Arrangement for transmitting a torque between a shaft and a hub |
摘要 |
An arrangement transmits a torque between a shaft and a hub. The hub has at least approximately the interior geometry of an equilateral n-sided polygon, the side surfaces of which at least approximately bear against a clutch portion, which is of circular overall cross section, of the shaft, and wherein the shaft has at least one driver portion which is rotationally conjoint with respect to the clutch portion and which extends in the direction of a corner of the n-sided polygon. |

1. A torque transmission arrangement comprising:
a hub defining at least approximately an interior geometry of an equilateral n-sided polygon having side surfaces; a shaft including (i) a coupling portion defining a circular overall cross section, (ii) at least one driver portion rotationally fixed relative to the coupling portion and extending in a direction of one corner of the n-sided polygon, and (iii) a driver element accommodated in an aperture in the coupling portion of the shaft, wherein the side surfaces of the n-sided polygon at least approximately bear against the coupling portion of the shaft; wherein the arrangement is configured to transmit a torque between the shaft and the hub; and wherein the at least one driver portion has a shape of a spherical cap and is defined on the driver element. |
