刮板输送机是当今采、掘生产过程中的关键设备之一。输送机工作状态的好坏,对工作面以至全矿井主要技术经济指标有着决定性的影响。虽然近十多年来,我国在输送机的品种上有了不少创新和发展,但是其驱动传动系统仍然沿用着传统的方法,即由单速电机→液力偶合器→减速器→输送机刮板链传动滚筒。经过20多年的实践证明这种传动系统起到了预期的作用,但也确实带来不少副作用,其中最为突出且有普遍性的问题是:驱动电机与液力偶合器传动联合工作的合理匹配。在现场运行中,由于客观条件的变化,尤其是当液力偶合器喷油后的重新注油和调
Scraper conveyor is one of the key equipment in mining and digging production. Conveyor working status is good or bad, the main technical and economic indicators of the face and the whole mine has a decisive impact. Although there have been a lot of innovations and developments in the past few decades in our country, our drive transmission system still follows the traditional method, that is, from single speed motor → hydraulic coupling → retarder → conveyor Scraper chain drive roller. After more than 20 years of practice, this drive system has been proved to have the desired effect, but it does bring a lot of side effects. The most prominent and common problem is the reasonable match between drive motor and hydraulic coupling drive. In the field of operation, due to changes in the objective conditions, especially when the hydraulic coupling refueling and fuel injection
