Tiivistelmä
Tire regrooving is a technology for reusing tires. This technology provides benefits in the form of extending the life of the tire, as well as in the form of reducing the vehicle's fuel consumption.
Tire regrooving is currently done manually. Manual regrooving involves the use of a sharp, heated tool with which channels are deepened on the existing tire tread layer. The manual process of regrooving tires requires moving the tool by the operator. The quality of the manual regrooving process depends on the readiness and skill of the operator, and as such is subject to human-made mistakes.
In this thesis an automated tire regrooving machine was designed and built. The machine was tested and the results showed that a more precise tread pattern and less deviation from the desired pattern are achieved, with operating cost reduced by up to one-fifth of the manual regrooving process cost due to the tested machine capacity. In addition, the automated regrooving process enhanced the operator safety in comparison with manual regrooving.
This thesis assessed the impact of automated tire regrooving and fuel consumption reduction on the environment. Automated tire regrooving is beneficial for the user of the machine due to the lower operational cost and reduced consumption, but also for the environment due to the reduced environmental impact (reduced fuel consumption) of the vehicles with regrooved tires. Up to 400 kg of fuel can be saved on a 5-axle truck which uses regrooved tires.
