Description

Technical Field

[0001] The utility model relates to the technical field of bearing installation, in particular to a quick-disassembly, highly wear-resistant and self-lubricating bearing seat. Background Technique

[0002] Bearing installation refers to the process of correctly assembling a bearing into a mechanical device, ensuring its precise fit with components such as the shaft and bearing seat to achieve the functions of supporting rotating components, reducing friction, and transmitting loads. Bearing installation requires the use of a bearing seat. A self-lubricating bearing seat is a bearing support component that can operate stably for a long time without external lubricants and realizes the self-lubricating function through an internal solid lubricant material or a special structural design. Currently, most bearing seat materials on the market are good and have excellent wear resistance.

[0003] Currently, there are still certain deficiencies in the bearing seat. For example, traditional bearing seats are often difficult to disassemble, and the disassembly and assembly time is long.

[0004] In order to overcome the problem of inconvenient disassembly and replacement of bearings, a Chinese patent of the prior art (publication number: CN222254744U) discloses a quick-disassembly bearing seat. When disassembly is required, the worker only needs to use the operating structure to rotate the locking screw seat to loosen it, and then rotate the connecting screw rod to separate it from the opening card slot, so that the bearing cover can be opened, thus facilitating the replacement of the internal bearing. After the replacement is completed, the bearing cover and the bearing seat body can be locked and fixed by reverse operation.

[0005] However, there are still certain deficiencies in the currently used bearing seat. In the above document, the bearing seat opens the bearing cover by operating the screw rod to replace the bearing. This structure fixes the bearing in a rotational manner, and the force application points of the rotational operation are uneven. The bearing may have a slight force offset during use, thus affecting the service life of the bearing. Therefore, the existing structure needs to be improved. Content of the Utility Model

[0006] The purpose of the utility model is to provide a quick-disassembly, highly wear-resistant and self-lubricating bearing seat to solve the problem of inconvenient quick disassembly of the internal bearing of the bearing seat proposed in the above background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1. As Figures 1 - 5 shown in the technical solution, the present utility model provides the following technical solution: In order to solve the problem that the bearing seat is inconvenient for quickly disassembling the internal bearing, a rotating mechanism is disclosed:

[0031] It includes a bottom plate 1, on the top of the bottom plate 1, connecting seats 2 are symmetrically connected. On the upper surface of the connecting seat 2, a fixed cylinder 3 is fixed. On the surface of the fixed cylinder 3, an oil injection nozzle 4 is connected: On the surface of the fixed cylinder 3, a rotating cylinder 301 is connected. On the middle surface of the rotating cylinder 301, a worm gear 302 is installed. On the inner side of the rotating cylinder 301, T-shaped grooves 303 are symmetrically opened. Inside the rotating cylinder 301, a rotating mechanism for quick disassembly and assembly of the bearing is provided. The rotating mechanism includes a T-shaped ring 304. The T-shaped ring 304 runs through and rotates inside the T-shaped groove 303. The T-shaped ring 304 is fixed on the surface of the fixed cylinder 3. On the surface of the rotating cylinder 301, activity grooves 305 are symmetrically penetrated. Inside the activity grooves 305, extrusion grooves 306 are symmetrically opened. Inside the activity grooves 305 and the extrusion grooves 306, a sliding block 307 is movably connected through. The bottom end of the sliding block 307 is fixedly connected with an extrusion block 309. A through groove 308 is penetrated and opened at the top of the fixed cylinder 3. The through groove 308 and the extrusion groove 306 are both slidably connected with the sliding block 307. Multiple groups of extrusion blocks 309 are connected around the center of the fixed cylinder 3. On the surface of the bottom plate 1 close to the worm gear 302, an L-shaped block 318 is fixed. Inside the L-shaped block 318, a worm 319 is rotatably connected through. The bottom end of the worm 319 is installed on the upper surface of the bottom plate 1 through a bearing.

[0032] When the bearing seat is in use, a bearing needs to be installed inside the fixed cylinder 3, and the oil injection nozzle 4 can regularly lubricate the bearing, reducing bearing wear. The extrusion blocks 309 inside the fixed cylinder 3 will extrude and fix the bearing. When the bearing is damaged or fails and needs to be replaced, the worm 319 needs to be rotated first. The worm 319 can rotate through the L-shaped block 318 and the bearing on the upper surface of the bottom plate 1. When the worm 319 rotates, it can drive the worm gear 302 to engage and rotate. When the worm gear 302 engages and rotates, it can drive the rotating cylinder 301 to rotate. When the rotating cylinder 301 rotates, it can drive the T-shaped groove 303 to rotate. When the T-shaped groove 303 rotates, it can rotate through the T-shaped ring 304. When the rotating cylinder 301 rotates, it can drive the activity groove 305 and the extrusion groove 306 to rotate. When the extrusion groove 306 rotates, it can extrude both sides of the sliding block 307. After the sliding block 307 is extruded, it can slide outwards from the fixed cylinder 3 through the through groove 308. When the sliding block 307 slides, it can drive the extrusion block 309 to slide away from the bearing. As the extrusion block 309 slides, it no longer extrudes the inner bearing. After the bearing loses the extrusion of the extrusion block 309, it can be directly pushed out of the fixed cylinder 3 by hand or tools, thus realizing the quick disassembly of the bearing by the bearing seat and improving the convenience of using the bearing seat.

[0033] Embodiment 2, as Figure 2 、 Figure 6 and Figure 7For the technical solution shown, the present utility model provides the following technical solution: In order to solve the problem that it takes a relatively long time to replace the bearing seat after a failure occurs, a clamping mechanism is disclosed: positioning grooves 310 are symmetrically formed at the bottom of the connecting seat 2, and a clamping mechanism for improving the maintenance and replacement efficiency is provided at the bottom of the connecting seat 2. The clamping mechanism includes a connecting block 311, the connecting block 311 is fixed to the bottom of the connecting seat 2, symmetrically formed slots 313 are formed at the top of the bottom plate 1, a clamping groove 314 is formed through the side of the slot 313, the slot 313 is slidably connected to the connecting block 311, a telescopic groove 316 is formed on the side of the connecting block 311, a clamping block 317 is slidably connected through the inside of the telescopic groove 316, and a spring is connected between the clamping block 317 and the telescopic groove 316.

[0034] After the parts inside the fixed cylinder 3 are damaged, the clamping block 317 can be pressed. After the clamping block 317 is pressed, it can slide through the clamping groove 314 and the telescopic groove 316. When the clamping block 317 slides, it can squeeze the spring inside the telescopic groove 316. After the clamping block 317 is squeezed into the inside of the telescopic groove 316, the connecting seat 2 is pulled upward. When the connecting seat 2 is pulled, it can drive the positioning groove 310 and the connecting block 311 to move. When the positioning groove 310 moves, it can slide through the positioning block 312. When the connecting block 311 moves, it can slide through the slot 313. When the connecting block 311 and the positioning groove 310 slide to the designated position, the connecting seat 2 and the bottom plate 1 can be separated and disassembled. After the connecting seat 2 is disassembled, a new one can be replaced for use, and there is no need to disassemble the bottom plate 1 with threads, which further improves the convenience of using the bearing seat.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
