摘要： The present invention provides a transmission unit that can realize a high speed-shifting ratio, can realize reduced size, low cost and low noise, and is also capable of limiting slip loss. Outer peripheral surfaces of a small diameter rolling element and a supplementary rolling element are brought into contact with an outer peripheral surface of a large diameter rolling element. The supplementary rolling element is arranged at an almost opposite side to the small diameter rolling element, thus enclosing the large diameter rolling element between the small diameter rolling element and the supplementary rolling element. An inner peripheral surface of the pressure adjustment ring is brought into contact with the outer peripheral surface of the small diameter rolling element and the outer peripheral surface of the supplementary rolling element, and is supported by them. If the small diameter rolling element rotates, the pressure adjustment ring rotates by means of the large diameter rolling element and the supplementary rolling element. If load is applied to rotation of the large diameter rolling element, the pressure adjustment ring is made eccentric. In this way, the small diameter rolling element receives pressing force toward an inner side in the radial direction of the large diameter rolling element, from the pressure adjustment ring.

摘要： A stepless speed change traction gear includes a plurality of conical rollers, each having a conical surface frictionally engaging with an internal surface of a speed changing ring, a flat surface perpendicular to the axis of the conical surface frictionally engaging a non-rotating track ring, and an annular concave surface coaxial with the conical surface and frictionally engaging a bearing ring. The speed changing ring is longitudinally adjustable between limits so that a speed ratio range from 0 to nearly 1.0 is developed. This traction gear is not provided any additional gearing or speed increasing device to widen the speed range. A clutch, brake, and operator can permit a direct drive condition between the input and output shafts.

摘要： A stepless speed change gear has an axially movable speed changing ring that is frictionally engaged with a plurality of conical rollers. The stepless gear has improved durability and reduced weight due to a flat annular power transmitting surface and an annular power transmitting surface of arcuate cross-sectional contour on the bottom portion of each conical roller. A force caused by a contact pressure generating device is applied to the conical rollers at the annular power transmitting surface of arcuate cross-sectional contour, so as to advance the conical rollers into a space between the speed changing ring and another frictionally engaging member as a wedge so that required contact pressures are applied on the frictionally engaging points.

摘要： A type of a stepless speed change gear has a plurality of conical rollers each of which has a conical surface frictionally and internally engaging a ring-member moved axially by a speed changing device, a first annular surface frictionally engaging a disc of small diameter on an input shaft and a second annular surface frictionally engaging with a disc or large diameter arranged coaxially with the input shaft, and a contact pressure generating device of cam-type for generating contact pressures at three frictionally engaging points on each of the conical rollers. An assembly in which thrusting due to the friction-drive does not act onto the casing is provided. In the assembly, the disc of small diameter, the disc of large diameter and the contact pressure generating device are supported by a single shaft prohibiting running-out of them in axial direction. In addition, the conical rollers are bundled by the ring-member so that they will not drop out of the assembly.
