Abstract

PURPOSE: To provide a light and highly strong hollow shaft, by machining the inner surface of the hollow shaft in proportion to the change of diameter at the outer surface and thereby providing definite diameter change in a wide range along the length of the hollow shaft.
CONSTITUTION: On both sides of hollow axle 1, there are respectively formed a bearing fixing portion 2A, and oil throwing portion 2B and an axle fixing portion 2C on its outer surface 2. On one side of the shaft 1, a gear fixing portion 2E is formed at a portion nearer to intermediate portion 2D than to the axle fixing portion 2C. On said one side of the axle 1, there are further formed another bearomg fixing portion 2F and a current collecting ring fixing portion 2G, thereby providing a definite axial diameter change in a wide range along the outer surface 2 of the axle 1. Inner surface 3 of hollow axle 1 is machined to have diameters substantially proportional to the axial diameter change of hollow axle 1 and rollered to produce residual compressive stress on the same. Inner surface machining apparatus 4 is turned while supporting axle 1 by means of chuck 6 and roller support 7 and machines the inner surface of axle 1 by the tool iattached at the top of boring bar 8.
