Abstract
A translation table that has a spring biased dovetail bearing. The table includes a first element with a dovetail groove and a second element with a dovetail bearing located in the groove. The table further includes one or more springs that press the bearing into the groove. The spring force may be selected to eliminate lateral movement between the first and second elements while minimizing the friction of the bearing. The spring force may be varied by a screw(s) that engages the spring(s).
Claims19
A translation table, comprising:
- a first element that has a dovetail groove;
- a second element that can move relative to said first element, said second element having a dovetail bearing that can slide along said dovetail groove;
- a spring that exerts a force onto said dovetail bearing to press said dovetail bearing into said dovetail groove;
- and,
- a screw that is pressed into said spring.
A translation table, comprising:
- a first element that has a dovetail groove that extends along a radial top surface;
- a second element that can move relative to said first element, said second element having a dovetail bearing that can slide along said dovetail groove, said dovetail bearing having a radial bottom surface that is adjacent to said radial top surface of said first element;
- a spring that exerts a force onto said dovetail bearing to press said dovetail bearing into said dovetail groove;
- and,
- a screw that is pressed into said spring can vary the force exerted by said spring onto said dovetail bearing.
A method for adjusting a pressure of a dovetail bearing located in a dovetail groove, comprising:
- varying a spring force of a spring that exerts a force onto the dovetail by turning a screw and changing a length of the spring.
A translation table, comprising:
- a first element that has a dovetail groove;
- a second element that can move relative to said first element, said second element having a dovetail bearing that can slide along said dovetail groove, said dovetail bearing having a slot;
- a spring that is seated in said slot of said dovetail bearing and exerts a force to press said dovetail bearing into said dovetail groove.
