Abstract
The paper aimed to use the old rubber tires which causing a big problem to the environment and its need much money and efforts to disposing it safely. In Iraq there is more than 2 million used tires disposed to the environment yearly whereas in the US there is 2 billion one. One of the tyre recycling methods , is the use of tyre plies to produce a new rubber parts used in the engineering and industrial purposes as the bridge and machine dampers , this trend of recycling doesn’t take a sufficient care comparing with the other methods . In the current research the study focusing on the mechanical properties of the used tyres and comparing them with the new one , and suggesting a new method to use the recycled tyres as an engineering parts ( for example the coupler lied between the IC engine and the generating head in the generators . One of the results obtained from the experiments, there is no significant difference between the mechanical properties of the old and new tyres , (in the tensile test – the breaking force of the tensile specimen of the new tyre is 137 N and for the old one is 113.27 N , but they are same in the elongation) . A dimensions of a flexible coupling suggested as a computational example and when using the experimental value of shear stress for the cord-rubber composite lamina (3.82*106N/m2)the calculation showing that the number of strips for the coupler should be two with 2 ply lamina or 4 with one ply lamina at engine power less than 30 Kw .
