<p>An arrangement for reinforcing a thread connected shaft under dynamic load in which a threaded coupling is fitted over the shaft and the coupling components are turned with respect to each other to lengthen the coupling and press against abutments at the ends of the portions of the shaft to be reinforced. In this way there is applied to the portion of the shaft being reinforced a tensile load at least as great as the maximum external load to be applied to the shaft.</p> |
