为提高采煤机牵引系统的可靠性,确保工作面的工作安全,近年来迅速发展了无链牵引系统。许多国家,特别是英、西德等国,对无链牵引系统的结构进行了大量的试验研究工作。近期,我国的采煤机制造和科研人员也对无链牵引系统给予了足够的重视。不久,我国产的无链牵引采煤机也会问世。为促进我国无链牵引采煤机的研制,下面介绍一种无链牵引系统的型式试验装置,试验方法及
In order to improve the reliability of the shearer traction system and ensure the working safety of the working face, the chainless traction system has been rapidly developed in recent years. Many countries, especially Britain, West Germany and other countries, carried out a great deal of experimental research on the structure of a chainless traction system. Recently, China’s coal winning machine manufacturing and scientific research personnel also paid enough attention to the chainless traction system. Soon, my country’s chain-free haulage shearer will also come out. In order to promote the development of chainless haulage shearer in China, the following introduces a type chainless traction system type test device, test method and
