The utility model discloses a gearbox spindle head oil pump of a high-seed pump. The gearbox spindle head oil pump of the high-seed pump comprises an internal cycloidal gear and an external cycloidal gear, wherein the internal cycloidal gear sleeves the external cycloidal gear; the teeth of the external cycloidal gear are one less than the teeth of the internal cycloidal gear; the internal cycloidal gear is fixedly arranged; when the external cycloidal gear is driven to rotate by a motor, the tooth crest of the external cycloidal gear is in contact with or is separated from the internal cycloidal gear, so that oil can be squeezed out from a gap formed by the internal cycloidal gear and the external cycloidal gear. The gearbox spindle head oil pump of the high-seed pump is characterized in that due to the design of internal engagement of the internal cycloidal gear and the external cycloidal gear, the external cycloidal gear rotates along with the motor while the internal cycloidal gear is immobile so that a g
