Disc springs - Import export

Automatic clamping takes place over disc springs, which are adjustable in the pre-loading and are solved pneumatically to the workpiece change. Manual clamping is made by a knurled knob on the opposite side of the collet. Due to the integration into the existing through-hole of the rotary table, the rotary table with the clamping system remains very compactly. Compact High run-out accuracy Easy to operate Retrofit possible

The Compact Line includes spring-pressure single-disc brakes that can be mounted as complete units to the motor with very little assembly work. The compact design is of advantage when limited space complicates mounting. Electromagnetically-operated spring-applied brakes build up the braking torque when the current is switched off.

The VARIO LINE includes DC spring-pressure single-disc brakes, which can be matched to the individual application due to a wide range of variants. Electromagnetically-operated spring-pressure brakes build up the braking torque when the current is switched off. By means of the electromagnetic force or an additionally mounted hand lifting device, the braking effect can be neutralized. Fitting dimensions and the grading of the type series of the VARIO LINE are matched to IEC motors.

The Elevation Line includes both DC spring-pressure single-disc brakes as well as spring-pressure double-disc brakes which comply with EN 81 (Safety Regulations Concerning the Design and Installation of Elevators). Integrated micro-switches allow for remote inquiry of the brake condition (armature position, wear, armature bearing). Owing to the patented safety concept, the otherwise mandatory testing of the dual-circuit braking system of the spring-pressure brake at the approval of the elevator system can be dropped. The brake can be used in places where short construction lengths with respective system components like motor, gear and brake must be realized. The Elevation Line is primarily used for elevators, but can be used wherever the brake must meet demanding safety requirements. Electromagnetic spring-pressure brakes build up the braking torque when the current is switched off.

The Classic Line includes DC spring-pressure single-disc and multi-disc brakes which, due to their robust design and the variable connection technology, meet the requirements of demanding applications. Electromagnetically-operated spring-applied brakes build up the braking torque when the current is switched off and the electromagnetic force is therefore neutralized.

The EEX Line includes spring-pressure single-disc brakes provided with explosion protection for explosion-hazardous areas. The spring-pressure brake with firedamp protection is suitable for underground excavations with danger of firedamp. In spring-pressure brakes with explosion protection, those parts which might ignite explosive mixtures are incorporated in a housing. If the mixture inside the housing explodes, the latter prevents a transfer of the explosion to the mixtures surrounding the housing. The brake is equipped with four thermal circuit breakers and one micro-switch. The micro-switch prevents starting against the unlifted brake. The thermal circuit breakers are series-connected with the micro-switch and interrupt the control circuit of the machine as soon as there is an inadmissibly high temperature at the brake. The brake is seawater-resistant. By means of the attached hand lifting feature, the braking effect can be manually neutralized.

The spring-applied single-disc brakes in the Servo Line series are designed to operate dry. They can be mounted to the A-face or B-face end shield inside the servo motor. The braking action generated by the compression springs is neutralized by applying the electromagnetic principle involving generation of a magnetic field. The brakes engage in unpowered condition and release when DC voltage is applied. The brakes are equipped with a flange and firmly fastened with screws. Thanks to a specially developed and patented manufacturing method, the rated air gap tolerance can be reduced to a few hundredths of a millimetre, providing enhanced power. Moreover, the brakes have a toothed hub/friction disc connection with minimal circumferential backlash. Standard version is suitable for flange mounting and face mounting.
