一、对改进采煤机无链牵引系统的几点看法 在综采配套设备中批量生产的无链牵引系统的使用量增多和应用范围的扩大均要求进一步对这种系统进行完善工作。驱动功率的增加,通常机械的重量亦要增加,因而对牵引系统和牵引力的要求也高。 采煤机无链牵引系统主要部件是移动器,它在很大程度上决定着系统的可靠性、寿命和输出特性。所以其类型的选择是一件极为重要的事情。苏联在六十年代末研制无链牵引系统时采用了轮型移动器,这种移动
I. Some Opinions on Improving the Chainless Traction System of Shearers The increasing use of chainless traction systems mass-produced in the fully mechanized supporting equipment and the expanding application range all require further improvement of such systems. Drive power increases, usually the mechanical weight also increased, so the traction system and traction requirements are high. The main part of the chainless traction system of the shearer is the mover, which largely determines the reliability, life and output characteristics of the system. So the type of choice is a very important thing. The Soviet Union used a wheel-type mover to develop a chainless traction system in the late 1960s. This movement
