Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a deep groove ball bearing with self-lubricating grooves. Background Technology

[0002] Deep groove ball bearings, as one of the most widely used basic components in the machinery industry, are widely used in motors, machine tools, automobiles, home appliances, and general machinery equipment due to their simple structure, stable operation, and balanced load-bearing capacity. Their operational reliability directly affects the working efficiency and service life of the entire machine. With the increasing demand for industrial automation, lightweight equipment, and long-cycle operation, the market has placed higher requirements on the ease of lubrication and maintenance, as well as the shock resistance of deep groove ball bearings. This is especially true in continuous production lines or equipment scenarios where disassembly and maintenance are difficult, where bearing maintenance efficiency and durability become key considerations.

[0003] Existing deep groove ball bearings typically employ either fixed sealing or periodic disassembly for lubrication. Fixed-seal bearings require complete replacement after grease depletion, increasing maintenance costs and disrupting production schedules due to downtime. While removable lubrication bearings allow for lubrication replenishment, the lack of precise lubrication control mechanisms makes them prone to excessive oil leakage or uneven lubrication due to internal pressure imbalances, thus affecting bearing accuracy. Furthermore, existing bearing protection structures are often integrated and fixed designs. To accommodate installation requirements, the edges of the protective cover are typically thin, making them susceptible to deformation and damage from equipment vibrations or minor external impacts. While thickening the protective cover can improve protection, it increases installation difficulty, making it challenging to balance effective protection with installation compatibility.

[0004] In response to this technical problem, this application proposes a deep groove ball bearing with self-lubricating grooves. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deep groove ball bearing with self-lubricating grooves. The bearing is controlled by a button, which drives an auxiliary shaft to move a movable plate, enabling convenient opening and closing of the double oil grooves while balancing lubrication and air pressure. A rotating ring drives a sliding block for extension and retraction protection, which, combined with a rubber pad for shock absorption, enhances both lubrication and maintenance convenience and impact resistance stability, making it suitable for demanding operating conditions such as long service cycles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A deep groove ball bearing with self-lubricating grooves includes a rotating shaft and a bearing seat. An inner ring raceway is fixedly connected to the outer wall of the rotating shaft. A protective cover is fixedly connected to the outer wall of the inner ring raceway. A positioning frame is rotatably connected between the two protective covers. Steel balls are disposed inside the positioning frame. An oil groove is formed on the front outer wall of the protective cover. A control component is disposed inside the middle of the protective cover. A protective component is disposed on the front side of the outer wall of the protective cover. An outer ring raceway is rotatably connected to the outer wall of the protective cover. The outer wall of the outer ring raceway is fixedly connected to the inside of the bearing seat.

[0007] Furthermore, the control component includes an auxiliary shaft slidably connected inside the protective cover, a fixed shaft fixedly connected inside the right side of the auxiliary shaft, a button fixedly connected to the right end of the fixed shaft, and the outer wall of the button being disposed on the outer side of the outer wall of the protective cover.

[0008] Furthermore, the protective component includes a fixing ring fixedly connected to the front side of the protective cover, the fixing ring having a thread on its left outer wall, and a sliding block slidably connected inside the fixing ring.

[0009] Furthermore, a limit rod is provided inside the left side of the auxiliary shaft, a spring is sleeved on the outer left side of the limit rod, and a protrusion is fixedly connected to the outer right side of the limit rod.

[0010] Furthermore, the outer wall of the auxiliary shaft is provided with an elongated guide groove and a short guide groove, and the elongated guide groove and the short guide groove are arranged alternately on the surface of the auxiliary shaft.

[0011] Furthermore, a movable plate is fixedly connected to the outer wall of the left side of the auxiliary shaft, and the outer wall of the movable plate is disposed on the outer wall of the left side of the oil tanks on both sides.

[0012] Furthermore, a rotating ring is provided on the left outer wall of the fixed ring, and a guide groove is provided on the outer wall of the rotating ring. The outer wall of the rotating ring is threadedly connected to the left side of the outer wall of the fixed ring.

[0013] Furthermore, a connecting rod is fixedly connected to the left end of the sliding block, and the outer wall of the connecting rod is disposed inside the guide groove.

