Mechanisms for increasing the strength of butt joints of rubber cord ropes and belts
Abstract
In the article to reveal the mechanisms of increasing the strength of butt joints of rubber cord ropes and belts. The types of connections of rubber cord ropes and belts are described. The analysis of the advantages and disadvantages of each type of connection is carried out. Mechanisms for increasing the strength of butt joints of rubber-cord ropes and belts are proposed, and an approach to each mechanism is substantiated. A schematic representation of a joint without edge delamination and wedge joints. A formula is proposed for determining the strength level of butt joints of rubber cord ropes and tapes, where the main indicator is the strength levels and the quality of the tape and the joint, which depends on the level of the pulling force of the cable from the rubber. A numerical analysis of the strength of the joints of rubber cord ropes and belts, depending on the quality of their manufacture, is carried out, and the concept of squidge and the dependence of the pulling force of a cable from rubber on its thickness are disclosed. In the variant of improving the quality of the joints of rubber cord ropes and belts through the use of thickened rubber, the numerical value of the strength of the joints of rubber cord ropes and belts is disclosed.
