Abstract

PURPOSE: To improve the lubrication characteristic and to simplify the assembly, by pressing a spiral member for scooping the lubrication oil against the inner wall of a hole in a rotary shaft by means of a cylindrical member made of a stainless steel plate, then using the space formed by the rotary shaft and the cylindrical member as an oil flow path.
CONSTITUTION: The outer diameter of a spiral member 11 in a rotary shaft 7 is slightly shorter than the inner diameter of a hole 7b made at the tip of the rotary shaft 7, where the spiral member 11 is fitted in the hole 7b while a cylindrical steel plate spring 12 is fitted at the inner diameter side of the spiral member 11. As the rotary shaft 7 rotates, the spiral member 11 will scoop the lubrication oil at the tip thus to feed to an oil hole 7c. With such structure the space formed by the rotary shaft 7 and the cylindrical member 12 will provide an oil flow path, thus to provide a good lubrication characteristic. Since the spiral member 11 is simply jointed with the rotary shaft 7, general molding tolerance can be applied on each part when fitting resulting in quite simple assembling structure.
