辊压机用行星减速器行星架的修复

Repairment of Planetary Carrier of Roller Press Planetary Reducer

辊压机用行星减速器在拆卸过程中容易造成行星架输出空心轴部位的损坏。针对该损坏的行星架,提出一种双臂式的修复方案,并利用SolidWorks软件对其进行三维建模,使用其中的Simulation模块对其应力和位移进行分析。结果表明,修复后的行星架最大应力为306.7 MPa,行星轮销轴孔处相对位移为0.09 mm,满足行星架强度和刚度要求,即满足使用要求。

The disassembly of the planetary carrier of a roller press planetary reducer is easy to cause damage to the hollow output shaft. Aiming at the repair of the damaged planetary carrier, a biiateral board planetary carrier is brought up. The repair scheme is proposed, the 3 D modeling of the damaged planetary carrier is carried out by using SolidWorks and using the simulation part of the software, the stress and displacement of the carrier are analyzed. The results show that, the maximum stress of the repaired planetary carrier is 306.7 MPa, the relative displacement of the pin hole of planet wheel is 0.09 mm. This result is able to satisfy the request of the strength and stiffness of planetary carrier. On conclusion, this repair scheme can meet the use requirement in practice.
