Title:
FRICTION GEARING
Document Type and Number:
Japanese Patent JP2010209953
Kind Code:
A
Abstract:

To provide a friction gearing improved in the durability of an output transmission system by reducing a load of a universal coupling between an output roller and an output shaft.

The amount of the extension of bearing supports 23, 25 is increased by a prop-up force in the mutually separating direction of rollers in the case of bringing the output roller 32 close to an input roller 31 from the bottom dead center (a) to the top dead center (b) to increase a torque capacity. The increase of the offset amount is thereby reduced to improve the durability of the output transmission system. Since an axis O1 is radially fixed but an axis O2 and its turning center O3 are not radially restricted, the extension of the bearing supports 23, 25 converges at the output roller side, and the output roller turning center O3 can be displaced largely as shown by γ2. Consequently, the variation 2 of the axis O2 can be reduced to improve the durability of the output transmission system.
