摘要 word文档整理分享 PAGE IV 参考资料 十字交叉滚轮轴承的设计 摘 要 轴承是当代机械设备中的一种重要零部件，主要是用来支撑旋转体或其他运动体，引导或移动运动并承受由轴或轴上零件传递而来的载荷。随着技术的革新和轴承的发展，轴承种类也越来越多。其中的滚轮轴承主要应用低速、重载、受一定冲击的场合，应用相当广泛，但是在一些需要双向定位和滚动导向的场合，如电梯、升降机、重型机床和绕固定轨道行走的机械中就需要一种特殊的轴承——十字交叉滚轮轴承。十字交叉滚轮轴承不仅结构简单，因为该轴承的大、小滚轮外径的素线相互垂直，所以可以进行双向定位和滚动导向，稳定性和可靠性很高，也可减少磨损和驱动功率。此次设计就是进行十字交叉滚轮轴承的学习，首先根据设计要求进行各组成部分的设计，再进行负载和寿命的计算，最后再编制加工工艺，系统的学习十字交叉滚轮轴承的知识。深入研究十字交叉滚轮轴承。 关键词：机械设备，双向定位，滚动导向，十字交叉滚轮轴承 Cross roller bearing design ABSTRACT Bearing?is?an?important?part?of?contemporary?mechanical?equipment,which?is?mainly?used?to?support?the?revolver?or?other?sports.It?can?guide?or?move?sports?and?bear?the?load?transferred?by?axial?shaft?parts.With?the?innovation?of?technology?and?the?development?bearing,there?are?more?and?more?bearing?types.Roller?bearings?are?extensively?applied?in?low?speed,overloading?and?shocked?occasions.But?in?some?occasions?that?two-way?position?and?rolling?guide,such?as?elevator,heavy?me?chine?and?fixed?orbit?round?to?walk?machine?need?a?special?bearing,that?is?cross?wheel?bearing.The?structure?of?roller?cross?bearing?is?simple,because?the?large?and?small?roller?bearings?outer?grain?line?is?vertical,it?can?not?only?undertake?two-way?position?and?rolling?guide,stability?and?high?veil?ability,but?also?reduce?wear?and?driving?power.The?objective?of?this?design?is?to?proceed?the?study?of?the?cross?wheel?bearing,meet?the?requirement?is?the?first?part?of?this?design,and?then?the?calculation?of?load?and?life?finally?to?prepare?the?learning?process?system?of?cross?roller?bearing.These?contribute?to?deep?study?of?cross?roller?bearing.
