The _ fee of the Hai-Spirit B, the annular pre-pressure two =: the smoothness of the displacement, and the long-term friction caused by =, Xian consumption, in addition, the second nut B is required for use == first The material of the more rigid material y, so the friction between the two annular precast tablets 10 and the two nuts B and the friction loss is more difficult to reduce 'is also purchased. The invention aims to provide a ball screw cup with an adjustable dragon device, and a convex portion on each of the two annular pre-pressing sheets disposed on the two nuts, and the convex portions are respectively provided. Pressing against the two wedge blocks, and then wrapping around the periphery of the two molds with the tightening member, since only the two wedge blocks are in contact with the two annular pre (four), the frictional energy (4) can be reduced, and the lifting can be improved. Smooth operation and reduced wear. Therefore, the ball screw with the adjustable preloading device of the present invention comprises a snail 200844349 talent, a nut, a second ring g η _ _ on the screw and a nut and is located at the two screw two:::_ respectively _ ^ 曰 1 η 各 各 幵 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预 预The two wedges are:: 'the outer side of the direction of the cane and the limit, the tightening member corresponding to the radial position of the two nuts can adjust the controllable spacing of the two wedge blocks and change the preference - the second can be adjusted The pre-sampling of the nut is the directional spacing, whereby the ball screw of the present invention having the adjustable pre-pressing device achieves radial displacement by sliding between the convex portion of the annular pre-pressing piece, Therefore, there is friction between the 亥海_ wedge block and the convex portion of the two annular pre-(four), for example, the low-friction coefficient lli is used to reduce the energy caused by the friction for the two wedge-shaped block and the two-circle pre-compression piece (4), Moreover, the adjustment pre-action can be made smoother, and the abrasion caused by friction can be reduced more; and the invention has the following: The ball screw can also apply lubricating grease between the two blocks and the: paste convex portion, and can reduce the friction between the convex portions. A plurality of concave wire locks are formed on the end faces of the convex portions of the 200844349 In addition, the belt may be a tooth. In addition, in the two annular pre-pressing groove, the grooves may be filled with lubricating grease and the tightening member may be an e-lock and tightly locked by the threaded rod. MODES OF THE INVENTION The ball screw of the present invention has an adjustable dragon device, as shown in FIG. 5, which comprises: a port screw 30; two nuts 40 are respectively screwed on the screw 3 (), and the two screws The caps 4 are adjacent to each other; a %-shaped pre-pressing piece 50 is respectively sleeved on the screw 3〇, and a second annular pre-pressing piece 50 is mounted on the second nut 4G and located between the two screws. Each of the annular pre-pressing sheets 5G is further formed with a plurality of cymbals 51, and each of the convex portions 51 has an inclined end surface 52. In this embodiment, the annular pre-pressing sheets 50 have two (four) 5 b and the two convex portions 51 are respectively located. In the opposite direction of the side faces of the annular pre-pressing sheets 50 in the axial direction; the two wedge-shaped blocks 60 are opposed to each other and respectively disposed between the convex portions 51 of the two annular pre- 50s' The two wedge-shaped blocks 6Q are in contact with the end faces 52 of the convex portions 51 with the inclined surfaces 61 on both sides in the axial direction. In this embodiment, the two-shaped blocks 6G A correspond to the two annular pre-compression sheets 5Q. Shaped to form an arc 200844349 shape; and side, this, and in the radial direction of the two-shaped block 6〇, the outer '°H beam tightening member 70 is sleeved outside the two wedge-shaped block 6〇 to limit the shape block 60 is radially outwardly displaced, and the tightening member 7() is composed of two buckles 71 which are locked by screws 72. The ball screw with the adjustable preloading device of the present invention adjusts the pre-emptive force , ° Zhou Zheng ° Hai Shu Qin, the member 70 corresponding to the radial position of the second nut 40 to adjust the radial spacing of the two wedge blocks 60, and synchronous adjustment of the axial spacing of the two annular calendar 5 ,, In this way, the pre-pressure of the second nut 40 is adjusted. In this embodiment, as shown in FIGS. 6 and 7, the screw 72 of the tie member 70 is loosened to increase the tightening member 7 The radial spacing of the two c-pins 71 'the two wedge-shaped blocks 6G can increase the radial spacing therebetween, and the two annular pre-compression sheets 5 are relatively reduced. The axial spacing and synchronously reduces the pulling pitch of the two nuts 4'. Conversely, the screw 72 that tightens the tightening member 7G reduces the radial spacing of the tightening member 70 and the second C-clip 71. The block 6〇 can reduce the radial spacing therebetween, and the axial spacing of the two annular pre-pressing sheets 50 is increased to increase the axial spacing of the two nuts 4 (), thus changing the two nuts 4G. The axial spacing can change the pre-pressure of the second nut 4(). Due to the ball screw of the present invention having an adjustable preloading device, only the two die 10 200844349 shaped block 60 I _ π, the convex portion 51 of the wide % shaped pre-pressing piece 50 will be produced for the two wedges ^, the material, the two-green two-shaped pre-pressed sheet 5 〇 uses a low coefficient of friction, which is enough to reduce the energy waste caused by friction, and can be more pressure-sensitive, and can reduce the wear caused by friction; In addition, the lubricating oil can be applied between the two wedge blocks 6Q and the two annular pre-pressing pieces 5q, and the two wedge-shaped blocks 6q and the convex portions 51 can be reduced. The convex portions η of the two annular dragon pieces 5Q can also form a recessed groove on the end surface 52, and the grooves can be used for storing the grease to make the lubrication effect last longer, and the tightening member 7G can also be a belt. The rack is tightly locked, and the function of adjusting the radial position of the tightening member 7G corresponding to the two nuts 4 is obtained. In summary, the present invention is characterized in that: the ball screw of the adjustable pre-(four) type is provided with a second nut on the screw, and two annular pulp pieces, two wedge pieces and a tightening are arranged between the two positions. And adjusting the radial spacing of the two horizontal blocks by the tightening member to change the axial spacing of the two annular sheets, thereby adjusting the pre-pressure of the ball screw to eliminate the backlash between the nut and the screw. 200844349 • [Simple description of the diagram] Figure 1 shows a schematic diagram of the assembly of the adjustable preload structure on the ball screw.
