Screw drive method and apparatus |
摘要 |
A method and apparatus for operating a screw drive apparatus. The apparatus may include a threaded rod having a helical thread, a nut disposed about the threaded rod and having a load-bearing channel aligned with and radially outward from the helical thread, and a plurality of balls between the helical thread and the load-bearing channel. The apparatus may further include a housing with at least one support bearing having an inner race coupled to the nut and an outer race coupled to the housing and rotatable relative to the inner race. A retaining member is removably and adjustably coupled to the nut to apply an adjustable force against the support bearing in a direction generally parallel to a longitudinal axis of the threaded rod.
