SPLINE COMPONENT UNIT AND ITS FITTING METHOD

PROBLEM TO BE SOLVED: To provide spline components and their fitting method which enable the simultaneous restriction of frictional resistance while axially and relatively sliding a first member and a second member axially and slidably engaged with inner teeth and outer teeth in a simple structure, and a gap when rotating around a shaft. SOLUTION: Outer splines 10 are formed on a male component 1, and inner splines 20 are formed on a female component 2. A designated tooth T' among at least one side of teeth T between the outer splines 10 of the male component 1 and the inner splines 20 of the female component 2 is formed into a deformed tooth being different from a shape of a tooth groove Ts so as to be point contact with a tooth face of other corresponding tooth groove Ts at a cross section, and one teeth T and T' and other tooth groove Ts are fit each other by relatively sliding to an axial direction. The male component 1 and the female component 2 are expanded and contracted by sliding the outer spline 10 and the inner splines 20 to an axial direction. COPYRIGHT: (C)2005,JPO&NCIPI
