Description

具有保持架的深沟球轴承 技术领域
本发明涉及轴承技术领域，尤其是一种具有保持架的深沟球轴承。
背景技术
由于新能源汽车驱动电机取代了传统燃油汽车的发动机，驱动电机成为新能源汽车的关键零部件，其相对于常规的电机通常要求：瞬时功率大、过载能力强、变速范围大，并能适应频繁启动、停止、加速、减速，低速爬坡是要求高转矩、高速行驶时要求低转矩。正是由于驱动电机的这些特性，决定了驱动电机轴承要比一般轴承的性能要求要高，要求其具备高速性能、急变速性、低力矩、低噪音、低温升、长寿命等性能。为了满足新能源汽车的急加速特性，具有较高转速性能的深沟球轴承常配套于驱动电机中。深沟球轴承中设置有保持架，保持架装配于内圈和外圈滚道之间，保持架通常具备环状主体结构和沿圆周均匀分布的球兜孔。球兜孔通常采用和球轴承的滚动体类似且曲率半径略大的凹球状面，并且在保持架主体的内径面和外径面分别开口。但是在使用过程中，在急加速或急减速的高速工况下，容易产生较高的温升，使得保持架出现融化裂解，以及保持架在兜孔或者其它位置容易产生冲击断裂，降低保持架整体的使用效果，同时现有的保持架组装生产不便，不利于提高生产加工效率。
发明内容
针对现有技术的不足，本发明提供了一种具有保持架的深沟球轴承，其结构简单，整体结构安装便捷，具有更高的稳定性，提高整体结构的使用效果和生产加工效率。
为实现上述目的，本发明提供了一种具有保持架的深沟球轴承，包括外圈、内圈、保持架和钢球，所述保持架设置在外圈与内圈之间，所述保持架上设置有兜孔，所述钢球设置在兜孔中，其特征在于：所述架体分体设置形成有上架体和下架体，所述上架体和下架体上均间 隔设置有兜槽，所述上架体和下架体上的兜槽对应组合形成兜孔，所述上架体于相邻兜槽之间设置有连接台，所述下架体于相邻兜槽之间设置有定位台，所述连接台与定位台之间设置有插接件和插接槽，所述插接件与插接槽相固定形成上架体与下架体的固定连接。
这样设置的有益效果是：这样设置，采用这种结构，保持架可以上下分开形成上架体和下架体，通过上架体和下架体可以便于钢珠的安装放置，并且两个架体通过连接件进行连接，连接便捷高效，同时结构简单，作为优选材料，分架体使用注塑材料，通常为PA66加上玻璃纤维、PA46加上玻璃纤维、PEEK加上玻璃纤维等材料，保证保持架的强度，同时结构质量较轻，便于维持轴承的稳定性，提高使用效果。
作为本发明的进一步设置，所述插接槽设置在下架体定位台上，所述插接槽中形成有隆起块，所述插接件设置在上架体连接台上，所述插接件端部形成有卡接块，所述卡接块卡设在隆起块与插接槽底面之间。
这样设置的有益效果是：这样设置，上架体和下架体通过插接件与插接槽的插接配合，同时插接件上卡接块会与隆起块相抵接，避免两者松脱，同时结构简单，连接便捷高效，
作为本发明的进一步设置，所述隆起块靠近插接槽插入口设置，所述隆起块与卡接块的接触面呈弧形面设置。
这样设置的有益效果是：这样设置，使得卡接块的卡接更为顺畅，提高安装生产的流畅性，提高生产加工效率。
作为本发明的进一步设置，所述插接件两侧形成有定位片，所述定位片弹性设置，所述插接槽对应定位片位置开设有容置槽。
这样设置的有益效果是：这样设置，可以使得两个分架体的连接更为紧密，不易发生松脱，同时通过定位片，在受到驱使两个分架体分离的力时，定位片可以提供反作用力，避免裂解，提高整体结构的稳定性。
作为本发明的进一步设置，所述插接槽通过容置槽与兜槽连通设置，所述容置槽中设置有储油棉。
这样设置的有益效果是：由于插接槽与兜槽连通，同时容置槽中设置有储油棉，在完成分架体的安装后，插接件两侧的定位片会卡入容置槽中，同时抵触储油棉，将储油棉抵触在钢球上，使得储油棉存储的润滑油液可以涂布在钢球上，从而起到对钢球的润滑降温，从而有效延长整体结构的使用寿命。
作为本发明的进一步设置，所述插接槽设置在下架体定位台上，所述插接件设置在上架体连接台上，所述插接件设置为两个连接臂，所述连接臂一端与连接台连接，另一端设置有卡钩，所述连接臂穿过插接槽设置，所述卡钩钩设在定位台外壁上。
这样设置的有益效果是：这样设置，连接臂连接更为紧固，增加整体的稳定性，同时双臂结构，不易发生松动，提高整体结构的使用效果。
作为本发明的进一步设置，所述卡钩呈楔形设置，所述卡钩与插接槽的接触面呈斜面设置。
这样设置的有益效果是：这样设置，将连接臂设置成这种结构，结构简单，连接效果好，同时卡钩与连接孔的接触面呈斜面设置，使得插入具有良好的引导效果，提升卡接效果，同时结构简单，利于实现。
作为本发明的进一步设置，两连接臂之间设置有连接桥。
这样设置的有益效果是：这样设置，使得连接臂的强度更高，不易发生变形，同时便于插入组装，提高整体结构的使用效果。
作为本发明的进一步设置，所述上架体上连接台矮于兜槽底面设置，所述卡钩长度小于连接台与兜槽底面距离差设置。
这样设置的有益效果是：这样设置，使得保持架整体结构布局更为合理，不会在安装时与防尘盖结构发生干扰，使得整体结构安装更为紧凑，提高整体结构使用的稳定性。
作为本发明的进一步设置，所述外圈内壁形成有第一连接台阶，所述内圈外壁形成有第二连接台阶，所述第一连接台阶与第二连接台阶之间卡设有防尘盖。
这样设置的有益效果是：保证对钢珠的遮蔽，提高整体结构的使 用效果，同时结构简单，利于实现，有效避免润滑油液的渗漏，增加整体的润滑效果，同时结构简单，利于实现。
