This document specifies the fundamental formulae for use in tooth bending stress calculations for involute external or internal spur and helical gears with a rim thickness sR > 0,5 ht for external gears and sR > 1,75 mn for internal gears. In service, internal gears can experience failure modes other than tooth bending fatigue, i.e. fractures starting at the root diameter and progressing radially outward. This document does not provide adequate safety against failure modes other than tooth bending fatigue. All load influences on the tooth root stress are included in so far as they are the result of loads transmitted by the gears and in so far as they can be evaluated quantitatively. This document includes procedures based on testing and theoretical studies such as those of Hirt[11], Strasser[14] and Brossmann[10]. The results are in good agreement with other methods (References [5], [6], [7] and [12]). The given formulae are valid for spur and helical gears with tooth profiles in accordance with the basic rack standardized in ISO 53. They can also be used for teeth conjugate to other basic racks if the virtual contact ratio εαn is less than 2,5. The load capacity determined on the basis of permissible bending stress is termed “tooth bending strength”. The results are in good agreement with other methods for the range, as indicated in the scope of ISO 6336-1. If this scope does not apply, refer to ISO 6336-1:2019, Clause 4.
喷丸清理以去除工件表面油污、氧化皮、锈蚀和机械加工毛刺为目的。齿轮表面的喷丸强化主要是借助于高速运动的弹丸冲击零件的表面,使其发生弹性塑性变形,从而产生残余压应力、加工硬化和组织细化等有利的变化,以提高齿轮的弯曲疲劳强度和接触疲劳强度,是改善齿轮抗咬合能力、提高齿轮使用寿命的重要途径。齿轮的齿根部分是最重要的部位,齿面上有较深的压缩层,可以减少齿轮的点蚀,延长齿轮的使用寿命。...
:在陆地或空中移动的任何类型的车辆都需要进行应力测量或微结构控制。所以运输行业显然是我们的主要应用领域。如果被要求命名典型的机械工程产品,我会先计算齿轮和滚珠或滚子轴承数。这些部件受到极大的应力,必须承载重载荷,用特定的冶金来制造一定的微观结构,而且需要进行质量控制。我们所处理的部件昂贵且至关重要,例如高强度材料,如凸轮轴、曲轴、轴承、齿轮、起落架等。...
试验机部分功能: 1、自动清零:计算机接到试验开始指令,测量系统便自动清零 2、自动返车:自动识别试验断裂后,活动横梁自动高速返回初始位置 3、自动存盘:试验数据和实验条件自动存盘,杜绝因突然断电忘记存盘引起的数据丢失 4、测试过程:试验过程及测量、显示、分析等均由微机完成 5、显示方式:数据和曲线随试验过程动态显示 6、结果再现:试验结果可任意存取,...
点击蓝字关注我们Part.1汽车零部件强度/刚度测试强度是指零部件件承受载荷后抵抗发生断裂或超过容许限度的残余变形的能力。也就是说,强度是衡量零部件本身承载能力(即抵抗失效能力)的重要指标。刚度是指在施加不至于毁坏零部件的普通外力时,零部件不容易变形的能力,也就是指恢复原形的弹性变形能力。...
