| Abstract: | Conclusions The most effective method of prolonging the useful life of dry gear transmissions operating in a vacuum, carbon dioxide, or air is to use powdered lubricants and supply them by magnetic means to the rubbing zone. Use of magnetic powder lubricants enables toothed reduction gears to operate satisfactorily under Hertzian contact loads of up to 1100 MPa (11,000 kgf/cm2) at sliding speeds of up to 1.4 m/sec in the temperature range from –110 to +250°C.Translated from Poroshkovaya Metallurgiya, No. 10(214), pp. 61–65, October, 1980. |
