speed of crankshaft

Water pump and cooling fan of traditional cars are usually driven by the engine through V belt, which is intertwined between crankshaft pulley and water pump pulley. Therefore, the rotational speed of water pump is in proportional relationship with the engine speed.

而传统汽车的水泵和散热风扇一般由发动机曲轴通过V带传动，传动带环绕在曲轴带轮与水泵带轮之间，因此水泵转速与发动机转速成比例关系。

The output for diesel engine is proportional to the product of crankshaft rotation speed and injection pump rack displacement from fuel supply starting point. Injection pump rack displacement influences diesel engine rotation stability and locomotive tractive characteristic.

柴油机输出功率的大小跟曲轴转速与喷油泵齿条由供油始点开始的位移量乘积成正比，喷油泵齿条位移量影响柴油机运转的稳定性和机车的牵引特性。

The conclusion from the analysis points out that the effective way to raise the productivity of this series of looms, while maintaining the same shuttle speed and low power consumption, is to increase the angle of crankshaft rotation available for the passage of the shuttle.

文章从分析得出结论：从既提高生产率，又维持棱速不变，并保持较低的功率消耗来看，唯一有效的措施是进一步扩大梭子越过梭道的时间角度。

The primary drive gear ( crankshaft gear) and the primary driven gear are the source of noise due to their high speed and bigger reduction ratio.

作为摩托车初级传动的曲轴齿轮及初级从动齿轮，由于转速高及降速比大，是产生噪声的主要因素。
