FIELD: engines and pumps. ^ SUBSTANCE: proposed method comprises heating the support bearing liner work surface layer and differs from known designs in that, to allow time and power savings, electric current is, first, passed through electric heaters built in under layer of every liner. Then liner electric heater power supply is cut off and, at the time, starting torque is applied. Invention comprises formula to determine time ä (s) of passing electric current through liner electric heater. Proposed device comprises metal layer of electric heater structure that is isolated all around by inorganic dielectric material laid under metal surface layer of every lines. Note that pair of faces of consecutively arranged liners are interconnected by common layer of electric heater metal. Note also that one of the liners comprises pin- or tape-type outer electric contact electrically connected with electric heater structure beginning, while the other liner has its electric heater end connected via inner pin terminal with liner metal base. At the same time, to use electric heater with different power in support plain bearing liner, every liner is furnished with inner pin and outer pin or tape terminals connected with liner electric heater beginning and end, respectively. Note that, to allow electric independence of electric heater of liner metal base, the liner is furnished with two pin or tape terminals electrically connected with electric heater structure beginning and end, respectively. Note also that work surface layer of such liner if provided with outer electrically insulated terminals connected with said layer. Invention covers a device design version. ^ EFFECT: higher time and power savings in starting cold engine. ^ 6 cl, 12 dwg |
