Abstract

Abstract A hydrostatically journaled slide and slide guide combination having a slide member of substantially C-shaped cross section for cooperative engagement with a slide guide member having a partially T-shaped cross section when the C-shape of the slide is oriented at 90* with respect to the T-shape of the slide guide. The slide guide member is formed of a rigid baseplate and a Tshaped 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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 240 words
A hydrostatically journaled slide and slide guide combination comprising a slide member having a substantially C-shaped cross section and a slide guide member having a partially T-shaped cross section, said slide member being arranged for cooperative engagement with said slide member when said C-shaped slide is oriented at 90* with respect to the T-shape of the slide guide member, said slide guide member comprising a rigid baseplate, a T-shaped bed having an upright member and a crossmember, said bed being supported on said baseplate, a rectangular shaped longitudinal slot located in the top surface of said bed and a rectangular-shaped longitudinal slot located in each of the side surfaces of said bed being formed between said crossmember and said baseplate, said slide member comprising a plurality of rectangular-shaped longitudinally extending bearing feet projecting into and being received for guiding arrangement by each of the longitudinal slots of said slide guide member, at least a pair of bearing chambers provided on oppositely located surfaces of each of said rectangular bearing feet, and means for supplying hydraulic medium under pressure through a restriction to each of said bearing chambers so as to produce oppositely directed compressive bearing forces on the projecting bearing feet of the slide, whereby said slide member will be bilaterally journaled on said slide guide member in two separate directions oriented at right angles to each other to thereby prevent occurrence of bending moments and permit rigid lightweight construction.
Claim 2
Dependent Claim 240 words
A hydrostatically journaled slide and slide guide combination comprising a slide member having a substantially C-shaped cross section and a slide guide member having a partially T-shaped cross section, said slide member being arranged for cooperative engagement with said slide member when said C-shaped slide is oriented at 90* with respect to the T-shape of the slide guide member, said slide guide member comprising a rigid baseplate, a T-shaped bed having an upright member and a crossmember, said bed being supported on said baseplate, a rectangular shaped longitudinal slot located in the top surface of said bed and a rectangular-shaped longitudinal slot located in each of the side surfaces of said bed being formed between said crossmember and said baseplate, said slide member comprising a plurality of rectangular-shaped longitudinally extending bearing feet projecting into and being received for guiding arrangement by each of the longitudinal slots of said slide guide member, at least a pair of bearing chambers provided on oppositely located surfaces of each of said rectangular bearing feet, and means for supplying hydraulic medium under pressure through a restriction to each of said bearing chambers so as to produce oppositely directed compressive bearing forces on the projecting bearing feet of the slide, whereby said slide member will be bilaterally journaled on said slide guide member in two separate directions oriented at right angles to each other to thereby prevent occurrence of bending moments and permit rigid lightweight construction.
Claim 3
Dependent Claim 78 words
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.
Claim 4
Dependent Claim 32 words
A hydrostatically journaled slide and slide guide as claimed in claim 1 wherein the slide comprises a number of separate elements combined by means of connection members to form a unitary assembly.
Claim 5
Dependent Claim 46 words
A hydrostatically journaled slide and slide guide, as claimed in claim 1 wherein the bed of the slide guide member comprises separate elements which each have a rectangular shape and which are combined to form one assembly together with the baseplate by means of connection members.
