Continuously variable toroidal drive, e.g. for vehicle or industrial machinery has thrust and roller bearing with several roller elements supported in pockets formed in circular holder

摘要

The toroidal drive has a thrust and roller bearing, with several roller elements supported in a holder (9). The holder has several pockets (11) formed in a circular main body, to hold the roller elements. An intermediate space formed between the pockets and the roller elements is 0.6-6 % of the spherical diameter of the roller elements. Preferably, the pockets are formed as a long hole with a cylindrical section and a spherical surface.
