Description

Technical Field

[0001] The utility model relates to the technical field of bearing end covers, in particular to a bearing end cover. Background Art

[0002] Bearings are an important component in mechanical equipment. They are mainly composed of inner rings, outer rings, and rolling elements. They can support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings are widely used in various fields, such as metallurgy, wind power, mining machinery, aerospace, and automobile manufacturing, and are essential for improving the performance and reliability of mechanical equipment.

[0003] When the bearing is installed, a bearing end cover is used to fix and seal the bearing. It is usually installed on the outside of the bearing to prevent dust and impurities from entering the bearing. At the same time, the bearing end cover also helps to keep the position of the bearing stable. The convex ring on the inner side of the current bearing end cover contacts the outer ring of the bearing after installation. Due to the vibration during operation, the contact part between the convex ring and the outer ring of the bearing is prone to wear, resulting in reduced performance. The current bearing end cover is mostly an integrated fixed structure, which is not easy to detect after wear. The entire bearing end cover needs to be disassembled for maintenance, which is not convenient. If it is replaced after wear, it needs to be replaced as a whole, and the replacement cost is high. Therefore, those skilled in the art provide a bearing end cover to solve the problems raised in the above background technology. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Please see attached Figures 1 to 4 As shown, a bearing end cover in an embodiment of the utility model includes an end cover body 1, an inspection cover 2 and an inner ring 5. The end cover body 1 includes a main ring body 11. A matching groove 14 is opened on the inner side of the lower end surface of the main ring body 11. A plurality of first connecting holes 13 are evenly spaced on the inner side of the matching groove 14. The matching groove 14 is an annular groove for connecting the inner ring 5.

[0029] The inner ring 5 includes a convex ring 52, and a matching ring 51 is fixedly connected to the lower end of the outer side of the convex ring 52. The matching ring 51 is clamped with the matching groove 14. A plurality of second connecting holes 54 are evenly spaced apart on the outer end of the matching ring 51. The second connecting holes 54 correspond to the first connecting holes 13 one by one and are connected with screws 4. The provided convex ring 52 abuts against the outer ring of the bearing after being installed with the bearing, thereby stabilizing the bearing and improving the stability of the bearing after installation. When the convex ring 52 is installed, the first connecting hole 13 and the second connecting hole 54 are aligned, so that the matching ring 51 is installed in the matching groove 14, and then screws 4 are set inside each of the first connecting hole 13 and the second connecting hole 54, so as to connect and fix the inner ring 5 to the end cover body 1. The detachable inner ring 5 allows the inner ring 5 to be removed and replaced alone after the convex ring 52 of the inner ring 5 is worn, without replacing the entire bearing end cover, which can effectively reduce the cost of use.

[0030] The inspection cover 2 includes an outer plate 21, which is covered on the upper end surface of the main ring body 11. The inner side of the main ring body 11 is fixedly connected with an inner screw sleeve 15, and the inner side of the lower end surface of the outer plate 21 is fixedly connected with an outer screw sleeve 23. The outer screw sleeve 23 is sleeved with the inner screw sleeve 15, and the upper end surface of the outer plate 21 is fixedly connected with a hexagonal head 22. The inspection cover 2 is connected and fixed to the inner screw sleeve 15 on the inner side of the main ring body 11 through the outer screw sleeve 23. When disassembling, the hexagonal head 22 can be rotated by a tool to disassemble it. The detachable inspection cover 2 can expose the internal space of the end cover body 1 without disassembling the end cover body 1, which is convenient for observing the working condition of the bearing and the degree of wear of the inner ring 5, and is more convenient during maintenance.

[0031] One end of the screw 4 is sleeved with a connecting sleeve 3, and the connecting sleeve 3 is arranged on the inner side of the outer end of the first connecting hole 13. The connecting sleeve 3 includes a threaded sleeve 32, and the threaded sleeve 32 is sleeved with the screw 4. The outer end of the threaded sleeve 32 is fixedly connected with a screwing head 31. The connecting sleeve 3 is provided to improve the stability of the screw 4. After the screw 4 is installed, the threaded sleeve 32 of the connecting sleeve 3 is sleeved on the end of the screw 4, and then the screwing head 31 is rotated by a tool to tightly sleeve the threaded sleeve 32 and the screw 4. The connecting sleeve 3 is located at the outer end of the end cover body 1. After the end cover body 1 is installed, it can be easily checked whether it is loose, and it is convenient and quick to use.

[0032] A first sealing ring 24 is fixedly connected to the lower end surface of the outer plate 21 near the periphery, and the first sealing ring 24 contacts the surface of the main ring body 11. A second sealing ring 53 is fixedly connected to the end of the convex ring 52 away from the matching ring 51. The first sealing ring 24 can improve the sealing between the outer plate 21 and the main ring body 11 after the inspection cover 2 is installed, improve the sealing effect, prevent dust from entering, and enhance reliability. The second sealing ring 53 is used to improve the sealing between the convex ring 52 and the outer ring of the bearing.

[0033] A plurality of mounting holes 12 are evenly spaced apart on the periphery of the main ring body 11 , and the mounting holes 12 are used to connect and fix the main ring body 11 to the mounting surface.

[0034] A plurality of positioning posts 55 are fixedly connected to the upper end surface of the mating ring 51, and a plurality of positioning holes 16 are opened at the bottom of the mating groove 14. The positioning posts 55 are plugged into the positioning holes 16 one by one. When the mating ring 51 is inserted into the mating groove 14, the positioning posts 55 and the positioning holes 16 can be aligned first, and the positioning posts 55 can be passed into the positioning holes 16, thereby ensuring that after the mating ring 51 is installed in the mating groove 14, the first connecting hole 13 can be aligned with the second connecting hole 54.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
