Here, the teeth 2
Shows an example in which the gear 3 engraved with is fixed to the rotating shaft 4. The friction joint 1 is formed with a cylindrical cavity 6 coaxial with the center hole 5 of the gear 3. By pressurizing oil, grease, or the like as a pressure medium sealed in the cavity 6, the gear 3 is pressed. In addition, the contact pressure of the contact surface of the friction joint 1 with respect to the rotating shaft 4 is increased, whereby the frictional force is increased, and the relative rotation between the gear 3 and the rotating shaft 4 is restricted.

不都合を防止するため、回転軸に対する高い取付精度が
要求されることがある。By the way, in fixing the mechanical element for transmitting the rotary motion to the rotary shaft,
Of course, it is firmly connected and fixed to the rotating shaft so that the predetermined motion transmission is reliably performed between the rotating shaft and
In order to suppress the occurrence of vibrations and abnormal noises and to prevent inconveniences such as breakage during high-speed motion, high mounting accuracy with respect to the rotating shaft may be required.

はない。In this case, it is necessary to manufacture each of the mechanical element and the rotating shaft with high accuracy. However, while the accuracy of the rotating shaft can be obtained relatively easily, the manufacturing accuracy of the mechanical element, particularly, the engagement of the outer periphery is required. It is not easy to increase the accuracy of the coaxiality between the means and the center hole. For example, in the case where the shaft is fixed through the center hole in the forming process, the coaxiality accuracy is reduced due to the clearance generated between the fixed shaft and the center hole, and in order to avoid this, accurate positioning is required. Manufacturing costs are significantly increased. In addition, in the fixing method in which the friction joint 1 is interposed, it is not always easy to obtain a high mounting accuracy because the manufacturing accuracy of the friction joint 1 greatly affects the mounting accuracy.

要因となる。On the other hand, if the required accuracy cannot be achieved in the molding process, it is possible to perform a retouching operation after the forming process. However, this retouching operation is performed manually using a hammer or the like. In this case, an expensive dedicated device for retouching is used, and in any case, the cost is increased.

Molding with high coaxiality accuracy is possible. In addition, positioning is automatically performed by the operation of fixing the pressure medium to the fixed shaft, and the operation of pressing the pressure medium itself can be performed relatively easily. Thus, it is possible to suppress the increase in the number of steps in the molding process and to improve the efficiency.
