Safety Coupling - Direct

Safety Product

Information

 DIRECT DRIVE

Direct drive type rolling safety couplings for the direct attachment of toothed belt pulley, gear wheel, sprocket wheel, flange or brake drum with integrated ball bearings are offered for optimal constructional adjustment.

 

Direct drive type safety couplings are modular system consists of four standard types namely Rolling, Friction and shear. Several special solutions for nearly every application with various attachments can be fitted to the basic safety mechanism as required by the application.

 

For direct drives, the safety mechanism is connected to any type of application. The most important criteria for selection is the required disengagement torque, torsional stiffness, shaft diameters, assembly conditions, and shaft misalignment.


Working principle / specification

Technical Information

Safety couplings are designed for nominal break points or as overload protection in a direct or indirect drive application. The heart of the safety coupling is a highly precise, sturdy disengagement mechanism.

with steel balls as spring loaded positive locking elements. The drive torque is guided into the centrally arranged hub via a frictional, backlash-free lateral clamping hub or conical bush connection. The hub is designed as a ball cage and serves for fitting the flange ring and the shift disk. Special cup springs press the balls over the shift disk into hardened countersunk holes (calotte) of the flange ring. In normal operation, the drive torque is transferred without backlash into the flange ring. For further transfer of the torque and speed, a choice of compensation elements (metal bellows, elastomer spider), a gear or pulley or an appropriate connection flange is fit to the flange ring. If the set disengagement torque is exceeded in the case of crash or collision, the flange ring turns in relation to the cage hub and the balls are abruptly pushed out of the holes. The drive train is cut-off within a few milliseconds.


Direct drive rolling safety couplings are available in following five types

a.    Flange Type

b.    Sprocket Type

c.    Gear Type

d.    V Pulley Type

Brake Drum Type
