Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a bearing with resistance to friction damage. Background Technology

[0002] Thin-walled bearings are a common type of mechanical part, widely used in industrial manufacturing and household appliances. They are characterized by a relatively large outer diameter and thin wall thickness, and can withstand radial and axial loads. The main structure of a thin-walled bearing includes an inner ring, an outer ring, and rolling elements.

[0003] In existing metal-structured bearings, the balls inside the bearing constantly rub against the thin wall of the bearing. Over time, the thin wall of the bearing is prone to damage, resulting in poor stability during operation. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by proposing a thin-walled bearing with an anti-friction damage structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a thin-walled bearing with an anti-friction damage structure, comprising an outer ring, an inner ring disposed inside the outer ring, and a plurality of balls disposed inside the outer ring, the plurality of balls being located between the outer ring and the inner ring. A lubrication device is provided on the arc surface of the outer ring, the lubrication device comprising a cavity, the cavity being opened inside the outer ring, a feed hole being provided on the outer ring via the cavity, a lubrication hole being provided on the outer ring via the cavity, the cavity being connected to the interior of the outer ring via the lubrication hole, and two mutually symmetrical pads fixedly connected to the cavity corresponding to the feed hole. A rotating rod is rotatably connected to one side of the two pads that are close to each other, and a common cover plate is fixedly connected to one end of the two rotating rods. The size of the cover plate is larger than the size of the feed hole.

[0006] The effect achieved by the above components is as follows: Before using the bearing, the operator first inserts the lubricating oil injection pipe into the feed hole. The lubricating oil injection pipe squeezes the cover plate, and the cover plate rotates along with the rotating rod, allowing the lubricating oil injection pipe to enter the cavity. Then, the operator injects lubricating oil into the cavity. When the bearing is in use, the inner and outer rings rotate, and the balls rotate inside. The lubricating oil in the cavity enters the outer ring through the lubrication hole and comes into contact with the balls, achieving the effect of lubricating the balls. The lubrication device achieves the effect of lubricating the balls, thereby reducing the friction between the balls and the outer and inner rings, and minimizing the risk of damage to the bearing due to prolonged use.

[0007] Preferably, the arc surface of the rotating rod is fitted with a coil spring, and the two ends of the coil spring are fixedly connected to the pad and the cover plate, respectively.

[0008] The effect achieved by the above components is as follows: when the lubricating oil injection pipe rotates with the cover plate, the coil spring deforms. When the lubricating oil injection pipe moves away from the cavity, the cover plate automatically covers the feed hole under the action of the coil spring's return force, preventing lubricating oil from flowing out of the feed hole.

[0009] Preferably, a sealing ring is fixedly connected to one side of the cover plate, and the size of the sealing ring is adapted to the size of the cover plate.

[0010] The effect achieved by the above components is that by setting a sealing ring, the gap between the cover plate and the cavity is sealed, preventing lubricating oil from flowing out of the gap.

[0011] Preferably, a guide plate is fixedly connected inside the cavity, and the guide plate is inclined toward the lubrication hole.

[0012] The effect achieved by the above components is that the guide plate guides the lubricating oil, making it easier for the lubricating oil to enter the interior of the outer ring through the lubrication hole.

[0013] Preferably, auxiliary devices are provided on both sides of the inner ring. The auxiliary devices include two protective plates, which are respectively located on both sides of the inner ring. Two mutually symmetrical mounting rods are fixedly connected to one side of each protective plate. Mounting holes are opened on the inner ring corresponding to the mounting rods. The size of the mounting holes is slightly larger than the size of the mounting rods. A rubber ring is fixedly connected to the arc surface of each mounting rod. A limiting groove is opened on the mounting hole corresponding to the rubber ring. The size of the rubber ring is adapted to the size of the limiting groove.

[0014] The effect achieved by the above components is as follows: When the bearing needs to be used, the operator first moves the protective plate, and the mounting rod on the protective plate is inserted into the mounting hole of the inner ring. The rubber ring on the mounting rod is deformed by the pressure of the inner wall of the mounting hole. When the rubber ring moves to the limiting groove position of the mounting hole, the rubber ring returns to its original shape and enters the limiting groove, thus achieving the effect of fixing the mounting rod and the protective plate. The protective plate installed by the auxiliary device achieves the effect of protecting the balls, preventing impurities from entering the interior of the outer and inner rings, thereby affecting the normal use of the bearing.

