Abstract
The utility model discloses a ball screw nut assembly with a flange, comprising a nut, a screw rod, a sealing ring and balls, wherein a spiral ball rolling track is arranged on the outer circumferential surface of the screw rod; a spiral ball rolling groove is arranged on the inner circumferential surface of the nut; after the screw rod and the nut are sheathed, the ball rolling track and the ball rolling groove form a rolling channel for the rolling of a plurality of balls; the rolling channel is divided into a plurality of sections by a plurality of ball returning devices; the balls circularly roll between the front and rear ball returning devices; and the sealing ring is positioned at two ends of the nut to seal two ends of the rolling channel. The ball screw nut assembly with the flange is characterized in that the flange which is fixedly connected with the nut is arranged at one end of the nut. The flange and the nut are used as a whole to be directly matched with a workpiece so that the matching error is decreased, the screw rod and the nut run stably and the service life of the screw rod and the nut is prolonged; and a connection hole which is fixedly connected with the assembled workpiece in axial or longitudinal direction is arranged on the flange, so that the dismounting is convenient and materials for assembling a nut seat cover are saved.
Description
Technical field
The utility model relates to a kind of ball-screw nut, particularly a kind of flanged (FLGD) ball-screw nut assembly.
Background technique
Plain edition ball-screw nut in the market is with after leading screw cooperates, in supporting with various device, the leading screw two ends are fixed on earlier in the rotatable mechanism, and nut will cooperate with the cover for seat in the supporting workpiece, rotatablely move by leading screw, drive nut and workpiece and move forwards or backwards.Because cover for seat internal diameter and nut external diameter are tolerance fit, can produce certain mismatch error, cause nut in rotation, to produce vibration and instability like this, influence the precision of work, thereby shorten the working life of ball-screw nut, and when set screw nut, need mix corresponding cover for seat in addition, and increased the material use amount, also increased the cost of product.
Summary of the invention
The utility model provides a kind of flanged (FLGD) ball-screw nut that need not to join in addition corresponding cover for seat, can avoid influencing because of the error that cover for seat cooperates the working life of feed screw nut.
A kind of flanged (FLGD) ball-screw nut assembly, comprise nut, leading screw, seal ring and ball, described leading screw outer circumferential face is provided with spiral helicine ball rolling rail, the nut inner peripheral surface is provided with spiral helicine ball rolling groove, ball rolling rail and ball rolling groove form a roll channel that holds a plurality of balls rollings behind leading screw and the nut fit, ball rolling rail and ball rolling groove form one and hold the roll channel that a plurality of balls roll, roll channel is divided into several sections by several ball-returning devices, ball is circulating rolling between the ball-returning device of front and back, seal ring is positioned at the closed at both ends of the two ends of nut with roll channel, it is characterized in that described nut one end be provided with one with the affixed flange of nut.
The beneficial effects of the utility model are, flange and ball-screw nut are an integral body, can directly cooperate with workpiece, have reduced mismatch error, improved installation precision, make feed screw nut the time can move stably in running, thus the working life of having improved feed screw nut greatly, and have on the flange can be affixed with workpiece attachment hole, no matter axial or vertical assembling can, easy accessibility when having saved the rigger, has been saved the material of joining the nut cover for seat in addition.
