[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clutch device having a novel structure.

[0002]

[Prior art]

 Conventionally, the clutch device 13 of this type is as follows. In what is composed of one rotating body 13A and the other rotating body 13B which is engaged with and disengaged from this one rotating body, the contact surfaces of both are formed with a meshing portion 13A1 and a meshing portion 13B1 in a flat state. There is. 13C is a coil spring.

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. It becomes large and the performance is poor.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, in the case of the present application, between the one shaft 2 rotatably supported and the other shaft 3 rotatably supported on the same shaft as the one shaft 2, the one rotor 4 is provided at the right end of the one shaft 2. The other rotor 7, which is engaged with and disengaged from the one rotor 4, is attached to the other shaft 3 so as to slide freely in the left-right direction. When the other shaft 3 is loaded, the other rotor 7 is separated from the one rotor 4. And the other rotor 7 is fixed in that state. In this case, the pulley 7C can be integrally formed on the right side surface of the truncated cone 7A in the clutch device 1.

【Example】

 Examples will be described with reference to the drawings. 1 is a clutch device of the present invention. Reference numeral 2 is a unidirectional shaft rotatably supported, and 2A is a bearing. Reference numeral 3 is the other shaft coaxially supported by the one shaft 2 and rotatably supported, and 3A is a bearing. Reference numeral 4 denotes a one-sided rotor fixed to the right end of the one-sided shaft 2. A laterally conical recess 4A is formed on the right side of the one-sided rotor, and the recessed part 4A has a radially wavy uneven surface. 4B is formed. The bottom of the recess 4A and the left end of the other shaft 3 are connected via a bearing 5.

Reference numeral 6 denotes a spline groove formed on the outer peripheral surface of the left portion of the other shaft 3, and a flange 6 A is provided at a right position of the spline groove 6. The other rotor 7 is attached to the flange 6A of the other shaft 3 slidably in the left-right direction. The other rotor 7 can be fitted into the conical recess 4A of the one rotor 4 from the right side. It is composed of a frustoconical body 7A configured and a corrugated concavo-convex surface 7B formed on the surface of the conical frustoconical body so as to be engaged with and disengaged from the corrugated concavo-convex surface 4B of the first rotor 4. .

Reference numeral 8 denotes an outer frame which is coaxially supported on the right side surface of the other rotor 7 via a spacer 8A. Numeral 9 is a stopper configured to bend a spring plate laterally in a U shape and to act inward. On the other hand, between the right side surface of the rotor 7 and the outer frame 8, the spline groove 6 is formed from above and below. It is mounted in a sandwiched state.

Reference numeral 10 denotes a receiving groove formed on the upper and lower surfaces of the spline groove 6 of the other shaft 3 in a direction orthogonal to the longitudinal direction of the spline groove. As a result of the load being applied to the other rotor 7 side, one rotor 4, the wavy uneven surface 7B of the other rotor 7 tries to separate from the wavy uneven surface 4B of the recess 4A in 4 and the other rotor 7 slides to the right and the outer frame 8 also moves. On the other hand, a stopper 9 acts between the right side surface of the rotor 7 and the outer frame 8 to enter the receiving groove. Reference numeral 11 denotes an outwardly acting coil spring arranged between the flange 6A and the outer frame 8.

Reference numeral 12 is a clutch device according to another embodiment. As for the structure, a known pulley 7C is integrally formed on the right side surface of the truncated cone 7A in the clutch device 1.

The present invention operates as follows. When the load is applied to the other rotor 7 side for some reason, the wavy uneven surface 7B of the other rotor 7 tries to separate from the wavy uneven surface 4B of the recess 4A of the one rotor 4. On the other hand, the rotor 7 slides to the right and the outer frame 8 also moves. In this case, the stopper 9 acts between the right side surface of the rotor 7 and the outer frame 8 to enter the receiving groove 10. Therefore, the other rotor 7 is held in a state of being disconnected from the one rotor 4, so that power is not transmitted from the one shaft 2 as the input shaft to the other shaft 3 as the output shaft.

[0012]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. On the one hand, the concave and convex portion 4A of the rotor 4 is formed with a wavy uneven surface 4B in a radial shape, and on the other hand, on the surface of the truncated cone 7A of the rotor 7, the wavy surface is formed so as to engage with and disengage from the uneven surface 4B. Since the uneven surface 7B is configured, the entire size can be reduced and the performance can be further improved.
