标准解读
《GB/T 25763-2024 滚动轴承 汽车变速箱用滚针轴承》与《GB/T 25763-2010 滚动轴承 汽车变速箱用滚针轴承》相比，主要在以下几个方面进行了更新和调整：
首先，在标准的适用范围上有所扩展。新版本不仅涵盖了原有型号的滚针轴承，还增加了对新型号滚针轴承的要求，以适应近年来汽车工业技术的发展需求。
其次，对于材料的要求更加严格。2024版标准中明确了更多种类的材料选项，并且提高了对材料性能的具体要求，比如硬度、耐腐蚀性等指标都有所提升，旨在提高产品的使用寿命和可靠性。
再者，关于制造精度的规定也更为详细。新版标准细化了尺寸公差、形位公差等方面的要求，确保了产品的一致性和互换性，有利于提高整个行业的标准化水平。
此外，检测方法和技术条件也有相应更新。为了更好地保证产品质量，《GB/T 25763-2024》引入了一些先进的测试手段和技术规范，如改进后的疲劳寿命试验方法等，这有助于更准确地评估轴承的实际工作性能。
最后，在包装、标志以及运输储存条件等方面也做了适当修改和完善，增强了指导性和操作性，便于企业实施及执行。
