Ball Screw Drives (BSU) for Enhanced Precision in Motion Control

"Ball screw gears (ball screw drives) and their modifications:
- ball screw type - with ground threads of screw and nuts;
- length - up to 2000 mm; - diameter - from 16 to 125 mm (16, 20, 25,
32, 40, 45, 50, 63, 70, 80, 100, 110, 125);
- thread pitch - from 4 to 20 mm (4, 5, 6, 8, 10, 12, 15, 16, 20);
- thread profile - arched (gothic arch), radiused; - nut type - single nut with or without flange, a pair of nuts without body with preload with or without flange, a pair of nuts with preload in a prismatic body or in a cylindrical flanged body; - nut type - single nut with or without flange, a pair of nuts without body with preload in a prismatic body or in a cylindrical flanged body
housing;
- preload
- nut with backlash; nut with preload of 3%, 5%, 10% of the dynamic load;
- method of creating preload - by differential toothed meshing of nuts with the body, by differential toothed ring installed between two nuts, by installing a spacer ring between two nuts, by selective selection of ball diameters for ...
