带内圈实体套圈滚针轴承BRI英制系列
带内圈实体套圈滚针轴承BRI英制系列,实体套圈滚针轴承是由一个或两个套圈以及带有保持架的滚针组组成。根据应用场合的不同,可分为带内圈或不带内圈的轴承。因此,实体套圈滚针轴承可以满足重量轻,占用空间小、传递功率大的要求。实体套圈滚针轴承具有较小的体积及较高的承载能力。
主要结构型式
外圈双挡边(或双锁圈)带保持架滚针轴承 NA、NKI型
可分别安装内圈和外圈(带锁圈、全套滚针和保持架),权限转速高,分单列和双列两种。
如果轴不能用来作为滚道,即若将轴淬硬用研磨不可能或不经济时,则可采用此类带内圈的滚针轴承。
无内圈有保持架滚针轴承
NA、NKI型轴承不带内圈即为RNA、NK型滚针轴承。
此种轴承无内圈,适用于径向安装尺寸受限制的支承结构,与轴承相配的轴颈直接作为滚动面。作为滚道面的轴,必须淬硬件并进行研磨,而且只有将其加工到适当的尺寸和形状精度时,整套滚针轴承才能较高的寿命及运行精度。同时,由于无内圈,因此轴的直径也可作适当加大,从而也增加了刚性。
带或不带内圈的密封滚针轴承
单面或双面密封的滚针轴承可以有效地防止脏物的侵入,轴承内已填入适量的锂基润滑脂。该类轴承的内圈比外圈宽,这使得轴承在轴相对轴承箱有微量位移时也可保证密封良好而免致轴承受污染。轴承的内圈也有润滑油孔,可以根据配置的需要,由外圈或内圈补充润滑。
