Embodiment Construction
[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0018] figure 1 In order to convert the linear motion into a rotary motion mechanism, it is composed of a rolling spline pair and a rolling helical pair arranged in series; the rolling spline pair is composed of an outer sleeve 2, a middle sleeve 4, an inner sleeve 1, and a steel ball 5. Its The purpose is to restrict the inner sleeve 1 to move axially; the rolling screw is composed of a spiral sleeve 6, a middle sleeve 8, an inner sleeve 1, and a steel ball 5. Its function is to drive the spiral sleeve when the inner sleeve 1 moves axially. 6 turn. Straight grooves and spiral grooves are distributed on the inner sleeve 1 . The outer sleeve 2 of the rolling spline is fastened on the cylinder block through the outer cylinder, flange and screw 3; the thrust bearing 7 restricts the helical sleeve 6 from moving axially, but can only rotate; the ...
