摘要：
In this paper, a method for testing of gearwheels for automotive gear boxes manufactured using the methods of powder metallurgy is presented, and the results obtained by this way are given. The methods of powder metallurgy comprise powder formation, forming, sintering, secondary pressing and heat treatment of gearwheels for automotive gearboxes. This modern technology presents opportunity for saving material and energy for the production of gearwheels, increase of productivity and reducing the net costs of the goods. Using this technology, a number of gearwheels were produced, which were used in automotive transmissions. The tests for fatigue and wear were done on a special re-fabricated test bench operating on recirculation power scheme. Afterwards the gearbox with the tested gearwheel was mounted on an automotive for road tests. The analysis of the results shows that the gearwheels produced by the technology of powder metallurgy can be used in automotive gearboxes.
