Combined clutch/brake units offer no wear

Combined clutch/brake units combine twet-running steel/sinter plates and the problem-free actuation of compressed air on power presses and guillotines, offering virtually no wear.

The Ortlinghaus clutch/brake combined units of series 0424 combine the advantages of the wet-running steel/sinter plates and the problem-free actuation of compressed air, i e, the plate stack suffers practically no wear and compressed air is already available in many factories.

They are suitable for the drives of presses, metalforming machine tools, guillotines and similar machines that work in cycles.

In particular they are suitable in cases where it would not be economic, or it does not appear appropriate, to make pressure oil available.

This series has been developed from the pressure oil actuated combined units of series 0123; it differs from these series externally in terms of its larger actuation cylinder, the greater size being necessary because of the lower operating pressures possible with compressed air.

The individual sizes can be supplied in various torque variations for clutch and brake.

The clutch is always available in a standard and also in a reinforced version.

In this way these units cover the low and medium range of the torque spectrum.

In the depressurized state springs push the piston of the actuation cylinder in the direction of the brake plates.

Studs mounted on the piston push the plates against a stop plate so that the brake is applied.

Engagement of the clutch Piston is subjected to compressed air, the air being supplied in general through the shaft.

The piston is moved away from the brake plates until it makes contact with the clutch plates and thus engages the clutch.

In clutch/brake combined units there is no overlap between brake and clutch.

The unit is secured to the shaft either with a key and keyway or with a locking assembly.

The type of sealing arrangement between the shaft and hub should be selected in accordance with the method of securing.

The combined unit is fitted in a sealed housing which can be supplied, if required.

Lubrication and cooling is carried out by splash lubrication, both circulation of oil through the housing or internal oiling through the shaft, are possible, the particular method being selected in accordance with the thermal load.

Appropriate rotary inlets for compressed air and oil are available.

The experienced project engineers recommend the most suitable product and will carry out the necessary calculations for each application.
