Embodiment Construction
[0016] Such as figure 1 , 2 , 3, the lubricating structure of a rotary spline of the present invention includes a spline shaft 1, a spline sleeve 2 and a pressure plate 3, and the spline shaft 1 and the spline sleeve 2 rely on the spline pair 4 to cooperate, so There is an oil discharge hole 3-1 on the pressure plate 3, the pressure plate 3 is fixed on the free end 1-1 of the spline shaft 1, and is offset against one end of the spline sleeve 2, and the free end of the spline shaft 1 is A shoulder 1-2 is provided at the opposite spline end of 1-1, and the shoulder 1-2 is offset against the other end of the spline sleeve 2, and several Circumferentially distributed radial oil collection grooves 2-1, the spline end of the spline shaft 1 opposite to the free end 1-1 also has a circumferential inclined bottom oil chamber 1-3, and the circumferential inclined bottom oil chamber One end of 1-3 communicates with the radial oil collection groove 2-1 distributed in the circumferential...