[0014] This utility model has the following beneficial effects: 1. In this utility model, pressing the button pushes the fixed shaft to slide to the left, releasing the constraint on the auxiliary shaft. The auxiliary shaft and the limit rod mesh with each other, causing the protrusion to rotate. After releasing the button, the spring drives the auxiliary shaft to rebound, and the protrusion engages with guide grooves of different heights, causing the auxiliary shaft to extend and retract. The auxiliary shaft drives the movable plate to move. When it shortens, the movable plate moves to the left, revealing a double oil groove. One groove is specifically for injecting lubricating oil, while the other simultaneously balances the internal air pressure, preventing excessive air pressure during oiling that could lead to leakage or uneven lubrication. This ensures that the lubricating oil is accurately supplied to the core rolling parts, making maintenance convenient and efficient.

[0015] 2. In this utility model, the problem of the large area of ​​the protective cover being easily damaged is addressed by rotating the rotating ring with its left threaded connection. When the rotating ring's guide groove is rotated, the sliding block inside the fixed ring is driven out through the connecting rod, providing support and reinforcement to the edge of the protective cover. The threaded connection ensures the stability of the protective structure, the rubber pad at the connection point buffers operational vibrations, and the telescopic design of the sliding block balances protective effect with ease of installation, avoiding structural interference during installation and significantly improving the bearing's impact resistance and service life.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Reference Figure 2 , Figure 3 and Figure 5This utility model provides an embodiment of a deep groove ball bearing with self-lubricating grooves, comprising a rotating shaft 1 and a bearing seat 3. An inner ring raceway 2 is fixedly connected to the outer wall of the rotating shaft 1. A protective cover 18 is fixedly connected to the outer wall of the inner ring raceway 2. A positioning frame 4 is rotatably connected between the two protective covers 18. Steel balls 7 are disposed inside the positioning frame 4. An oil groove 12 is formed on the front outer wall of the protective cover 18. An auxiliary shaft 13 is disposed inside the middle of the protective cover 18. A fixed shaft 14 is fixedly connected to the right side of the auxiliary shaft 13. A button 8 is fixedly connected to the right end of the fixed shaft 14. The outer wall of the button 8 is disposed on the outer side of the outer wall of the protective cover 18. A fixing ring 5 is disposed on the front side of the outer wall of the protective cover 18. A thread is provided on the left outer wall of the fixing ring 5. A sliding block 15 is slidably connected inside the fixing ring 5. An outer ring raceway 6 is rotatably connected to the outer wall of the protective cover 18. The outer wall of the outer ring raceway 6 is fixedly connected inside the bearing seat 3.

[0020] Specifically, pressing button 8 causes the lower fixed shaft 14 to slide to the left, thereby causing the auxiliary shaft 13 to move downward. After the lower protrusion is released from the constraint of the fixed shaft 14, the meshing of the auxiliary shaft 13 and the limiting rod 11 causes the protrusion to rotate slightly. When the button is released, the auxiliary shaft 13 rebounds upward under the force of the spring 9. Because of the slight rotation, the inclined groove on the side of the limiting rod 11 rotates along the edge of the long or short guide groove on the right side, thus getting stuck inside the long or short guide groove. Because the opening height of the long and short guide grooves is different, the extension and retraction of the protrusion lifting the auxiliary shaft 13 are different. When the auxiliary shaft 13 extends, it will drive the movable plate 10 to move to the right, thereby covering the two oil grooves 12 at the same time. When it shortens, it will drive the movable plate 10 to move to the left, thereby exposing the two oil grooves 12. One is used to add lubricating oil, and the other is used to adjust the air pressure inside the device to maintain the stability inside the device. Because the bearing components are mounted, and because the protective cover 18 has a large area and connects two parts, the upper part is easily damaged by impact. After installing the protective cover 18, rotating the rotating ring 16 drives the internal guide groove 17 to rotate, thereby causing the internal sliding block 15 to slide out from inside the fixed ring 5. This does not affect the installation of the device, and can also provide minor protection for the edge of the protective cover 18. The rotating ring 16 is threaded to the left side surface of the fixed ring 5, and the threaded connection maintains the stability of the device. A rubber pad is placed at the connection to prevent vibration from affecting the device.

