Connecting Components


	*Configuration of connecting components*
	The cylindrical bore and outside surfaces of the clamping sleeve must be completely covered by the connecting components. To permit simple configuration of the connecting components, however, projection of the clamping sleeve up to max. a (Fig. 1 und 2) can be tolerated.

The manufacturing tolerance of the housing bore is H7; with high dynamic stress, for example in the case of a hydraulically actuated clamp, H6.

Manufacturing tolerance of the shaft: h5 (max. h6). The shaft and bore must be cylindrically machined with a mean peak-tovalley hight of Rz = 2,5 ... 6,3 microns. The functional surfaces of the connecting components, which are used to initiate clamping force in the clamping sleeves, must be manufactured with a run-out accuracy of 0.01mm or to IT4.

To ensure that the stress exerted on the hub or housing bore remains within the elastic range, we recommend the following minimum wall thickness:

C 45 steel = 0,6x(d2-d1)
aluminium-
alloys = 1,0x(d2-d1)
Minimum strength F 38
Only permissible when used as a
connecting element. Not suitable
in case of high alternating tension
and compression stress.
grey cast iron GG25 = 1,0x(d2-d1)
(shrinkage free cast)

Precise calculation of occuring housing tension levels is only possible within limits due to the complexity of different applications. In critical cases, we recommend executing a clamping test under operating conditions.
