The invention relates to a flexible transmission mechanism, a reciprocating mechanism and a lifting device. High-precision transmission can be achieved, and the reliability of motion is ensured. The reciprocating mechanism comprises a rack, an objective table, a driving part, a driven part, a guide mechanism and the flexible transmission mechanism, the guide mechanism at least comprises a guide rail sliding block mechanism, the objective table is installed on a sliding block of the guide rail sliding block mechanism, and the flexible transmission mechanism is connected with the driven part andthe objective table. During actual application, the driving part is used for driving the driven part to move in the axial direction, the driven part is used for driving the objective table to move ona linear guide rail of the guide rail sliding block mechanism in the Z direction through the flexible transmission mechanism, and the flexible transmission mechanism can drive the objective table tomove in the X direction and the Y direction relative to the driven part. In this way, even if the guide rail and the driven part doing linear motion are not parallel, smooth operation of the mechanismcan be guaranteed.
本发明涉及一种柔性传动机构、往复运动机构及升降装置,能够实现高精度的传动,保证运动的可靠性。本发明的往复运动机构包括机架、载物台、原动件、从动件、导向机构和柔性传动机构,所述导向机构至少包括一组导轨滑块机构,且所述载物台安装在导轨滑块机构的滑块上,所述柔性传动机构分别连接从动件和载物台。实际应用时,所述原动件用于驱动从动件沿轴向运动,且所述从动件用于通过柔性传动机构驱动载物台在导轨滑块机构的直线导轨上沿Z向移动,而所述柔性传动机构能够带动载物台相对于从动件沿X向和Y向移动。这样做即使导轨和做直线运动的从动件存在不平行的问题,也能够确保机构顺畅运行。
