摘要
根据大型光电经纬仪提出的温度控制要求,研制了多路流体关节机构。介绍了机构研究背景,说明了该机构的组成及工作原理,并通过计算摩擦阻力矩验证了机构的可行性,最后通过实验验证设计的合理性。实验结果表明,当用添加青铜的聚四氟乙烯制作的密封隔环进行密封时,能做到不泄漏,造成的摩擦阻力矩仅为1.666 N.m。该机构工作可靠,实现了流体由静到连续转动的传输,结构紧凑,设计巧妙,完全可以满足大型高精度光电设备的使用要求。
According to the temperature control requirements of a large photoelectric theodolite, a compact multiway fluid joint mechanism with skillful structure is researched and designed. The mechanism research background is introduced and the composition and principle of the mechanism are presented. The feasibility of the structure is verified through calculating the friction resistance torque. Finally, the reasonability of the structural design is verified through the theoretical analysis and experimental results. The experimental results indicate that the mechanism is no leak when the sealing ring made of PTFE combined with the bronze is utilized to seal, and the friction resistance torque is only 1. 666 N · m. The mechanism runs reliably and realizes the fluid transmission from static state to the continuous rotated state, which can meet the performance requirements of large photoelectric instrumentations properly.
