The technical solution of the utility model is: this retarder comprises upper box, lower box, the primary input axle, secondary input shaft, main output shaft and secondary output shaft, adopt vertical layout, upper box and lower box constitute the speed reducer casing, primary input axle and secondary input shaft are installed in upper box, main output shaft and secondary output shaft are installed in lower box, primary input axle and main output shaft are coupled to each other by two reduction gear, secondary input shaft and secondary output shaft are coupled to each other by the level Four reducing gear, reducing gear comprises the driving cog axle, intermediate gear, center tooth axle and output gear, the driving cog axle connects input shaft, and output gear connects output shaft.

A kind of gear reducer that is used for water-plowing type aerator of the present utility model, the center line of major and minor input shaft and major and minor output shaft is parallel, and major and minor output shaft is coaxial, and secondary output shaft is a quill shaft, and main output shaft passes secondary output shaft.

A kind of gear reducer that is used for water-plowing type aerator of the present utility model, major and minor output shaft adopt two skeleton oil seals and the sealing of O type circle axial-radial.

A kind of gear reducer that is used for water-plowing type aerator of the present utility model, the bearing cap of lower box adopt the radial seal of O type circle.

A kind of gear reducer that is used for water-plowing type aerator of the present utility model, the two ends of every axle are fixed on the casing by deep groove ball bearing.

During use, main motor drives main output shaft by two reduction gear; Auxiliary-motor drives secondary output shaft by the level Four reducing gear again by the secondary input shaft of band drive synchronously; In this retarder, the main output shaft rotating speed is higher, and secondary output shaft rotating speed is lower but output torque is bigger, and it can be used on and requires coaxial and need in the machinery of different rotating speeds.

The utlity model has following advantage: 1. by the opposite end thrust of coming the balance engagement to produce with the gear rotation direction of the tooth axle on the same transmission shaft, each transmission shaft and input shaft adopt offset distance that the balance center of gravity is set, and make the complete machine can smooth running; 2. retarder adopts single phase motor to drive, and satisfies the demand of client to power supply; 3. output torque is big, and power requirements is lower; 4. retarder adopts the double input dual output, and mutual noninterference can be satisfied the requirement of " a tractor serves several purposes "; 5. two of retarder output shafts are coaxial, realized " axle " last two rotating speeds; 6. because under the situation that impeller type, blade type are worked simultaneously, water can absorb oxygen exponentially, and the oxygen content in the water can significantly improve, so the invention of this retarder has remedied the narrow limitation of single retarder in the past, can " a tractor serves several purposes ", cost can also economize on resources simultaneously; 7. adopt double input and double output shaft, two output shafts are coaxial, solved the requirement of two output shafts " coaxial different speed ", and it can be worked simultaneously, also can work independently, but mutual noninterference.
