The hardness of tooth area can reach 45~55HRC.
Connection method between of Planetary reduction drive and servo motor: holding mode – outcome shaft of servo electric motor extends into of Planetary decrease drive, servo engine and Planetary reduction travel are connected by flange. There exists a deformable hoop in Planetary lowering drive. By operating the locking screw on Planetary lowering drive, the hoop can tighten the axis of the servo electric motor (the author has a 0.75KW servo electric motor with this connection). Hence for this connection method, servo motors do not need keyway (of program, keyway may also be, but ordering keyway servo motors requires Money and delivery time are longer yo @ @). A kind of
Linking mode of_of Planetary reduction drive and servo motor: Connecting through external coupling. This connection setting uses exterior coupling, so that it needs servo electric and keyway. External coupling may also use flexible coupling (flexible shaft) – gentle shaft drive electricity 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 buy the servo motors with brakes and keyways, the delivery period is longer, about 4 weeks.
Planetary reduction travel in the use of the process there will be some noise, the emergence of the noise, how exactly 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 reduce the noise to make it more in line with the requirements of environmental proper protection is also a key research topic at home and overseas.Reducing the gear transmission sound of Planetary reduction drive has become an important research issue in the market. Many scholars at home and abroad regard the change of equipment tooth engagement stiffness in gear transmission as the primary factor of gear dynamic load, vibration and noises.By modifying the shape, the dynamic load and velocity fluctuation are minimized to reduce the noise.This technique has became more effective in practice.But with this method, the process will need shape modification equipment, the majority of small factories often can not be implemented.
Planetary reduction drive can be a sort of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sun steering wheel, a planetary steering wheel, and a gear ring, wherein the planetary steering wheel is supported by a fixed axis of the planetary body, allowing the planetary wheel to rotate on the assisting axis.The planetary wheel, sunlight wheel and the apparatus ring are in regular meshing state.
Located in the center of the planetary gear transmission mechanism is the sun wheel, the sun wheel and the planet wheel often engage, two external equipment meshing rotation direction is opposite.Just as sunlight is at the center of the solar program, the solar wheel is named for its location.Gear ring is the inner gear, it and the earth wheel often meshing, is the interior tooth and the outer gear meshing, the rotation direction between the two is the same.The amount of planetary gear depends upon the design load of the Planetary reduction drive, usually 3 or 4, the more the number of bear the load is greater.
The above is the Planetary reduction travel gear transmission structure of the key content.
Planetary speed of Planetary reduction drive is a kind of speed of Planetary reduction drive, in that case, 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 reduction drive.
Some users in the model selection, mistakenly provided that the selected rated end result torque Planetary reduction travel to meet the work requirements could be, in fact, it isn’t, one may be the rated output torque of the motor rated output torque instances deceleration ratio, the worthiness obtained in principle ought to be less than the product sample to provide similar Planetary reduction drive rated outcome torque.The other is to consider the overload capacity of the drive electric motor and the maximum operating torque required used.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the productivity shaft of the Planetary lowering drive exceeds 2 times of its ranked output torque, and these kinds of acceleration and deceleration can be too frequent, that may eventually make Planetary decrease drive break the shaft.
Theoretically, the maximum operating torque required simply by the user must be less than 2 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 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 drive and its load are stuck, the overload capacity of the travelling motor will still make it constantly boost the output force, which might cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque two times and therefore twist the output shaft of the Planetary reduction travel.

Step two 2: unscrew the screw on the external dustproof hole of of Planetary reduction drive flange, modify the clamping ring of PCS system to align the medial 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 connect the motor with Planetary reduction travel in a natural way.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the engine must be regular when connected, and the outer flange of the two should be parallel.If the concentricity is not consistent, the electric motor shaft will be broken or of Planetary decrease drive gear wear.
Furthermore, in the installation, do not use hammer and various other blows, avoid the axial force or radial force an excessive amount of damage to the bearing or equipment.Be sure to tighten the installation bolt before tightening the pressure bolt.Before installation, wipe away 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 purpose is to ensure tight connection and flexibility of operation, and stop unnecessary deterioration.
Prior to the motor and Planetary reduction drive are connected, the motor shaft keyway ought to be perpendicular to the tightening bolt.To ensure a uniform force, initial screw the unit installation bolts at any kind of diagonal position, but do not screw restricted, then screw the assembly bolts at the different two diagonal positions, and finally screw the four unit installation bolts one at a time.Finally, tighten the force bolt.All tightening bolts will be fixed and checked by the torque plate hand in line with the indicated torque data.
Accurate installation between of Planetary reduction drive and mechanical apparatus is equivalent to accurate installation between of Planetary reduction drive and drive electric motor.The key is to make sure that the output shaft of Planetary reduction drive and the drive the main shaft concentricity.
