薄煤层采煤机截割部行星架有限元分析

Finite Element Analysis of Planetary Carrier of Seam Shearer Cutting Department

利用有限元分析软件ABAQUS对薄煤层采煤机截割部行星齿轮机构的行星架进行了强度校核,结果表明现有的行星架设计安全系数过大,适当减小安全系数可以增大薄煤层采煤机滚筒的装煤空间。分析得到的行星架的应力、位移分布情况可以为进一步设计薄煤层采煤机截割部行星架的结构和强度提供依据。

The FEA （Finite Element Analysis） software ABAQUS was taken to carry out planet carrier strength check of planetary gear mechanism of thin seam shearer cutting department.The result shows that the design safety factor of planet carrier is too big. Appropriate reducing safety coefficient can increase coal loading space of thin seam shearer drum. The obtained stress and displacement distribution of planet carrier can provide some basis for further designing frame and strength of planet carrier of thin seam shearer cutting department.
