  • Analysis of bolt fracture causes - STARWDH

    1、 Bolt fracture is not due to tensile strength of bolt: Taking an M20 × 80 grade 8.8 high strength bolt as an example, its weight is only 0.2kg, and its minimum tensile load is 20t, which is up to 100000 times of its own weight. Under normal circumstances, we only use it to fasten 20kg parts, and only use one thousandth of its maximum capacity.

  • Why to say: the bolt does not loosen unceasingly, a ...

    2020-11-11 · The fracture of the bolt is not due to the fatigue strength of the bolt. In the transverse vibration loosening test, the threaded fastener can be loosened only 100 times, while in the fatigue strength test, it needs repeated vibration for one million times. In other words, the threaded fastener is loose when it uses one tenth of its fatigue strength.

  • Roth: Flexible jaw-type and bolt couplings

    Flexible jaw-type and bolt couplings compensate for non-uniform rotary movements. The use of torsionally flexible couplings reduces vibrations or impacts from one shaft to the other. They thereby guarantee power transmission whilst damping torsional vibrations and absorb shocks produced by the uneven operation of certain power machines.
