Description

Technical Field

That is, at least a portion of the first bearing sleeve 30 and the first bearing sleeve 20 are stacked radially, thereby improving structural strength and providing better support for the first bearing 11. It should also be noted that the bearing support structure 100 provided in this application is easy to assemble. During assembly, the first bearing sleeve 20 and the second bearing sleeve 30 are first installed on both sides of the first bearing 11. After installing the end of the second bearing sleeve 30 into the first mounting groove 21 of the first bearing sleeve 20, the first bearing sleeve 20 is aligned with the preset position of the mounting base 40 and fixed. It is not necessary to align and fix the second bearing sleeve 30 and the first bearing sleeve 20 again, thus facilitating assembly and improving assembly efficiency.

[0051] The mounting base 40 has a mounting end 41 and a supporting end 42. The mounting base 40 also has a mounting hole 410 passing through the mounting end 41 and the supporting end 42.

The first limiting protrusion 32 is installed in the mounting hole 410, and the second limiting protrusion 33 is located between the first bearing sleeve 20 and the mounting base 40. It can be understood that the sidewall of the second mounting groove 31 of the second bearing sleeve 30 can also be referred to as a third limiting protrusion 34. The third limiting protrusion 34 and the first limiting protrusion 32 are respectively located on both sides of the second limiting protrusion 33 in the axial direction, and the diameters of the third limiting protrusion 34 and the first limiting protrusion 32 are both smaller than the diameter of the second limiting protrusion 33.

[0053] Specifically, the first bearing sleeve 20 has a plurality of first fixing holes (not shown in the figure) on its circumference, and the support end 42 of the mounting base 40 has a plurality of second fixing holes (not shown in the figure) corresponding to the plurality of first fixing holes. The bearing support structure 100 further includes a plurality of fixing members (not shown in the figure), which are installed in the first fixing holes and the second fixing holes for fixing the first bearing sleeve 20 to the mounting base 40.

[0054] refer to Figures 1 to 3The rotating end 13 of the rotating shaft 10 has a plurality of fixed protrusions 131, and a notch 132 is provided between adjacent fixed protrusions 131. The position of the notch 132 corresponds to the first fixing hole and the second fixing hole. The end of each fixed protrusion 131 has a fixing part 1311, which is adapted to install a roller. In this application, the notch 132 is provided between adjacent fixed protrusions 131 of the rotating end 13 of the rotating shaft 10. When the first bearing sleeve 20 and the mounting base 40 are fixedly connected by the fixing member, the notch 132 facilitates the operator's use of operating tools, thereby facilitating the assembly and disassembly of the first bearing sleeve 20.

[0055] refer to Figure 3 Furthermore, the outer surface of the first bearing 11 is a surface that is high in the middle and low at both ends. The surfaces of the first side portion 111 and the second side portion 112 of the first bearing 11 are both arc-shaped surfaces. The inner surface of the first groove 211 is an arc-shaped surface that matches the surface of the first side portion 111, and the inner surface of the second mounting groove 31 is an arc-shaped surface that matches the surface of the second side portion 112. It can be understood that designing the inner surface of the first groove 211 and the outer surface of the first side portion 111 as matching arc-shaped surfaces allows for both axial and radial positioning, and also increases the contact area between the first bearing sleeve 20 and the first bearing 11, improving the support effect on the first bearing 11. Correspondingly, designing the inner surface of the second mounting groove 31 and the outer surface of the second side portion 112 as matching arc-shaped surfaces allows for both axial and radial positioning, and also increases the contact area between the second bearing sleeve 30 and the first bearing 11, improving the support effect on the first bearing 11.

[0056] refer to Figures 4 to 6Further, the first bearing sleeve 20 includes a base plate 231 and a fixing plate 232 extending axially from the edge of the base plate 231 for a predetermined length.

The fastener can fix the fixing plate 232 to the side wall of the mounting base 40 on one side of the mounting base 40, thereby avoiding the rotating end 13 of the rotating shaft 10 when assembling or disassembling the fastener, which facilitates operation. Preferably, the fixing plate 232 surrounds the outside of the mounting base 40, or the fixing plate 232 forms a fixing groove around it, and the supporting end 42 of the mounting base 40 extends into the fixing groove. The fixing plate 232 is sleeved on the outside of the support end 42 of the mounting base 40, which can increase the structural strength of the mounting base 40 to a certain extent.

The fasteners can fix the first bearing sleeve 20 to the mounting base 40, and also fix the first bearing sleeve 20 and the mounting base 40 to one side of the application device 200, reducing the number of fasteners and improving assembly efficiency. In this embodiment, the fixing plate 232 surrounds the outside of the mounting base 40, providing support for the mounting base 40 and improving its structural strength.

[0058] refer to Figure 7Furthermore, the outer surface of the first bearing sleeve 20 has reinforcing ribs 234 extending from the fixing plate 232 and the first mounting plate 233. The reinforcing ribs 234 can increase the stability of the structure between the first mounting plate 233 and the fixing plate 232 and improve the structural strength of the first bearing sleeve 20.
