Rotary splines are special bearing sleeves installed on the outer diameter of the splined outer tube to allow rotational motion. By rotating or stopping the outer tube, the mechanism can perform two modes of motion (rotation and linear) using a single axis.
The rotary spline is a mechanism that allows for both rotational and linear movement using a single shaft. It consists of a spline shaft, spline sleeve, bearings, and a spring ring. The spline shaft, made of high-precision steel, has precise keyways on its outer surface to allow for the movement of the bearings. The spline sleeve is a lightweight and wear-resistant material that is fitted onto the spline shaft to reduce friction and wear.
During operation, the bearings roll in the keyways of the spline shaft, while the spring ring ensures close contact between the bearings and the shaft, enabling smooth rotation. In order to prevent the bearings from dislodging during movement, the spline sleeve is equipped with anti-detachment devices.
The structure of the rotary spline is complex and relatively expensive to manufacture. It requires high precision in machining and assembly. However, it offers advantages such as high accuracy, long life, and high transmission efficiency. The unique design of the rotary spline minimizes friction and wear, ensuring precise transmission. Additionally, components such as bearings and spring rings can be replaced, simplifying maintenance.
The rotary spline is a highly precise and efficient mechanical transmission device. Its unique structure provides accurate transmission with long service life and low maintenance costs. However, the manufacturing cost is higher, and there are strict requirements for manufacturing and installation. It is suitable for various devices such as horizontal multi-joint robotic arms, industrial robots, automated loading machines, laser processing machines, conveyors, and machining centers with ATC devices.
