Outer a pair of angular contact ball bearings (15) are fixedly mounted on bearing block (3), and spring dead plate (13) is fixed by adjusting screw (2)
On bearing block (3), compression spring (11) is arranged on the bearing (ball) cover and spring dead plate (13) of ball-screw (10) support end
Between, workbench (4) respectively with the sliding block (9) on guide rail (5) and the nut (14) on ball-screw (10)
Coordinate, guide rail (5), bearing block (3) and motor cabinet (7) are arranged on cross slide (1).
The drive end of ball-screw (10) is fixed using two angular contact ball bearings (15) mutually back to installation.
The pretightning force of angular contact ball bearing (15) obtains compression spring (11) generation deformation by screwing adjusting screw (2)
.
Three adjusting screws (2) are in equilateral triangle, to ensure spring dead plate (13) and cross slide (1) upper surface
Perpendicularity.
Thermal deformation and thermal stress are produced during feed system long time continuous working, when thermal stress overcomes bearing pre-fastening
When, the compression spring (11) is further compressed, it is ensured that the positioning precision of ball-screw (10).
Compared with prior art, the invention has the advantages that：
Using adjusting screw and compression spring combination design, adjusting screw is set to three and not conllinear, so that compression bullet
Spring axis is parallel with cross slide upper surface；Turning adjusting screw makes the axial pretightening of spring-compressed guarantee angular contact ball bearing
Power；When thermal deformation occurs for ball-screw, its thermal stretching makes compression spring further deform upon, control Machine Tool Feeding System positioning
Error and resetting error；Ball-screw right-hand member support angular contact ball bearing uses back-to-back mounting means, prevents thermal change
Shape causes the generation of the stuck breakoff phenomenon of bearing, prevents the loss of machine finish.
