Some Issues Concerning Gear Wheels Fabrication by Sintering
MetadatosMostrar el registro completo del ítem
Powder metallurgy appeared in the XVIII century as result of industrial market demand for electric bulbs filaments made of wolfram. Nowadays powder metallurgy is applied in such fields as: automotive industry (cylindrical or conical gear wheels), fine mechanics (components for calculation devices), toys production industry, electrical engineering (field poles for electrical fittings), machine building industry (filters, gear wheels, levers). In this work some applications of metallic powders in the fabrication of gear wheels are presented. As well the possibilities for their utilization in conical gear wheels of precessional planetary transmissions are described.
