1. | It was established that a compressed-stretched figured nut is preferred over a compressed cylindrical nut (the safety factors for stresses KN at the tie bolt thread root were 34 and 13, respectively). |
2. | In the figured nut, the last turn is maximally stressed and the average pressure on the side surface is 440 MPa. For reducing the load on the last turn with a view to increase the reliability of the joint, it is suggested that a bush be press fitted into the end part of the nut which is free of the thread. The calculation showed that this leads to redistribution of the load and a reduction in the pressure on the last turn to 390 MPa. |

The stress-strain state (SSS) of the lock joint in a dovetail-type compressor disk is investigated. The effect of type of loading and geometric parameters on the distribution of stress intensity is established. Surfaces of elastic-stress concentration are obtained as a function of the relationship between nominal stresses and the slope of the groove. It is demonstrated that consideration of torsion is a determining factor in performing SSS calculations for the real operating conditions of the type of lock joint under consideration.Translated from Problemy Prochnosti, No. 12, pp. 15–21, December, 1992. 相似文献

Methods are compared for calculating stress intensity coefficients in a three-dimensional elastic formulation. A method is proposed that uses approximation formulas that incorporate the crack geometry with stresses referred to a uniform distribution as acting at points on the crack front. A finite-element treatment gives the stress intensity distributions on the path of the supposed crack growth, which can be used to evaluate the effects from the geometry, loading conditions, and reinforcement of the actual structure. It also gives the decisive factor in calculating the stress intensity coefficients for real working conditions for a dovetail lock joint.Translated from Problemy Prochnosti, No. 2, pp. 65–70, February, 1993. 相似文献
