Continuously variable transmission
First Claim
1. A turbine powered system comprising:
- a turbine having a power output;
a continuously variable transmission coupled to the power output of the turbine, the continuously variable transmission comprising;
a plurality of speed adjusters;
a drive disk frictionally contacting the speed adjusters;
a driven disk frictionally contacting the speed adjusters;
a support member between the drive disk and the driven disk and frictionally contacting the speed adjusters;
a bearing disk adapted to provide rotational force to the drive disk;
a threaded member on the drive disk; and
a screw for engaging the threaded member, the screw positioned coaxial with and about a longitudinal axis of the continuously variable transmission.

Abstract
A continuously variable transmission is disclosed for use in rotationally or linearly powered machines and vehicles. The transmission provides a simple manual shifting method for the user. Further, the practical commercialization of traction roller transmissions requires improvements in the reliability, ease of shifting, function and simplicity of the transmission. The present invention includes a continuously variable transmission that may be employed in connection with any type of machine that is in need of a transmission. For example, the transmission may be used in (i) a motorized vehicle such as an automobile, motorcycle, or watercraft, (ii) a non-motorized vehicle such as a bicycle, tricycle, scooter, exercise equipment or (iii) industrial equipment, such as a drill press, power generating equipment, or textile mill.
