Description

Technical Field

[0001] This utility model relates to the field of bearing end cap technology, specifically to an open bearing end cap structure for carton machinery accessories. Background Technology

[0002] In various transmission systems of carton machinery, bearings are the core components that support the rotation of shafts, and their stable operation is crucial to the performance of the entire equipment. In order to effectively protect and lubricate the bearings and to achieve their reliable positioning in the bearing housing, bearing end caps have become a widely used basic mechanical component.

[0003] According to CN217692893U, a motor bearing end cover structure is disclosed. This technology discloses a technical solution including "a motor end cover, a groove formed on the motor end cover, a fixed sleeve engaged in the groove, the fixed sleeve extending at least partially out of the groove and forming a first annular portion, a first annular contact portion formed on the inner wall of the fixed sleeve, a bearing engaged in the fixed sleeve, an internal thread structure formed on the inner wall of the opening of the fixed sleeve, an external thread structure formed on the outer wall of the rotating sleeve that mates with the internal thread structure, the rotating sleeve being twisted into the fixed sleeve to press the bearing onto the first annular contact portion, a second annular portion extending outward from the end of the rotating sleeve; a through groove formed on the second annular portion, a first screw hole formed on the second annular portion, a second screw hole formed on the surface of the motor end cover, and a locking screw passing through the through groove and the first screw hole in sequence and being twisted into the second screw hole." This solution has the technical effect of "solving the problem that existing motor housings are mostly integral structures with bearings fixed inside the housing, making them difficult to disassemble."

[0004] In the existing bearing end cover structure of carton machinery, fixed end covers that are axially tightened by multiple bolts are commonly used. This means that when it is necessary to inspect the bearing or replace the grease, all the mounting bolts must be unscrewed one by one using special tools to completely remove the end cover. This cumbersome disassembly process is not only time-consuming and labor-intensive, but also prone to damage to the end cover sealing surface and poor fit due to bolt stripping, corrosion, or uneven tightening torque during repeated disassembly and assembly. This allows dust and impurities to easily enter the bearing cavity, affecting the normal operating life of the bearing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an open bearing end cover structure for carton machinery accessories. The end cover can be quickly opened and closed with a single rotation operation, eliminating the need for disassembly for daily inspection, lubrication, and maintenance of the bearing, thus improving the convenience and efficiency of maintenance operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an open bearing end cover structure for a carton machinery component, comprising a carton machinery component, wherein the carton machinery component is provided with an open bearing end cover mechanism for positioning a shaft in the carton machinery component, the open bearing end cover mechanism comprising:

[0007] The load-bearing component includes a bearing housing fixed to a carton machinery accessory, with a first threaded hole at one end inside the bearing housing and four second threaded holes arranged circumferentially at the outer edge of the front end of the bearing housing.

[0008] The main component includes an annular seat located at the front end of the bearing housing. The bearing housing has six circumferentially arranged limiting grooves inside. The annular seat has six circumferentially arranged baffle heads inside. A circular slider is fixed to the rear end of the baffle head and located inside the limiting groove. A rectangular slider is fixed to the front end of the baffle head. An annular plate is rotatably installed at the front end inside the annular seat. A hexagonal guide groove is opened on the rear surface of the annular plate, and the rectangular slider is located inside the hexagonal guide groove. An extension head is fixed to one side of the outer end of the annular plate.

[0009] Preferably, the main body component further includes a knob bolt inserted through the extension head, and the knob bolt is threadedly mounted to the first threaded hole.

[0010] Preferably, the main component further includes a sealing ring installed between the rear end of the ring seat and the front end of the bearing seat.

[0011] Preferably, the main component further includes four mounting holes arranged circumferentially inside the ring seat.

[0012] Preferably, the main body component further includes a slot formed in the outer wall of the ring seat, and the extension head is located inside the slot.

[0013] Preferably, the outer wall of the baffle head is covered with a rubber sleeve made of elastic material for compression sealing when the baffle head is closed.

[0014] Beneficial effects

[0015] This utility model provides an open bearing end cover structure for a carton machinery component. Compared with the prior art, it has the following advantages:

[0016] 1. When the ring plate is rotated by turning the extension head, the hexagonal guide groove on its back rotates synchronously. Since the rectangular slider at the front end of each baffle head is embedded in this guide groove, and the circular slider at the rear end of each baffle head is constrained within the radial limiting groove of the bearing housing and can only slide radially, when the hexagonal guide groove rotates, its inner inclined surface interacts with the rectangular slider, forcing the circular motion of the ring plate into the synchronous radial linear motion of the rectangular slider and the baffle head fixed thereto along the limiting groove. When it is necessary to check the bearing condition inside the bearing housing, replace the grease, or deal with abnormal noise, rotating the ring plate counterclockwise will drive the baffle head to open radially outward, forming a window for easy observation and operation; after maintenance is completed, rotating the ring plate clockwise will drive the baffle head to close radially inward, restoring the sealed protection of the bearing.

