ORTHOGONAL TYPE ROLLING TRANSMISSION GEAR

Japanese Patent JP3457700

B2

PURPOSE: To provide an orthogonal type rolling transmission gear desirable in durability and capable of obtaining high transmission torque with almost no slip.
CONSTITUTION: An orthogonal type rolling transmission gear is provided with an input shaft 31 supported at a housing 35 and provided integrally with a small diameter taper roller 36; an output shaft 38 orthogonal to the input shaft 31 and supported in the state of being slightly movable in the axial direction; a torque cam plate 49 fixed to the output shaft 38; a large diameter taper roller 41 supported on the output shaft 38 and provided with a large diameter taper roller cam part 41a of the same shape as the torque cam plate 49, a torque cam roller 50 held between the torque cam plate 49 and the large diameter taper roller 41 so as to apply thrust to the large diameter taper roller 41 while transmitting torque; and an idle taper roller 42 supported on the output shaft 38, with the back face side constrained by a thrust bearing 45. A pair of large diameter taper rollers 41, 42 are disposed with the small diameter taper roller 36 held in between, and pressure contact force between the taper rollers is automatically increased/decreased in proportion to the output torque.
