The machine component must be reliably clamped here during the operational status, but must 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.
- During the clamping process (tightening the clamping screw), no movement takes place at the end face and at the main thread of the clamping nut. This precludes the possibility of friction loss, thus eliminating the cause of the poor efficiency of conventional nuts.
- Only the clamping screw with its relatively small movement thread and the ball-bearing supports make some sliding movements. This results in high system efficiency. Combined with the double clamping force ratio, this enables reliable and user-friendly application of the clamping force.
- The entirely mechanical structure of the clamping nut guarantees long durability and makes it virtually impervious to the influence of temperature.
- Fields of Application
Series AM-GS clamping nuts are mechanical force-transmitting elements for use in general mechanical and construction engineering. They are of particular benefit for the execution of reliable connections involving high axial forces with a low level of manual force.
They are designed to permit clamping and release in quick succession without difficulty. The clamping nut is suitable for use on rotating spindles.
- High degree of efficiency, minimal tightening torque.
- Simple actuation.
- Can be used on rotating spindles.
- Capable of withstanding dynamic loads.
- High degree of axial pretension safely achievable.
- Designed with purely mechanical components.
- No hydraulics used, which means no leaks or sudden failures are possible.
- Excellent durability.
Ensure that the clamping screw is in the correct starting position. Under no circumstances may the clamping screw be screwed in below the surface of the housing before the clamping sequence begins. Otherwise it is not possible to utilise the full clamping path of 2 mm.
- Screw the clamping nut manually until it makes contact with the end face (Fig. 1), Tighten the fixing screws and lock the clamping nut to the thread.
- Tighten the clamping screw, observing the max. tightening torque. If a torque wrench is not available, the clamping screw may also be tightened using a screwdriver ISO 2936 (DIN 911) using normal manual force. If the clamping screw is tightened without a torque wrench, there is a tendency for the clamping force of the clamping nuts larger than M42 not to be fully utilised.
The clamping force of the nut is now fully effective. (Fig. 2)
- Turn the clamping screw back to the starting position. The clamped component is now released.
- If the clamping nut is to be completely removed from the spindle, the thread lock screws must now be released. Then unscrew the clamping nut manually.
In exceptional circumstances, for example due to heavy soiling, it may be difficult to unscrew the clamping nut. In this case, utilize the radial boreholes around the outside diameter to insert a guide pin.
