Abstract

PURPOSE: To increase the power to supply oil without lowering the bending strength of shaft by a system in which a spiral wire fixed in the longitudinal hole of a shaft is turned by an oil supply pump inside an enclosed type compressor and then lubricating oil is pushed up by its feeding action to supply oil.
CONSTITUTION: The coil 22 formed by winding a wire spirally into an almost cylindrical shape is pressed into the longitudinal hole 14 of the shaft 4 or fixed with a slight clearance in it. When the shaft 4 rotates, the lubricating oil 12 pushed up by the curved portion 13' of the piece 13 collides against the upper surface 22' of the coil 22, whereupon the lubricating oil 12 is pushed up because the coil 22 is wound in such a direction that the components of collison force are produced upwardly. And, oil is supplied to the clearances 19W21 through the horizontal holes 16W18. Because the upward components of collision force can be increased by making the sprial pitches of the coil 22 smaller, the inside diameter of the longitudinal hole 14 is enlarged and the amount of oil to be supplied is increased without lowering the bending strength of the shaft 4.
