Connection method between of Planetary decrease drive and servo engine: holding mode – end result shaft of servo motor extends into of Planetary decrease drive, servo engine and Planetary reduction travel are linked by flange. You will find a deformable hoop in Planetary decrease drive. By operating the locking screw on Planetary decrease drive, the hoop can tighten the axis of the servo electric motor (the author includes a 0.75KW servo engine with this connection). So for this connection function, servo motors usually do not need keyway (of course, keyway may also be, but buying keyway servo motors needs Money and delivery time are longer yo @ @). Some sort of
Connecting mode of_of Planetary reduction drive and servo electric motor: Connecting through external coupling. This connection function uses external coupling, so that it needs servo electric and keyway. Exterior coupling may also use versatile coupling (flexible shaft) – soft shaft drive vitality generally does not surpass 5.5KW, speed may reach 20000 rpm. A kind of
Generally speaking, the servo motors without brakes and keyways are 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 longer, 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 drive is mainly due to the friction, vibration and collision of the transmission gears. How to efficiently 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 noises of Planetary reduction travel has become an essential research issue in the market. Many scholars in the home and abroad regard the change of gear tooth engagement stiffness in equipment 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 method, the process needs to have shape modification equipment, nearly all small factories often can not be implemented.
Planetary reduction drive can be a sort of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have 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 body, allowing the planetary wheel to rotate on the helping axis.The planetary wheel, the sun 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 earth wheel sometimes engage, two external gear meshing rotation direction is definitely opposite.Just as the sun is at the guts of the solar system, the solar wheel is known as for its location.Gear band is the inner gear, it and the planet wheel often meshing, may be the interior tooth and the external gear meshing, the rotation direction between the two is the same.The number of planetary gear depends on the design 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 travel gear transmission structure of the main content.
Planetary speed of Planetary reduction drive is a sort of speed of Planetary reduction drive, after that, the planetary speed of Planetary reduction drive in the process 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 decrease drive.
Some users in the model selection, mistakenly as long as the selected rated result torque Planetary reduction travel to meet the work requirements can be, in fact, it isn’t, one may be the rated end result torque of the engine rated output torque circumstances deceleration ratio, the value obtained in principle ought to be less than the product sample to supply similar Planetary reduction drive rated end result torque.The other is to consider the overload capacity of the drive motor 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 lowering drive exceeds 2 times of its ranked output torque, and this sort of acceleration and deceleration is certainly too frequent, that will eventually make Planetary reduction drive break the shaft.
Theoretically, the utmost operating torque required simply 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 adhere to 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 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 boost the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque 2 times and thus twist the output shaft of the Planetary reduction travel.
Precision planetary reduction drive
Product Description:
There are two main types according to the output direction: directly type and correct angle type; Planetary gear systems are used to perform speed reduction because of huge torque. to predict equipment noise from a back wheel drive programmed transmission.
There are generally three types in line with the number of stages: one-stage deceleration (generally significantly less than 10:1), two-stage deceleration (generally greater than 10:1 and significantly less than or add up to 100:1), and three-stage deceleration (huge reduction ratio is 100) :1, the general division principle is greater than 100:1);
In line with the purpose: army and civilian;In line with the operating environment: standard environment, low temp 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 Ever-Power mountain drive you gain additional suprisingly low gears which allow you move 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 motor and Planetary reduction drive are in good shape before installation, and strictly check whether the size of each part connected with the motor and Planetary reduction travel is matched. Listed below are the size and matching tolerance of the positioning boss, input shaft and Planetary decrease drive groove of the electric motor.
Step 2 2: unscrew the screw on the external dustproof hole of of Planetary lowering drive flange, change the clamping ring of PCS program to align the medial side hole with the dustproof hole, insert the interior hexagon to tighten.From then on, take away the motor shaft keys.
The 3rd step is to hook up the engine with Planetary reduction travel naturally.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be steady when connected, and the external flange of both should be parallel.If the concentricity is not consistent, the engine 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 harm to the bearing or equipment.Be sure to tighten the installation bolt ahead of tightening the power bolt.Before installation, wipe away the anti-corrosion 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 make sure tight connection and versatility of operation, preventing unnecessary wear and tear.
Prior to 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, first screw the assembly bolts at any kind of diagonal position, but usually do not screw tight, then screw the installation bolts at the 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 checked by the torque plate hand according to the indicated torque data.
Appropriate installation between of Planetary reduction travel and mechanical equipment is the same as accurate installation between of Planetary reduction drive and drive motor.The key is to ensure that the output shaft of Planetary reduction travel and the drive part of the shaft concentricity.
