PURPOSE:To have quick oil supply to bearings at the time of starting, by forming a void under the shaft, allowing an oil suction pipe, whose bottom is immersed in an oil bath, at its top to open to the upper part of said void, and by forming an oil pan at the lower part of the shaft. CONSTITUTION:A stepped notch is provided in the lower part of a shaft 28, and a protruding space 33 is formed in linkage with a void 39 and a void 39. An oil suction pipe 32 is extended downward, the lower end being immersed open in an oil pan formed at the bottom part, while the upper end is inserted in the void 39 and further extended to a protruding space 33 being open therein. When the machine is stopped, such a state is brought about that the oil suction pipe 32 is filled with oil up to its top in the conical and cylindrical body 31, to assure that oil supply is resumed quickly when restarting is to be made. |
