By adopting the arrangement, the damping block is connected with the rack of the generator through the mounting rack, so that the assembly difficulty between the damping block and the rack is favorably reduced, and the assembly use of the damping support is favorably realized.

A generator comprises a power unit and a rack, wherein any one of the damping supports is connected between the power unit and the rack. Compared with the prior art, the arrangement greatly prolongs the continuous working time of the generator from about 90 hours to more than 300 hours, even more than 500 hours in the prior art, thereby greatly improving the working performance of the generator; meanwhile, by adopting the arrangement, the structures of the existing generator except the damping support can not be adjusted, so that the problem that the cost of the generator is greatly increased for improving the working performance of the generator is solved.
