Variator
A variator is a device that can change its parameters, or can change parameters of other devices.
The Evans friction cone, a type of cone ring transmission. Moving the friction ring between the two cones varies the effective gear ratio
Often a variator is a mechanical power transmission device that can change its gear ratio continuously (rather than in steps).
Examples
- Variator (variable valve timing)
- Continuously variable transmission
- Beier variable-ratio gear
- Evans friction cone
- Variomatic
- VANOS
