Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a tapered roller bearing. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Tapered roller bearings utilize their advantage of being able to bear both axial loads and radial loads, and are increasingly used on various main machines that require bearing installation.

[0003] In the traditional tapered roller bearing, when subjected to staggered axial forces, the inner ring and the outer ring will be separated, which makes it impossible to guarantee the concentricity of the equipment operation. Generally, a circlip is used to fix and limit it. However, in the case of large forces, due to the lateral force on the circlip and the lack of a fixing component at the opening, the circlip will be distorted and deformed, and in severe cases, it will directly burst open, which is not conducive to the stable operation of the equipment. Summary of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a tapered roller bearing, which can solve the problem that in the case of large forces, due to the lateral force on the circlip and the lack of a fixing component at the opening, the circlip will be distorted and deformed, and in severe cases, it will directly burst open, which is not conducive to the stable operation of the equipment.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solution: A tapered roller bearing includes an outer bearing ring and an inner bearing ring. An anti - detachment component is arranged on the inner bearing ring, and the anti - detachment component is used to prevent the rollers from falling off. The anti - detachment component includes a circlip inclined groove, an open circlip, a threaded hole, a screw, a fixing plate, a connecting plate, a connecting column, and a catch.

[0008] The open circlip in the anti - detachment component is arranged between the small - diameter end of the inner bearing ring and the outer bearing ring. The open circlip is of an open - cone shape, which can better fix the outer bearing ring. The circlip inclined groove is opened at the small - diameter end of the inner bearing ring, and the open circlip is movably sleeved in the circlip inclined groove.

[0009] Preferably, a circlip outer top groove adapted to the edge of the open circlip is opened at the small - diameter end of the outer bearing ring. Both ends of the opening of the open circlip are provided with circlip holes for installation, and an installation groove is opened at the end face of the small - diameter of the inner bearing ring.

[0010] Preferably, the threaded hole is opened on the bottom wall of the installation groove. The fixing plate is sleeved on the outer surface of the screw, and the screw is threadedly connected to the threaded hole. The screw is used to fixedly install the fixing plate.

[0011] Preferably, the fixing plate is located in the installation groove, the connecting plate is fixedly connected to the fixing plate, and both connecting columns are fixedly connected to the side of the connecting plate close to the open circlip.

[0012] Preferably, the two connecting columns respectively extend into the corresponding circlip holes, and the two hooks are respectively fixedly connected to the ends of the corresponding connecting columns away from the connecting plate.

[0014] (III)Advantages

[0015] Compared with the prior art, the present utility model provides a tapered roller bearing, which has the following advantages:

[0016] 1. For this tapered roller bearing, by expanding the open circlip outward and sleeving it in the circlip inclined groove, and then releasing the circlip pliers, the open circlip will return to its original state and be stuck in the outer bearing ring in the circlip inclined groove. At this time, the outer edge of the open circlip will be adapted to the outer circlip top groove. When the outer bearing ring and the inner bearing ring are respectively subjected to staggered axial forces, the open circlip will be stuck between the circlip inclined groove and the outer circlip top groove. Since the open circlip is conical, the force between the outer bearing ring and the inner bearing ring can be better borne by the open circlip, which avoids the situation that in the traditional method, when using a flat circlip, under a large force, the circlip is laterally stressed, resulting in the circlip being distorted and directly popping open.

[0017] 2. For this tapered roller bearing, by inserting the two connecting columns on the connecting plate into the corresponding circlip holes, the hooks at this time will limit the opening of the open circlip, so that the open circlip cannot be opened. Then insert the screw into the fixing plate and install it in the threaded hole. At this time, the screw will fix the fixing plate and the connecting plate. Through the limitation of the opening of the open circlip by the connecting columns, the open circlip can bear the staggered axial forces more evenly, further avoiding the situation that the open circlip is expanded and the outer bearing ring and the inner bearing ring are separated and fall off.

Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0027] Please refer to Figures 1-4 , the present utility model provides a new technical solution: a tapered roller bearing, including an outer ring 1 of the bearing and an inner ring 2 of the bearing. An anti-detachment component is provided on the inner ring 2 of the bearing. The anti-detachment component is used to prevent the rollers from detaching. The anti-detachment component includes a snap ring inclined groove 3, a split snap ring 4, a threaded hole 8, a screw 9, a fixing plate 10, a connecting plate 11, a connecting column 12 and a hook 13;

[0028] The split circlip 4 in the anti-loosening component is arranged between the small-diameter end of the inner ring 2 of the bearing and the outer ring 1 of the bearing. The split circlip 4 is of a split conical shape, which can better fix the outer ring 1 of the bearing. The circlip groove 3 is opened at the small-diameter end of the inner ring 2 of the bearing, and the split circlip 4 is movably sleeved in the circlip groove 3.

