Series AM Works Standard SN 05.01 >

High degree of axial preten- sion safely achievable. Designed with only mechanical components.High durability.High degree of efficiency, minimal tightening torque. Simple actuation.Application possible on high-speed spindles.Capable of withstanding dynamic loads. > Clamping nut screwed into place,slight contact of end face is sufficient. Clamping screw actuated: High axial forces have built up at the point of end face contact. Clamping screw released: Original slight contact of end face is restored.The principle is shown in a simplified diagram with enlarged clamping path. >

Fields of application: > Series AM clamping nuts are mecha-nical force transmitting elements for use in general mechanical enginee- ring. They are of particular benefit for the execution of reliable connections involving high axial forces using low manual forces.Designed to permit clamping andreleasing sequences in quick succes- sion without any trouble.The clamping nut is suitable for useon rotating spindles. Benefits: > During the clamping process (tigh- tening the clamping screw), no movement takes place at the end face and at the main thread of the clamping nut. This precludes the possibility...

The metric bolt thread must be pro-duced to tolerance class mediumē(tolerance class 6g, DIN 13, parts 21-25), for higher precision require- ments (as for spinning Spindles) to tolerance class fineē (tolerance class 4h, DIN 13, parts 21-25).If a high accuracy in centring theclamping nut is required, the diame- ter d > 2 has to be manufactured totolerance class h6.

Actuate the clamping screw,observing the max. tightening torque. Should no torque wrench be availa- ble, the clamping screw can also be actuated using a screwdriver ISO 2936 with normal manual force. In this case however, there is a tenden- cy for the clamping nuts in sizes only).2. Unscrew the clamping nut manually.In exceptional circumstances, forexample due to heavy soiling, it may be difficult to unscrew the clamping...

Fig. 3: Typical arrangement of the clamping nut on a tool fixture. Fig. 4: The machine component must be clamped here when in the operatio- nal status, but permit traversing for periodic set-up work. The clamping nut with thread fixation used here offers the advantage that its position remains fixed even when the nut is released. Fig. 5: Gear fixture with a clamping sleeve tensioned by a clamping nut. The gear has to be changed or its peripheral position altered periodi- cally. This can be conveniently and safely achieved using the clamping nut. >
