Precision single-bearing set roller guide wheel and low profile positioning stages using the same

A roller guide wheel contains a single set of spherical bearings and is constructed with a precision outer race machined into the guide wheel interior and an inner race formed by the surfaces of two conically-tapered set screws that affix the roller guide wheel within a housing made part of a stage slider. The roller guide wheel, which contacts a rail on one side of the stage body and exhibits a non-nutating axis of rotation, serves as way for the translating slider. The way on the opposing side of the slider is a set of v-groove contacts that make sliding contact with a rail on the corresponding side of the stage body. A flexure is machined into the slider permitting preload of the slider contacts points with the rails. The stage geometry permits a large slider through-hole and the use of alternative way mechanisms with the roller guide wheel.

The load binder includes a housing with an internal gear mechanism and a connector mechanism operatively engaged with the gear mechanism and extending outwardly from the housing. A high speed first driveshaft and a lower speed second driveshaft on the load binder are selectively individually actuated to effect movement between first and second end linkages of the connector mechanism. The first driveshaft effects movement between the first and second end linkages at a first speed and the second driveshaft effects movement between the end linkages at a lower second speed. Rotation of either of the first or second driveshafts actuates the connector mechanism, changing the distance between the first and second end linkages, and thereby changing the tension in the tie-down.
