In order to better help customers with good planetary reducer, reducer and drive motor off axis reason analysis, and a detailed description of how to properly install a planetary reducer broken shaft. Some users drive device running a few months after the output shaft of the reducer is broken. Why the gear unit output shaft of the driving motor wring? To this end, we view the cross-section of the output shaft of the drive motor, with almost exactly the same cross-section of the output shaft of the reducer. Cross-section of the outer ring is brighter, and more to the axis at the cross-section, the darker the color, and finally to the axis is broken at the! This fully explains the main reason for the output shaft of the drive motor is broken shaft motor and reducer assembly Heart! Concentricity between the motor and reducer assembly to ensure a very good the motor output bearings by just turning force operation will be very smooth. Different mind, however, the output shaft to withstand the radial force of the reducer from the input terminal, the long-term effect of the radial force will cause the motor output shaft is forced to bend, and the direction of bending is changing with the rotation of the output shaft. Per revolution of the output axis, the lateral force of the direction change of 360 degrees. Concentricity error is large, the radial force to make the temperature of the motor output shaft increases, the metal structure is constantly being destroyed, and finally, the radial force will exceed the motor output shaft can withstand the radial force, and finally lead to drive The motor output shaft is broken. The shorter the time, the drive motor output shaft broken when the greater the concentricity error. Broken while in the output shaft of the drive motor, the gear unit input terminal will also withstand the radial force from the motor, if the radial force at the same time exceeds the maximum radial load can withstand both, then its result will resulting in the reducer input of deformation or fracture. Therefore, in the assembly to ensure concentricity is critical! Intuitively, if the concentric to the motor shaft and gear unit input terminal, then the fit between the motor and reducer will be very close, the contact surface between them is closely connected, and the assembly when the heart, then the contact surface between them between there will be a gap. The left of Figure 3 shows the assembly between the motor and reducer is very good, and illustrates the assembly is not good, the motor shaft and reducer broken shaft. Taking into account the more this happens, it is further introduction.
The correct planetary reducer installation and maintenance reducer, is an important part of ensuring the normal operation of mechanical equipment. You install NEUGART planetary reducer sure in strict accordance with the following installation related matters seriously assembly and use. The first step is recognized before installing motor and reducer are intact, and strictly check whether the size of the various parts of the matching motor and reducer connected, here is the positioning of the motor boss, the size and fit of the input shaft with reducer groove. tolerances. The second step is to unscrew the reducer flange on the outside dust-hole screw clamping ring to its side of the hole and the dust-hole alignment, adjust the PCS system, insert Hexagon tighten. After removal of the motor shaft key. The third step is naturally connected to the motor and reducer. Must ensure that the output shaft of the reducer and motor input shaft concentricity consistent, and both the outside flange parallel connection. As inconsistent centrality, will lead to the break of the motor shaft reducer gear wear. In addition, when installed, it is strictly prohibited to use hammers and other hits, to prevent the axial force, radial force excessive damage to the bearing or gear Be sure to install the bolts tightened and then screwed tightly to force the bolt. Before installation, the motor input shaft positioning bosses and anti-rust oil reducer joints wipe net sodium and water use gasoline or zinc. Its purpose is to ensure that the connection tightness and operation flexibility, and to prevent unnecessary wear. Before connecting the motor and reducer, please the vertical keyway of the motor shaft tensioning bolts. Force uniform, please any mounting bolts spin angular position, but do not tighten the spin on the last one by one of two pairs of the angular position of the mounting bolts tighten the four mounting bolts. Finally, the spin tightly force the bolt. All tensioning bolts are required to use a torque wrench fixed torsional moment data indicated fixed and inspected. The right-angle gearhead related data with the same model straight reducer is not exactly the same, also requested the user's attention. Reducer with mechanical equipment installed correctly similar reducer drive motor is installed correctly. The key must ensure reducer output shaft driven shaft concentricity.
I hope in the future planetary reducer attention to the correct way to use, in order to avoid unnecessary trouble. |
