Toroidal CVT POWERTOROS Unit
Overview
The Toroidal CVT is an innovative transmission that executes smooth, continuous gear ratio changes by changing the angle of the power rollers between the input disk and output disk. Toroidal CVT development began in 1877. One hundred years later, NMT undertook its development in 1978, spending as much as 21 years to develop a practical application. Featuring smooth, silent, and continuous gear ratio changes, as well contributing to conserving energy and further reduction of CO2 emissions, the highly efficient Toroidal CVT POWERTOROS Unit is the desired transmission that is a result of NMT's advanced technology in tribology.
FAQs
Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.
While DGBBs can handle axial loads in both directions, single-row angular contact ball bearings can only receive axial load in one direction.
Seals and shields offer additional protection for bearing components and help to improve and maintain lubrication. In terms of sealing performance, sealed bearings rank best, followed by shielded bearings, then finally open bearings. NMT uses supplementary designations D, DU, DW, and V (DD, DDU, DDW, VV) for sealed bearings and Z (ZZ) for shielded bearings. No supplementary designations are listed for open bearings.
