标准范围

ISO/TR 14521:2010规定了圆柱蜗轮承载能力的计算公式，并涵盖了与磨损、点蚀、蜗轮偏转、断齿和温度相关的额定载荷。ISO/TR 14521:2010不包括擦伤和其他故障模式。额定载荷和设计程序适用于齿面滑动速度高达25 m/s，接触比等于或大于2.1的情况。对于磨损，齿面上的滑动速度不低于0.1 m/s。ISO/TR 14521:2010选择的尺寸、润滑剂或材料的规则和建议仅适用于50 mm及以上的中心距离。对于小于50 mm的中心距离，方法A适用。选择合适的计算方法需要知识和经验。ISO/TR 14521:2010旨在供经验丰富的齿轮设计师使用，他们能够对各种因素做出明智的判断。它不适用于缺乏必要经验的工程师。蜗轮的几何结构很复杂，因此鼓励ISO/TR 14521:2010的用户确保建立了有效的工作几何结构。

ISO/TR 14521:2010 specifies equations for calculating the load capacity of cylindrical worm gears and covers load ratings associated with wear, pitting, worm deflection, tooth breakage and temperature. Scuffing and other failure modes are not covered by ISO/TR 14521:2010.The load rating and design procedures are valid for sliding velocities over tooth surfaces of up to 25 m/s and contact ratios equal to or greater than 2,1. For wear, sliding velocities over tooth surfaces are not below 0,1 m/s.The rules and recommendations for the dimensioning, lubricants or materials selected by ISO/TR 14521:2010 only apply to centre distances of 50 mm and larger. For centre distances below 50 mm, method A applies.The choice of appropriate methods of calculation requires knowledge and experience. ISO/TR 14521:2010 is intended for use by experienced gear designers who are able to make informed judgements concerning factors. It is not intended for use by engineers who lack the necessary experience.The geometry of worm gears is complex, therefore the user of ISO/TR 14521:2010 is encouraged to make sure that a valid working geometry has been established.
