BD-Series Single-Position Jaw Clutches

Overview:

These clutches are used wherever different sections of a machine need to be first disengaged from the drive train and then re-engaged while maintaining the same phase or angular relationship which existed prior to disengagement. They are often used in a line-shaft, between printing units on an offset-printing press, and to disconnect certain units on a finishing line.

The unit consists of two jaw assemblies mounted on separate shafts, each supported by two bearings, and enclosed in a rugged cast-iron housing. This type of construction insures fail-safe disengagement (it will not lockup if failure occurs in disengaged mode). The single-position engagement is achieved by providing two teeth with slightly different dimensions. Additionally, the unit offers minimum backlash and maximum torsional rigidity by using high-strength, case-hardened and ground, chrome molybdenum alloy steel for the jaws and slide-dog shifting elements. The clutch is actuated remotely by a pneumatic cylinder and limit switches, which is provided with the unit, or manually by a shifting lever.

For applications requiring single-position clutching in a right-angle version, the model RDB is also available.  Please consult factory for more information.
