CZ/CN Zero Backlash Safegard Overload Clutches
|
|
 |
Zero backlash Overload Clutches and Couplings, series CZ available in 8
different basic types and 12 basic sizes, for shaft diameters from 8mm to
60mm; providing overload protection for torque values from 5Nm to 740Nm.
The CZ series Safegard overload clutches were developed to provide a totally backlash free transmission of power with a very responsive overload protection. These compact units are directly interchangeable with existing designs in the market providing a cost advantage with long reliable service life. |
| Two basic modes of operation are available: | |
| 1.
The basic CZF Safeguard ratchetting design with the driving balls equally
spaced so that the clutch can re-engage after a small angle of rotation 2. The Synchron CZY design with the balls unequally spaced so that the clutch can only re-engage after a full revolution so providing full synchronisation between driver and driven Responsive overload reaction is obtained by the use of negative functioning disc springs to apply drive load. In the event of an overload the spring load actually decreases, allowing faster disengaging of the drive and minimal pressure on the driving surface in the disengaged mode.

CP Safegard Pneumatically operated Overload Clutches CP Clutches are zero backlash units which provide remote accurate adjustment of the overload torque by air pressure adjustment. The torque can be constantly adjusted throughout a production cycle providing optimum machine protection. CP Overload Clutches can be integrated into complex control systems with substantial advantage in automatic machinery with continuous changes of operating conditions. A stop switch is integrated in the torque limiter detecting the axial movement of the unit in event of an overload, providing a signal to cut off the air feed, to disconnect the drive. When overloaded, the CP Clutch has no connection between drive and driven sides providing a long maintenance free service life. After the cause of the overload has been removed the clutch can be automatically re-engaged by resumming the air pressure. Standard finish on the clutches is black phosphate exterior, but can supply in Nickel plated. CP Safegard Overload Clutches PDF Catalogue |