[0017] 2. When the baffle head is in the closed state, the ring plate can be fixed and the baffle head locked by inserting the knob bolt through the extension head and screwing it into the first threaded hole on the bearing seat. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an open bearing end cover structure for a carton machinery component, including a carton machinery component 1, an open bearing end cover mechanism 2 provided on the carton machinery component 1 for positioning the shaft in the carton machinery component 1, the open bearing end cover mechanism 2 including:

[0025] The bearing assembly 21 includes a bearing seat 211 fixed on the carton machinery accessory 1. One end of the bearing seat 211 has a first threaded hole 212, and the outer edge of the front end of the bearing seat 211 has four circumferentially arranged second threaded holes 213.

[0026] The main component 22 includes an annular seat 221 disposed at the front end of the bearing housing 211. The bearing housing 211 has six circumferentially arranged limiting grooves 222 inside. The annular seat 221 has six circumferentially arranged baffle heads 223 inside. A circular slider 224 is fixed to the rear end of the baffle head 223 and is located inside the limiting groove 222. A rectangular slider 225 is fixed to the front end of the baffle head 223. An annular plate 226 is rotatably mounted at the front end inside the annular seat 221. A hexagonal guide groove 227 is disposed on the rear surface of the annular plate 226, and the rectangular slider 225 is located inside the hexagonal guide groove 227. An extension head 228 is fixed to one side of the outer end of the annular plate 226.

[0027] In this embodiment, when the ring plate 226 is rotated by turning the extension head 228, the hexagonal guide groove 227 on its back side rotates synchronously. Since the rectangular slider 225 at the front end of each baffle head 223 is embedded in the guide groove, and the circular slider 224 at the rear end of each baffle head 223 is constrained in the radial limiting groove 222 of the bearing seat 211 and can only slide radially, when the hexagonal guide groove 227 rotates, its inner inclined surface interacts with the rectangular slider 225, forcing the circular motion of the ring plate 226 into the synchronous radial linear motion of the rectangular slider 225 and the baffle head 223 fixed thereto along the limiting groove 222. When it is necessary to check the bearing condition inside the bearing housing 211, replace the grease, or deal with abnormal noises, rotating the ring plate 226 counterclockwise will drive the baffle head 223 to open radially outward, forming a window that is easy to observe and operate; after the maintenance operation is completed, rotating the ring plate 226 clockwise will drive the baffle head 223 to close radially inward, restoring the sealed protection state of the bearing.

[0028] Specifically, the main body component 22 also includes a knob bolt 229 that is inserted through the extension head 228 and is threadedly mounted to the first threaded hole 212.

[0029] In this embodiment, when the baffle head 223 is in the closed state, the ring plate 226 can be fixed and the baffle head 223 can be locked by inserting the knob bolt 229 through the extension head 228 and screwing it into the first threaded hole 212 on the bearing seat 211.

[0030] Specifically, the main component 22 also includes a sealing ring 2210 installed between the rear end of the ring seat 221 and the front end of the bearing seat 211.

[0031] In this embodiment, when the ring seat 221 is fixed on the bearing seat 211, the sealing ring 2210 is tightly pressed between the joint end faces of the two components to seal.

[0032] Specifically, the main component 22 also includes four mounting holes 2211 arranged circumferentially inside the ring seat 221.

[0033] In this embodiment, the ring seat 221 is fitted with bolts through four mounting holes 2211 arranged on its inner circumference, and is aligned with and threadedly fastened to the second threaded hole 213 corresponding to the outer edge of the bearing seat 211 of the bearing assembly 21, thereby stably installing the entire main body assembly 22 on the bearing assembly 21.

[0034] Specifically, the main body component 22 also includes a slot 2212 formed on the outer wall of the ring seat 221, and the extension head 228 is located inside the slot 2212.

[0035] In this embodiment, the slot 2212 provides a limited space for the rotation of the extension head 228.

[0036] Specifically, the outer wall of the baffle head 223 is covered with a rubber sleeve made of elastic material, which is used for compression sealing when the baffle head 223 is closed.

[0037] In this embodiment, when all baffle heads 223 are in a radially inward closed state, the rubber sleeve sides on adjacent baffle heads 223 are tightly pressed against each other and undergo elastic deformation, thereby forming a seal at the joints of all baffle heads 223 and improving the sealing performance of the bearing housing 211.

[0038] The working principle and usage process of this utility model are as follows: First, when the ring plate 226 is rotated by moving the extension head 228, the hexagonal guide groove 227 on its back side rotates synchronously. Since the rectangular slider 225 at the front end of each baffle head 223 is embedded in the guide groove, and the circular slider 224 at the rear end of each baffle head 223 is constrained in the radial limiting groove 222 of the bearing seat 211 and can only slide radially, when the hexagonal guide groove 227 rotates, its inner inclined surface interacts with the rectangular slider 225, forcing the circular motion of the ring plate 226 into the synchronous radial linear motion of the rectangular slider 225 and the baffle head 223 fixed thereto along the limiting groove 222. When it is necessary to check the bearing condition inside the bearing housing 211, replace the grease, or deal with abnormal noises, rotating the ring plate 226 counterclockwise will drive the baffle head 223 to open radially outward, forming a window for easy observation and operation. After maintenance is completed, rotating the ring plate 226 clockwise will drive the baffle head 223 to close radially inward, restoring the sealed protection of the bearing. When the baffle head 223 is closed, the ring plate 226 can be fixed and the baffle head 223 locked by inserting the knob bolt 229 through the extension head 228 and screwing it into the first threaded hole 212 on the bearing housing 211.
