Right installation, use and maintenance of of Planetary reduction drive is an important link to ensure the standard procedure of mechanical equipment.For that reason, when you install the Planetary reduction drive, make sure you be sure to strictly follow the following installation related matters, thoroughly assemble and use.
The first step is to confirm whether the engine and Planetary reduction travel are intact before installation, and strictly check whether the size of each part connected with the electric 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.

Connection mode between of Planetary decrease drive and servo electric motor: holding mode – end result shaft of servo electric motor extends into of Planetary reduction drive, servo motor and Planetary reduction travel are linked by flange. There exists a deformable hoop in Planetary lowering drive. By functioning the locking screw on Planetary reduction travel, the hoop can tighten the axis of the servo engine (the author includes a 0.75KW servo engine with this connection). And so for this connection function, servo motors do not require keyway (of training course, keyway may also be, but ordering keyway servo motors requires Money and delivery period 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 exterior coupling, so it needs servo electric and keyway. Exterior coupling can also use versatile coupling (flexible shaft) – very soft shaft drive ability generally does not surpass 5.5KW, speed may reach 20000 rpm. A kind of
Generally speaking, the servo motors without brakes and keyways will be the many used and the Ever-Power is the largest. For that reason, to buy the servo motors with brakes and keyways, the delivery period is much longer, about 4 weeks.
Planetary reduction drive 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 travel is mainly caused by the friction, vibration and collision of the transmission gears. How exactly to successfully reduce and decrease the noise to create it more based on the requirements of environmental proper protection is also an integral research topic at home and abroad.Reducing the apparatus transmission noises of Planetary reduction travel has become an important research theme in the industry. Many scholars at 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 powerful load and velocity fluctuation are minimized to lessen the noise.This technique has became more effective in practice.But with this technique, the process will need shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive can be a sort of of Planetary reduction travel, what’s the transmission structure of planetary gear?Let’s have a look.
A planetary gear carries a sun steering wheel, a planetary wheel, and a gear ring, wherein the planetary steering wheel is supported by a set axis of the planetary body, allowing the planetary steering wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the gear ring are in regular 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 usually opposite.Just as sunlight is at the center of the solar program, the solar wheel is known as because of its location.Gear band is the internal gear, it and the earth wheel often meshing, may be the inner tooth and the external gear meshing, the rotation direction between the two is the same.The number of planetary gear depends upon the look load of the Planetary reduction travel, usually three or four, the more the number of bear the load is greater.
The above may be the Planetary reduction drive gear transmission structure of the primary content.
Planetary speed of Planetary reduction drive is normally a kind of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive along the way of using the cause of the shaft break what?Let’s take a look.
1. The wrong type collection causes insufficient productivity torque of the Planetary lowering drive.
Some users in the model selection, mistakenly provided that the selected rated outcome torque Planetary reduction travel to meet the work requirements could be, in fact, it isn’t, one may be the rated productivity torque of the electric motor rated output torque situations deceleration ratio, the value obtained in principle ought to be less than the product sample to provide similar Planetary reduction drive rated productivity torque.The other is to consider the overload capacity of the drive motor and the maximum operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the result shaft of the Planetary reduction drive exceeds 2 times of its ranked output torque, and these kinds of acceleration and deceleration is too frequent, that may eventually make Planetary lowering travel break the shaft.
Theoretically, the utmost operating torque required simply by an individual must be significantly less than 2 times the rated output torque of the Planetary reduction drive, especially in some applications must strictly adhere to this criterion.This is simply not only to protect the Planetary reduction drive, but also to prevent 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 own load are stuck, the overload capacity of the driving a car motor will still make it constantly improve 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 travel.

Product Description:
There are two main types in line with the output direction: directly type and proper angle type; Planetary gear systems are used to perform speed reduction because of significant torque. to predict gear noise from a rear 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 greater than 10:1 and significantly less than or equal to 100:1), and three-stage deceleration (huge reduction ratio is 100) :1, the overall division principle is higher than 100:1);
According to the purpose: military and civilian;According to the operating environment: standard environment, low temperatures environment, clean bedroom environment and vacuum environment;

With the Ever-Electric power mountain drive you gain additional very low gears which allow you go climb the most extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The first 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 electric motor and Planetary reduction drive is matched. Listed below are the size and matching tolerance of the positioning boss, source shaft and Planetary reduction travel groove of the motor.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, change the clamping band of PCS system to align the medial side hole with the dustproof hole, insert the internal hexagon to tighten.From then on, take away the motor shaft keys.
The third step is to connect the electric motor with Planetary reduction travel by natural means.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the motor must be steady 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 lowering drive gear wear.
In addition, in the installation, usually do not use hammer and various other blows, avoid the axial force or radial force an excessive amount of damage to the bearing or gear.Make sure to tighten the installation bolt before tightening the pressure bolt.Before installation, wipe aside the anti-corrosion oil of motor input shaft, positioning boss and connecting component 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 deterioration.
Before the motor and Planetary decrease drive are linked, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, initially screw the unit installation bolts at any kind of 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 examined by the torque plate hand according to the indicated torque data.
Right installation between of Planetary reduction travel and mechanical products is equivalent to right installation between of Planetary reduction travel and drive engine.The main element is to make sure that the output shaft of Planetary reduction travel and the drive the main shaft concentricity.
