台架试验是研制新产品的重要阶段,也是机器出厂前检验产品质量的重要手段。试验时要弄清并消除所有结构上的缺陷和工艺上的误差,测定工作特性,确定各个部件及整个传动装置的寿命和可靠性。我国采煤机械化水平在迅速提高,采煤机的种类和数量日益增多。为了保证采煤机在出厂前达到质量要求,在煤矿修配厂大修后恢复其原有的技术指标,必须通过试验台试验,这是不可缺少的一环。为此,辽源煤矿机械厂设计了MLTS—3000型(图1)和MLTS—6000型(图2)风动摩擦加载试验
Bench test is an important stage in the development of new products, but also an important means of testing the product quality before delivery. Test to identify and eliminate all structural defects and process errors, determine the characteristics of the work to determine the life of all components and the entire transmission and reliability. The level of coal mechanization in our country is rapidly increasing, and the type and number of shearer are increasing day by day. In order to ensure that the shearer reaches the quality requirements before it leaves the factory, it is an indispensable part to pass the test bench test after restoring its original technical specifications after overhaul of the coal dressing plant. To this end, Liaoyuan Coal Mine Machinery Factory designed the MLTS-3000 (Figure 1) and MLTS-6000 (Figure 2) wind dynamic friction loading test
