Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a bearing testing device. Background Technology

[0002] Existing bearing testing equipment has many problems in practical use. Traditional equipment mostly adopts a single clamping method, which only fixes the inner or outer ring of the bearing. It lacks dual positioning constraints, which makes it easy for the bearing to rotate and cause axial displacement and radial wobble, making it difficult to maintain a stable posture. Moreover, the clamping structure is mostly of fixed specifications, which is difficult to adapt to bearings with different inner and outer diameters. Frequent clamping changes are required, which is troublesome and significantly reduces testing efficiency. Utility Model Content

[0003] To address the aforementioned problems (...the problems), this application provides a bearing testing device.

[0004] The bearing testing equipment provided in this application adopts the following technical solution:

[0005] A bearing testing device includes a base, with a support foot fixedly connected to the bottom of the base, a rotating disk rotatably connected to the top of the base, a connecting frame fixedly connected to the back of the base, a fixed seat fixedly connected to the bottom of the connecting frame, a fixed seat fixedly connected to the bottom of the fixed seat, a motor fixedly connected to the top of the fixed seat, a first gear fixedly connected to the output end of the motor, a second gear meshing with the tooth end of the first gear, a plurality of rotating grooves provided on the surface of the second gear, an adjusting bolt provided inside the rotating grooves, a movable block fixedly connected to the top of the adjusting bolt, and a fixed clamping block fixedly connected to one end of the movable block.

[0006] Preferably, the bottom of the fixed base is provided with multiple sliding grooves, and the movable block is located inside the sliding grooves.

[0007] Preferably, a plurality of cylinders are fixedly connected to the top of the rotating disk, a telescopic rod is movably connected to one end of each cylinder, a clamping plate is fixedly connected to one end of the telescopic rod, and a placement plate is fixedly connected to the bottom of the clamping plate.

[0008] Preferably, the rotating disk is horizontally positioned at the top center of the base, and the axis of the rotating disk coincides with the vertical center line of the base.

[0009] Preferably, both the first gear and the second gear are located in the area below the fixed base, and the first gear and the second gear are parallel to each other.

[0010] Preferably, the clamping plate is horizontally connected to the output end of the cylinder via a telescopic rod, and the clamping plate is located above the placement plate.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. The cylinder drives the telescopic rod to move the clamping plate horizontally. Together with the support of the placement plate for the bottom of the bearing, it can stably clamp the outer ring of bearings of different sizes. The clamping force acts in the horizontal direction to prevent the bearing from shifting. At the same time, the rotating disk rotates smoothly around the center of the base, causing the clamped bearing to rotate synchronously. This allows the testing components to fully contact the outer ring of the bearing, ensuring that the bearing position is stable and the rotation is smooth during the testing process, thus improving the comprehensiveness of the testing.

[0013] 2. The mating structure of the clamping plate and the placement plate is adapted to the clamping requirements of various bearing outer rings. During the clamping process, the bearing is subjected to uniform force and is not easily deformed. The center rotation design of the rotating disk reduces the eccentric wobbling when the bearing rotates. Combined with the stable clamping of the clamping plate, it ensures that the bearing posture is consistent during testing, effectively improving the accuracy of the test data. At the same time, the coordinated operation of each component reduces the testing error and improves the practicality of the equipment. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Reference Figure 1-4This utility model provides a bearing testing device, including a base 1, a support leg 101 fixedly connected to the bottom of the base 1, a rotating disk 102 rotatably connected to the top of the base 1, a connecting frame 103 fixedly connected to the back of the base 1, a fixed seat 3 fixedly connected to the bottom of the connecting frame 103, a fixed seat 3 fixedly connected to the bottom of the fixed seat 3, a motor 302 fixedly connected to the top of the fixed seat 3, a first gear 303 fixedly connected to the output end of the motor 302, a second gear 304 meshing with the tooth end of the first gear 303, a plurality of rotating grooves 305 provided on the surface of the second gear 304, an adjusting bolt 306 provided inside the rotating groove 305, a movable block 307 fixedly connected to the top of the adjusting bolt 306, and a fixed clamping block 308 fixedly connected to one end of the movable block 307.

