The invention discloses a detachable ball spline type steering transmission shaft. The detachable ball spline type steering transmission shaft is characterized in that a transmission shaft body and atransmission shaft sleeve are a detachable ball spline type steering transmission shaft, the transmission shaft body is welded with one end of the transmission shaft sleeve, and a round check ring, aball retainer assembly, a special-shaped check ring and a rubber dustproof sealing ring are sequentially installed in the transmission shaft sleeve; a sealing cover is arranged at one end of the transmission shaft sleeve, a cross shaft dustproof cover is arranged at one end of the transmission shaft body, and a cross shaft dustproof cover is arranged at the other end of the transmission shaft sleeve; four rows of balls are arranged on a ball retainer, and five balls are arranged in each row; and the transmission shaft sleeve is formed by installing one end of a special-shaped steel pipe into the round check ring and then pressing a steel pipe joint into the special-shaped steel pipe in a small interference mode to fix the round check ring. According to the detachable ball spline type steering transmission shaft, the four-fairway ball retainer assembly is installed in the transmission shaft sleeve, the three-guarantee claim settlement rate is reduced, the transmission shaft sleeve is combined, the manufacturing cost is low, the service life of a product is prolonged, popularization and use are easy, detection and maintenance are convenient, and the transmission shaft is applied to the technical field of transport vehicles.

    一种可脱离滚珠花键式转向传动轴,传动轴与传动轴套是一种可脱离式滚珠花键式转向传动轴,传动轴与传动轴套一端焊接,在传动轴套内依次安装安装圆形挡圈、滚珠保持架组成、异形挡圈及橡胶防尘密封圈,在传动轴套的一端设置密封盖,在传动轴的一端设置十字轴防尘罩,在传动轴套的另一端设置十字轴防尘罩;滚珠保持架上设有四排滚珠,每排设有五个滚珠;传动轴套是由异型钢管一端装入圆形挡圈,再把钢管接头小过盈压入异型钢管内固定圆形挡圈。该发明四球道滚珠保持架组成被安装在传动轴套中,降低三包索赔率,传动轴套采用组合式制造成本低,提高产品使用寿命,易于推广和使用,方便检测及维修,应用于运输车辆技术领域中。
