链条功率选用 SELECTION OF CHAIN DRIVE POWER DONGHUA PRODUCT CATALOGUE 2011 传递功率时，应对主动链轮所传递的功率(即输入功率)进行修正。 实际传递功率(修正功率)＝输入功率×工况系数×齿数系数 1.08 工况系数见下表所列， 齿数系数＝（19/Zs） （Zs—小链轮齿数) The standard of Guidelines for the Selection of Roller Chain Drives(GB/T 18150-2006 / ISO 10823:2004) had been issued. If you try to calculate the actual transmission power of chain, you must consider revising the transmission power of driving sprocket (input power). Actual power(Corrected power)=input power×service factor× teeth factor Service factor is listed in the following table. Teeth factor = (19/Zs)1.08 (Zs—tooth number of the small sprocket) ■ 工况系数表 Service factor table 主动机械特性 Driving Mechanism Characteristic 从动机械特性 Driven Mechanism Characteristic 平稳运转 Smooth Running 1.0 1.1 1.3 中等振动 Medium Vbration 1.4 1.5 1.7 严重振动 Severe Vbration 1.8 1.9 2.1 世界各 10823:2004标准也建立了特定条件下的功率曲线图，选择链条传动功率或由传动功率选择链条，前提是已知 小链轮齿数和转速，链条实际传递的功率在功率曲线图的额定功率范围内，所选择的链条才是合适的。 现以工农十二型手扶拖拉机传动部分和旋耕部分的传递功率，验算链条选择是否合理。 The chain factories with long history in the world have their own chain transmission power rating graph and power diagram. We can refer to the GB/T 18150-2006 / ISO 10823:2004 standard selecting the drive power or selecting chain according to the drive power, the condition is that we should know the tooth number of the small sprocket and its speed. Only if the actual power is within the range of rating power of the power rating graph, the selected chain is suitable. Now we use the transmission part in walking tractor and the transmission power in rotary tillage to proof whether the ch
