There is a kind of generator with gear speed increasing mechanism, the rotating speed transmitted by planetary gear or biased gear to engine belt pulley carries out secondary speedup, can effectively improve the gearratio of generator, generator speed when vehicle idling and low speed is got a promotion.【 2 】But because fast ratio is still fixed value, in order to ensure bearing life, speed is than being limited to generator highest working speed, and fast ratio generally can not be more than 1: 5.
The efficiency characteristic of generator has peak value to rotating speed, has crossed the decline of peak value behind efficiency；Usual generator best efficiency point is in generator speed 2000rpm or so, and the rated power of generator turns left the right side 6000.The loss of generator is increased with rotating speed rise.【 3 】Because fast ratio is fixed value, and the rotating speed of engine is changing always with road conditions, and generator only has seldom time to operate in higher efficiency range.
