煤机轴承的选用注意事项，以及尺寸，型号，轴承厂家的选择

煤机主要应用与井下开采 相比露天采掘，地下采煤的难度更大，环境也更恶劣，一旦因设备故障而停机，由于空间狭小、不方便使用大尺寸的拆卸和维护工具，维修将会非常费时，费力，这将对煤炭产量带来负面影响，是煤矿业主所不希望看到的。因此，煤机的性能与可靠性对于地下采煤作业的连续性以及采煤量的多少起着决定性作用。

无锡爱思米轴承可以生产各种系列煤机轴承，无锡爱思米轴承具有良好的抗冲击载荷能力，具有良好的润滑性能，具有更高的使用寿命。

煤机选择的注意事项：

煤机用滚动轴承的种类，类型及尺寸是多种多样的，为使机械装置发挥出预期的性能，选择最适宜的轴承是至关重要的。为选定轴承，需要分析诸多要素，从各个角度进行研究，评价，有关选择轴承的程序，并无特殊规定，但一般顺序如下：

机械装置和轴承的使用条件等

明确对轴承的要求

选定轴承的类型

选定轴承配置方式

选定轴承尺寸

选定轴承规格

选定轴承的安装方法

煤机轴承的尺寸及选择方法：

轴承在承受载荷旋转时，由于套圈滚道面及滚动体滚动面不断地受到交变载荷的作用，即使使用条件正常，也会因材料疲劳使滚道面及滚动面出现鱼鳞状损伤（称做剥离或剥落）。出现这种滚动疲劳损伤之前的总旋转数称做轴承的“（疲劳）”寿命。即使是结构、尺寸、材料、加工方法等完全相同的轴承，在同样条件下旋转时，轴承的（疲劳）寿命仍会出现较大的差异。这是因为材料疲劳本身即具有离散性，应从统计的角度来考虑。于是就将一批相同的轴承在在同样条件下分别旋转时，其中90%的轴承不出现滚动疲劳的损伤的总旋转数称做“轴承的基本额定寿命”（可靠性为90%的寿命）。在以固定的转速旋转时也可用总旋转时间表示。但在实际工作时，还会出现滚动疲劳损伤以外的损伤现象。这些损伤可以通过做好轴承的选择、安装和润滑等加以避免。
