Therefore, the generator is an essential accessory in automobile production. The generator is arranged on the gear chamber of the engine through a mounting bracket. There is a power output shaft on the gear chamber, and the power output shaft is in transmission connection with the input shaft of the generator through belt drive; thus, while fixing the generator on the gear chamber, a belt tensioning structure also needs to be designed.
