发明名称 BALL SCREW TRANSMISSION FOR CONVERTING AN AXIAL MOVEMENT INTO A ROTATIONAL MOVEMENT AND VICE-VERSA FOR MACHINE ELEMENTS
摘要 <p>A helical ball gearing for converting axial or linear motion into rotary motion and vice versa. In a helical ball gearing including a rotor having at least one helical groove, a non-rotatable but axial displaceable shaft having at least one helical groove and being disposed at least partly within the rotor, a plurality of balls disposed in the helical grooves between the rotor and shaft, and a guide for the balls serving as a bearing for the balls, the guide being elastically resilient in the axial direction. The guide thereby allowing the balls to shift axially within the grooves so as to reduce wear on the grooves. The guide may be a helical spring.</p>