[0021] The base 1 provides a basic installation platform for the equipment, and its bottom support legs 101 provide stable support for the entire equipment. The rotating disk 102 on the top of the base 1 can rotate relative to the base 1 to support the bearing to be tested and drive it to rotate for testing purposes. The connecting frame 103 on the back of the base 1 suspends the fixed seat 3 above the rotating disk 102, providing an installation carrier for the clamping structure related to the test. After the motor 302 on the top of the fixed seat 3 is started, its output end drives the first gear 303 to rotate. Since the teeth of the first gear 303 and the second gear 304 mesh, the first gear 303 will drive the second gear 304 to rotate synchronously. When the second gear 304 rotates, the rotating groove 305 on its surface will drive the movable block 307 to move through the internal adjusting bolt 306, thereby causing the fixed clamping block 308 at one end of the movable block 307 to move closer to or away from the bearing to be tested, thereby achieving clamping and fixing of the inner ring of the bearing.

[0022] In a preferred embodiment, the bottom of the fixed base 3 is provided with a plurality of sliding grooves 301, and the movable block 307 is located inside the sliding grooves 301.

[0023] Multiple grooves 301 at the bottom of the fixed base 3 provide a motion track for the movable block 307. When the second gear 304 drives the movable block 307 to move through the rotating groove 305 and the adjusting bolt 306, the movable block 307 will slide along the extension direction of the groove 301. The groove 301 restricts the degree of freedom of movement of the movable block 307, so that it can only move in a preset direction, thereby ensuring that the fixed clamping block 308 at one end of the movable block 307 clamps or releases the bearing.

[0024] In a preferred embodiment, a plurality of cylinders 2 are fixedly connected to the top of the rotating disk 102, a telescopic rod 201 is movably connected to one end of the cylinder 2, a clamping plate 202 is fixedly connected to one end of the telescopic rod 201, and a placement plate 203 is fixedly connected to the bottom of the clamping plate 202.

[0025] The bearing to be tested is placed on the placement plate 203, which provides bottom support for the bearing. After the multiple cylinders 2 on the top of the rotating disk 102 are started, the telescopic rod 201 at its output end will extend and retract in the horizontal direction, causing the clamping plate 202 at one end of the telescopic rod 201 to move synchronously. When the telescopic rod 201 extends, the clamping plate 202 moves closer to the bearing and clamps the outer surface of the bearing.

[0026] In a preferred embodiment, the rotating disk 102 is horizontally positioned at the top center of the base 1, and the axis of the rotating disk 102 coincides with the vertical center line of the base 1.

[0027] The rotating disk 102 is horizontally positioned at the top center of the base 1, and its axis coincides with the vertical centerline of the base 1. This means that the rotation center of the rotating disk 102 is consistent with the geometric center of the base 1. When the rotating disk 102 rotates, the bearing placed on top of it will perform circular motion around the vertical centerline of the base 1, ensuring that the bearing remains in the central area of ​​the equipment during rotation, thus avoiding wobbling or positional shift caused by eccentric rotation.

[0028] In a preferred embodiment, the first gear 303 and the second gear 304 are both located in the area below the fixed base 3, and the first gear 303 and the second gear 304 are parallel to each other.

[0029] Parallel gear transmissions offer high efficiency and good meshing stability, reducing energy loss and component wear during transmission and extending equipment lifespan.

[0030] In a preferred embodiment, the clamping plate 202 is horizontally connected to the output end of the cylinder 2 via a telescopic rod 201, and the clamping plate 202 is located above the placement plate 203.

[0031] The clamping plate 202 is horizontally connected to the output end of the cylinder 2 via the telescopic rod 201 and is located above the placement plate 203. This makes the movement direction of the clamping plate 202 parallel to the support surface of the placement plate 203. When the bearing is placed on the placement plate 203, the cylinder 2 drives the telescopic rod 201 to extend and retract horizontally, causing the clamping plate 202 to move closer to or further away from the bearing in the horizontal direction above the placement plate 203. The contact force between the clamping plate 202 and the bearing acts in the horizontal direction, which works in conjunction with the placement plate 203 to support the bottom of the bearing.

[0032] The foregoing description of an exemplary embodiment of a bearing testing device provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
