轴承加热器 | |
轴承加热器的正确安装,可以保障轴承拥有很长的寿命。 如果对其进行正确的安装和维护,滚动轴承就是有长的使用寿命的可靠机械元件。 选用感应加热器加热后轴承以圆柱方向向外膨胀,可避免安装时的损坏。感应加热器为一种最科学的加热方式,它无需预热,根据轴承重量的不同可在数秒或数分钟内加热至110℃,不损坏预先的润滑 | |
轴承拉拔器 | |
轴承的安装状态为下列情况时,可采用专用拉拔器拆卸的方法拆卸。 (a)轴形状:圆柱轴轴承内圈内径形状:圆柱孔。 (b)轴形状:圆柱轴,使用紧定衬套轴承内圈内径形状:维孔。 (c)轴形状:维形轴,轴承内圈内径形状:维孔。无论哪种状态,拆卸时都必须松开轴的锁紧螺母(或緊定衬套锁紧螺母)的止动,将锁紧螺母置于松动的状态。 |
