Traction oil is used to promote fluid friction on the transfer surface, and power is transmitted using the rolling friction generated by the hardening of the fluid friction-enhancing film on the transfer surface, which improves practical performance, especially rolling friction coefficient, or traction. The coefficient was insufficient, and as a device for transmitting constant power, it was larger than a gear power transmission device.

の転走面即ち内周面に押圧されている。 In the drawing, 1 and 2 are mounted on a driving shaft 3 and a driven shaft 4 which are arranged in parallel, with the large diameter end and the small diameter end facing in opposite directions, and with their conical surfaces facing each other. The cone 5 is a ring frictionally engaged between the cones 1 and 2, and by moving this ring in the axial direction, the contact rotation radius of the cones 1 and 2 is changed, and the drive shaft 3
and the speed ratio of the driven shaft 4 is changed. Incidentally, the surfaces of the cones 1, 2 and the ring 5 are treated with chrome plating or the like to prevent oxidation. 6 and 7 are metal powders of soft metals such as lead and zinc and their alloys,
A feeder made of a powder of a synthetic resin that can be molded at a temperature lower than the soft metal, such as a thermoplastic resin such as nylon resin, or a thermosetting resin such as a phenol resin, and is held by the feeder holder 8. Ring 5 via springs 9 and 10
It is pressed against the rolling surface, that is, the inner peripheral surface.

A coil spring 12 is interposed between the feeders 6 and 7.
7 is pressed against the inner circumference rolling surface of the ring 5 with a predetermined pressing force.

置の小型化が可能である。 In the above configuration, when the cone 1 rotates, the ring 5 rolls and rotates due to the frictional force, and the cone 2 further rotates due to the rolling frictional force. As mentioned above, when the cones 1, 2 and the ring 5 rotate, the feeders 6, 7 are pressed against the rolling surface of the ring 5, so that the synthetic resin component gradually wears out, and the soft metal always remains constant. The powder falls off from the feeder and transfers to the inner raceway surface of the ring.
Then, power is transmitted through the soft metal powder transferred at the contact portion between the cones 1 and 2 and the ring 5. As a result, the traction coefficient can be increased without causing wear at the contact portions between the cones 1 and 2 and the ring 5, the transmission capacity can be increased, and the device can be made smaller.

In the shock drive device, a feeder that presses the inner rolling surface of the ring at a fixed position is configured by heating and molding a mixture of soft metal powder and synthetic resin powder whose melting point is lower than that of the soft metal powder. The rotation gradually wears out the synthetic resin component of the feeder, causes the soft metal powder to fall off the feeder and transfer to the inner raceway surface of the ring, and power is transferred between both shafts and the ring via the soft metal powder. Since the transmission of The practical effects are enormous.
