Weidmann, Josef (Altenmarkt, DE); Speckbacher, Peter (Kirchweidach, DE) |
| Claim: |
1. An arrangement for a scale, the arrangement comprising: a scale comprising a measurement graduation that defines a measurement range; a support arranged opposite to said measurement graduation; and spheres arranged two-dimensionally distributed on said support, wherein said spheres are immovably fixed on said support and to said scale. |
| Claim: |
2. The arrangement in accordance with claim 1, further comprising a holding structure that immovably retains said spheres on said support and to said scale, wherein said holding structure cause a material-to-material connection between said spheres and both said support and said scale. |
| Claim: |
3. The arrangement in accordance with claim 2, wherein said holding structure comprises: a first layer arranged on said support; and a second layer arranged on said scale, wherein said spheres are embedded in said first layer and said second layer. |
| Claim: |
4. The arrangement in accordance with claim 2, wherein said holding structure comprises a layer in which said spheres are embedded. |
| Claim: |
5. The arrangement in accordance with claim 1, wherein said spheres are arranged at a mutual distance as measured from their centers, wherein said mutual distance is less than a thickness of said scale. |
| Claim: |
6. The arrangement in accordance with claim 1, wherein said spheres are arranged and fastened in such a way that said spheres define free spaces between each other, which constitute outward-leading channels. |
| Claim: |
7. The arrangement in accordance with claim 1, wherein said support and said scale have identical thermal coefficients of expansion. |
| Claim: |
8. The arrangement in accordance with claim 7, wherein said thermal coefficients of expansion of said support and said scale have a value that is less than 1.5×10−6K−1. |
| Claim: |
9. The arrangement in accordance with claim 7, wherein said thermal coefficients of expansion of said support and said scale have a value that is less than 0.1×10−6K−1. |
| Claim: |
10. A position measurement system, comprising: an arrangement for a scale, the arrangement comprising: a scale comprising a measurement graduation that defines a measurement range; a support arranged opposite to said measurement graduation; and spheres arranged two-dimensionally distributed on said support, wherein said spheres are immovably fixed on said support and to said scale; and a scanning unit that scans said measurement graduation and generates position-dependent signals, wherein said scanning unit and arrangement move relative to one another in a scanning direction. |
| Claim: |
11. The position measuring system of claim 10, wherein said measuring graduation is an incremental graduation. |
| Claim: |
12. The position measuring system of claim 10, wherein said scanning unit photo-electrically scans said measuring graduation. |
| Claim: |
13. The position measuring system of claim 10, further comprising a holding structure that immovably retains said spheres on said support and to said scale, wherein said holding structure cause a material-to-material connection between said spheres and both said support and said scale. |
| Claim: |
14. The position measuring system of claim 13, wherein said holding structure comprises: a first layer arranged on said support; and a second layer arranged on said scale, wherein said spheres are embedded in said first layer and said second layer. |
| Claim: |
15. The position measuring system of 13, wherein said holding structure comprises a layer in which said spheres are embedded. |
| Claim: |
16. The position measuring system of claim 10, wherein said spheres are arranged at a mutual distance as measured from their centers, wherein said mutual distance is less than a thickness of said scale. |
| Claim: |
17. The position measuring system of claim 10, wherein said spheres are arranged and fastened in such a way that said spheres define free spaces between each other, which constitute outward-leading channels. |
| Claim: |
18. The position measuring system of claim 10, wherein said support and said scale have identical thermal coefficients of expansion. |