[0015] Preferably, one end of the mounting rod is fixedly connected to a pointed protrusion, the tip of which is away from the mounting rod.

[0016] The effect achieved by the above-mentioned components is that the pointed protrusions make it easier for workers to insert the mounting rod into the mounting hole of the inner ring, thus providing convenience for workers.

[0017] Preferably, two symmetrical grooves are fixedly connected to one side of the protective plate, and a pull plate is fixedly connected to the protective plate by means of the grooves.

[0018] The aforementioned components achieve the following effect: the pull plate in the groove facilitates the movement of the protective plate by the staff, thus providing convenience for the staff.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] Before using the bearing, the operator first inserts the lubricating oil injection pipe into the feed hole. The lubricating oil injection pipe presses against the cover plate, causing the cover plate to rotate along with the rotating rod, and the lubricating oil injection pipe enters the cavity. Then, the operator injects lubricating oil into the cavity. When the bearing is in use, the inner and outer rings rotate, and the balls rotate inside. The lubricating oil in the cavity enters the outer ring through the lubrication hole and comes into contact with the balls, achieving the effect of lubricating the balls. The lubrication device achieves the effect of lubricating the balls, thereby reducing the friction between the balls and the outer and inner rings, and minimizing the risk of damage to the bearing due to prolonged use.

Detailed Implementation

[0029] Reference Figure 1-7As shown, this embodiment discloses a thin-walled bearing with a friction-resistant structure, including an outer ring 1, an inner ring 2 inside the outer ring 1, a plurality of balls 3 inside the outer ring 1, the plurality of balls 3 being located between the outer ring 1 and the inner ring 2, a lubrication device 4 being provided on the arc surface of the outer ring 1, and auxiliary devices 5 being provided on both sides of the inner ring 2.

[0030] Reference Figure 1-7 As shown, the lubrication device 4 includes a cavity 41, which is located inside the outer ring 1. The outer ring 1 has a feed hole 42 through the cavity 41 and a lubrication hole 43 through the cavity 41. The cavity 41 is connected to the interior of the outer ring 1 through the lubrication hole 43. Two symmetrical pads 44 are fixedly connected to the cavity 41 corresponding to the feed hole 42. Rotating rods 45 are rotatably connected to the side of the two pads 44 that are close to each other. One end of the two rotating rods 45 is fixedly connected to the same cover plate 46. The size of the cover plate 46 is larger than the size of the feed hole 42. Before using the bearing, the operator first inserts the lubricating oil injection pipe into the feed hole 42. The lubricating oil injection pipe squeezes the cover plate 46, and the cover plate 46 rotates with the rotating rod 45. The lubricating oil injection pipe enters the cavity 41. Then, the operator injects lubricating oil into the cavity 41. When the bearing is in use, the inner ring 2 and the outer ring 1 rotate, and the balls 3 rotate inside. The lubricating oil in the cavity 41 enters the outer ring 1 through the lubrication hole 43 and comes into contact with the balls 3, thus achieving the effect of lubricating the balls 3. The lubrication device 4 achieves the effect of lubricating the balls 3, thereby reducing the friction between the balls 3 and the outer ring 1 and the inner ring 2, and minimizing the risk of damage to the bearing after prolonged use.

[0031] Reference Figure 1-7 As shown, a coil spring 47 is fitted onto the arc surface of the rotating rod 45, with its two ends fixedly connected to the pad 44 and the cover plate 46, respectively. When the lubricating oil injection pipe rotates with the cover plate 46, the coil spring 47 deforms. When the lubricating oil injection pipe moves away from the cavity 41, the cover plate 46 automatically covers the feed hole 42 under the restoring force of the coil spring 47, preventing lubricating oil from flowing out of the feed hole 42. A sealing ring 48 is fixedly connected to one side of the cover plate 46, and the size of the sealing ring 48 matches the size of the cover plate 46. By setting the sealing ring 48, the gap between the cover plate 46 and the cavity 41 is sealed, preventing lubricating oil from flowing out of the gap. A guide plate 49 is fixedly connected inside the cavity 41, and the guide plate 49 is inclined towards the lubrication hole 43. By setting the guide plate 49, the lubricating oil is guided, facilitating its entry into the outer ring 1 through the lubrication hole 43.

