Abstract
A hydrostatic profile of a rail guide with a guide carriage. Viewed in cross-section through the rail guide, there is an imaginary first straight line parallel to the mid-surface, an imaginary second straight line parallel to an upper bearing surfaces and a third imaginary straight line parallel to a lower bearing surface. An angle alpha is formed between the first and the second straight lines, and an angle gamma is formed between the first and the third straight lines. The angle alpha has values of 10° to 45 ° inclusive and the angle gamma has values of 20° to 55° inclusive.

A hydrostatic profiled-rail guide, comprising:
- a guide carriage which is hydrostatically mountable on a guide rail,
- the guide rail having a central surface extending along a longitudinal axis of the profiled-rail guide, two upper bearing surfaces which are arranged at both longitudinal sides of the central surface and which are arranged inclined with respect to the central surface, lower bearing surfaces, which are inclined with respect to the upper bearing surface and with respect to the central surface, being provided below each of the upper bearing surfaces, and a base surface which is parallel to the central surface,
- wherein an imaginary first straight line which is parallel to the central surface, an imaginary second straight line which is parallel to the upper bearing surface and an imaginary third straight line which is parallel to the lower bearing surface form, as viewed in cross-section through the profiled-rail guide, a triangle in which an angle alpha is formed between the first and second straight lines and in which an angle gamma is formed between the first and the third straight lines,
- wherein the angle alpha has a value from 10° up to and including 45° and in that the angle gamma has a value from 20° up to and including 55° .
A hydrostatic profiled-rail guide, comprising:
- a guide carriage having a base and two limbs extending from the base which are each angled inward towards a guide rail, engageable around the guide rail and hydrostatically mountable on the guide rail,
- the base having, on one side, a mounting surface and, on the other side, two upper bearing surfaces which are inclined with respect to the mounting surface and which extend along a longitudinal axis of the profiled-rail guide, and a lower bearing surface, which is arranged so as to be inclined with respect to the upper bearing surface and with respect to the mounting surface, being provided below the upper bearing surfaces,
- wherein an imaginary first straight line which is parallel to the mounting surface, an imaginary second straight line which is parallel to the upper bearing surface and an imaginary third straight line which is parallel to the lower bearing surface forming, as viewed in cross section through the profiled-rail guide, a triangle in which an angle alpha is formed between the first and second straight lines and in which an angle gamma is formed between the first and the third straight lines ,
- wherein the angle alpha has values from 10° up to and including 45° and in that the angle gamma has values from 20° up to and including 55° .
