HOW IT WORKS

Transferring Starting Torque While Allowing Automatic Disengagement

Starter clutch drives serve as the mechanical link between the starter system and the engine during startup. When engaged, torque is transmitted through the clutch assembly to rotate the engine and initiate the starting sequence.

As engine speed increases beyond starter speed, the overrunning clutch function allows the drive to disengage automatically. This prevents the running engine from back-driving the starter system while protecting starter components from excessive rotational speeds.

Positive Starter Engagement

Transmits torque from the starter system to the engine during startup.

High Torque Capability

Supports demanding turbine and reciprocating engine starting requirements.

Automatic Overrunning Function

Disengages once engine speed exceeds starter speed.

Starter System Protection

Helps prevent back-driving of starter components after startup.

The Hilliard Starter Clutch Drive utilizes a roller-ramp mechanism that locks during startup to transmit torque through the clutch assembly. Once the engine accelerates beyond starter speed, the clutch transitions into overrunning operation, allowing the engine and starter system to rotate independently.
