Description

一种齿轮轴套
技术领域
本发明涉及一种轴套，特别涉及一种齿轮轴套。
背景技术
轴套是机械设计中一个重要部件，轴套通常套设在齿轮转轴上对齿轮转轴起保护作用。同时，由于齿轮转轴和轴套在使用过程中处于不断地摩擦转动的状态，所以齿轮转轴和轴套之间需要得到充分的润滑，而现有的齿轮轴套一般采用单一材料制作，综合性能差，一般只能达到单一的性能要求。轴套还起着固定轴的中心定位和轴承，不让其因为转动时震动而发生移位，然而不断的摩擦，会使轴套产生较大的热量，日积月累会损坏转轴和轴套。
发明内容
本发明的目的就在于提供一种强度高，可靠性高，使用平稳，润滑方便，散热效果好的耐磨性齿轮轴套。本发明技术方案如下：
一种齿轮轴套，包括圆筒形的轴套本体，所述轴套本体包括钢外套和铜内套，钢外套套结在铜内套上，钢外套外表面设置有传动齿，铜内套内壁设置有纵向油槽和横向油槽，轴套本体上设置有注油孔，注油孔设置于纵向油槽和横向油槽连接处，轴套本体端部还设置有开口槽，在铜内套的内表面设置WC高致密陶瓷层耐磨涂层，该WC高致密陶瓷层的WC尺寸为20-40μm，体积分数达到90％以上，致密WC晶粒间组织为珠光体，并呈细长状结构分布。
所述传动齿设置在钢外套外表面中部。
所述开口槽的开口由轴套本体边缘朝内逐渐变大。
与现有技术相比，本发明的优点在于：本发明强度高、可靠性高、抗震动性强，使用平稳、润滑方便、散热效果好；轴套本体外层采用钢作为外层，内层采用铜作为内层，且在内层表面涂有WC高致密陶瓷层耐磨涂层，使齿轮轴套更加耐用，使用寿命更长。
附图说明
图1为本发明的结构示意图；
图2为图1的剖面图。
具体实施方式
下面将结合附图对本发明的技术方案进行描述，显然，所描述的仅仅是本发明一部分实施例。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。