[0021] Reference Figure 1 Figure 4 and Figure 5A limiting rod 11 is provided inside the left side of the auxiliary shaft 13. A spring 9 is sleeved on the outer left side of the limiting rod 11, and a protrusion is fixedly connected to the outer right side of the limiting rod 11. The outer wall of the auxiliary shaft 13 has both long and short guide grooves, which are arranged alternately on the surface of the auxiliary shaft 13. A movable plate 10 is fixedly connected to the outer left side of the auxiliary shaft 13, and its outer wall is located on the outer left side of the two oil grooves 12. A rotating ring 16 is provided on the outer left side of the fixed ring 5, and its outer wall has a guide groove 17. The outer wall of the rotating ring 16 is threadedly connected to the left side of the outer wall of the fixed ring 5. A connecting rod is fixedly connected to the left end of the sliding block 15, and its outer wall is located inside the guide groove 17.

[0022] Specifically, one embodiment of this utility model provides a deep groove ball bearing with self-lubricating grooves, including a rotating shaft 1 and a bearing seat 3. An inner ring raceway 2 is fixedly connected to the outer wall of the rotating shaft 1. A protective cover 18 is fixedly connected to the outer wall of the inner ring raceway 2. A positioning frame 4 is rotatably connected between the two protective covers 18. Steel balls 7 are disposed inside the positioning frame 4. An oil groove 12 is formed on the front outer wall of the protective cover 18. An auxiliary shaft 13 is disposed inside the middle of the protective cover 18. A fixed shaft 14 is fixedly connected to the right side of the auxiliary shaft 13. A button 8 is fixedly connected to the right end of the fixed shaft 14. The outer wall of the button 8 is located on the outer side of the outer wall of the protective cover 18. A fixing ring 5 is disposed on the front side of the outer wall of the protective cover 18. A thread is provided on the left outer wall of the fixing ring 5. A sliding block 15 is slidably connected inside the fixing ring 5. An outer ring raceway 6 is rotatably connected to the outer wall of the protective cover 18. The outer wall of the outer ring raceway 6 is fixedly connected inside the bearing seat 3.

[0023] A limiting rod 11 is located inside the left side of the auxiliary shaft 13. A spring 9 fitted on its left side provides a reset force, and a fixed protrusion on the right side is the core limiting component. Long and short guide grooves are arranged alternately on the outer wall of the auxiliary shaft 13, providing different height engagement positions for the protrusion. This, combined with the spring 9, enables the auxiliary shaft 13 to extend and retract for positioning. A movable plate 10 fixed to the left side of the auxiliary shaft 13 fits against the left side of the oil groove 12, precisely controlling the opening and closing of the oil groove 12 as the auxiliary shaft 13 extends and retracts. The guide groove 17 on the outer wall of the fixed ring 5 cooperates with the connecting rod at the left end of the sliding block 15. When the rotating ring 16 is rotated, the guide groove 17 drives the sliding block 15 to slide out of the fixed ring 5, providing support and protection for the edge of the protective cover 18, preventing it from being damaged by impact. Threaded connections ensure the stable fixing of the rotating ring 16, and rubber pads at the connection points buffer vibrations. The telescopic design of the sliding block 15 balances protection and ease of installation. The overall structure enhances lubrication control precision and protective stability.

[0024] Working principle: Pressing button 8 pushes the fixed shaft 14 to the left, releasing the constraint on the auxiliary shaft 13. The meshing teeth between the auxiliary shaft 13 and the limit rod 11 cause the protrusion to rotate slightly. After releasing the button, the spring 9 causes the auxiliary shaft 13 to rebound, and the protrusion engages in either the long or short guide groove at different heights, allowing the auxiliary shaft 13 to extend or retract in different states. When the auxiliary shaft 13 extends or retracts, it causes the movable plate 10 fixed on the left to move: when extended, the movable plate 10 moves to the right, blocking the two oil grooves 12; when shortened, it moves to the left, exposing the oil grooves 12. One of the oil grooves 12 is used to add lubricating oil, and the other balances the internal air pressure.

[0025] When rotating the rotating ring 16, its guide groove 17 drives the sliding block 15 in the fixed ring 5 to slide out through the connecting rod, forming a support and protection for the edge of the protective cover 18; the threaded connection ensures the stability of the rotating ring 16, and the rubber pad at the connection buffers the vibration, improving the impact resistance without affecting the installation of the device.

[0026] The circuits, protection, and bearing technologies involved in the above embodiments are all based on the actual situation and adopt the corresponding existing technologies. Therefore, they will not be described in detail in the embodiments of this application.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
