The article presents the ways of wide use of belt drives with variable and gear ratios in the drive mechanisms of technological machines. The scheme and principle of operation of the belt drive with composite driven pulleys and a tension roller are given, the necessary variable driving modes of the driven pulley are allowed. Analytical methods for determining the stiffness of the elastic elements of the driven pulley and tensioning roller are given . Based on the analysis of the plotted dependencies, the recommended values of the parameters of the considered belt drive for technological machine drives are substantiated. Production experiments and test results of the 1-CCC (Cotton Cleaning Complex) machine with the recommended belt drive justified the system parameters.

“…For example, the message of the working bodies of uneven rotation improves the quality of loosening and cleaning of fibrous material. For this purpose, belt drives with variable gear ratios [5] are used. Belt gears with variable gear ratio are used as an element of drives of various machines and mechanisms ensuring rotation of the driven shaft with variable angular speed: vibratory machines, machines for processing fibrous and bulk materials, mining and drilling machines, etc.…”

The article presents a constructive scheme and the principle of operation of the developed belt drive with a composite driven pulley with elastic elements. The technique and electrotsenometric scheme of the experimental setup for changing the loading and driving conditions of the recommended belt drive with composite driven pulleys with a rubber shock absorber are presented. The results of experimental studies on the loading of the shafts and the rotational speed of the transmission pulleys for various rubber grades used in composite pulleys are presented. The results of full-factor experiments to optimize the parameters of a belt drive, as well as the results of production tests of a cleaning machine, in the drive of which the recommended belt drive is used, are presented. Full-factor experiments substantiated the values of the rotational speed of the drum, the tension roller eccentricity and the stiffness coefficient of the elastic element, which provides a high cleaning effect.

“…A reliabilitybased optimal design method of V-belt drive was proposed by Gong et al [7] in which the number of the belt were adopted as the objective function and the system reliable as the constraint condition. Sun et al [8] provided a method for lifetime estimation of V-belt drive under different reliability level and numerical examples were given to validate the proposed method. Mazurkiewicz [9] pointed out that the system availability depended on a variety of factors including design, manufacturing, industrial diagnosis and maintenance.…”

Conventional reliability models of belt drive systems in the failure mode of fatigue are mainly based on the static stress strength interference model and its extended models, which cannot consider dynamic factors in the operational duration and be used for further availability analysis. In this paper, time-dependent reliability models, failure rate models and availability models of belt drive systems are developed based on the system dynamic equations with the dynamic stress and the material property degradation taken into account. In the proposed models, dynamic failure dependence and imperfect maintenance are taken into consideration. Furthermore, the issue of time scale inconsistency between system failure rate and system availability is proposed and addressed in the proposed system availability models. Besides, Monte Carlo simulations are carried out to validate the established models. The results from the proposed models and those from the Monte Carlo simulations show a consistency. Furthermore, the case studies show that the failure dependence, imperfect maintenance and the time scale inconsistency have significant influences on system availability. The independence assumption about the belt drive systems results in underestimations of both reliability and availability. Moreover, the neglect of the time scale inconsistency causes the underestimate of the system availability. Meanwhile, these influences show obvious time-dependent characteristics.
