窄V带传动适用于载荷波动较大、工况较恶劣的场合,在石油钻采机械中有取代三角胶带的趋势。本文介绍了窄V带的计算公式、设计方法,并给出了程序使用说明、程序框图、程序清单及应用实例。应用本程序可减轻程序设计人员的重复性脑力劳动,提高设计计算效率。 Narrow V-belt drive for large load fluctuations, the conditions of the more harsh conditions, in the oil drilling machinery to replace triangular tape trends. This article describes the narrow V-band calculation formula, design methods, and gives the program instructions, block diagrams, program list and application examples. The application of this procedure can reduce the repetitive mental workload of programmers and improve the design calculation efficiency.