[0029] Furthermore, a circlip outer top groove 5 adapted to the edge of the split circlip 4 is opened at the small-diameter end of the outer ring 1 of the bearing. Both ends of the opening of the split circlip 4 are provided with circlip holes 6 for installation. An installation groove 7 is opened at the end face of the small diameter of the inner ring 2 of the bearing.

[0030] Furthermore, a threaded hole 8 is opened at the bottom wall of the installation groove 7. The fixing plate 10 is sleeved on the outer surface of the screw 9. The screw 9 is threadedly connected to the threaded hole 8. The screw 9 is used to fixedly install the fixing plate 10.

[0031] Furthermore, the fixing plate 10 is located in the installation groove 7. The connecting plate 11 is fixedly connected to the fixing plate 10. Both connecting columns 12 are fixedly connected to the side of the connecting plate 11 close to the split circlip 4.

[0032] Furthermore, the two connecting columns 12 respectively extend into the corresponding circlip holes 6. Two hooks 13 are respectively fixedly connected to the ends of the corresponding connecting columns 12 away from the connecting plate 11.

[0033] Furthermore, the hook 13 is used to prevent the split circlip 4 from falling off. A plurality of bearing rollers 14 are arranged between the raceways of the outer ring 1 and the inner ring 2 of the bearing. A roller cage 15 is arranged between the plurality of bearing rollers 14.

[0034] Furthermore, during installation, the split circlip 4 is outwardly expanded and sleeved in the circlip groove 3 by using a circlip pliers inserted into the two circlip holes 6, and then the circlip pliers are released. At this time, the split circlip 4 will return to its original shape and be stuck in the outer ring 1 of the bearing in the circlip groove 3. At this time, the outer edge of the split circlip 4 will be adapted to the circlip outer top groove 5. When the outer ring 1 and the inner ring 2 of the bearing are respectively subjected to staggered axial forces, the split circlip 4 will be stuck between the circlip groove 3 and the circlip outer top groove 5. And because the split circlip 4 is conical, the force between the outer ring 1 and the inner ring 2 of the bearing can be better borne by the split circlip 4, which avoids the situation that in the traditional method of using a flat circlip, the circlip is laterally stressed under a large force, resulting in the circlip being distorted and directly popping open.

[0035] Furthermore, the two connecting columns 12 on the connecting plate 11 are inserted into the corresponding retaining spring holes 6. At this time, the hook 13 will limit the opening of the open retaining spring 4, so that the open retaining spring 4 cannot be opened. Then the screw 9 is inserted into the fixing plate 10 and installed in the threaded hole 8. At this time, the screw 9 will fix the fixing plate 10 and the connecting plate 11. The opening of the open retaining spring 4 is restricted by the connecting column 12, which enables the open retaining spring 4 to withstand the staggered axial force more evenly, further avoiding the open retaining spring 4 from being stretched open and the bearing outer ring 1 and the bearing inner ring 2 being separated and falling off.

[0036] Working principle: During installation, use circlip pliers to insert the two circlip holes 6, stretch the open circlip 4 outward and put it in the circlip bevel groove 3, and then release the circlip pliers. At this time, the open circlip 4 will return to its original state and be stuck in the bearing outer ring 1 in the circlip bevel groove 3. At this time, the outer ring edge of the open circlip 4 will be adapted to the outer top groove 5 of the circlip. When the bearing outer ring 1 and the bearing inner ring 2 are respectively subjected to staggered axial forces, the open circlip 4 will be stuck between the circlip bevel groove 3 and the outer top groove 5 of the circlip. Since the open circlip 4 is conical, the force between the bearing outer ring 1 and the bearing inner ring 2 can be better borne by the open circlip 4.

[0037] Furthermore, the two connecting columns 12 on the connecting plate 11 are inserted into the corresponding retaining spring holes 6. At this time, the hook 13 will limit the opening of the open retaining spring 4, so that the open retaining spring 4 cannot be opened. Then the screw 9 is inserted into the fixing plate 10 and installed in the threaded hole 8. At this time, the screw 9 will fix the fixing plate 10 and the connecting plate 11. The opening of the open retaining spring 4 is restricted by the connecting column 12, which enables the open retaining spring 4 to more evenly withstand the staggered axial force.
