[0031] Please refer to the instruction manual appendix. Figures 1-5 This utility model provides a technical solution:

[0032] Example 1: A tapered roller bearing anti-disintegration clip includes a support 3 for vertically supporting the tapered roller bearing 1, and several clips 2 for locking and limiting the outer ring 12 and inner ring 11 of the tapered roller bearing 1. The support 3 includes a base plate 31, side plates 32, and support bolts 33. Two parallel and corresponding side plates 32 are vertically arranged on the upper surface of the base plate 31. The distance between the two side plates 32 is slightly larger than the width of the tapered roller bearing 1, and the height of the side plates 32 is also slightly larger. The thickness is greater than the sum of the thickness of the inner bearing roll 11 and the outer ring 12 of the tapered roller bearing 1. Several support bolts 33 are provided between the two side plates 32 to support the tapered roller bearing 1. Specifically, there are at least two support bolts 33. The support bolts 33 are distributed in an arc shape at the lower position between the two side plates 32. In order to facilitate the installation and adjustment of the support bolts 33, the threaded end of the support bolt 33 passes through the side plate 32, and a matching nut is threaded to its end.

[0033] The buckle 2 includes a U-shaped frame 21, a buckle bolt 22, an inner ring positioning screw 23, and an outer ring positioning screw 24. The open end of the U-shaped frame 21 is detachably equipped with a buckle bolt 22 for sealing the open end. The buckle bolt 22 passes through both side walls of the U-shaped frame 21 and is threaded with a matching nut at its threaded end. One side wall of the U-shaped frame 21 is provided with an inner ring positioning screw 23 that passes through the side wall and is connected to the lifting hole on the end face of the inner ring 11 of the tapered roller bearing 1. The other side wall of the U-shaped frame 21 is provided with an outer ring positioning screw 24 that passes through the side wall and is connected to the lifting hole on the end face of the outer ring 12 of the tapered roller bearing 1.

[0034] When assembling and displaying the tapered roller bearing 1, pass the U-shaped bracket 21 through the inner and outer rings of the tapered roller bearing 1, and install the snap-fit ​​long bolt 22 to enhance the stability of the U-shaped bracket 21. Then, tighten the inner ring positioning screw 23 into the lifting hole of the bearing inner ring 11 to position the bearing inner ring 11. Screw the outer ring positioning screw 24 into the lifting hole of the bearing outer ring 12 to position the bearing outer ring 12. After the snap-fit ​​2 is installed, place the tapered roller bearing 1 vertically between the two side plates 32 so that the outer diameter of the tapered roller bearing 1 rests on the support bolt 33 for display.

[0035] In Example 2, to improve the locking of the buckle 2 on the outer ring 12 and inner ring 11 of the bearing and prevent the tapered roller bearing 1 from coming apart, a buckle clamping screw 25 with a thread passing through the side wall of the U-shaped bracket 21 and abutting against the end face of the outer ring 12 of the bearing is provided. After the inner ring positioning screw 23 and the outer ring positioning screw 24 are installed, the buckle clamping screw 25 is screwed until it abuts against the end face of the outer ring 12 of the bearing. Preferably, due to the characteristics of the tapered roller bearing 1 structure, after the inner ring positioning screw 23 passes through the side wall of the U-shaped bracket 21 and connects with the lifting hole on the end face of the inner ring 11 of the bearing, there will be a certain gap between the end face of the outer ring 12 of the bearing and the U-shaped bracket 21. Therefore, the length of the outer ring positioning screw 24 should be slightly greater than the length of the inner ring positioning screw 23, and the buckle clamping screw 25 should also be set on the same side as the outer ring positioning screw 24.

[0036] In Example 3, to ensure the stability of the tapered roller bearing 1 on the support 3, several reinforcing ribs 35 that cooperate with the base plate 31 are provided on the opposite sides of the two side plates 32. Several support bolts 34 located on the upper part of the inner ring 11 of the bearing and distributed in an arc shape are also provided between the two side plates 32. The threaded end of the support bolt 34 passes through the side plate 32 and has a matching nut at its end. The support bolts 34 can limit the tapered roller bearing 1, preventing the tapered roller bearing 1 from falling out of the support 3. Several support clamping screws 36 with threads passing through the side plates 32 and abutting against the end face of the outer ring 12 of the tapered roller bearing 1 are also provided on the opposite sides of the two side plates 32. The support clamping screws 36 can further prevent the tapered roller bearing 1 from shaking.
