Design and Fabrication of Advanced Mechanical Tire Stretcher

A handheld advanced mechanical tire stretcher can be held between two sidewalls of the worn out tire and activated with circular feed to the handle wheel. A bevel gear pair is set to sequentially provide the required speed reduction, followed by development of torque needed to move the tire upper surface in vertical direction with clockwise direction rotation of the handle wheel. Also due to increase in pitch of power screw working get smoother than previous.  Thus the tire gets stretched in axial direction and compressed in radial direction. Thus tire can be placed in hot retreading mould. The principles embodied in the tire stretcher can be manually powered, or preferably motorized and possibly highly automated. With counter clockwise motion of handle wheel of tire stretcher; tire comes back to its original position
