Abstract

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.

Highlights

It is important to ensure uniform rotation of the output pulley associated with the working body of the technological machine [1,2,3,4]
The need for rotation of the driven shaft with a variable angular velocity is due to the fact that in some technological processes this leads to an increase in the effect of the operation of the machine
There is an alignment of the belt tension, leading to a uniform rotation of the pulleys of the belt drive

Summary

INTRODUCTION

It is important to ensure uniform rotation of the output pulley associated with the working body of the technological machine [1,2,3,4]. 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. During the execution of the technological process, the load on the shaft of the driven pulley 2 changes to the shaft of the machine and further on the leading pulley 1 and on the electric drive. In this case, the peak values of the moment of resistance (load) are depreciated by an annular elastic sleeve 7. Belt drive with integral driven pulley and eccentric elastic tension roller
