Аннотация
The issues connected with the prediction of mining machinery life are discussed. The basic index of reliability is an average life. The formulas are substantiated for calculating the average life of gear wheels, friction couple parts, shafts, and axles. The procedure proposed to estimate the life standard deviation is based on the method of linearization of functions of random variables. In this way, the life of standard parts of mining equipment can be found as random values with regard to operation conditions. Application of the procedure is exemplified by calculations of the life of a roller bearing. The calculation results are confirmed in the numerical experiment by the Monte Carlo method.
