Toothed Jaw Clutches

Positive Engagement Clutches

Toothed jaw clutches, also known as positive drive engagement clutches, provide a simple and reliable method for connecting and disconnecting shafts with components like gears, pulleys, or rollers. These clutches feature precision-machined steel jaws with standard 3° tooth spacing (120 teeth) but can be customized with alternate spacing.

Dynatect offers two primary types: knob-operated D Series and lever-operated J Series.

Applications: Jaw clutches are commonly used in conjunction with sprocket wheels, gears, and pulleys due to their ability to engage and disengage while in motion.

Important Considerations: While jaw clutches are typically stronger than the driving shaft, determining the overall torque capacity requires evaluating all system components, including the shaft, bearings, motor, and other connected parts.

Mounting Options

jaw clutches mounting options

The above image illustrates three common mounting configurations for jaw clutches:

  1. Phase adjustment shaft to pulley: This configuration allows for precise adjustment of the relative position between the shaft and pulley.
  2. Prevent reversal gear: This setup incorporates a gear mechanism to prevent the shaft from reversing direction.
  3. Engage and disengage mechanism: This option provides a convenient way to connect and disconnect the clutch.

Each mounting option offers specific functionalities to suit various applications and operational requirements.
