Abstract: The invention relates to a thermally insulated Lubrication system (100) for the lubrication of rotating or oscillating components with at least one oil suction pipe (3) arranged in an oil reservoir (1), an oil pump (4) connected to the oil suction pipe (3), and a heat source (7) connected to the oil pump (4) and downstream from this, further connecting lines (10) for feeding oil to lubrication points (11) that are structurally integrated into a metal structural environment (63) of a metal housing, after which oil is returned to the oil reservoir (1).

Abstract: A method is provided for heating a lubricating system. At low temperatures, lubricating oil has a high viscosity which requires more energy to be overcome than at higher temperatures. The method speeds up the heating behavior and thereby reduces the energy requirement of lubricating systems. The method can be used to heat lubricating systems for combustion engines or transmissions, preferably automatic transmissions, including at least one oil suction tube which is disposed in an oil sump and an oil bypass line bypassing the oil return lines. A bypass valve is disposed in the oil bypass line.
