技术领域
本发明属于滚子轴承技术领域，具体涉及一种耐磨损的圆锥滚子轴承。
背景技术
圆锥滚子轴承属于分离型轴承，轴承的内、外圈均具有锥形滚道。该类轴承按所装滚子的列数分为单列、双列和四列圆锥滚子轴承等不同的结构型式。单列圆锥滚子轴承可以承受径向负荷和单一方向轴向负荷。当轴承承受径向负荷时，将会产生一个轴向分力，所以当需要另一个可承受反方向轴向力的轴承来加以平衡。
现有的圆锥滚子轴承在日常使用中，需要进行润滑来延长使用寿命，现有的润滑方式操作繁琐，存在简化润滑的可能，同时现有轴承的内圈与滚子的限位安装中，紧固度不够，以及后期运行中的径向荷载较大时，滚子与保持架大面积接触，影响滚子的传动效率，以及现有圆锥滚子轴承的耐磨损性能较差，因此存在可改进的空间。
发明内容
本发明的目的在于提供一种耐磨损的圆锥滚子轴承，以解决上述背景技术中提出的圆锥滚子轴承在润滑方式、限位安装中操作较为不便，以及在负荷较大时，会影响正常滚子传动效率的问题。
为实现上述目的，本发明提供如下技术方案：一种耐磨损的圆锥滚子轴承，包括内圈、保持架、外圈以及滚子，所述保持架的表面等角度开设有面槽，所述滚子嵌入在面槽的内侧，所述内圈处于保持架的内部，用于对滚子压紧，且内圈的外侧面与滚子贴合，所述外圈套设在保持架的外部，且滚子与外圈的内壁滚动贴合，所述保持架的顶端面内壁开设有环槽，在所述环槽的内部放置有环盖，所述环槽的底端面开设有竖直状的注油孔，用于注入润滑油进行润滑，所述注油孔的数量与面槽的数量相适配，且每个注油孔均处于单个面槽的一侧，所述注油孔的侧边与面槽的一侧内壁之间贯通开设有导向孔，实现润滑。
优选的，所述面槽的内部底端面上开设有球孔，所述球孔的内部嵌入有滚珠，用于对滚子进行支撑，所述球孔的内部还设置有橡胶垫，所述橡胶垫与滚珠贴合连接，所述滚珠与滚子的端面滚动贴合。
优选的，所述内圈的外壁顶部形成有贴合面，所述贴合面与滚子的顶端面贴合，所述内圈的外壁中部形成有导向面，用于插入时的导向，插入完成后，能够通过贴合面实现限位卡止，所述导向面的底端与滚子的侧边接触。
优选的，所述贴合面的倾斜角度为∠b，而导向面的倾斜角度为∠a，其中∠a的倾斜角度大于∠b。
优选的，所述外圈由氮化钛涂层、高碳铬轴承钢、钼金属层构成，具有耐磨损的特性，其中高碳铬轴承钢与钼金属层分别设置在氮化钛涂层的内外壁处。
优选的，所述内圈、保持架、外圈以及滚子的材质相同，整体耐磨损性能高。
优选的，所述内圈、保持架、外圈以及滚子的倾斜度相等，所述滚子的纵截面呈等腰梯形结构。
与现有技术相比，本发明的有益效果是：
1.通过设计的注油孔、导向孔，以及环槽，能够方便的实现对滚子的润滑，相比较现有人工涂抹的方式，本结构的设置，不仅能够提高工作效率，又能够使得润滑更加均匀；
2.通过设计的贴合面和导向面，能够在使用中，快速实现紧密贴合，保证安装稳固性；
3.通过设计的滚珠和橡胶垫，能够在运行中，当径向荷载较大时，对滚子进行支撑，避免滚子与保持架接触而影响传动；
4.通过设计的氮化钛涂层，能够提升外圈的耐磨损能力，延长外圈以及整个轴承的使用寿命。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1至图6，本发明提供一种技术方案：一种耐磨损的圆锥滚子轴承，包括内圈1、保持架2、外圈3以及滚子4，保持架2的表面等角度开设有面槽9，滚子4嵌入在面槽9的内侧，内圈1处于保持架2的内部，且内圈1的外侧面与滚子4贴合，外圈3套设在保持架2的外部，且滚子4与外圈3的内壁滚动贴合，保持架2的顶端面内壁开设有环槽10，在环槽10的内部放置有环盖7，环槽10的底端面开设有竖直状的注油孔11，通过设计的注油孔11、导向孔8，以及环槽10，能够方便的实现对滚子4的润滑，相比较现有人工涂抹的方式，本结构的设置，不仅能够提高工作效率，又能够使得润滑更加均匀，注油孔11的数量与面槽9的数量相适配，且每个注油孔11均处于单个面槽9的一侧，注油孔11的侧边与面槽9的一侧内壁之间贯通开设有导向孔8，面槽9的内部底端面上开设有球孔13，球孔13的内部嵌入有滚珠12，球孔13的内部还设置有橡胶垫14，通过设计的滚珠12和橡胶垫14，能够在运行中，当径向荷载较大时，对滚子4进行支撑，避免滚子4与保持架2接触而影响传动，橡胶垫14与滚珠12贴合连接，滚珠12与滚子4的端面滚动贴合。
本实施例中，优选的，内圈1的外壁顶部形成有贴合面5，贴合面5与滚子4的顶端面贴合，内圈1的外壁中部形成有导向面6，通过设计的贴合面5和导向面6，能够在使用中，快速实现紧密贴合，保证安装稳固性，导向面6的底端与滚子4的侧边接触，贴合面5的倾斜角度为∠b，而导向面6的倾斜角度为∠a，其中∠a的倾斜角度大于∠b。
本实施例中，优选的，外圈3由氮化钛涂层15、高碳铬轴承钢16、钼金属层17构成，通过设计的氮化钛涂层15，能够提升外圈3的耐磨损能力，延长外圈3以及整个轴承的使用寿命，其中高碳铬轴承钢16与钼金属层17分别设置在氮化钛涂层15的内外壁处，内圈1、保持架2、外圈3以及滚子4的材质相同，内圈1、保持架2、外圈3以及滚子4的倾斜度相等，滚子4的纵截面呈等腰梯形结构。
本发明的工作原理及使用流程：本发明在安装中，先将滚子4放置在保持架2内，并使得滚子4的一部分处于面槽9的内侧，随后再将内圈1从保持架2的内部卡入，通过外部压合设备将内圈1朝向保持架2的底部压合，在压合中，导向面6底端内侧会先一步与滚子4的侧边接触，在持续压合中，贴合面5会与滚子4的顶部侧边贴合，此时滚子4被挤压至面槽9的内部，再将环盖7放置在环槽10的内部后，通过螺栓将环盖7与环槽10固定，最后再将上述组成好的成品放置在外圈3的内部即可；在需要润滑时，将环盖7分离，再将润滑油倒入至环槽10的内部，此时润滑油通过注油孔11流入至导向孔8内，并从导向孔8流入至滚子4的表面，在后期滚子4的旋转中，实现均匀涂抹，在传动中，当滚子4受到较大的径向荷载时，会在面槽9的内侧移动，并挤压滚珠12，滚珠12挤压橡胶垫14实现高度调节以及对滚子4的支撑，且滚珠12可以转动，能够保证传动不受影响，在使用中，可以通过氮化钛涂层15提升轴承的耐磨损能力，而通过钼金属层17提升整体强度。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
