Connection setting between of Planetary decrease drive and servo motor: holding mode – output shaft of servo motor extends into of Planetary decrease drive, servo motor and Planetary reduction travel are connected by flange. There exists a deformable hoop in Planetary lowering drive. By operating the locking screw on Planetary reduction travel, the hoop can tighten the axis of the servo engine (the author includes a 0.75KW servo electric motor with this connection). Consequently for this connection method, servo motors usually do not require keyway (of study course, keyway can also be, but purchasing keyway servo motors requires Money and delivery period are longer yo @ @). Some sort of
Linking mode of_of Planetary decrease drive and servo motor: Connecting through external coupling. This connection setting uses exterior coupling, so that it needs servo electrical and keyway. External coupling may also use adaptable coupling (flexible shaft) – delicate shaft drive electrical power generally does not surpass 5.5KW, speed may reach 20000 rpm. Some sort of
Generally speaking, the servo motors without brakes and keyways will be the most used and the Ever-Power is the largest. For that reason, to purchase the servo motors with brakes and keyways, the delivery period is for a longer time, about 4 weeks.
Planetary reduction drive 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 create it more in line with the requirements of environmental protection is also a key research topic at home and overseas.Reducing the apparatus transmission noise of Planetary reduction drive has become an essential 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 powerful load, vibration and noise.By modifying the form, the dynamic load and velocity fluctuation are minimized to reduce the noise.This method has proved to be more effective used.But with this technique, the process will need shape modification equipment, the majority of small factories often can’t be implemented.
Planetary reduction drive is certainly a kind of of Planetary reduction drive, what is the transmission structure of planetary gear?Let’s have a look.
A planetary gear includes a sun steering wheel, a planetary steering wheel, and a gear ring, wherein the planetary steering wheel is supported by a set axis of the planetary framework, allowing the planetary steering 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 center of the planetary equipment transmission mechanism may be the sun wheel, the sun wheel and the planet wheel typically engage, two external gear meshing rotation direction is definitely opposite.Just as the sun is at the guts of the solar program, the solar wheel is named because of its location.Gear ring is the interior gear, it and the planet wheel often meshing, is the internal tooth and the outer gear meshing, the rotation direction between the two is the same.The amount of planetary gear will depend on the look load of the Planetary reduction drive, usually three or four, the more the amount of bear the strain is greater.
The above is the Planetary reduction travel equipment transmission structure of the primary content.
Planetary speed of Planetary reduction drive is usually 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 selection causes insufficient output torque of the Planetary reduction drive.
Some users in the model selection, mistakenly given that the selected rated output torque Planetary reduction drive to meet up the work requirements can be, in fact, it is not, one is the rated output torque of the motor rated output torque times deceleration ratio, the value obtained in principle should be less than the merchandise sample to supply similar Planetary reduction drive rated output 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 end result shaft of the Planetary reduction drive exceeds 2 times of its ranked output torque, and this sort of acceleration and deceleration is definitely too frequent, that may eventually make Planetary lowering drive break the shaft.
Theoretically, the utmost operating torque required by an individual must be less than 2 times the rated output torque of the Planetary reduction drive, especially in some applications must strictly comply with this criterion.This is 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 travel and its own load are stuck, the overload capacity of the driving a vehicle motor will still make it constantly improve the output force, which may cause the force of the output bearing of the Planetary reduction drive to exceed its rated output torque two times and so twist the output shaft of the Planetary reduction travel.

Here are the size and coordinating tolerance of the positioning boss, input shaft and Planetary reduction travel groove of the engine.
Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary lowering drive flange, modify the clamping ring of PCS program to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.After that, remove the motor shaft keys.
The third step is to hook up the motor with Planetary reduction drive normally.The concentricity of the output shaft of Planetary reduction drive and the input shaft of the motor must be regular when connected, and the outer flange of both should be parallel.If the concentricity is not consistent, the motor shaft will be broken or of Planetary lowering drive gear wear.
Furthermore, in the installation, usually do not use hammer and different blows, avoid the axial force or radial force an excessive amount of harm to the bearing or gear.Make sure to tighten the mounting bolt prior to tightening the push bolt.Before installation, wipe apart the anti-corrosion 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 ensure tight connection and versatility of operation, and prevent unnecessary deterioration.
Prior to the motor and Planetary lowering drive are connected, the motor shaft keyway ought to be perpendicular to the tightening bolt.To make sure a uniform force, primary screw the installation bolts at any kind of diagonal position, but usually do not screw limited, then screw the set up bolts at the different two diagonal positions, and finally screw the four set up 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.
Appropriate installation between of Planetary reduction drive and mechanical tools is equivalent to appropriate installation between of Planetary reduction drive and drive electric motor.The key is to make certain that the output shaft of Planetary reduction drive and the drive part of the shaft concentricity.
