| description | The utility model discloses an eccentric transmission shaft of a small-caliber electric submersible screw pump reducer. The problem that the performance of the transmission shaft of the small-caliber electric submersible screw pump reducer is reduced is solved. The eccentric transmission shaft comprises a transmission shaft body, and is characterized in that the middle of the transmission shaft body is respectively provided with eccentric bodies integrated with the transmission shaft body from the front to rear; and the two eccentric bodies are vertically arranged in a staggered mode. A transmission shaft is replaced by the eccentric transmission shaft of an integral structure so as to replace a split structure of a reducer transmission shaft, an eccentric sleeve and a key. During operation, because the eccentric sleeve and the key are canceled, a key groove is not needed to be formed in the eccentric transmission shaft, and compared with a traditional transmission shaft of which the shaft diameter is increas |
