摘要： The threads of a nut on a multithreaded, high helix lead screw are formed by disposing a nut over a lead screw where the center hole of the nut is larger than the threads of the lead screw. Polymer material is filled into the space between the nut and the lead screw and cured to form a high helix, multithreaded nut which has threads complimentary to the threads of the lead screw.

摘要： A spiral wound abrasive belt is formed from an abrasive media including a plurality of webs. The webs of the abrasive media may include coated abrasives joined by splicing media or other suitable joining material. Alternatively, the webs may include individual single or multiple layers that form a coated abrasive simultaneously along with the spiral belt without the use of additional joining material. A method of forming the spiral belt includes draping the abrasive media over a fixed hub at an angle to form the spiral belt while abutting the edges of the outermost web and overlapping the outermost web and adjacent web or webs. Heat and pressure may be applied to the joined edges to form a strong bond along the spiral seam. Another method includes introducing the webs forming the abrasive media at an angle and draping the webs over a fixed hub. The abrasive media may then be passed around an adjustable hub that provides tension in the spiral belt while allowing for different circumferentially sized belts. Continuous feeding of the input abrasive media or webs will result in a spiral belt of ever increasing width that may subsequently be slit to a desired width.

摘要： A high helix, multi threaded screw shuttle transfer assembly (10) for transferring high load devices at high speeds includes a screw (18) having threads (23). Standoff brackets (26) and bearing housing (36) rotatably support and journal the ends (20,22) of the screw (18). A drive motor (50) connected by a belt (52) to a pulley (48) on the screw (18) rotates the screw (18). A nonrotatable nut (54) having threads (56) coactive with the threads (23) of the screw (18) travels along the longitudinal length of the screw (18) during rotation thereof. The assembly (10) is characterized by the threads (23,56) of the nut (54) and the screw (18) each being high helixed and multithreaded. The threads (56) of the nut (54) are formed about the threads (23) of the screw (18) for providing multipoint full thread contact completely about the screw (18) and minimizing tolerances between the threads (23) of the screw (18) and the threads (56) of the nut (54) to move the nut (54) at high speeds between the ends (20,22) of the screw (18). Further, a method of forming the threads (56) of the nut (54) on the lead screw (18) of the nut drive and lead screw assembly (10) is provided.
