COMPACT LINEAR ROLLER GUIDE

摘要

The invention relates to a compact linear roller guide which makes it possible to transmit high forces and torques between a carriage (1) and a guide rail (3). The carriage (1) comprises two or more pairs of ribbed rollers (2), rotatably supported on the side walls of the carriage by means of bearings, between which the rail (3) is inserted, with a complementary cross-section, The simultaneous contact of the planar and convex surfaces of the rail (3) with the cylindrical and concave surfaces of the rollers (2) enables uniform distribution of the loads on said bearings and a compact configuration of the guide.

1. A compact linear roller guide capable of transmitting forces and high torques between a sliding carriage, defined by a longitudinal axis and a rectangular cross section, comprising a guide and transmission rail having a cross section composed of a section of rectangular area alternated with two upper and lower sections of convex area which is inserted longitudinally into the carriage, wherein said guide and transmission rail is housed between an assembly of rotational support members comprising at least one or more pairs of grooved rollers each pair of grooved rollers being supported on shanks, internal raceways and a bearing for axial and radial loads, wherein said rollers radially traverse the carriage to be inserted in a perpendicular manner into two of the facing lateral walls of the carriage.
