-Power mountain drive you get additional very low gears which enable you go climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to verify whether the motor and Planetary reduction drive are in good condition before installation, and strictly check if the size of each part linked with the motor and Planetary reduction travel is matched. Listed below are the size and matching tolerance of the positioning boss, suggestions shaft and Planetary reduction travel groove of the electric motor.
Step two 2: unscrew the screw on the external dustproof hole of of Planetary lowering drive flange, modify the clamping ring of PCS program to align the 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 hook up the electric motor with Planetary reduction drive by natural means.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the motor must be regular when connected, and the external flange of the two should be parallel.If the concentricity isn’t consistent, the motor shaft will be broken or of Planetary reduction drive gear wear.
Furthermore, in the installation, usually do not use hammer and various other blows, prevent the axial force or radial force an excessive amount of damage to the bearing or equipment.Make sure you 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 make sure tight connection and flexibility of operation, and prevent unnecessary wear and tear.
Prior to the motor and Planetary decrease drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, initially screw the assembly bolts at any kind of diagonal position, but do not screw limited, then screw the assembly bolts at the various other two diagonal positions, and finally screw the four unit installation bolts one at a time.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 travel and mechanical equipment is the same as correct installation between of Planetary reduction drive and drive electric motor.The main element is to make certain that the output shaft of Planetary reduction drive and the drive portion of the shaft concentricity.
