Description

Technical Field

[0001] This utility model belongs to the field of bearing testing technology, specifically a test device for the load-bearing capacity of a high-sealing double-row cylindrical roller bearing. Background Technology

[0002] As a core component of mechanical equipment, bearings directly determine the equipment's operational accuracy, reliability, and service life. Regardless of type, bearings—whether single-row, double-row, or tapered roller bearings—must undergo rigorous load-bearing capacity testing before leaving the factory or during use and maintenance to ensure their performance meets standards. Bearings come in various types and sizes. Testing requires fixing the bearing's inner ring, but testing devices typically use a single fixing method, which cannot quickly fix multiple types of bearings, resulting in poor versatility. Such bearing load-bearing capacity testing devices are inconvenient for fixing bearings of different sizes, making them impractical. Utility Model Content

[0027] Example

[0028] like Figure 1 As shown, this utility model proposes a test device for the load-bearing capacity of a high-sealing double-row cylindrical roller bearing, including a test base 1. A support plate 2 is connected to one side of the upper end of the test base 1. One end of the support plate 2 is connected to a transmission device body 3, which drives a circular plate 5 to rotate. A protective cover 4 is snapped onto one side of the lower part of the support plate 2. The protective cover 4 is sleeved on the outside of a circular rod 61 to protect the bearing under test. A circular plate 5 is rotatably connected to one end of the support plate 2. A limit component 6 is connected to one end of the circular plate 5. The limit component 6 includes a circular rod 61 installed on one side of the circular plate 5. A threaded groove 62 is opened on the outer side of the circular rod 61.

[0029] like Figure 2 and Figure 3 As shown, a partition plate 63 is connected to one side of the inner side of the round rod 61. A rotating rod 64 is connected to one end of the partition plate 63. Insertion slots 65 are provided around one end of the rotating rod 64. Gear discs 66 are fixedly sleeved on both sides of the outer side of the rotating rod 64. Gears 67 are meshed around the outer side of the gear discs 66. Support plates 68 are connected to both sides of the gears 67. One end of the support plate 68 is connected to one side of the inner side of the round rod 61.

[0030] Among them, a gear 67 is meshed with a toothed plate 69 on its outer side. The gear 67 and the toothed plate 69 mesh, and the gear 67 rotates under the drive of the gear disk 66, which in turn causes the gear 67 to move the toothed plate 69. One end of the toothed plate 69 extends through to the outside of the round rod 61 and is connected to an arc-shaped plate 617. Multiple arc-shaped plates 617 are fixed and limited by the toothed plate 69. The arc-shaped structure fits the inner side of the bearing better. The cross-section of the arc-shaped plate 617 is set with an arc-shaped structure. A rubber pad is set on the outside of the arc-shaped plate 617 to increase the friction and improve the fixing effect.

[0031] like Figure 4 As shown, a connecting plate 610 is connected to one end of the toothed plate 69. The connecting plate 610 is rotatably connected to the rotating rod 64. When the rotating rod 64 rotates, it will not drive the connecting plate 610 to rotate, so it will not affect the movement of the toothed plate 69. One end of the connecting plate 610 is rotatably connected to the rotating rod 64, and the other end of the connecting plate 610 extends through to the inside of the toothed plate 69 and is connected to a limiting plate 611. The limiting plate 611 limits the connecting plate 610 to prevent the toothed plate 69 from separating from the connecting plate 610.

[0032] like Figure 5 As shown, one end of the round rod 61 is connected to a pull rod 612, and one end of the pull rod 612 extends through into the interior of the round rod 61. A pressure plate 613 is rotatably sleeved on the outer side of the pull rod 612. The pull rod 612 and the rotating pressure plate 613 are rotatably connected. The rotation of the pull rod 612 will not cause the pressure plate 613 to rotate. Springs 614 are connected to all four sides of one end of the pressure plate 613.

[0033] Spring 614 applies elastic potential energy to pull rod 612. When it is necessary to connect rotating rod 64, pull rod 612 is moved. With the cooperation of plug block 616 and plug slot 65, rotating rod 64 is fixedly connected to pull rod 612, which facilitates the rotation of rotating rod 64. When it is not necessary to rotate rotating rod 64, pull rod 612 is released. Under the elastic potential energy of spring 614, pull rod 612 is driven to return to its original position. At this time, rotating rod 64 is in a fixed state. Therefore, with the cooperation of plug block 616 and plug slot 65, rotating rod 64 can be rotated according to usage requirements.

[0034] One end of the spring 614 is connected to one side of the inner wall of the round rod 61. One end of the pull rod 612 is provided with a fixing groove 615. All four sides of the fixing groove 615 are connected with plug blocks 616. The diameter of the plug blocks 616 is the same as the diameter of the plug groove 65. When the plug blocks 616 move into the plug groove 65, the pull rod 612 is fixed to the rotating rod 64. Rotating the pull rod 612 drives the rotating rod 64 to rotate.

[0035] like Figure 6 As shown, the protective cover 4 has snap-fit ​​grooves 7 on both sides of one end, and snap-fit ​​rods 8 are inserted into the snap-fit ​​grooves 7. When the protective cover 4 is not in use, the protective cover 4 is placed on the snap-fit ​​rods 8 for easy placement. One end of the snap-fit ​​rods 8 is connected to one side of the support plate 2. The inner side of the protective cover 4 is connected to a threaded sleeve 9, which contacts the round rod 61. By rotating the protective cover 4, the round rod 61 is threadedly connected and fixed to the protective cover 4 under the adaptation of the threaded sleeve 9 and the threaded groove 62, thereby protecting the test bearing with the protective cover 4. The inner diameter of the threaded sleeve 9 is the same as the outer diameter of the round rod 61.

[0036] The implementation principle of the load-bearing capacity testing device for a high-sealing double-row cylindrical roller bearing in this application embodiment is as follows: during use, the threaded sleeve 9 and the threaded groove 62 cooperate to make the protective cover 4 threadedly connected to the round rod 61 to protect the bearing under test.

[0037] The bearing to be tested is fitted onto the outside of the round rod 61. The pull rod 612 is pushed to one side, and the pull rod 612 drives the insertion block 616 to move into the insertion groove 65, so that the pull rod 612 is engaged with the rotating rod 64. The pull rod 612 is rotated, and the pull rod 612 drives the rotating rod 64 to rotate. The rotating rod 64 drives the gear plate 66 to rotate. Because the gear plate 66 meshes with the gear 67, and the gear 67 meshes with the gear plate 69, under the transmission action of the gear 67, the gear plate 69 drives the arc plate 617 to move in a straight line. Multiple arc plates 617 move outward, thereby limiting and fixing the bearing. This is suitable for fixing bearing bodies of different specifications and sizes. The pull rod 612 is released, and the pull rod 612 returns to its original position under the elastic potential energy of the spring 614, thereby fixing the rotating rod 64.

[0038] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
