Title:
GEAR MECHANISM AND A ROTARY ENCODER EQUIPPED WITH THIS GEAR MECHANISM
Document Type and Number:
WIPO Patent Application WO2003069281
Kind Code:
A3
Abstract:
The invention relates to a gear mechanism comprised of a rotating input element (100) and of a rotating output element (200), whereby at least one force transmission means (101, 102) is situated along a spiral line on a face of the input element (100). Force transmission means (201, 202) are situated along an encircling line on a face of the output element (200). The interaction of these force transmission means (101, 102; 201, 202) transmits a turning moment from the input element (100) to the output element (200), whereby this turning moment effects a rotating motion in the output element (200) so that the rotational speed is lower than the rotational speed of the input element (100). The invention also relates to a rotary encoder that is equipped with a gear mechanism of the aforementioned type.