[0032] Reference Figure 1-7As shown, the auxiliary device 5 includes two protective plates 51, which are located on both sides of the inner ring 2. Two symmetrical mounting rods 52 are fixedly connected to one side of the protective plate 51. The inner ring 2 has mounting holes 53 corresponding to the mounting rods 52. The size of the mounting holes 53 is slightly larger than the size of the mounting rods 52. A rubber ring 54 is fixedly connected to the arc surface of the mounting rod 52. A limit groove is opened at the mounting hole 53 corresponding to the rubber ring 54. The size of the rubber ring 54 is adapted to the size of the limit groove. When the bearing needs to be used, the operator first moves the protective plate 51. The mounting rod 52 on the protective plate 51 is inserted into the mounting hole 53 of the inner ring 2. The rubber ring 54 on the mounting rod 52 is deformed by the pressure of the inner wall of the mounting hole 53. When the rubber ring 54 moves to the limiting groove position of the mounting hole 53, the rubber ring 54 returns to its original shape and enters the limiting groove, thus achieving the effect of fixing the mounting rod 52 and the protective plate 51. The protective plate 51 installed by the auxiliary device 5 achieves the effect of protecting the balls 3, preventing impurities from entering the interior of the outer ring 1 and the inner ring 2, thereby affecting the normal use of the bearing.

[0033] Reference Figure 1-7 As shown, a pointed protrusion 55 is fixedly connected to one end of the mounting rod 52, with the tip of the protrusion 55 away from the mounting rod 52. The pointed protrusion 55 facilitates the insertion of the mounting rod 52 into the mounting hole 53 of the inner ring 2, providing convenience for the operator. Two symmetrical grooves 56 are fixedly connected to one side of the protective plate 51, and a pull plate 57 is fixedly connected to the protective plate 51 via these grooves. The pull plate 57 in the grooves 56 facilitates the movement of the protective plate 51 by the operator, providing convenience for the operator.

[0034] Working principle: Before using the bearing, the operator first inserts the lubricating oil injection pipe into the feed hole 42. The lubricating oil injection pipe presses against the cover plate 46, causing the cover plate 46 to rotate along with the rotating rod 45. The coil spring 47 deforms, and the lubricating oil injection pipe enters the cavity 41. The operator then injects lubricating oil into the cavity 41. Finally, the operator pulls the lubricating oil injection pipe out of the cavity 41. Under the action of the return spring force of the coil spring 47, the cover plate 46 rotates towards the feed hole 42. Finally, the cover plate 46 covers the feed hole 42 with the help of the sealing ring 48. When the bearing is in use, the inner ring 2 and the outer ring 1 rotate, and the balls 3 rotate inside them. The lubricating oil in the cavity 41 enters the outer ring 1 through the guide plate 49 and the lubrication hole 43 and comes into contact with the balls 3, achieving the effect of lubricating the balls 3. The lubrication device 4 achieves the effect of lubricating the balls 3, thereby reducing the friction between the balls 3 and the outer ring 1 and the inner ring 2, and minimizing the risk of damage to the bearing after prolonged use.

[0035] When the bearing needs to be used, the operator first moves the protective plate 51 through the pull plate 57 in the groove 56. The mounting rod 52 on the protective plate 51 is inserted into the mounting hole 53 of the inner ring 2 by means of the pointed protrusion 55. The rubber ring 54 on the mounting rod 52 is deformed by the pressure of the inner wall of the mounting hole 53. When the rubber ring 54 moves to the limiting groove position of the mounting hole 53, the rubber ring 54 returns to its original shape and enters the limiting groove, thus achieving the effect of fixing the mounting rod 52 and the protective plate 51. The protective plate 51 installed by the auxiliary device 5 achieves the effect of protecting the ball 3, preventing impurities from entering the interior of the outer ring 1 and the inner ring 2, thereby affecting the normal use of the bearing.
