摘　　要：介绍了一种适用于变频驱动刮板输送机的新型紧链装置设计。为解决目前刮板输送机的紧链装置存在的问题及实际需要,根据变频电动机的低频低速恒转矩运转的特点,重新设计刮板输送机用的低频直驱紧链系统。对制动转矩、离合及控制进行了分析研究。试验证明,新型紧链系统具有运行安全、操作方便、性能可靠、结构紧凑、工作高效等特点。The design of a new type of tight chain device suitable for variable frequency drive scraper conveyor is introduced. In order to solve the problems and practical needs of the current tight chain device of the scraper conveyor,this paper redesigns the low frequency direct drive tight chain system for the scraper conveyor according to the characteristics of low frequency and low speed constant torque operation of the variable frequency motor. The braking torque, clutch and control are analyzed and studied. The test proves that the new tight chain system has the characteristics of safe operation, convenient operation, reliable performance, compact structure and high efficiency.
