Abstract

本发明公开了一种耐磨圆锥滚子轴承，包括轴承内圈、轴承外圈、滚动体及保持架，保持架上设有兜孔，圆锥滚子装配在兜孔内，所述保持架设置在轴承内圈和轴承外圈之间，轴承内圈、外圈及滚动体均采用硬度高的轴承钢GCr15，所述轴承内圈滚道经超精磨削加工后产生微米级的凸度。传统圆锥滚子轴承在使用过程中会在滚动体与轴承内圈挡边两侧产生塑性变形，继而产生噪音、振动及疲劳剥落。本发明对圆锥滚子轴承内圈进行结构优化，使滚子与轴承内圈之间由线接触变为点接触，使轴承静态时的着力点为凸面顶点，在高速负荷运转时，使轴承达到受力均匀，有效降低轴承摩擦力矩，增大了轴承滚珠与滚道间的耐磨性，减弱了轴承噪音，提高了轴承的使用寿命。

Description

一种耐磨圆锥滚子轴承
技术领域
本发明涉及轴承技术领域，具体涉及一种耐磨圆锥滚子轴承。
背景技术
轴承是机械行业中的重要部件，轴承的精度直接影响到设备的工作状况，进而直接影响到设备的质量与寿命。滚动轴承在各行各业的应用日益广泛，轴承的需求量也越来越大。随着滚动轴承应用领域的不断扩展和技术的不断进步，滚动轴承的结构也越来越复杂。圆锥滚子轴承，滚动体是圆锥滚子的向心滚动轴承。现有圆锥滚子轴承为了将圆锥滚子限制在滚道内，总有用于轴向固定圆锥滚子的挡边，通常挡边在内圈。由于圆锥滚子与挡边为磨损较滚动摩擦大得多的滑动摩擦，且在承受载荷的情况下极易使滚动体与轴承内圈挡边两侧产生塑性变形，继而产生噪音、振动及疲劳剥落。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种内圈经超精磨削加工后存在凸度的新型圆锥滚子轴承，改变圆锥滚子轴承的传统接触方式，由线接触变为点接触，使滚子减少与轴承内圈内侧之间的接触受力。极大延长了轴承的使用寿命，减少了噪音及振动。
为实现上述目的，本发明提供了如下技术方案：一种圆锥滚子轴承，包括有轴承外圈、轴承内圈、圆锥滚子以及保持架，保持架上设有兜孔，圆锥滚子装配在兜孔内，所述保持架设置在轴承内圈和轴承外圈之间，其特征在于：传统圆锥滚子轴承在使用过程中会在滚动体与轴承内圈挡边两侧产生塑性变形，继而产生噪音、振动及疲劳剥落。轴承内圈滚道经结构优化后产生微米级的凸度，使滚动体与轴承内圈的线接触变为点接触，增大了轴承滚珠与滚道间的耐磨性，减弱了轴承噪音，提高了轴承的使用寿命。同时，轴承内圈开有凹槽，润滑介质自凹槽内流过，增强了润滑效果，防止轴承受交变应力后产生的金属颗粒对轴承滚道的磨损。
进一步地，所述圆锥滚子轴承内圈滚道表面突起为环形突起。
进一步地，所述圆锥滚子轴承内圈滚道凸度为4um。
进一步地，所述圆锥滚子轴承内圈凹槽为环形。
本发明的有益效果如下：
1.本发明通过对圆锥滚子轴承进行结构优化，改变轴承滚子与滚道之间的传统接触方式，减少了滚子与滚道侧面之间的接触压力，提高了轴承的使用寿命；
2.本发明有效的防止了轴承内圈侧面的疲劳剥落，减少了磨屑，提高了轴承的耐磨性，减弱了轴承噪音及振动；
3.本发明通过对轴承内圈开设环形凹槽，增强了润滑效果，同时减少了轴承磨损。
附图说明
下面结合附图和实施例对本发明作进一步说明：
图1是圆锥滚子轴承整体示意图；
图2是圆锥滚子轴承剖视图；
图3是圆锥滚子轴承A点局部放大图；

图5是圆锥滚子轴承改良后有限元分析结果
图中，1、轴承内圈，2、轴承外圈，3、保持架，4、滚动体，5、接触间隙，6、凹槽。
具体实施方式
为了使本发明的内容更容易被清楚地理解，下面根据具体实施例并结合附图，对本发明作进一步详细的说明。
如图1、图2、图3所述的耐磨圆锥滚子轴承，包括轴承内圈1、轴承外圈2、滚动体4及保持架3，保持架3上设有兜孔，圆锥滚子4装配在兜孔内，所述保持架设置在轴承内圈1和轴承外圈2之间，轴承内圈1、外圈2及滚动体4采用硬度高的轴承钢GCr15，保持架3采用聚四氟乙烯，轴承内圈1上开设有凹槽6，所述轴承内圈滚道经超精磨削加工后产生微米级的凸度5。
如图4、图5所示，对标准轴承与优化后轴承分别进行有限元分析，根据实际运行工况，对其外圈进行固定约束，对内圈施加转速及额定载荷，分析发现，未经优化的轴承滚珠与内圈接触变形为3.9um、3.6um、3.56um、3.50um，经优化后轴承的接触变形仿真结果分别为0.53um、0.26um、0.29um、0.62um；从有限元分析结果中可以看出，经优化后的轴承接触变形上要明显小于标准轴承。
具体地，所述圆锥滚子轴承内圈滚道表面突起为环形突起。
具体地，所述圆锥滚子轴承内圈滚道凸度为4um。
具体地，所述圆锥滚子轴承内圈凹槽为环形。
相比于标准圆锥滚子轴承在使用过程中会在滚动体与轴承内圈挡边两侧产生塑性变形，继而产生噪音、振动及疲劳剥落。本发明使轴承内圈滚道经磨削加工后产生微米级的凸度，使滚动体与轴承内圈之间的线接触变为点接触，减少了轴承滚子与内圈两侧间的接触受力，增大了轴承滚珠与滚道间的耐磨性，减弱了轴承噪音，提高了轴承的使用寿命。同时，轴承内圈开有凹槽，润滑介质自凹槽内流过，增强了润滑效果，防止轴承受交变应力后产生的金属颗粒对轴承滚道的磨损。
以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
