Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0017] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0018] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0019] In the description of the utility model, it needs to explain that, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the utility model product is used, or the orientation or positional relationship commonly understood by those skilled in the art, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second" and the like are only used for differentiation in description and cannot be understood as indicating or implying relative importance.

[0020] In the description of the utility model, it also needs to explain that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0021] Reference Figures 1-3 An embodiment of the utility model is shown in the drawings as follows:

[0022] A kind of wear-resistant carrier roller, including carrier roller shaft 1, the carrier roller shaft 1 is rotatably installed with support cylinder 3 by bearing 2, support cylinder 3 is equipped with wear-resistant bushing 4, both ends of support cylinder 3 are installed with end cap plate 6 by countersunk head screw 5, the outer diameter of end cap plate 6 is less than the outer diameter of support cylinder 3, and the relative installation of end cap plate 6 and support cylinder 3 is equipped with the packaging piece of wear-resistant bushing 4.

[0023] Specifically, the packaging piece includes half circular ring sheet 7, the width of half circular ring sheet 7 is the sum of the wall thickness of support cylinder 3 and the wall thickness of wear-resistant bushing 4, and the inner ring of half circular ring sheet 7 is provided with through slot hole 8 adapted to the countersunk head screw, and the outer side of half circular ring sheet 7 is integrally formed with abutting ring 9 adapted to end cap plate 6.

[0024] The bending strength of the carrier roller is guaranteed by the support cylinder, the wear-resistant bushing 4 on the outer side improves the wear resistance of the carrier roller, prolongs the service life of the carrier roller, and the wear-resistant bushing 4 can be made of high molecular wear-resistant material to avoid excessive overall quality. After serious wear, the wear-resistant bushing 4 on the outer side can be replaced individually without the need for overall replacement, thereby reducing costs.

[0025] The packing is set, when maintaining and replacing, the countersunk screw on the side of the carrier roller is appropriately loosened, then the packing is pulled out and taken off, so that the wear-resistant bush 4 is conveniently taken off alone and a new wear-resistant bush 4 is replaced. Since the countersunk screw does not need to be completely disassembled when being replaced, after the wear-resistant bush 4 is assembled and the packing is inserted again, the countersunk screw is locked again, the problem of many assembly procedures after complete disassembly is avoided, and the maintenance and replacement are more convenient. In order to facilitate the insertion of the packing, as shown in Figure 3 The size specifications of the through slot holes 8 are not consistent.

[0026] After assembly, the abutting ring 9 of the packing is in contact with the outer edge of the end cover plate 6, so that the clamping of the semicircular ring piece 7 on the wear-resistant bush 4 is ensured.

[0027] Further, the outer side of the abutting ring 4 is coplanar with the outer side of the end cover plate 6, and the semicircular ring piece 7 is provided with a friction strip 10 between the abutting ring 9 and the through slot hole 8. The friction strip 10 is arranged to increase the friction force of the contact surface, so that the countersunk screw is not easy to slide when subjected to external force, and plays a role of preventing loosening.

[0028] In the embodiment, the inner side of the semicircular ring piece 7 is provided with a positioning protrusion 11, and the end of the wear-resistant bush 4 is provided with a groove matched with the positioning protrusion 11.

[0029] The positioning protrusion 11 is integrally formed with the semicircular ring piece 7, and the outer edge of the positioning protrusion 11 is provided with an arc surface 12 matched with the wear-resistant bush 4.

[0030] The positioning protrusion 11 is arranged to position the wear-resistant bush 4, improve stability, further prevent relative rotation between the wear-resistant bush 4 and the supporting cylinder 3, and effectively reduce operating noise.

[0031] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
