Embodiments disclosed include a continuously variable transmission (CVT) where power is transmitted from a group of balls (1) to a shaft (602) via an idler (18). In one -application, the CVT couples to a gearbox and to a generator of a wind turbine (688) . Traction elements of a CVT can be coated and/or textured, using various coating materials and textures, via disclosed coating and/or texturing methods. Methods and systems for shifting a CVT are disclosed. Certain components for a CVT are disclosed. For example, in one embodiment, a CVT includes a shaft (624) having a spline (628) and a shift flange (609) . In another embodiment, a CVT includes a stator (658) adapted to cooperate with shifter components. Disclosed is a CVT configured to produce a variable output speed that is always greater than an input speed. In one embodiment, a CVT produces a variable output speed that is always lower than an input speed. |
