WFK型楔块式单向离合器

1、WFK型号为楔块式单向离合器，与GFK结构形式相同，外型尺寸与59系列轴承相同。

2、此型设计特点为在最小外径尺寸获得最大扭力。

3、内含黄油润滑及轴承支撑。

4、若要得到较好润滑效果而使用浸入油中的润滑方式，可以使用适当的方法，去除内含黄油，再安装入油池中使用。

5、不论何种油脂润滑方式，安装时均需外加油封以得较佳的效果，请参考下页安装范例。

6、以确保扭力之传输问题，必须以紧配方式安装，外圈与机壁为R6公差，内圈工作轴心为P5公差。

7、此重负荷紧配所产生的内缩小尺寸，设计时已考虑在内。

8、工作温度范围-40℃～+100℃，瞬间高温可达+120℃。

1、Type WFK is a sprag type freewheel, it’s construction is same as GFK, integrated into a 59 series ball bearing.

2、This design provides high toque capacity for minimal outside diameter.

3、It is bearing supported type, delivered grease lubricated.

4、Oil bath lubrication is also possible if the original grease is first removed by flushing the freewheel with a suitable solvent.

5、Whatever the lubrication type, seals should be provided, as illustrated on the next page.

6、Torque transmission must be ensured by a press fit assembly into a rigid outer housing with R6 tolerance and onto a shaft with P5 tolerance.

7、Initial radial clearance has been provided to take into account this heavy press fit.

8、Operating temperature range:-40℃to +100℃. Peaks up to +120℃ are acceptable for short periods. Please contact us for higher temperatures.
