摘要： There is provided a ball screw that is used to apply a preload to balls and that has a configuration of achieving a balance between the cooling efficiency and ease of assembly and disassembly. To this end, the ball screw includes a screw shaft, and a plurality of nuts movable relative to the screw shaft in an axial direction. Each of the nuts includes flow channels, which are cooling mechanisms and which respectively serve as independent channels to allow a cooling medium to pass through them. These flow channels are provided symmetrically with respect to a space between the nuts, and are configured so that the cooling medium can independently circulate in each of the nuts.

摘要： A fixed torque preload piece is positioned between two nuts of a ball screw, the preload piece is formed with through hole located in an axial direction of the two nuts for receiving at least two steel balls. Two terminal openings of each of the through holes are defined in the surfaces of the preload piece facing the two opposite nuts. Three radial threaded holes are formed in the outer periphery of the preload piece, and the threaded holes are vertical to and in communication with the through holes. An adjusting member, an elastic member and an adjusting screw are received sequentially in the respective threaded holes. The steel balls in the through holes are pushed against the two nuts by the arc-shaped abutting surface of the adjusting member, the pushing of the steel balls can produce an adjustable preload, and can absorb the sudden increase of the pressure effectively, thus obtaining the objective of the present invention of outputting torque stably.

摘要： An electric power steering apparatus for converting rotation of a steering assist motor into movement of a steering shaft in the axial direction thereof in accordance with steering operation using a ball screw mechanism wherein a female thread groove formed around an inner circumference of a rotating cylinder rotated around the axis thereof by the motor and a male thread groove formed around an outer circumference of the steering shaft are screwed with each other via a plurality of balls. The portions, where the both thread grooves contact with the balls, are formed in a circular arc shape, respectively, and the curvature of the female thread groove is made smaller than that of the male thread groove. Hence, the ball screw mechanism wherein skew occurrence between the ball and both the thread grooves is prevented and the dimensional errors of both the thread groove are decreased is realized.

摘要： A screw drive with rolling elements, optionally a ball screw drive, includes a screw spindle with a spindle axis and a double nut running on the screw spindle, with two separately formed single nuts which are substantially rigidly joined in the direction of the axis of the spindle. In order to set a desired play or bias relative to the screw spindle, the two single nuts can be turned continuously about the axis of the spindle relative to each other and fixed in any relative rotary position corresponding to the desired play or bias. According to the invention, a first of the two single nuts or an intermediate element joined thereto and arranged between the two single nuts has at least one peripheral section pressed into an associated aperture in one of the single nuts. In one embodiment, the intermediate element is an annular disk that is arranged orthogonally to the spindle axis.

摘要： Varying fluid pressure varies the thickness of an elastic spacer between ball nuts of the ball screw. The spacer thickness determines opposed axial forces applied to the ball nuts. During a high-speed excursion of the screw, pressure in the elastic spacer is reduced, thus reducing friction between the ball nuts and the screw. When the screw is being fine positioned for precise operation, pressure in the elastic spacer is increased, thereby urging the ball nuts apart to eliminate play in the ball screw.
摘要翻译：不同的流体压力会改变滚珠丝杠球螺母之间弹性垫片的厚度。间隔件厚度确定施加到球螺母的相反的轴向力。在螺杆的高速偏移期间，弹性间隔件中的压力减小，从而减小滚珠螺母和螺钉之间的摩擦。当精确定位螺钉精确操作时，弹性垫片中的压力增加，从而推动球形螺母分离，以消除滚珠丝杠的冲击。
