Connection mode between of Planetary lowering drive and servo motor: holding mode – result shaft of servo engine extends into of Planetary reduction drive, servo engine and Planetary reduction drive are connected by flange. You will find a deformable hoop in Planetary lowering drive. By working the locking screw on Planetary decrease travel, the hoop can tighten the axis of the servo electric motor (the author has a 0.75KW servo electric motor with this connection). Therefore for this connection setting, servo motors 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
Connecting mode of_of Planetary reduction drive and servo engine: Connecting through exterior coupling. This connection mode uses external coupling, so it needs servo electric and keyway. Exterior coupling may also use adaptable coupling (flexible shaft) – delicate shaft drive power generally does not go beyond 5.5KW, speed may reach 20000 rpm. Some sort of
Generally speaking, the servo motors without brakes and keyways will be the the majority of used and the Ever-Power may be the largest. For this reason, to buy the servo motors with brakes and keyways, the delivery period is for a longer time, about 4 weeks.
Planetary reduction drive in the utilization of the process you will see some noise, the emergence of the noise, how to deal with it?
The noise of Planetary reduction travel is mainly due to the friction, vibration and collision of the transmission gears. How to properly reduce and decrease the noise to make it more good requirements of environmental coverage is also a key research topic in the home and overseas.Reducing the gear transmission sound of Planetary reduction drive has become a crucial research theme in the market. Many scholars in the home and abroad respect the change of gear tooth engagement stiffness in equipment transmission as the key factor of gear powerful load, vibration and noise.By modifying the shape, the powerful load and velocity fluctuation are minimized to reduce the noise.This method has proved to be more effective in practice.But with this method, the process will need shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive is usually a kind of of Planetary reduction travel, 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 steering wheel is supported by a fixed axis of the planetary frame, allowing the planetary wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the gear ring are in frequent meshing state.
Located in the guts of the planetary gear transmission mechanism may be the sun wheel, sunlight wheel and the earth wheel frequently engage, two external gear meshing rotation direction is usually opposite.Just as the sun is at the guts of the solar program, the solar wheel is known as for its location.Gear ring is the inner gear, it and the earth wheel often meshing, is the inner tooth and the outer gear meshing, the rotation direction between the two is the same.The number of planetary gear is determined by the look load of the Planetary reduction drive, usually 3 or 4, the more the quantity of bear the load is greater.
The above may be the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive can be a kind of speed of Planetary reduction drive, then, the planetary speed of Planetary reduction drive in the process of using the reason for the shaft break what?Let’s take a look.
1. The wrong type variety causes insufficient result torque of the Planetary decrease drive.
Some users in the style selection, mistakenly provided that the selected rated productivity torque Planetary reduction drive to meet the work requirements could be, in fact, it isn’t, one may be the rated result 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 outcome 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 2 times of its rated output torque, and these kinds of acceleration and deceleration is usually too frequent, which will eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required by an individual 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 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 increase 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 thus twist the output shaft of the Planetary reduction travel.
Precision planetary reduction travel
Product Description:
There are two main types based on the output direction: straight type and correct angle type; Planetary equipment systems are used to perform speed reduction due to large torque. to predict equipment noise from a back wheel drive computerized 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 higher than 10:1 and 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: army and civilian;According to the operating environment: normal environment, low temperature environment, clean place environment and vacuum environment;

With the Ever-Power mountain drive you gain additional very low gears which permit you get climb the the majority of extreme torque Gears: 1:1 and 2.5:1 reduction gear ratio.
The initial step is to verify whether the engine and Planetary reduction drive are in good condition before installation, and strictly check whether the size of every part connected with the engine and Planetary reduction travel is matched. Listed below are the size and coordinating tolerance of the positioning boss, source shaft and Planetary decrease drive 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 band of PCS program to align the side hole with the dustproof hole, insert the interior hexagon to tighten.From then on, remove the motor shaft keys.
The third step is to hook up the motor with Planetary reduction drive the natural way.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be constant when connected, and the outer flange of both should be parallel.If the concentricity isn’t consistent, the engine shaft will be broken or of Planetary lowering drive gear wear.
Furthermore, in the installation, do not use hammer and various other blows, prevent the axial force or radial force too much 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 ensure tight connection and overall flexibility of operation, and prevent unnecessary wear and tear.
Before the motor and Planetary reduction drive are linked, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, primary screw the installation bolts at virtually any diagonal position, but usually do not screw restricted, then screw the set up bolts at the various other two diagonal positions, and lastly screw the four assembly 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.
Appropriate installation between of Planetary reduction drive and mechanical equipment is equivalent to accurate installation between of Planetary reduction drive and drive electric motor.The main element is to ensure that the output shaft of Planetary reduction drive and the drive portion of the shaft concentricity.
