The invention relates to the technical field of lifting equipment, and discloses a high-precision ball screw elevator which comprises an elevator body, a worm is arranged on the lower portion in the elevator body, a worm gear is connected to one side of the worm in a meshed mode, a nut is connected to the upper portion of the worm gear, and the nut and the worm gear are fixed. A ball screw penetrates through the middle of the worm wheel and the middle of the nut, the ball screw is in threaded connection with the worm wheel, the upper end of the ball screw penetrates through the machine body and is provided with a lifting limiting mechanism, the lower end of the ball screw extends out of the machine body and is fixedly provided with a flange, and the outer wall, between the flange and the machine body, of the ball screw is wrapped with a telescopic dust cover. According to the zero-clearance ball screw axial assembly, worm pretightening force is provided through the elastic washer, enough tension is kept, the worm can normally operate in the zero-clearance state, the zero-clearance ball screw axial assembly does not generate large deformation within the normal stress range, and therefore reciprocating lifting displacement of a ball screw is finer, and the standard of high displacement precision is achieved.

    本发明涉及升降设备的技术领域,公开了一种高精度滚珠丝杠升降机,包括机体,在所述机体内的下部设置有蜗杆,所述蜗杆的一侧啮合连接有蜗轮,所述蜗轮的上部连接有螺母,所述螺母与蜗轮相固定,在所述蜗轮、螺母的中部贯穿设置有滚珠丝杠,所述滚珠丝杠与蜗轮螺纹连接,所述滚珠丝杠的上端贯穿机体且设置有升降限位机构,所述滚珠丝杠的下端延伸出机体且固定有法兰,所述法兰与机体间的滚珠丝杠外壁上包覆有伸缩防尘罩。本发明通过弹性垫圈提供蜗杆预紧力并保持足够的张力,使蜗杆在零间隙时能正常运转,在正常受力范围内“零间隙滚珠丝杠轴向组件”不产生大的变形,从而使滚珠丝杠的往复升降位移更加精细,以达到位移高精度的标准。
