This part of ISO 6336 presents the basic principles of, an introduction to, and the general influence factors for, the calculation of the load capacity of spur and helical gears. Together with ISO 6336-2, ISO 6336-3, ISO 6336-5 and ISO 6336-6, it provides a method by which different gear designs can be compared. It is not intended to assure the performance of assembled drive gear systems. It is not intended for use by the general engineering public. Instead, it is intended for use by the experienced gear designer who is capable of selecting reasonable values for the factors in these formulae based on knowledge of similar designs and awareness of the effects of the items discussed. The formulae in ISO 6336 are intended to establish a uniformly acceptable method for calculating the pitting resistance and bending strength capacity of cylindrical gears with straight or helical involute teeth. ISO 6336 includes procedures based on testing and theoretical studies such as those of Hirt [1], Strasser [2] and Brossmann [3]. The results of rating calculations made by following this method are in good agreement with previously accepted gear calculations methods (see References [4] to [8]) for normal working pressure angles up to 25° and reference helix angles up to 25°). For larger pressure angles and larger helix angles, the trends of products YF YS Y β and, respectively, ZH Z ε Z β are not the same as those of some earlier methods. The user of ISO 6336 is cautioned that when the methods in ISO 6336 are used for other helix angles and pressure angles, the calculated results will need to be confirmed by experience. The formulae in ISO 6336 are not applicable when any of the following conditions exist: ⎯ spur or helical gears with transverse contact ratios less than 1,0; ⎯ spur or helical gears with transverse contact ratios greater than 2,5; ⎯ interference between tooth tips and root fillets; ⎯ teeth are pointed; ⎯ backlash is zero. The rating formulae in ISO 6336 are not applicable to other types of gear tooth deterioration such as plastic yielding, scuffing, case crushing, welding and wear, and are not applicable under vibratory conditions where there may be an unpredictable profile breakdown. The bending strength formulae are applicable to fractures at the tooth fillet, but are not applicable to fractures on the tooth working surfaces, failure of the gear rim, or failures of the gear blank through web and hub. ISO 6336 does not apply to teeth finished by forging or sintering. It is not applicable to gears which have a poor contact pattern. The procedures in ISO 6336 provide rating formulae for the calculation of load capacity, based on pitting and tooth root breakage. At pitch line velocities below 1 m/s the gear load capacity is often limited by abrasive wear (see other literature for information on the calculation for this).
蜗轮蜗杆减速器在运行过程中,不仅会承受齿轮啮合和轴承运行过程中带来的振动,还会受到轴系不平衡度和外界因素的影响,一旦产生振动,会导致整个机器振动,严重时甚至直接导致零部件的破坏失效,从而导致整个机器不能运行。一般情况下,我们可以根据载荷形式来区分振动,确定载荷可以进行瞬态、谐响应、响应谱等分析。不确定载荷可以进行随机振动分析。...
这样即能利用减速机生产厂商的成熟技术,也能在更短的生产周期内满足用户需要,这对缩短设计及生产周期特别有效果。 随着技术的发展和计算机的应用,对齿轮齿形的计算越来越精确,世界传动技术的发展趋于采用硬齿面。据统计,由于硬齿面减速机的采用大大地促进了机器的重量轻、小型化和质量性能的提高,使机器的工作速度提高一个等级。...
由于影响磨矿机生产能力的因素较多,而且变化大,还没有精确计算磨矿机生产能力的理论公式。所以磨矿机的生产能力一般是根据经验公式,采用近似方法进行计算。常用的计算方法有以下两种:磨矿机按给矿计的单位生产能力计算法(也称容积计算法)和磨矿功率计算法。我国常用的是容积计算法,这种方法计算比较方便。不管是球磨机还是生铁渣棒磨机,只要选择适合自己的就好。...
