Abstract
Protective equipment is used in any equipment of motor vehicle enterprises, both to protect the equipment itself to reduce damage and for the worker. The protective elements of the equipment must provide high indicators of reliability and accuracy, therefore the purpose of this article is to conduct a study of these protective elements to improve their efficiency and reliability of operation when used on the equipment of motor vehicle enterprises. In the work, research on the design of protective couplings of various types, as well as experimental studies of the torque of the protective elements of these couplings. The places of use of these couplings were given with justification of their effectiveness and expediency in this equipment. Design schemes of these couplings are presented and the principles of their operation are described. Experimental studies of the torque depending on the design features of these couplings, calculations of the transmission of the maximum and minimum torque of the proposed protective couplings were carried out. Also, the experimental method was used to determine the indicators of the accuracy of operation due to the load on the protective elements of the proposed couplings, which showed good results. The proposed pulse-type coupling showed the possibility of load control without special design changes, which makes its use universal and effective in equipment. So, summing up, both experimental and theoretical studies can be concluded about the effectiveness of using these safety clutches in the equipment of motor vehicle enterprises. These protective clutches showed high indicators of accuracy and reliability of operation, which are confirmed by the results of research. Design features of the proposed protective couplings make their use universal, both for equipment with high load requirements and for mild loads, high accuracy of their operation makes them safe for workers.
