Problems solved by technology

[0005] However, in such a fixed structure of the rotating member, when the ring as the rotating member is fitted on the spline shaft, the ring may be eccentric with respect to the spline shaft, and therefore, the addendum surfaces of the external teeth and the teeth of the internal teeth may be separated. The press-fit allowance of the bottom surface changes, and local stress concentration in the radial direction of the inner circumference of the ring may occur

Embodiment 2

[0064] Next, in the second embodiment shown in FIG. 6, the cylindrical rotating member 30 is press-fitted and fixed on the shaft member 40 with a circular cross section, as shown in the enlarged cross section in FIG. 7, for example. In the shaft hole 31 of the rotating member 30, a first shaft hole 31a with an inner diameter of d1 and a second shaft hole 31b with an inner diameter d2 smaller than the first shaft hole 31a are formed. An annular groove 32 with a relatively large inner diameter is formed between the two shaft holes 31b. The side of the annular groove 32 close to the second shaft hole 31b is a vertical surface 32a perpendicular to the axial direction. The inner end of the vertical surface 32a is connected to the second A right-angled corner portion 33 is formed at the starting end of the press-fitting direction of the shaft hole 31b.

[0065] The rotation member 30 is formed in such a structure that the rotation member 30 is gradually pressed into the shaft member...

Abstract

A rotating member fixing structure includes a shaft member and a rotating member. The rotating member has an axial bore section press-fitted to the shaft member. One of the shaft member and the axial bore section of the rotating member includes a margin adjusting part dimensioned to reduce a press-fitting margin between the shaft member and the axial bore section of the rotating member from an initial press-fitting margin to an effective press-fitting margin that is less than or equal to a prescribed value when the rotating member is press-fitted to the shaft member.

Description

technical field [0001] The present invention relates to a fixing configuration of a rotating member. Background technique [0002] Conventionally, as a fixing structure for such a rotating member, a structure in which internal teeth formed on the inner periphery of a ring as a rotating member and external teeth formed on the outer periphery of a spline shaft are fixed by press-fitting them has been proposed. [0003] In this fixing structure of the rotating member, the first press-fit portion and the second press-fit portion are dispersedly formed in the circumferential direction to alleviate local stress concentration in the circumferential direction of the inner circumference of the ring, thereby improving the strength and durability of the internal teeth. The first press-fit part is used to press-fit the top surface of the external tooth and the tooth bottom surface of the internal tooth, and the second press-fit part is used to press-fit the tooth surface of the external...
