| description | PROBLEM TO BE SOLVED: To provide a joining structure of a rotary element of a rotary structure with its drive shaft and a joining method associated therewith capable of establishing large coupling strength by using both screw coupling and pressure fit coupling, eliminating the risk of the loosening of coupling between the rotary element and the drive shaft even when torque in the opposite direction relative to the normal rotating direction is applied to the drive shaft, for example, when rotation is stopped, eliminating the risk of the dislocation or inclination of the axis, and establishing coupling of high reliability. SOLUTION: A rotor 1 of a vane pump is composed of the rotary element 2 made of aluminum or an aluminum alloy and the drive shaft 3 made of steel. The rotary element 2 has a preparatory hole 6 and a fitting hole 7 while the drive shaft 3 has a shaft 8, a tapping screw 9 and a pressure fitting part 10 at its joining side end, and when the tapping screw 8 is driven into the hole 6, a screw coupling part A is formed, and when the pressure fitting part 10 is fitted by pressure in the fitting hole 7, a pressure fit coupling part B is formed. The shaft 8 and a pressure fit coupling part A support two ends of the rotary element 2. COPYRIGHT: (C)2004,JPO |
