摘要

单曲柄双摇杆式翻板机驱动机构，实为两套共驱动轴的正置式曲柄摇杆机构，但两曲柄具有一相位差。在分析驱动机构工作原理的基础上，给出了其综合问题的准确表述，即：已知机架长度和摇杆摆角，按许用传动角综合正置式曲柄摇杆机构。推导出这类机构最小传动角与杆长及摇杆摆角之间的解析关系，分析最小传动角接近其上确界时的杆长及最大杆长比变化趋势，进而建立了按许用传动角综合正置式曲柄摇杆机构的解析法。给出了翻板机驱动机构综合实例，性能参数分析结果验证了综合方法的正确性和可行性。

Abstract

The driving linkage of single-crank and bi-rocker in plate turnover machine is essentially two crank-rocker linkages of centric type together with a driving shaft，in which two cranks have a phase difference. The working principle of the driving mechanism is analyzed and its accurate description of synthesis problem，which is synthesizing a crank-rocker mechanism of centric type according to allowable transmission angle，when the frame length and the swinging angle of rocker are given. The analytic relation of these mechanisms between the minimum transmission angle and the link lengths，the swinging angle of rocker is derived，the changing trends of the link lengths and the maximum length ratio when minimum transmission angle approaches its supremum is also analyzed. Furthermore，the analytic method is built to synthesize a crank-rocker mechanism of centric type according to permissible transmission angle. A case for synthesizing the driving linkage in plate turnover machine is given，and then the correctness and feasibility of the synthesis method of the results of performance parameter analysis are verified.
