Definitions
- the rolling bodies are formed of a plurality of alternating balls 31 and rollers 32 in each of the continuous paths 13, 14.
- the diameters d2 of rollers correspond substantially to the diameter dl of the balls, while the length h of the rollers is slightly less than their diameter d2 and thus also than the diameter dl of the balls.
- the cylindrical surfaces of the rollers are illustrated by means of lines parallel to the roller axis.
- the rollers 32 thus roll on the lower track groove faces 9, 10 and the upper car groove faces 23,25 when the car 2 is displaced along the track while being subjected to a load in the direction shown by the arrow P.
- the balls 31 also roll on the said faces.
- the track car 52 is U-shaped and the continuous paths 63,64 are provided in the respective legs.
- the continuous paths 63, 64 correspond essentially to the continuous paths 19,20 described above with reference to Figs. 1 and 2 with the exception that they are arranged in a plane forming an angle of 45 ° with the longitudinal mid-plane L of the track 51 and the car 52.
- Each of the continuous paths 63,64 thus has a N-shaped car groove 67,68 arranged opposite the respective track grooves 57, 58.
- the dimensions of the balls 31 and the rollers 32 are the same as described above with reference to Figs. 1 and 2, and the rollers are orientated in the same manner as the rollers in Figs. 3 and 4, ie the cylindrical surfaces thereof roll on the groove faces 61,74;62,76 when the car 52 is displaced along the track 51 while being subjected to a load in the direction of the arrow T, which is the main load direction.
