| Summary: | The technology of metal pushing V-belt (MPVB) Continuously Variable
Transmission (CVT) is n o w commercially available in the market but to date the
questionable reliabilities and limited torque capabilities have inhibited their growth.
Belt slip is one of the major losses that cause inefficiency in CVT and limited the
t r a n s f e r r e d torque f r om the engine to the tyres. One of the factors that believe cause
this belt slip is because of unstable in oil lubricant behaviour especially due to
operate in high temperature and pressure. Therefore, this report presents the work
which has been carried out on designing a C V T Lubricant Test Device which capable
to investigate the phenomena of f i lm collapse in a C V T mechanism. Modern design
concepts and methods have been applied in designing this device where a five phase
design model as proposed by Eggert has been used. The five phase designs are
formulation, conceptual design, configuration design, parametric design and detail
design. The device is significant because, hence to study and investigate film
collapse, this device also capable to study and investigate the other specific
parameters which affect the transmission efficiency such as differ in contact angle,
contact area and material used. |
