Definitions

  • the present invention relates to a linear guide which is provided with a linear motor.
  • Such linear guides which can also be referred to as linear drive units or linear tables, are increasingly used, for example, in machine tool construction and in handling technology.
  • a linear guide has become known from DE 198 42 384 A1, for example, in which guide rails are arranged parallel to one another on a housing. A slide is mounted on these guide rails so as to be linearly movable.
  • a linear motor is arranged between the guide rails.
  • the linear motor comprises a primary part and a secondary part.
  • the primary part is arranged on the carriage.
  • the secondary part is arranged on the housing.
  • electromagnetic forces act between the primary part and the secondary part, which accelerate the slide relative to the housing.
  • This electromagnetic force has a component parallel to the guide rail that accelerates the carriage.
  • a second force component acts across this.
  • This shear force component acts as a normal force and has to be absorbed by the linear roller bearings. If the amount of the effective shear force component is very large, the linear roller bearings must be dimensioned accordingly.
  • the object of the present invention is to provide a linear guide according to the features of the preamble claim 1, in which this disadvantage is eliminated.
  • this object is achieved in that the primary part interacts with two secondary parts arranged on opposite sides of the primary part. Through this symmetrical arrangement of the secondary parts on both sides of the primary part, the lateral force components largely cancel each other out. A special dimensioning of the linear roller bearings with regard to this shear force component can therefore be omitted.
  • a development according to the invention provides that between the primary part and the respective secondary part effective force is effective in a plane which is arranged parallel to a plane in which the guide rail lie.
  • the two transverse force components effective transversely to the direction of movement are preferably opposite and of the same size.
  • the primary part is preferably assigned to the carriage, with the one secondary part being arranged between the one guide rail and the primary part and the other secondary part being arranged between the other guide rail and the primary part, both secondary parts being assigned to the housing.
  • the secondary part is preferably formed by a plurality of permanent magnets arranged one behind the other and parallel to the guide rails.
  • Figure 1 shows a linear guide according to the invention in perspective
  • FIG. 2 shows a section through the linear guide from FIG. 1.
  • two guide rails 1 are screwed onto a housing 2 at a parallel distance from one another.
  • a carriage 3 is mounted on these guide rails 1 by means of linear roller bearings 4 in a linearly movable manner.
  • a linear motor 5 is arranged between the two guide rails 1.
  • Figure 2 shows the structure of the linear motor 5.
  • a primary part 6 is arranged on the carriage 3. On two opposite sides of the primary part 6 are each
  • Secondary parts 7 arranged on the housing 2.
  • the secondary parts 7 are available gend formed by a plurality of one behind the other and to the guide rails 1 parallel magnets 8 arranged in parallel.
  • a force acts between the primary part 6 and the secondary parts 7, which force is effective in a plane that is parallel to a plane in which the guide rails 1 lie.
  • a shear force component F q of this force acts transversely to the guide rails 1.
  • the two shear force components F q which each act between the primary part and the respective secondary part 7, are oppositely directed and of the same size. These shear force components F q cancel each other out and do not load the linear roller bearings 4.

Abstract

L'invention concerne une glissière linéaire qui comprend deux rails de guidage (1) placés parallèlement l'un à l'autre sur un bâti (2), un coulisseau (3) logé mobile linéairement sur les rails de guidage (1) au moyen de paliers à roulement linéaires (4), ainsi qu'un moteur linéaire (5) placé entre les rails de guidage (1) et présentant une partie primaire (6) et une partie secondaire (7). La glissière linéaire selon l'invention est caractérisée en ce que la partie primaire (6) coopère avec deux parties secondaires (7) placées de part et d'autre de la partie primaire (6).
