The invention relates to a sewing machine for preventing thread jamming of a rotating shuttle and a rotating shuttle synchronous lubrication system of the sewing machine. The system is arranged on a rotating shuttle base which is used for mounting a rotating shuttle assembly. The system is characterized by comprising a synchronous gear which synchronously rotates with a rotating shuttle main shaft, a gear oil pump which is arranged on the rotating shuttle base and an oil tank which is communicated with the gear oil pump; the gear oil pump comprises a pump body, a pump cover and a set of oil pump gears which are meshed with each other; a set of oil pump gears are arranged in a containing cavity which is formed by the pump body and the pump cover, and the synchronous gear is arranged on a synchronous gear shaft which penetrates through the pump body and extends into the containing cavity; one oil pump gear is arranged on a synchronous wheel shaft, and the other oil pump gear is arrangedon the gear shaft parallel to the synchronous wheel shaft; the gear oil pump is communicated with a lubrication oil channel of the rotating shuttle assembly, and the length of an oil pipe used for making the gear oil pump and the lubrication oil channel communicated is smaller than 15 cm. According to the sewing machine, the service life of the rotating shuttle can be remarkably prolonged, and thread jamming of the rotating shuttle is prevented.
