Description

Technical Field

[0001] The utility model relates to the field of bearing production, in particular to a bearing testing device convenient for clamping. Background Art

[0002] A bearing reduces friction between mechanical parts by rolling of rolling elements between inner and outer rings. The contact points between the rolling elements and the inner and outer rings are called contact lines, and the pressure on the contact lines is the key to the load capacity that the bearing can withstand. During the operation of the bearing, frictional force will be generated between the rolling elements and the inner and outer rings, which will cause energy loss and heat generation. Therefore, the bearing needs to maintain a certain lubrication state during operation to reduce friction and heat generation.

[0003] Bearing testing is a comprehensive evaluation process aimed at ensuring the quality, performance and safety of bearings. This process covers a comprehensive analysis from appearance inspection to detailed performance parameters, such as dimensional accuracy, rotation smoothness, hardness, material composition and heat treatment effect, etc. In addition, it also includes life testing under simulated actual working conditions, noise level evaluation and sealing performance inspection.

Detailed Description of the Preferred Embodiment

[0021] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , where Figure 1 FIG. 1 is a schematic structural diagram of a preferred embodiment of a bearing testing device that is convenient for clamping provided by the present utility model; Figure 2 is Figure 1 a partial structural schematic diagram of the first sliding frame shown in FIG. 2; Figure 3 is Figure 1 a sectional structural schematic diagram of the right view of the base shown in FIG. 3. A bearing testing device that is convenient for clamping includes: a base 1, a first test assembly 2 is disposed on the left side of the top of the base 1, and a second test assembly 3 is disposed on the right side of the top of the base 1;

[0023] The first test assembly 2 includes a first sliding frame 21 disposed on the left side of the top of the base 1. Two first fixing plates 22 are slidably disposed along the length direction of the inner side of the first sliding frame 21. A first bearing 23 is disposed on the top of the base 1 on the opposite sides of the two first fixing plates 22;

[0024] By rotating the rotating handle 25, the screw 24 is driven to rotate. Then, the side of the screw 24 close to the first sliding frame 21 moves inward, so that the two first fixing plates 22 move relatively. When the two first fixing plates 22 move relatively, the first bearing 23 placed therein is fixed.

[0025] The second test component 3 includes a second sliding frame 31 arranged on the right side of the top of the base 1. Two second fixing plates 32 are slidably arranged inside the second sliding frame 31 along its length direction. A second bearing 33 is arranged on the top of the base 1 on the opposite sides of the two second fixing plates 32.

[0026] Screws 24 are rotatably arranged on the opposite sides of the two first fixing plates 22. One end of each of the two screws 24 away from each other penetrates through the inside of the first sliding frame 21 and extends to its front and back sides. Rotating handles 25 are arranged at one end of each of the two screws 24 away from each other.

[0027] Sliding grooves 26 are opened on the left side of the top of the base 1 and inside the first sliding frame 21. Two push blocks 27 are slidably arranged inside the sliding grooves 26. Threaded blocks 28 are arranged at the bottom of each of the two push blocks 27.

[0028] Through the arrangement of the two push blocks 27, the inside of the first bearing 23 can be fixed, further strengthening the fixing effect of the bearing and avoiding deviation during the strength test.

[0029] A bidirectional threaded lead screw 29 is rotatably arranged longitudinally inside the base 1. The circumferential side of the bidirectional threaded lead screw 29 is threadedly connected to the inside of the two threaded blocks 28. A driving motor 4 for driving the bidirectional threaded lead screw 29 to rotate is arranged on the inner wall of the base 1. The output end on the front of the driving motor 4 is fixedly connected to the rear end of the bidirectional threaded lead screw 29.

[0030] By the rotation of the output end of the driving motor 4, the bidirectional threaded lead screw 29 is driven to rotate, thereby driving the two threaded blocks 28 to move away from each other, causing the two push blocks 27 to move away from each other. One side of the two push blocks 27 away from each other abuts against the inner wall of the first bearing 23 to fix the first bearing 23.

[0031] A support base 34 is arranged on the top of the base 1 and inside the second sliding frame 31. Screws 24 are also arranged at one end of the two second fixing plates 32 away from each other.

[0032] Through the arrangement of the support base 34, the second bearing 33 is prevented from moving left and right during the strength test. And through the arrangement of the two second fixing plates 32, the second bearing 33 is prevented from moving back and forth during the test.

[0033] A placement rack 5 is arranged on the tops of the first sliding frame 21 and the second sliding frame 31. Two hydraulic rods 6 are arranged on the top of the placement rack 5. Two pressing plates 7 are slidably arranged inside the placement rack 5. The telescopic ends at the bottoms of the two hydraulic rods 6 are respectively fixedly connected to the tops of the two pressing plates 7.

[0034] The hydraulic rod 6 is a device that can display the pressing force. When the hydraulic rod 6 drives the pressing plate 7 to cause damage to the bearing, by observing the magnitude of the pressing force, the approximate strength of this batch of bearings can be recorded.

[0035] The working principle of a bearing testing device that is convenient for clamping provided by the present utility model is as follows:

[0036] First step: When in use, place the bearing inside different sliding frames according to the angle to be tested. When it is necessary to test a bearing in a lying flat state, by rotating the handle 25, the rotation of the screw rod 24 is driven, and then the two screw rods 24 move relatively. Through the setting of the first fixing plate 22 rotatably connected thereto, the two first fixing plates 22 move relatively and fix the front and rear sides of the first bearing 23. At this time, by the rotation of the output end of the driving motor 4, the rotation of the bidirectional threaded lead screw 29 is driven, and then the separation movement of the two push blocks 27 is driven, so that the two push blocks 27 abut against the inner wall of the first bearing 23 to improve the fixing effect;

[0037] Second step: After the bearing is fixed, by starting the hydraulic rod 6 at the corresponding top, the corresponding pressing plate 7 inside the placement rack 5 is moved downward. At this time, by observing the pressure displayed by the hydraulic rod 6, the strength of the bearing can be understood.

[0038] Compared with the related technology, a bearing testing device that is convenient for clamping provided by the present utility model has the following beneficial effects:

[0039] By rotating the handle 25 to drive the rotation of the screw rod 24, and then the two screw rods 24 move relatively. Through the setting of the side fixing plate rotatably connected thereto, the two fixing plates move relatively and fix the front and rear sides of the bearing. Through the setting of the two sliding frames, the strength of bearings in different placement states can be tested. The structure is simple and practical, effectively improving the applicable range of the testing device.

[0040] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included within the patent protection scope of the present utility model.
