Abstract

PURPOSE:To relieve stress concentration by forming splines to have irregular lengths so that the ends thereof will not be arranged in a line. CONSTITUTION:A plurality of splines 3 are formed on the outer peripheral surface at one end of the shaft 1 in the axial direction. The ends 3A of the splines 3 are arranged irregularly with respect to the adjacent ones in the axial direction. By this irregular arrangement of the spline ends, when rotation torque is exerted on the splines 3, the stress concentration point is also irregular with respect to each spline 3 in the axial direction, thereby the excess concentration of stress is mitigated.

。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spline shaft suitable for use in cases where a large rotational torque is applied to the spline shaft, such as in the propeller shaft of an automobile.

れてなる。As shown in Fig. 1, a conventional spline shaft is made by forming splines 2 on the outer peripheral surface of the shaft 1 in parallel to each other in the axial direction and with their two ends aligned by rolling or cutting. It will be done.

Stress concentration occurs on these terminals and ml! Since the strength of this part was reduced, the size of the spline was 11, and the other parts were disadvantageous in weight.

本発明の目的は、前記問題点を解消できるスプライン軸

るようにしたことにある。An object of the present invention is to provide a spline shaft that can solve the above-mentioned problems, and its feature is that the spline O ends are uneven to alleviate the occurrence of stress concentration O.

以下ｇｉｇｉに即して本ｌｉ＠の実施例を説明する。An example of this li@ will be described below based on gigi.

方向にずれて不揃いとなっている゛。Fig. 11112 shows an embodiment of the present invention, in which a plurality of splines 3' are formed in the axial direction on the outer circumferential surface of one end of the shaft 1 (corresponding to the second m). The terminals 3 of each spline 30 are misaligned with each other in the axial direction with respect to the adjacent splines.

る。In this way, since the three terminals of the spline 3 are not aligned, even if rotational torque is applied to the spline 3 group, the stress concentration point will shift in the direction of rotation toward the center of each spline 3, so the Ill will be relaxed. That will happen. Therefore, the decrease in *[ due to stress concentration on the shaft 1 is avoided, the overall size of the tin 2-in can be avoided, and the weight can be reduced.

。Note that it is preferable that the mutual deviation between the terminals of adjacent splines be as large as possible. Also, there is no point where the terminals match over the entire spline group, that is, the neighbor 1
It is desirable that the spline group as a whole, not just the eaters, be uneven. Furthermore, if the irregularity is irregular, the effect of diffusing the stress concentration is further improved.

その結果プロペラシャフトの軽量化が計られる。As a result, the weight of the propeller shaft can be reduced.
