Definitions

  • the slide guide member is formed of a rigid baseplate and a T-shaped bed having an upright member and a cross member being supported by the baseplate.
  • a rectangular longitudinal slot is located in the top surface of the bed and along both side surfaces.
  • the slide member is formed with rectangular longitudinally extending bearing feet which project into and are received by each of the slots on the slide guide member.
  • a pair of bearing chambers supplied with hydraulic fluid under pressure are arranged on oppositely located surfaces of each of the bearing feet to produce oppositely directed compressive forces on the projecting bearing feet so that the slide will be bilaterally journaled on the guide member in two separate directions which are oriented at right angles to each other, thereby preventing bending moments in the slide and slide guide combination and allowing for lightweight rigid construction.
  • the invention relates to a hydrostatically journaled slide and slide guide, in which the slide has a substantially C-shaped cross section the inside of which cooperates with the slide guide.
  • the slide is bilaterallyjournaled in two directions which extend at right angles to each other. Bearing chambers are therefore provided on surfaces of the slide cooperating with the slide guide. The chambers communicate through a restriction with a supply for hydraulic medium under pressure.
  • the slide be constructed from a number of separate elements which are united by means of connection members to form one assembly.
  • the manufacture of this slide is very simple and accurate. This construction is possible because the forces on the slide are fully balanced.
  • a hydrostatically journaled slide and slide guide as claimed in claim 1 wherein the parts of the slide guide which are situated between slot-shaped recesses ensuring a bearing and viewed in the cross section of the guide, are directed mutually at right angles and are of square shape, all the recesses having the same depths and the bearing chambers of bearing feet fitting in said recesses being situated at the same distance from the outside of the recesses.
