摘要
为解决重型工业齿轮箱行星架装配难度高和生产效率低的缺点,提出新型的行星架-柱销装配结构。利用有限元对行星架受力情况进行分析,探讨了行星架与柱销在不同装配间隙下应力和变形的规律。结果表明,采用新型的行星架-柱销装配结构在满足受力的情况下,间隙配合加焊接的结构在保证连接可靠性的同时,解决了加工难、生产效率低的缺点,节约了加工成本,提高了齿轮箱的可靠性。
In order to solve the problems of high assembly difficulty and low production efficiency of the planet carrier of heavy industrial gearboxes,a new assembly structure of planet carrier and pin was proposed.The finite element method is used to analyze the stress of the planet carrier,and the stress and deformation laws of the planet carrier and the pin under different assembly clearances are discussed.The results show that the new planetary carrier-pin assembly structure can meet the stress,and the gap and welded structure together can ensure the reliable connection,and at the same time,solve the problems of difficult machining and low production efficiency,save the machining cost and improve the reliability of the gear box.
