摘要：

　　摘要：刮板输送机采用机头机尾两机驱动时，在起动运行工况中常会出现功率不平衡的现象，严重影响整机运行的可靠性。在影响刮板机电机功率分配的因素上，简化物理模型能够推导出两机功率差与额定转速有关，为选择电机功率分配提供了一种依据。同时研究了顺序起动对两机功率不平衡的影响，主要从空载起动和重载起动两种工况下得出数据。结果表明，选择合适的起动时间差能够有效改善重载起动下的功率不平衡。这些研究为解决刮板输送机的功率不平衡问题提供了新的思路。

Abstract:

　　　Abstract:The scraper using both the nose and tail driving generated the power imbalance phenomenon under the starter operating conditions,which seriously affected the reliability of machine operation.For this reason, in the influence of the the scraper motor power allocation factors, simplified physical models can be derived the relationship that the power difference was related rated speed of the two motors, then it provided a basis for selecting motor power allocation.Meanwhile analyzed the relationship between sequence starting and the power imbalance, obtained the data in the no-load starting and overloading conditions.The results showed that, choosing the starting time can be effectively improved the power imbalance under heavy starting. Those studies provided new ideas to resolve the problem of the imbalance of power scraper conveyor.
