Abstract

一种滚轮丝杆,由丝杆,滚轮,轴承和轴承座及销钉组成,丝杆圆周上均布有滚轮,滚轮两端由轴承定位于轴承座中,轴承座由销钉固定,均布的滚轮在轴向上为等高度差平行分布并与长丝杆螺牙啮合。在运行时,丝杆的旋转带动啮合的滚轮旋转平移,滚轮由两端的滚动轴承支撑旋转,并带动轴承座的平移。此种丝杆可以广泛用于螺杆驱动的或滚珠丝杆传动的直线运动机构上,如机床,木工机械,医疗及自动化设备上。
The utility model relates to a roller wheel screw rod which is composed of a screw rod, a roller wheel, a bearing, a bearing block and a dowel; roller wheels are uniformly distributed at the circumference of the screw rod, two ends of the roller wheel are located in the bearing block by the baring, the bearing block is fixed by the dowel, the roller wheels which are uniformly distributed are distributed in parallel with equal height difference along the axial direction and are meshed with spiral teeth of a long screw rod. When in operation, the rotation of the screw rod drives the meshed roller wheels to shift rotationally, the roller wheels are supported and rotate by rolling bearings at two ends and drive the bearing block to shift. The screw rod can be widely applied to a linear motionmechanism driven by the screw rod or a ball screw rod, such as machine tools, wood working machinery, medical treatment and automation equipment.
