Toroidal continuously variable transmission
摘要:
Provided is a toroidal continuously variable transmission capable of preventing the application of bending stress to a variator shaft during rotation and the application of an eccentric load to each of support parts even when misalignment between the axis of a fitting hole formed in a post and the axis on which the variator shaft is supported occurs.A thrust bearing 12 which determines the position of an output side disc 10 in an axial direction and rotatably supports the output side disc 10 is fitted into a fitting hole 62b provided in a post 61, and a predetermined gap S is provided between the thrust bearing 12 and the fitting hole 62b in a direction perpendicular to the variator shaft 3. Therefore, even when misalignment between the axis of the fitting hole and the axis on which the variator shaft is supported occurs, the axes of the thrust bearing 12 and the variator shaft 3 can be aligned with each other in the predetermined gap S, thereby preventing the application of bending stress to the variator shaft 3 during rotation and the application of an eccentric load to each of support parts.
