Reverse Rotation Application

For Electric Vehicle Reverse Rotation Applications

DC55.25 can also be applied in electric vehicle drive systems requiring reverse-direction torque control and one-way transmission functions.

Application advantages:

  • Directional torque control
  • Reliable locking performance
  • Compact installation design
  • High cycle durability

This component is installed inside the supercharger drive system, controlling power transmission between the engine and supercharger assembly.

The main functions include:

  • Transmitting engine power efficiently
  • Allowing one-direction rotation
  • Preventing reverse impact loads
  • Protecting the supercharger system during high-speed operation

Unlike conventional bearings, a one way clutch provides both rotational support and automatic locking performance.

When the engine drives the supercharger:

  • The rollers lock securely
  • Torque is transmitted efficiently
  • Supercharger operation remains stable

When operating conditions change:

  • The clutch releases automatically
  • Reverse load is reduced
  • Internal components are protected

The 6S5-17800-10-00 is widely used in Yamaha 1.8L supercharged marine applications, including WaveRunner personal watercraft and Jet Boat systems.

  • Long service life

Working Principle of Yamaha Supercharger One Way Clutch

The 6S5-17800-10-00 works through internal roller locking technology.

Drive Mode

When engine speed increases:

  1. Rollers move into the locking position.
  2. Inner and outer races engage.
  3. Engine torque drives the supercharger.

Freewheel Mode

When speed conditions change:

  1. Rollers release.
  2. Relative rotation is allowed.
  3. Shock loads are reduced.

This automatic engagement system improves supercharger reliability.
