[0037] like Figures 1 to 5 As shown, this embodiment provides a reducer connecting device for connecting a funnel-shaped reducer to a bearing (not shown in the figure), the connecting device includes a bearing connecting set 1 and a plurality of support plates 2, a plurality of slots 141 extending along the axial direction are arranged on the outer peripheral surface of the bearing connecting set 1, the plurality of slots 141 are arranged at intervals from each other along the circumferential direction of the outer peripheral surface, and the bearing connecting set 1 is sleeved on the bearing; the plurality of support plates 2 are inserted into the plurality of slots 141 one by one, and the end of the support plate 2 facing away from the slot 141 is connected to the inner wall of the reducer 100.

[0038] The reducer connection device provided in this embodiment connects the support plate 2 to the inner wall of the reducer 100, sleeves the bearing connection set 1 on the bearing, and then plugs the support plate 2 into the slot 141 on the bearing connection set 1, thereby realizing a stable connection between the reducer 100 and the bearing; since the support plate 2 and the bearing connection set 1 are located between the bearing and the reducer 100, the inner wall of the reducer 100 is supported and fixed, which can prevent the reducer 100 from being deformed; the plug-in between the support plate 2 and the slot 141 makes it easy to remove the reducer 100 connected with the support plate 2, so as to facilitate the maintenance and replacement of the reducer 100. The reducer connection device proposed in this embodiment can ensure the stability of the connection, so that the reducer 100 is not easy to deform, and it is convenient to repair and replace the reducer 100.

[0039] Specifically, the bearing connection set 1 includes a sleeve 11 and a mounting member 12 fixedly inserted into the sleeve 11 . A slot 141 is provided on the outer side of the sleeve 11 , and the mounting member 12 is sleeved on the bearing.

[0040] Specifically, the bearing connection set 1 further includes a plurality of connection plates 13, the two ends of which are respectively connected to the inner side wall of the sleeve 11 and the outer side wall of the mounting member 12, and the plurality of connection plates 13 are arranged at intervals from each other along the circumference of the mounting member 12. The plurality of connection plates 13 realize a firm connection between the sleeve 11 and the mounting member 12. In this embodiment, the two ends of the connection plate 13 are respectively welded to the sleeve 11 and the mounting member 12.

[0041] More specifically, the mounting member 12 is provided with a mounting hole 121, and the mounting member 12 is sleeved on the bearing through the mounting hole 121. Figure 6 and Figure 7 As shown, an opening 122 is respectively formed at both ends of the inner wall of the mounting hole 121 for sleeve connection with the bearing.

[0042] Optionally, a plurality of connecting plates 13 are evenly distributed along the circumference of the mounting member 12. This further ensures the firmness of the connection between the sleeve 11 and the mounting member 12. In this embodiment, eight connecting plates 13 are provided, and the angle between every two adjacent connecting plates 13 is 45°. Of course, the number of connecting plates 13 may also be other, which is not specifically limited here.

[0043] Specifically, the outer peripheral surface is a cylindrical surface, and the support plate 2 is a right-angled trapezoidal plate. In this embodiment, the sleeve 11 and the mounting member 12 are both cylindrical tube structures, and the two have a common central axis. The connecting plate 13 is a rectangular plate, and the oblique waist of the right-angled trapezoidal plate is welded to the inner wall of the reducer 100, and the right-angle waist is inserted into the slot 141, so that the mounting member 12, the connecting plate 13, the sleeve 11, the support plate 2 and the reducer 100 are closely abutted, achieving support for the inner wall of the reducer 100 and preventing it from deforming. Figure 5 As shown, the oblique waist of the support plate 2 is connected to the inner wall of the reducer 100 , so that the right-angle waist of the support plate 2 extends vertically, which is convenient for plugging into the slot 141 .

[0044] Specifically, in the axial direction of the reducer 100, the length of the bearing connection set 1 is smaller than the length of the reducer 100, one end of the bearing connection set 1 is flush with the large diameter end of the reducer 100, and the other end is spaced apart from the small diameter end of the reducer 100. In this embodiment, the lengths of the sleeve 11, the mounting member 12, and the connecting plate 13 in the bearing connection set 1 are all the same, which are all smaller than the length of the reducer 100, and since the support plate 2 is a right-angle trapezoidal plate, the bottom end of the sleeve 11 is spaced apart from the inner wall of the reducer 100, so that the material to be processed entering between the inner wall of the large diameter end of the reducer 100 and the sleeve 11 can flow out through the bottom of the sleeve 11 and the small diameter outlet of the reducer 100 in sequence.

[0045] More specifically, in the axial direction of the reducer 100, the length of the support plate 2 is the same as the length of the bearing connection set 1, and the two ends of the support plate 2 and the bearing connection set 1 are flush with each other. This arrangement makes the connection between the reducer 100 and the sleeve 11 more stable without affecting the smooth flow of the material to be processed.

[0046] Optionally, in other embodiments, the slots 141 may be provided on the outer circumferential surface of the sleeve 11 , and may be provided through the outer circumferential surface along the axial direction, so that all right-angle waists of the support plate 2 are inserted into corresponding slots 141 .

[0047] Specifically, in this embodiment, the bearing connection set 1 further includes a plurality of pairs of slot plates 14, which are arranged on the outer peripheral surface of the bearing connection set 1, and the interval between two slot plates 14 in each pair of slot plates 14 forms a slot 141. In this embodiment, the slot plates 14 are welded to the outer side wall of the sleeve 11, and this arrangement does not affect the strength of the sleeve 11. The slot plates 14 can be long strips with the same length as the sleeve 11 to form a through slot 141, or they can be Figure 2 As shown, every two pairs of slot plates 14 facing each other in the axial direction are correspondingly plugged into a support plate 2. This arrangement not only ensures stable plugging, but also plays a role in saving materials.

[0048] Optionally, a connecting plate 13 is correspondingly provided on the inner side of the sleeve 11 where each slot 141 is located, so as to further ensure the stability of the support of the reducer 100 .

[0049] like Figure 1 and Figure 3 As shown, there are an even number of slots 141, and a slot 141 is correspondingly arranged at the other end of the diameter of the bearing connection set 1 where each slot 141 is located. Accordingly, a support plate 2 is arranged at a position corresponding to the slot 141, as shown in FIG. Figure 1 As shown, two support plates 2 and two connecting plates 13 form a diameter of the reducer 100, which further ensures the stability of the overall structure and further avoids deformation of the reducer 100. In this embodiment, four support plates 2 are provided, two of which are symmetrically arranged with respect to the central axis of the sleeve 11, and two adjacent support plates 2 correspond to two adjacent connecting plates 13, so the angle between the two adjacent support plates 2 is 45°. Of course, the angle between the two adjacent support plates 2 can also be 90°, in which case the four support plates 2 are evenly distributed around the circumference.
