Merkel导向环 KB 型

产品特点

活塞用非金属导向环KB

工程机械，农用机械，注塑机械，装卸平台，支承油缸，

工业车辆，起重机，压机，冶金油缸

请遵守我们的通用设计准则 →参照技术手册

产品优点

1.活塞用非金属导向元件。适用于ISO 10766标准腔体沟槽：

2.金属/塑料材料匹配，可防止产生“滞塞”和“咬死”现象

3.受承载能力高，在达到脆性温度前仍具有弹性 (非塑性)

4.导向环棱边有倒圆角，防止棱边被挤进腔体沟槽倒角半

  圆处产生的间隙挤出

易于扣压装配（d≤300）

推荐应用

在切削深度c＝Rz/2和基准线Cref＝0％时，表面支承长度比Mr >50％至最大90％。

间隙尺寸

d1

h8

给尺寸D和d1规定的公差，必须与所用密封圈结合起来看

待。尺寸表规定的d1要相对导向环单独看待。相邻密封腔

体对应的直径，应该根据密封元件来修正。

生产公差

断面厚度S

–0,02 … –0,08 mm

表面负荷

p <50 N/mm2 60 °C 以下

p <25 N/mm2 100 °C 以下

线速度见密封系统。

 

在导向环上分布的压力是非线性的。在接触范围内的非线

性压力曲线，在计算表面允许比压的时候，已经考虑到

了。导向带上的允许负荷的计算方法是，表面允许比压乘

以投影面积。不过，表面允许比压的数值，假设用的是推

荐导向元件，则要考虑到活塞杆可能出现的偏斜角。

表面压力

F = P x A

H = F / (d x P)

H = 导向带宽度 [mm]

F = 允许负载 [N]

A = 投影面积 [mm2]

P = 表面允许比压 [N/mm2]

d = 当为活塞杆导向时，为活塞杆直径，或当为活塞导向

时，为活塞直径[mm]
