What safety protection should be done during cardan shaft rotation?

The cardan shaft rotation process must be equipped with a complete and appropriate safety protection device, the purpose of doing so is to prevent the cardan shaft in the rotation of accidents such as slipping, once the unexpected consequences are very serious, then the cardan shaft rotation process how should we do a good job of safety protection?



What safety protection should be done during cardan shaft rotation?

1, the universal shaft has elasticity and flexibility, must carefully calculate the strength of its flexible vibration and critical bending speed, its maximum allowable speed must be completely lower than the critical bending speed provided when the first order.
2, in order to ensure the safe and smooth rotation of the cardan shaft, it is prohibited to exceed the value range of the corresponding cardan shaft size (speed × inclination).
3, to ensure the safe connection of the cardan shaft, it is necessary to keep the surface of the cardan shaft flange and the connected part flange free of dust, oil and paint.
4, when installing the cardan shaft, can not move the flange fork at will to avoid injury.
5, check the position of the flange head of the cardam shaft, pay attention to its arrow mark, it must be carefully calibrated, and it is prohibited to replace and change the spline at will.
6, remove the transport protection materials (such as baffles, etc.) before installation, if there is any doubt, please contact the supplier.
7, do not use the installation lever to turn the universal joint, so as not to damage the nozzle and pressure reducing valve.
8. Use bolts and screws of specified material (strength). Use bolts and screws as required by the supplier. Bolts should be tightened symmetrically and evenly with torque wrench.
9. When using a fixed-length cardan shaft, one of the connecting parts of the cardan shaft is connected with the positioning pin of the flange by the elastic, and the change of the length compensation caused by the temperature change is adjusted by the appropriate bearing adjustment device.
When the telescopic cardan shaft is used, the flange of the connected piece must be firmly fixed on the cardan shaft. If the cardan shaft is stored for more than 6 months, it should be re-lubricated before use. When spraying the cardan shaft, be sure to confirm the sliding range of the seal ring.
