FDC单向内芯

FDC单向内芯结构简图

产品特性及说明

1.本公司FDC型号为楔块保持器单向离合器，但不含内圈和外圈。结构形式如图所示，其扭矩大，噪音小，安装方便。

2.此型号必须配合客户之自行设计的内圈及外圈，轴承支撑轴向及径向的负载，润滑油脂及油封。

3.楔块接触面之空间公差必须在范围内，外圈与内圈之接触面的宽度不可小于尺寸"e",接触面不可有任何沟槽以确保功能正常。

4.原厂可提供标准式的内圈与外圈。

5.若自行制造经硬化处理过的钢制轴心及工件机壁直接套入，请参考以下之表面硬度规格。

6.研磨加工处理过的接触面硬度为HRC60~62°硬化深度必须大于0.6mm。

7.接触面之内部硬度为HRC35~45°,接触面之表面光滑度须小于22CLA，接触面可接受的外斜度在25mm与0.007之间。

1.Type FDC is a sprag type freewheel cage without inner or outer races. It’s model and construction is followed for, this type provides higher torque and lower noise while fixed convenient.

2.It must be installed in a design providing races, bearing support for axial and radial loads, lubrication and sealing.

3.The sprag space tolerance must not be exceeded. Inner and outer races must both have a minimum plain width“e”, without any recess, to ensure the freewheel functions correctly as shown on following pages.

4.We can offer standard inner and outer races, as shown on the following pages.

5.Alternatively, races can be made in case hardened steel shafts, or housings, to the specification below.

6.Surface hardness of the finished pargt should be HRC 60 to 62°, for a depth of 0.6mm minimum.

7.Core hardness to be HRC 35 to 45°. Surface roughness not to exceed 22CLA . Maximum taper between races:0.007mm for25mm Width.
