Title: Built-in Gearbox of Synchronous Motor Abstract The present invention relates to a built-in gearbox of a synchronous motor, consisting of a front end plate, a rear end plate, a positioning device provided between the front end plate and the rear end plate, an input shaft, an output shaft, and a reduction gear provided between the input shaft and the output shaft. The positioning device consists of sleeves and supports that are provided in the sleeves and fixed to the front end plate and the rear end plate. The sleeves of the positioning device are constant in length and the two ends of the sleeves are resisted against the inner surfaces of both the front end plate and the rear end plate. The length of the supports between the front end plate and the rear plate is less than or equal to that of the sleeves. ------------ / i I~ |
