Description

Technical Field

[0001] The utility model relates to the field of dough mixers, in particular to a transmission gearbox structure of a dough mixer and a dough mixer. Background Art

[0002] The power device of a dough mixer usually includes a motor and a speed reducer. The speed reducer is used to reduce the rotational speed of the output end of the power device and increase the torque. However, the motor and the speed reducer are relatively large in volume. Considering the usage habits of the dough mixer, the motor and the speed reducer are generally coaxially arranged and installed along the longitudinal direction, so a relatively large installation space needs to be reserved in the longitudinal direction inside the dough mixer housing. As a result, the overall dough mixer needs to be made relatively tall, leading to a relatively large overall volume, increasing the manufacturing cost, and being inconvenient for users to store.

[0003] Moreover, the existing dough mixers generally use a worm and worm gear mechanism for transmission. The transmission efficiency of the worm and worm gear is relatively low and it is difficult to use. Further, this type of structure has relatively high requirements for the installation structure of the motor and the speed reducer. If the installation is unstable, gear meshing failure may occur, and even tooth breakage may cause gear damage. Summary of the Utility Model
