| 總結: | A new concept of gear train is proposed, namely the selective leverage gear system. It
is a unique primary gear system with levers, guided by an oblong to transmit force
from the power source in selective ways. Currently, no commercial product has existed
on the proposed gear system and modelling. The aim of this study is to investigate the
kinematics and evaluate static and dynamic behaviour of the leverage gear train so that
recommendations can be made for further developing work. The model was compared
with the experimental results of static using digital torque meter and for dynamic
torques Arduino with FSR approach is applied. For static analysis, results showed a
lower error distribution at position before 20°. Results showed that the dynamic output
torque was not as expected, which resulted in limitation to test speed at 30, 60, and
90rpm, but 30 and 90rpm came out with more precise results. It was observed that the
speed of the device was also limited by the lubrication and material properties of the
gears as well as the effects of load. These particular limitations may influence research
findings, but have not been focused in this initial study and should be considered for
future analytical and experimental work. Finally, conclude that prototype increase
output torque. |
