It's very important for some petroleum machinery(e. g. drilling rig and pumping unit) to carry on reliability analysis and design of the system of the narrow V type beltdrive.
开展窄V带传动系统可靠性分析与设计对于提高钻机、抽油机等石油钻采机械的质量和效益具有重要意义。

Reliability design of V-beltdrive get not only a small size? Light wight but also high reliability in the circulating pump.
讨论了泵中V带传动的可靠性设计与传统设计比较，不仅根数少、尺寸小、质量轻，而且可靠性高。

The Vbelt wheels of noise experimental table of main carriage reduction gear must suit drive ratio, be lightest in weight and least in moment of inertia .
