Technical Field
[0001] The present application relates to a stirring device, and in particular to a stirring reduction motor. Background Art
[0002] A dough kneading machine is a mixing device widely used in the bread and noodle industries for mixing flour or kneading dough. In the related art, the dough kneading machine includes a frame, a mixing bin detachably mounted on the frame for arranging flour, a mixing reduction motor mounted on the frame, and a mixing rod mounted on the output shaft of the mixing reduction motor and extending into the mixing bin. The mixing rod can rotate on its own when driven by the mixing reduction motor, thereby achieving mixing of flour or kneading of dough. Since the above-mentioned mixing reduction motor can only drive the mixing rod to rotate on its own, the mixing effect of the mixing rod on flour or dough is limited. In view of the above-mentioned related art, the inventor believes that it is necessary to provide a mixing reduction motor with a more ideal mixing effect. Utility Model Content
[0003] In order to improve the stirring effect of the stirring rod on flour or dough, the present application provides a stirring reduction motor.
[0004] The present application provides a stirring reduction motor, which adopts the following technical solution:
[0005] A stirring reduction motor comprises a motor housing, a first motor mounted on the motor housing, an output mechanism mounted on the motor housing, and a reduction mechanism connecting the first motor and the output mechanism; the reduction mechanism has a reduction output shaft; the output mechanism comprises a central gear fixed to the motor housing, a rotating output frame mounted on the reduction output shaft, and a terminal output shaft rotatably mounted on the rotating output frame; the central gear is coaxially arranged with the reduction output shaft; the axis of the terminal output shaft is parallel to the axis of the reduction output shaft, and the terminal output shaft has a first gear portion that cooperates with the central gear.
[0006] By adopting this technical solution, when the stirring reduction motor is in operation, the first motor transmits torque to the output mechanism through the reduction mechanism. The rotating output frame in the output mechanism is able to rotate, causing the terminal output shaft to revolve along with the rotating output frame. The terminal output shaft also rotates due to the coordination with the central gear. Through the revolution and rotation of the terminal output shaft of the stirring reduction motor, the stirring rod in the dough kneading machine is mounted on the terminal output shaft, improving the stirring rod's mixing effect on flour or dough.
[0007] Optionally, the rotary output frame is mounted on a transmission sleeve on the reduction output shaft and a rotating disk connected to the outside of the transmission sleeve and coaxially arranged with the reduction output shaft, and the motor housing is mounted with a first oil seal that cooperates with the rotating disk.
[0008] By adopting the above technical solution, the cooperation between the rotating disk and the first oil seal makes the rotation stability of the rotating output frame ideal, and the first oil seal seals the gap between the motor housing and the rotating output frame, which helps to improve the waterproof performance of the above stirring reduction motor.

[0016] By adopting the above technical solution, the second oil seal seals the lower end opening of the rotating sleeve, which helps to improve the waterproof performance of the above stirring reduction motor.
[0017] Optionally, the motor housing includes an upper housing, an intermediate housing and a lower housing; a deceleration chamber for installing the deceleration mechanism is formed between the upper housing and the intermediate housing; an output chamber for installing the output mechanism is formed between the intermediate housing and the lower housing.

[0021] Optionally, the intermediate housing is provided with a mounting protrusion ring on the bottom surface and on the outside of the intermediate through hole for mounting the central gear, and a plurality of first threaded holes are arranged circumferentially at intervals on the end face of the mounting protrusion ring; the central gear has a gear through hole arranged corresponding to the first threaded hole and a first bolt that cooperates with the first threaded hole is installed at the gear through hole.
[0022] By adopting the above technical solution, the specific structure of the center gear in the intermediate housing is disclosed, and the center gear is fixed to the mounting convex ring by multiple first bolts, so the mounting strength is high, which makes the probability of the center gear loosening low.
[0023] Optionally, the output shaft of the first motor has an output gear portion, and the reduction mechanism also includes a first gear shaft rotatably mounted on the motor housing, a first reduction gear mounted on the first gear shaft and in transmission cooperation with the output gear portion, and a second reduction gear mounted on the reduction output shaft and in transmission cooperation with the first gear shaft; the first gear shaft also has a reduction gear portion that cooperates with the second reduction gear.
