The invention discloses a recirculating ball steering transmission shaft, and relates to the technical field of steering transmission shafts, the recirculating ball steering transmission shaft comprises a ball sleeve and a ball shaft component, a ball adjusting mechanism is arranged at the left end of the ball shaft component, the ball adjusting mechanism comprises a first retainer and a guide sleeve, and at least three ball assemblies are uniformly distributed in the circumferential direction of the first retainer; and the ball shaft part is continuously rolled and adjusted relative to the axial direction of the ball sleeve through circulating rolling of the balls, the ball assembly comprises second retainers which are symmetrically arranged and guide rails which are symmetrically arranged on the two sides of the guide sleeve rail groove, and the balls are arranged on the guide rails. A full-rolling structural design is adopted, axial continuous rolling adjustment of the ball shaft component relative to the ball sleeve is achieved through circulating rolling of the balls, friction is small, noise is low, rolling is smooth, telescopic resistance between the ball shaft and the ball sleeve is reduced, the service life of the steering telescopic shaft is prolonged, and performance is safe and reliable.

    本发明公开了循环球转向传动轴,涉及转向传动轴技术领域,包括滚珠套、滚珠轴部件,所述滚珠轴部件左端设置有滚珠调节机构,所述滚珠调节机构包括第一保持架、导套,所述第一保持架周向均布设置有至少三组滚珠组件,通过滚珠的循环滚动实现滚珠轴部件相对于滚珠套轴向连续滚动调节,所述滚珠组件包括对称设置的第二保持架、对称设置在导套轨道槽两侧的导轨,所述导轨上设置有滚珠。采用全滚动结构设计,通过滚珠的循环滚动实现滚珠轴部件相对于滚珠套轴向连续滚动调节,摩擦小,噪音低,滚动顺畅,降低了滚珠轴与滚珠套之间的伸缩阻力,延长转向伸缩轴的使用寿命,性能安全可靠。
