自润滑复合材料卷制轴套
概述
概述 |
---|
自润滑复合材料轴套是由塑料、青铜、钢背通过烧结、塑化、辊轧(塑料能压入多孔青铜球粉层内)等工艺卷制而成的。分JH1型和JH2型,二者其中间青铜层均是多孔青铜球粉层,外层均是带镀层的钢背。二者的主要区别是内层,JH1内层是聚四氟乙烯(PTFE)+铅(Pb)及其他充填物,适用温度范围大,使用较广;JH2内层是改性聚甲醛(POM),表面轧出一定规律的储油坑,适用温度范围小一些,是较好的边界润滑材料,多用于停止、启动频繁的场合,安装时需在储油坑中填满润滑脂。二者主要性能及应用见表自润滑复合材料卷制轴套的性能及应用。卷制轴套的标准有GB/T 12613.1—2011(尺寸)、GB/T 12613.2—2011(外径和内径的检测数据)、GB/T 12613.3—2011(润滑油孔、润滑油槽和润滑油穴)和GB/T 12613.4—2011(材料)。 |

特
点 |
JH1型及 其派 生型 |
(1)静、动摩擦因数接近,防爬、减爬(即防粘滑运动)性能优良。适用于机构中微量进给、低速运动和重复定位要求较高的地方 (2)摩擦因数小,并能在无油、少油的工况条件下正常工作,能简化润滑系统,减少维护。安装时抹上润滑脂,使用效果更好 (3)能吸收振动,减少运动中的噪声。不产生聚积静电 (4)化学性能稳定,在对钢背材料进行特殊处理或采用不锈钢后,能在酸、碱、盐水溶液中或SF6气体、电弧分解物的气氛中工作。如印刷,造纸机械、化工设备、海洋机械、高压开关等,在JH1基础上开发的其他型号有: JH1G改进型——有更低的摩擦因数,能承受更大瞬时速度的变化和载荷的变化。适用边界润滑、无油、少油的轴承部位,如汽车减振器等 JH1Z增强型——有更高的承载能力和良好的抗磨损性能,是为高pv值而设计的,如齿轮泵、叶片泵、柱塞泵等 JH1W无铅型——采用不含铅的改性PTFE减摩层,适用于食品、医疗机械和家用电器等 JH1T铜背、JH1B不锈钢背等,具有良好的导热性和耐腐蚀性,可用于冶金、化工、海洋等环境,此外,还可制成翻边轴套、止推垫圈、球型轴承、机床导轨板等 |
|||||
JH2型 |
安装时在油坑中充满润滑脂,使用中定期加入润滑脂或稀油,效果更好。具有优良的耐磨性,适用于边界润滑条件,特别适合重载、低速停止、启动频繁不能形成润滑膜的旋转运动、摆动等机械的轴承。轴套可根据使用精度要求,在安装后对减摩层进行精加工。除轴套外,还可制成止推垫圈、机床导轨板等,其派生型为JH2W无铅型、JH2G改进型。JH2含铅型较JH2W有较好的耐磨性 |

装 |
JH1、JH2型自润滑复合材料轴套的安装注意事项: (1)轴套座孔及轴劲尺寸偏差的选择,可按表JH1型轴套尺寸中的推荐值选取。特殊环境可由试验来决定其合理间隙 (2)与轴套内径相配合的轴颈表面粗糙度Ra≤0.8μm,表面硬度≥46HRC (3)轴套座孔的表面粗糙度要小于Ra1.6μm。轴套座孔的压入端面应按T×20°倒角,并去除毛刺,涂少量的润滑脂以利于压入。轴套压入时,应先自制一个导向杆,用专用工具或压力机垂直地压入轴套座孔,应避免直接敲打轴套的端面。对导向杆、座孔的要求见下图 (4)JH1轴套内径工作表面(塑料面)不允许进行车、镗、磨、铰、刮等加工 (5)在安装轴套时,应避免轴套的接缝处在承受最大载荷的方向 (6)同一个座孔安装两个以上轴套时,轴套其接缝应在同一方向上,并对齐,且轴套之间应留有1~2mm的间隙 (7)当需要限制工作轴的轴向移动时,可加装止推垫圈或采用翻边轴套 |
