られている。2. Description of the Related Art Generally, a vehicle power transmission device and the like are provided with a plurality of torque transmitting members, and torque is transmitted between these torque transmitting members.
Here, a shaft member fitting structure is used as a configuration for connecting a plurality of torque transmitting members in a state where relatively large torque can be transmitted without using a special connecting member.

におけるトルクの伝達が可能な状態になる。[0003] The fitting structure of the shaft member includes a first shaft member having a plurality of internal teeth formed on an inner periphery of a hole, and a second shaft member having a plurality of external teeth formed on an outer periphery. . Then, by inserting the second shaft member into the hole, the plurality of inner teeth and the plurality of outer teeth mesh with each other, so that torque can be transmitted between the second shaft member and the first shaft member. become.

が設定されている。[0004] As described above, in the fitting structure of the shaft members, the first shaft member and the second shaft member are connected to each other through the process of relatively moving in the axial direction of the hole. Therefore, in order to reduce the insertion resistance when inserting the second shaft member into the hole, a predetermined gap is formed in the circumferential direction between the plurality of internal teeth and the plurality of external teeth, The dimensions of the plurality of internal teeth and the plurality of external teeth are set.

あった。However, if the first member and the second member are connected in a state where a circumferential gap is formed between a plurality of internal teeth and a plurality of external teeth, a change in torque causes a change in the gap. The second shaft member and the first shaft member relatively move in the circumferential direction within the range. As a result, there is a possibility that the first shaft member or the second shaft member vibrates or noise is generated at a meshing portion between the internal teeth and the external teeth.

が圧入固定されている。Here, in a state where the first shaft member and the second shaft member are connected, a shaft member capable of preventing relative movement in the circumferential direction between the first shaft member and the second shaft member. An example of a fitting structure and a fitting method is disclosed in Japanese Patent Application Laid-Open No. 58-2111018.
No., published in Japanese Patent Application Publication No. In the fitting structure of the shaft member described in this publication, a part of the valley of the teeth (internal teeth) of the female spline (first shaft member) is plastically deformed, and the length of the valley in the circumferential direction is increased. Is formed so as to be partially narrow. Then, a male spline (second shaft member) is added to the female spline.
Is press-fitted and fixed.

雌形スプラインに圧入して製造されている。In other words, in the fitting structure of the shaft member described in this publication, a part of the teeth of the female spline is plastically deformed so that the circumferential length of the valley is partially reduced. Thereafter, heat treatment such as quenching is performed, and the male spline is press-fitted into the female spline.

を防止することができるとされている。According to the fitting structure and the fitting method of the shaft member described in the above-mentioned publication, the interval between the valleys of the teeth of the female spline is narrowed, so that the pair of male and female splines extend in the circumferential direction. It is meshed and pressed in without any gap. Therefore, even when the torque transmitted between the pair of male and female splines changes, relative movement of the pair of male and female splines in the circumferential direction can be prevented.

Mutually press fit. For this reason, local stress concentration occurs in the inner circumference of the female spline in the circumferential direction, and when the press-fitting load at the time of press-fitting is high, the outer shape of the female spline may be deformed or the strength may be reduced.

る。Also, in this embodiment, the first press-fitting portion B1 and the second press-fitting portion C1 and the region where neither the first press-fitting portion B1 nor the second press-fitting portion C1 are formed have separate outer spline teeth. 8 are formed. In other words, at the position facing the single tooth space 6, one of the first press-fit portion B1 and the second press-fit portion C1 is formed, or the first press-fit portion B1 and the second press-fit portion C1 are formed. Neither is formed. That is, the first press-fitting portion B1 and the second press-fitting portion C1 are not formed in the single tooth space 6 but are dispersed in the circumferential direction of the ring 2.

久性が向上する。For this reason, when the spline shaft 3 is fitted inside the hole 4, the inner periphery of the hole 4 is plastically deformed. However, local stress concentration in the circumferential direction of the hole 4 is reduced, and the internal teeth 5
Cracks, defects, cracks, etc. in the fillet at the base of the tooth are suppressed.
Therefore, the strength and durability of the internal teeth 5 are improved. Also,
Even when the thickness of the ring 2 in the radial direction is relatively thin, deformation of the outer peripheral shape of the ring 2, specifically, the outer peripheral teeth 7 is suppressed, and the accuracy of the shape is maintained. Accordingly, the outer peripheral teeth 7 of the ring 2 and a rotating member (not shown) that meshes with the outer peripheral teeth 7.
Gear noise is suppressed, and the strength and durability of the outer peripheral teeth 7 are improved.

The effect of the fitting load on the outer peripheral shape of the ring 2 when the outer peripheral teeth 7 are fitted will be described by taking the pressure angle θ1 of the outer peripheral teeth 7 shown in FIG. 4 as an example. The pressure angle θ1 is determined by the tooth surface 1 of the outer peripheral tooth 7.

FIG. 6 is a diagram comparing an amount of change in an error. Here, in the comparative example, the first press-fitting portion plastically deformed by bringing the tooth tip surface of the external tooth and the tooth bottom surface of the internal tooth into contact with each other at a position facing a single tooth space of the internal tooth, A second press-fit portion is formed by bringing the tooth surface of the tooth into contact with the tooth surface of the internal tooth and plastically deforming each other.

To n) are shown. According to FIG. 7, it can be seen that the change rate of the change amount of the pressure angle θ1 in the example is smaller than the change rate of the change amount of the pressure angle in the comparative example. The reason why such a difference occurs is that, in the comparative example, the first press-fitted portion and the second press-fitted portion are formed at a position facing a single tooth space of the internal teeth, and a local portion is formed on the inner peripheral surface of the ring. This is because stress concentration occurs, and as a result, the external teeth are easily deformed.

If this configuration is adopted, when the ring 2 and the spline shaft 3 move relative to each other in the circumferential direction during torque transmission and the tooth surfaces 11 and 12 come into contact with each other, the tooth surfaces 11 and 12 Surface contact reduces the contact pressure per unit area, and suppresses deformation, loss, and cracking of the tooth surface 11 or 12. Note that it is also possible to use a square spline shaft in which the teeth of the spline shaft 3 are substantially rectangular. Furthermore, a serration shaft can be used as the inner member of the present invention.
