摘要： This invention relates to improvement of a ball screw unit in which a nut member meshes with a screw shaft via a plurality of balls circulating endlessly. The balls are disposed freely rotatably in line at a predetermined interval in a ball arranging member formed in a belt-like shape. If a relative rotation occurs between the nut member and screw shaft, the balls circulate in the infinite circulation path with the ball arranging member. Guide pieces are projected to both sides of the ball arranging member and guide grooves for accommodating each of the guide pieces are formed along the entire circumference of the infinite circulation path. Therefore, the ball arranging member is introduced by the guide grooves and circulates in the infinite circulation path without being fluttered.

摘要： A ball screw unit comprising a screw having a helical ball rolling groove on the outer peripheral surface thereof, a nut assembly having a load zone formed of a helical load rolling groove opposing to the ball rolling groove of the screw and a no-load zone forming a ball endless track by establishing communication between the starting end and the terminating end of the load zone, a number of balls rolling within the endless track of the nut assembly and a ball coupler comprised of coupling members for retaining the balls to rotate in their aligned state, wherein guide grooves for guiding the coupling members of the ball coupler are formed in the load zone of the ball endless track such that the coupling members of the ball coupler are moved by each of the balls in the no-load zone of the endless track while each of the balls is guided to move by the coupling members of the ball coupler in the no-load zone of the endless track, and guide sections for guiding the ball coupling members of the ball coupler along the progressing direction of the balls moving in the load zone are provided at least at both ends of the no-load zone near the load zone, respectively. Thus, according to the present invention, the delivery and reception of the balls are performed smoothly between the load zone and the no-load zone of the ball endless track to thereby achieve the smooth circulation of the balls.

摘要： The present invention relates to a ball chain used by being integrated to, for example, a ball endless track of a linear guide device for endless sliding in which a number of balls are arranged in one row and rollably held, particularly to a ball chain which is most pertinent to a linear guide device having a ball rolling groove in a shape of a Gothic arch. According to the ball chain, the number of balls are arranged in one row and the balls are held rollably, each of the balls is pinched by a pair of spherical seats and the spherical seats are connected to each other by flange portions to thereby constitute a ball holding unit and a plurality of the ball holding units are connected in a shape of a rosary by a flexible connecting portion. Further, the spherical seats and the flange portions are molded by a resin material whereas the connecting portion is formed by a material having a tensile strength larger than that of the resin material.
