| Summary: | Continuous Variable Transmission (CVT) system provides a solution that enable the
generation of staples shifting of gear ratio regardless of the speed and torque
requirement. CVT technology had been available since century ago, and it become
popular among the luxury car. However, due to the certain limitation of current CVT
design, CVT are not popular among the machineries. In this paper, Autodesk Inventor
was used to develop a new concept of compact CVT with simple and compact.
According to David G. Ullman, there are five steps in design process which start with
determine of problems, planning, develop design requirement, evaluation, decision, and
lastly communication of the result. Selection of the design had been going thru several
processes such as House of Quality (HoQ), and development of Engineering Design
Specification (EDS). In order to finalize the design, morphological chart with weighted
rating method had been used. New concept of compact CVT that had been developed is
less complicated compare to existing CVT system. In this new concept of compact CVT,
two unit of curved surface cones are used. One unit of idler located between two cone
act as rotation transmitter in this compact CVT. In addition, multiplication of the gear
ratio can be achieved by using multiple cone concepts. |
