摘要： PROBLEM TO BE SOLVED: To reduce a machining time and thus reduce machining cost and product cost by eliminating the need for conventional cutting work starting in the state in which no shaft hole (serration groove hole) and cut split exist in machining a joint element or a yoke and to improve the strength of the joint element or the yoke by avoiding the cutting of a metal flow as in the conventional cutting work.
SOLUTION: The joint member comprises the cut split 13 provided near the base end, a tubular joint cylinder portion 11 having the shaft hole for fitting a shaft, a pair of flange portions 16, 17 provided integrally with the joint cylinder portion 11 with the cut split 13 therebetween, a thread hole 18 formed in one of the flange portions 16, 17, and a through-hole 19 concentrically formed in the other flange portion, through which a bolt to be threaded to the thread hole 18 is inserted. The shaft hole and the cut split 13 are formed at the same time by forging.

摘要： PROBLEM TO BE SOLVED: To improve function of an EPS system by improving worm forming accuracy, especially tooth line accuracy, and reducing fluctuation of transmission torque between a worm and a worm wheel.
SOLUTION: A worm is manufactured by rolling a work W with two roll dies 1 and 2 arranged at an unequal angle pitch. Difference in balance of load due to difference in length of contact parts of the work W and the dies 1 and 2 is generated, but since the work W is formed, while rotating, for example the work W is rotated at 190°, and a part different from the condition wherein the work W is rotated at 0° is formed, load balance changes. In the formed worm, wave is hard to be generated in tooth line.

摘要： PROBLEM TO BE SOLVED: To provide a tubular worm formed with smooth tooth tip of a gear without generating bending by rolling a hollow raw material, which is formed hollow inside thereof, for formation.
SOLUTION: Fig.(a) is a cross section of the hollow raw material S, Fig.(b) is formed by narrowing the hollow raw material S, Fig.(c) is formed by rolling after narrowing in multiple stages, and Fig.(d) is formed by pressing an inside diameter spline to the rolled tubular worm. A mark 6 shows the inside diameter spline. Fig.(e) shows final process of grinding outside diameter and machining screw. A mark 7 shows a screw machining part, and a mark 8 shows an outside diameter grinding part. Since the hollow raw material formed hollow inside thereof is rolled for formation, breakdown of tooth tip and bending (tooth tip looks like being broken) are prevented, and tooth shape error and tooth line error are restricted small, and accurate formation is possible.

摘要： PROBLEM TO BE SOLVED: To provide a rolling-forming method with which the variation of a phase in a rolling die caused by a backlash of a speed reducer is removed by using a correcting movement with a simple program.
SOLUTION: In the rolling-forming method for forming a gear tooth on the outer surface of a blank with two round dies, when this forming method is applied by alternately changing the rotating direction of the two round dies into the normal rotation and the reverse rotation, mutual phase error is decided based on a second die phase at the time of matching the phase to the second die under the normal rotating operation in a first die put to the standard angle, and the second die phase at the time of matching the phase to the second die under the reverse rotating operation in the first die put to the standard angle. Then, in the formation of the gear tooth at the time of changing from the normal rotation to the reverse rotation or from the reverse rotation to the normal rotation, a main shaft rotating angle of the first die and a main shaft rotating angle of the second die are corrected according to the mutual phase error.
