In
current years, searching for substitute energy such as the wind and ocean
power of renewable energy is an important subject due to the petroleum
shortage. The gear box is the key mechanism in the system of
wind and ocean power. Moreover, the main function of the system is to
generate electricity by speeding up the rotative
velocity. However, the power of environment changes momentarily and makes the
turbine a variable input. In order to improve the efficiency of generating
electricity, it should get the constant input to keep the high quality of
generating electricity. First of all, the study focuses on the gear box and
synthesizes a constant speed mechanism of planetary gear train which degrees
of freedom is two. In the mechanism, inputs are the variable speed turbine
and a constant speed motor. When they input the mechanism, a constant speed
output will be made to supply the generator. Secondly, it is necessary to set
up the real object of the constant speed mechanism of planetary gear train.
Finally, observing the real condition from the experiment to prove the theory
is correct.
