Description
Technical Field
The invention relates to the technical field of mixers, in particular to a planetary transverse support mechanism capable of adjusting revolution and rotation speed ratios and a mixer adopting the planetary transverse support mechanism.
Background
The existing stirrer in the market at present mainly drives a transverse support to revolve through a motor and drives a rotating cup to rotate through gear transmission, so that material mixing and stirring are realized. The conventional transverse support structure has two forms of fixed revolution-rotation speed ratio and adjustable revolution-rotation speed ratio.
The prior art proposes a cradle capable of adjusting revolution-rotation speed ratio, as shown in fig. 4 of the attached drawings, the cradle is provided with a rotation central gear 24, a transition spur gear 25, a transition bevel gear 26, a revolving cup lower bevel gear 27, a revolution driving wheel 28 and a rotation driving wheel 29, the cradle is driven to revolve by a revolution motor, the rotation motor drives the rotation central gear 24 coaxial with the revolution, and the gear drives the revolving cup lower bevel gear 27 to rotate by the transition spur gear 25 and the transition bevel gear 26, thereby realizing the rotation of the revolving cup.
The existing transverse support structure can realize that revolution and revolving cup rotate at different rotating speeds by adjusting the rotating speeds of a revolution motor and a rotation motor. Wherein, the revolution rotating speed is marked as n1 ', and the torque is marked as T1'; the rotation speed is marked as n2 ', and the torque is marked as T2'; the relative rotating speed of the rotor is marked as n4 ', and the torque is marked as T4'; the transmission speed ratio coefficient from the central gear to the revolving cup is k ', the value of k' and the number of teeth of the autorotation central gear 24, the transition straight gear 25, the transition bevel gear 26 and the revolving cup lower bevel gear 27 form a certain proportional relation, and then the rotating speeds satisfy the relation: n4 '/n 1 ' ═ k ' (n2 '/n 1 ' -1), and the relationship between the torques satisfies: t4 ' ═ T1 '/k ' ═ T2 '/k '. K' can be determined to be 0.5 according to the number of gear teeth.
When n2 '/n 1' is-1 to 0, that is, the rotation motor and the revolution motor rotate in reverse at a constant speed ratio, and the torque directions of T1 and T2 are always opposite from each other as can be seen from the torque relation. Namely, the revolution motor and the rotation motor keep positive output. At this time, n4 '/n 1' ═ 1 to-0.5, namely, revolution and reverse rotation of the rotor at this speed ratio, the system can keep stable operation.
When n2 '/n 1' is 0 to 1, that is, the revolution and rotation motors rotate in the same direction at a constant speed ratio, and the torque directions of T1 'and T2' are always opposite to each other as can be seen from the torque relation. Namely, one of the revolution motor and the rotation motor must output reverse torque (the technology cannot be realized). In actual operation, a motor is stalled or dragged to give an alarm, so that the system cannot operate stably. That is, the revolution and the cup speed ratio n4 '/n 1' calculated by the formula-0.5 to 0 cannot be realized.
From the above analysis, the conventional revolution-rotation speed ratio adjustable transverse support structure can only realize speed ratio adjustment within the range of 1-0.5, and speed ratio adjustment within the range of 0.5-0 cannot be realized. Here, 0.5 is used as a critical point of speed regulation, and the critical point of speed regulation occurs when the rotation speed of the rotating electric machine is 0, that is, n2 '/n 1' is 0. The speed regulation critical point n4 '/n 1 ' ═ k ' can change the speed regulation critical point value of the device by adjusting the tooth number of the transmission gear. However, no matter how the number of teeth of the transmission gear is adjusted, the value of k' never equals 0. That is, the speed regulation critical point exists forever, and the rotating speed mode with the speed ratio of 0 cannot be realized. Namely, the equipment can not work in the area with the speed ratio ranging from-k' to 0, and a speed regulation blind area exists.
In summary, although the conventional transverse support structure can realize the adjustment of revolution and rotation speed ratios, the speed ratio adjustment range realized by the structure is narrow, the rotation speed ratio adjustment of a full-speed section cannot be realized, and a speed regulation blind area exists. Meanwhile, the transmission structure also adopts the structural forms of a belt, a round belt, a synchronous belt and the like, but the transmission has the common characteristic that the revolution and rotation speed ratio can be adjusted, but the speed ratio adjusting range has a speed adjusting blind area.
The rotation speed is a key factor for determining the temperature rise of the material, the temperature rise of the material cannot be well controlled due to the fact that the rotation speed cannot be adjusted in a wider range, and the characteristic also determines that the existing stirrer can only be suitable for stirring and mixing part of the material, and the application range is small. Different revolution-rotation speed ratios are needed for materials with different viscosities, and the materials which cannot be suitable for a specific viscosity range are stirred due to the existence of a speed regulation blind zone, so that the application range of the equipment is reduced.
