Embodiment Construction
[0024] This embodiment is a comprehensive performance test bench for a planetary roller screw pair.
[0025] refer to Figure 1 to Figure 6, the comprehensive performance test bench of the planetary roller screw pair in this embodiment consists of a test bench bottom plate assembly 1, a drive assembly 2, a coupling 3, a test assembly 4, a threaded push rod nut 5, an internal force rod 6, and a hydraulic loading assembly 7. The internal force rod nut 8, the hydraulic loading base 9, the hydraulic loading rear base 10, and the hydraulic cylinder fixing screw 11 are composed. The drive assembly 2 is used to drive the planetary roller screw pair to drive the screw to rotate. Test assembly 4 is used to install different types of planetary roller screw pairs. The hydraulic loading assembly 7 is used to provide load for the planetary roller screw pair to simulate its actual working condition. The bottom plate assembly 1 of the test bench is used to support parts connected to the t...
