机床行业对轴承的需求

滚动轴承在机床上的使用主要用于下列三个部位：主轴、滚珠丝杠和一般传动轴。

主轴轴承作为机床的基础配套件，其性能直接影响到机床的转速、回转精度、刚性、抗颤振动切削性能、噪声、温升及热变形等，进而影响到加工零件的精度、表面质量等。因此，高性能的机床必须配用高性能的轴承。

滚动轴承的精度一般分为P0、P6、P5、P4和P2五个等级，用于精密机床主轴上的轴承精度应为P5及其以上级，而对于数控机床、加工中心等高速、高精密机床的主轴支承，则需选用P4及其以上级超精密轴承。

机床用主轴轴承通常包括深沟球轴承、角接触球轴承、圆柱滚子轴承、双向推力角接触球轴承、圆锥滚子轴承和推力轴承等六种结构类型。

随着数控技术的快速发展，“复合、高速、智能、精密、环保”已成为当今机床工业技术发展的主要趋势。其中，高速加工可以有效地提高机床的加工效率、缩短工件的加工周期。这就要求机床主轴及其相关部件要适应高速加工的需求。目前，数控机床主轴轴承基本上限定在角接触球轴承、圆柱滚子轴承、双向推力角接触球轴承和圆锥滚子轴承等四种结构类型。

伴随着数控机床主轴向高速化发展，陶瓷材料(主要指Si3N4工程陶瓷)因具有密度小、弹性模量高、热膨胀系数小、耐磨、耐高温、耐腐蚀等优良性能，从而成为制造高速精密轴承的理想材料。陶瓷轴承得到越来越广泛的应用，鉴于陶瓷材料的难加工性，精密陶瓷轴承多为滚动体是陶瓷、内外套圈仍由铬钢制造的混合陶瓷球轴承。

滚珠丝杠副作为精密、高效、灵敏的传动元件，除了应采用高精度的丝杠、螺母和滚珠外，还应注意选用轴向刚度高、摩擦力矩小、运转精度高的轴承。滚珠丝杠支承过去常用双向推力角接触球轴承、圆锥滚子轴承、滚针和推力滚子组合轴承、深沟球轴承和推力球轴承等。目前，滚珠丝杠支承采用最多的是60°接触角的单列推力角接触球轴承，而且，精度等级也是以机床用装于一般传动轴上的滚动轴承，其要求和选用与普通机械传动轴承相同，只需满足强度和寿命要求，转速不超过所规定的轴承极限转速即可。
