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.

Key words: Key words：Scraper conveyor, the power imbalance, the allocation of motor power, sequence starting
