What safety protection should be done during the rotation of the universal joint shaft?

Update:2021-08-20 00:00
Summary:

The universal joint shaft must be equipped with a complete and appropriate safety protection device during the rotation process. The purpose of this is to prevent the universal joint shaft from slipping and other accidents when it rotates. Once the accident occurs, the consequences are very serious, then the universal joint How should we do safety protection during the rotation of the shaft?

What safety protection should be done during the rotation of the universal joint shaft?

1. Cardan shafts are elastic and flexible. The strength of the flexible vibration and the critical bending speed must be carefully calculated. The maximum allowable speed must be completely lower than the critical bending speed provided when the first order is placed.
2. In order to ensure the safe and stable rotation of the universal joint shaft, it is forbidden to exceed the value range of the corresponding universal joint shaft size (speed × inclination).
3. To ensure the safe connection of the universal joint shaft, the surface of the universal joint shaft flange and the flange of the connected parts must be kept free of dust, oil and paint.
4. When installing the universal joint shaft, do not move the flange fork at will to avoid injury.
5. Check the position of the flange fork of the universal joint shaft, pay attention to its arrow mark, and it must be carefully calibrated, and it is forbidden to replace and change the spline at will.
6. Remove the transportation protection materials (such as baffles, etc.) before installation. If you have any doubts, please contact the supplier.
7. It is forbidden to use the installation lever to rotate the universal joint, so as not to damage the oil nozzle and the pressure reducing valve.
8. Use bolts and screws of specified material (strength). Use the bolts and screws required by the supplier. The bolts should be tightened symmetrically and evenly with a torque wrench.
9. When a fixed-length universal joint shaft is used, a connecting part of the universal joint shaft is elastically connected with the positioning pin of the flange, and the length compensation caused by the temperature change is adjusted by a suitable bearing adjustment device. Variety.

 

When using a telescopic universal joint shaft, the flange of the connected part must be firmly fixed on the universal joint shaft. If the storage period of the universal joint shaft exceeds 6 months, it should be relubricated before use. When spraying the universal joint shaft, be sure to confirm the sliding range of the seal ring.
