产品介绍

NTN滚针轴承是一种采用细长滚子(滚针)作为滚动体的轴承,以其特别的结构设计和紧凑的体积,在需要高承载能力且空间受限的场合中表现出色。滚针轴承适用于高速运转和承受高径向载荷的应用,如变速器、汽车引擎、齿轮箱等领域。滚针轴承采用直径小于6mm,且长度是直径的3~10倍的针状滚子作为滚动体(JISB1516滚动轴承 - 滚子)。因为滚动体为滚针,所以剖面高度小,但载荷能力大于同尺寸比例的其他类型轴承。滚针数量多,从而刚性大,也称之为适用于摆动运动的轴承。

产品特点

高承载能力:滚针轴承的细长滚子能够更有效地分散载荷,提高轴承的承载能力。

小体积:由于滚针直径小,轴承整体尺寸紧凑,便于在有限的空间内安装。

低摩擦:优化的滚道设计和滚动体材料选择,减少了摩擦和磨损,提高了轴承的运转效率。

高精度:采用高精度加工技术,确保轴承的尺寸精度和旋转精度,满足精密传动需求。

长寿命:符合标准的材料和精细的制造工艺,使得轴承具有较长的使用寿命。

常见型号

NTN滚针轴承的型号多样,大多数情况下根据内径、外径、宽度、滚针数量等参数进行分类。常见型号包括NK系列、NA系列、RNA系列等,每种系列下又有多种规格可选,以满足不同应用场景的需求。

工作原理

NTN滚针轴承的工作原理基于滚针在内外圈滚道之间的滚动。当轴承承受径向载荷时,滚针在滚道内滚动,将载荷均匀分布到整个接触区域,从而降低了接触应力,延长了轴承的使用寿命。与此同时,滚针轴承的滚道设计也考虑到了轴向定位的需求,确保轴承在运转过程中的稳定性。

应用行业

NTN滚针轴承广泛应用于多个工业领域,包括但不限于:

汽车工业:作为变速器、发动机、传动系统等关键部件的支撑和传动元件,提高车辆的性能和可靠性。

机床行业:在精密机床的进给机构、主轴支撑等部位使用,确保加工精度和效率。

航空航天:在飞机发动机、起落架等部件中,承受高速旋转和高精度要求。

自动化设备:在工业机器人、自动化生产线等设备中,提供高精度、高速的传动支持。

其他工业领域:如电力设备、重型机械、纺织机械等,满足各种复杂工况下的传动需求。
