Abstract
A linear guide includes a guide carriage (1) arranged on a guide rail (2) so as to be longitudinally displaceable, and comprising a length measuring device (5) provided on the guide rail (2) for determining a position of the guide carriage (1), which length measuring device has two measuring heads (6) and two tracks (7, 8) arranged side-by-side on the guide rail (2), each of which tracks is assigned to one of the measuring heads (6). Each of said tracks (7, 8) has a plurality of dimensional measures (9, 14) arranged one behind the other along the track (7, 8), wherein in an overlapping region (x1, yn, z1), the dimensional measures (9, 14) of both tracks (7, 8) overlap each other.
Claims18
A linear guide, comprising:
- a guide carriage arranged to be longitudinally displaceable on a guide rail, and the guide carriage having a length measuring device configured for determining a position of the guide carriage on the guide rail, the length measuring device having two measuring heads and two tracks arranged side-by-side on the guide rail, each of the two tracks being assigned to one of the two measuring heads, the two tracks each having a plurality of dimensional measures arranged one behind the other along the respective track, the dimensional measures of the two tracks overlapping one another in an overlapping region.
A linear guide comprising:
- a guide rail;
- a guide carriage arranged to be longitudinally displaceable on the guide rail;
- and
- a length measuring device configured for determining a position of the guide carriage on the guide rail, the length measuring device including a first track including first dimensional measures arranged one behind another and a second track including second dimensional measures arranged one behind another, the first track and the second track being arranged side-by-side on the guide rail,
- the length measuring device further including a first measuring head on the guide carriage arranged and configured for scanning the first track and a second measuring head on the guide carriage arranged and configured for scanning the second track,
- each of the first dimensional measures overlapping at least one of the second dimensional measures in a plurality of overlapping regions.
A method of creating a linear guide comprising:
- providing a guide carriage and a guide rail;
- providing a length measuring device configured for determining a position of the guide carriage on the guide rail by:
- providing a first measuring head and a second measuring head on the guide carriage, and
- providing a first track and a second track side-by-side on the guide rail, the first rack including first dimensional measures and the second track including second dimensional measures, the first dimensional measures overlapping the second dimensional measures in an overlapping region;
- and
- arranging the guide carriage longitudinally displaceable on the guide rail such that the first measuring head is arranged and configured for scanning the first track and the second measuring head is arranged and configured for scanning the second track.
