Definitions
- the present invention relates to a power transmission device for transmitting power from a drive source of a vehicle to, for example, a compressor of a vehicle air conditioner.
- a compressor of a vehicle air conditioner that is generally known includes a compressor main body formed in a hollow shape, a compression mechanism for compressing fluid sucked into the compressor main body, and a compression mechanism. And a coupled drive shaft.
- this compressor when the drive shaft is rotated by the power of the engine, the compression mechanism is driven. This compressor sucks and discharges refrigerant by driving a compression mechanism.
- the power transmission device provided in the compressor includes a first rotating body that can be rotated by power from an engine, a second rotating body that is disposed radially inward of the first rotating body, and a second rotating body.
- a rotating body is connected to the rotating body via a blocking mechanism and includes a third rotating body that can rotate together with the drive shaft.
- the first rotating body has a plurality of protrusions spaced from each other in the circumferential direction.
- the second rotator has a plurality of protrusions facing the protrusions of the first rotator in the circumferential direction.
- a buffer member is provided between each protrusion of the first rotator and each protrusion of the second rotator, and each buffer member has a block shape. Each buffer member transmits the first rotating body force to the second rotating body.
- Patent Document 1 Japanese Patent Laid-Open No. 2003-269489
- each buffer member when the first rotating body is rotated by the power of the engine force, each buffer member is elastically deformed in the circumferential direction of the first rotating body. That is, each buffer member is elastically deformed in the compression direction. Thereby, each buffer member absorbs the rotational fluctuation transmitted to the engine force. Each buffer member also transmits the first rotating body force to the second rotating body. For this reason, each buffer member is repeatedly elastically deformed in the compression direction, thereby compressing each buffer member. Directional permanent distortion occurs. In addition, the buffer effect is reduced by permanent distortion. Further, a gap is generated between each protrusion of each rotating body and each buffer member due to permanent distortion. The gap causes vibration between the first rotating body and the second rotating body.
- the object of the present invention is to maintain the buffering effect of the buffer member over a long period of time.
- the present invention also provides a power transmission device that can simplify the assembly process of the buffer member.
- a power transmission device includes a first rotating body that can be rotated by external power, and a second rotating body that is disposed radially inward of the first rotating body.
- the first rotating body is disposed between the first rotating body and the second rotating body, and the inner peripheral surface is fixed to the outer peripheral surface of the second rotating body, so that the first rotating body force is transmitted to the second rotating body.
- the annular cushioning member, the third rotating body disposed radially inward on the second rotating body side, and the second rotating body force between the second rotating body and the third rotating body.
- Rotational force can be transmitted, and when torque of a predetermined magnitude or more is generated between the second rotating body and the third rotating body, the rotational force transmitted from the second rotating body to the third rotating body is A blocking mechanism for blocking, a plurality of convex portions provided on the outer circumferential surface of the buffer member at intervals in the circumferential direction, and an inner circumferential surface of the first rotating body. And a plurality of concave portions fitted to the respective convex portions of the buffer member.
- the buffer member is sheared between the outer peripheral surface and the inner peripheral surface. Rotational force is transmitted while elastically deforming. Therefore, it does not elastically deform in the direction of compression repeatedly as in the case of conventional buffer members. That is, since the permanent deformation in the compression direction does not occur in the buffer member, there is no decrease in the cushioning effect. For this reason, the buffer effect by the buffer member can be maintained for a long time. In addition, since the assembling work of the buffer member is easy, the manufacturing cost can be reduced.
