Abstract
A rotary encoder (1) comprising a housing (2), a shaft (3), a code disk (4) which is attached to the shaft (3), and a reading head (5) which is designed to detect the rotation of the code disk (4) are disclosed herein. The code disk (4) is affixed in the axial position thereof on an axial side by way of an abutment (6), and a resilient element (7, 17, 19) is arranged on the other axial side providing a clamping force for pressing the code disk (4) against the abutment (6). A method for assembling a rotary encoder is also disclosed herein.

A rotary encoder (1), comprising:
- a housing (2);
- a shaft (3);
- a code disk (4) which is attached to said shaft (3);
- and
- a reading head (5) which is configured to detect the rotation of said code disk (4);
- wherein said code disk (4) is affixed in an axial position on one axial side by an abutment (6) on said shaft (3);
- and
- a resilient element (7, 17, 19) is arranged on another axial side of said code disk and provides a clamping force with which said code disk (4) is pressed against said abutment (6) wherein said resilient element (7) is an annular or cylindrical elastomer element.
A rotary encoder, comprising:
- a housing (2);
- a shaft (3);
- a code disk (4) which is attached to said shaft (3);
- and
- a reading head (5) which is configured to detect the rotation of said code disk (4);
- wherein said code disk (4) is affixed in an axial position on one axial side by an abutment (6) on said shaft (3);
- and
- a resilient element (7, 17, 19) is arranged on another axial side of said code disk and provides a clamping force with which said code disk (4) is pressed against said abutment (6), wherein said resilient element (17, 19) is a disk spring or finger spring having a central opening therein, wherein said shaft (3) is arranged in said central opening.
A method for assembling a rotary encoder (1) comprising the steps of:
- providing a housing lower part (12) with a lower bearing (11);
- arranging a code disk (4), a resilient element (7, 17, 19) comprising one of an annular elastomer element, a cylindrical elastomer element, a disk spring, or a finger spring, and an upper bearing (9) on a shaft (3);
- introducing said shaft (3) into a housing upper part (13);
- arranging and attaching said housing upper part (13) to said housing lower part (12) so that said shaft (3) is mounted by said upper bearing (9) and said lower bearing (11), and a clamping force is applied by said upper bearing (9) via said resilient element (7, 17, 19) so that said code disk (4) is pressed against an abutment (6) on said shaft (3).
