Beier variable-ratio gear - Wikipedia

The Beier variable-ratio gear or Beier variator is a mechanical drive offering a continuously variable gear ratio between input and output. The gear relies on the inter-meshing of a number of thin disks. By varying their separation, the effective radius of one disk varies, thus changing the overall gear ratio. This varying-radius principle is shared by a number of other variatormechanisms. An advantage of the Beier is that a large number of disks may be

Continuously variable transmission - Wikipedia

A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds. CVTs are used in automobiles, tractors, motor scooters, snowmobiles, and earthmoving equipment.

How to calculate a gear ratio ? – x-engineer.org

The gear ratio i can be calculated in two ways: as a ratio between the number of teeth of the output gear and the number of teeth of the input gear. as a ratio between the base radius of the output gear and the base radius of the input gear. The base radius is measured from the gear center of rotation up to the point of contact of the teeth.
