Abstract
A gear noise free toroidal continuously variable transmission is disclosed wherein in order to suppress occurrence of gear noise, a gear train is accommodated in a gear housing which includes a first housing part fixedly secured to a transmission casing and a second housing part fixedly secured to the first housing part to form a dual-walled structure.
Claims5
A toroidal continuously variable transmission comprising:
- a transmission casing;
- coaxial input and output discs having facing toric surfaces;
- a gear housing disposed within and fixedly secured to said transmission casing;
- and
- a gear train within said gear housing and including an output gear in driving connection with said output discs,
- said gear housing including a first housing part and a second housing part fixedly secured to said first housing part to form a dual-walled structure which is so constructed and arranged as to enclose said gear train to confine noise derived from said gear train therein.
