Planetary reduction drive is definitely a kind of of Planetary reduction travel, what is the transmission structure of planetary gear?Let’s take a look.
A planetary gear carries a sun wheel, a planetary steering wheel, and a gear ring, wherein the planetary wheel is supported by a fixed axis of the planetary framework, allowing the planetary steering wheel to rotate on the supporting axis.The planetary wheel, the sun wheel and the apparatus ring are in regular meshing state.
Located in the center 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 center of the solar system, the solar wheel is named for its location.Gear band is the inner gear, it and the planet wheel often meshing, is the inner tooth and the outer gear meshing, the rotation direction between the two may be the same.The number 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 load is greater.
The above is the Planetary reduction drive equipment transmission structure of the main content.
Planetary speed of Planetary reduction drive is usually a kind of speed of Planetary reduction drive, then, the planetary speed of Planetary reduction drive along the way of using the reason for the shaft break what?Let’s have a look.
1. The wrong type variety causes insufficient productivity torque of the Planetary decrease drive.
Some users in the version selection, mistakenly so long as the selected rated end result torque Planetary reduction drive to meet the work requirements can be, in fact, it is not, one is the rated productivity torque of the engine rated output torque situations 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 in practice.
2. In the process of acceleration and deceleration, the instantaneous torque borne by the outcome shaft of the Planetary lowering drive exceeds two times of its ranked output torque, and such acceleration and deceleration is usually too frequent, which will eventually make Planetary decrease travel break the shaft.
Theoretically, the utmost operating torque required simply by an individual must be 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 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, when 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 generating motor will still make it constantly increase the output force, which might cause the force of the output bearing of the Planetary reduction travel to exceed its rated output torque 2 times and so twist the output shaft of the Planetary reduction travel.

Step 2 2: unscrew the screw on the outer dustproof hole of of Planetary decrease drive flange, adapt the clamping band of PCS program to align the medial side hole with the dustproof hole, insert the inner hexagon to tighten.From then on, remove the motor shaft keys.
The third step is to hook up the electric motor with Planetary reduction drive by natural means.The concentricity of the output shaft of Planetary reduction travel and the input shaft of the motor must be constant when connected, and the external flange of both should be parallel.If the concentricity is not consistent, the electric motor shaft will be broken or of Planetary decrease 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 harm to the bearing or gear.Make sure you tighten the installation bolt ahead of tightening the force bolt.Before installation, wipe away 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 purpose is to ensure tight connection and flexibility of operation, and stop unnecessary deterioration.
Before the motor and Planetary decrease drive are connected, the motor shaft keyway should be perpendicular to the tightening bolt.To make sure a uniform force, initially screw the set up bolts at any diagonal position, but usually do not screw limited, then screw the set up bolts at the various other two diagonal positions, and finally screw the four installation bolts one by one.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 apparatus is equivalent to accurate installation between of Planetary reduction travel and drive motor.The key is to ensure that the output shaft of Planetary reduction drive and the drive area of the shaft concentricity.
