Description

Technical Field

[0001] The utility model relates to the technical field of thrust bearing vibration detection, in particular to a thrust bearing axial anti-seismic capability detection device. Background Art

[0002] Thrust bearings are special bearings used to bear axial forces, that is, bearings that bear forces in the direction parallel to the axis. Thrust bearings are also called thrust bearings. Thrust bearings are generally composed of two thrust washers or more thrust washers and several rolling elements. Generally, thrust washers are divided into shaft pieces and seat pieces. The most common type of rolling element is an iron or copper cage combined into a whole. The most common type of this type of bearing is a steel ball thrust bearing.

[0003] After searching, the Chinese publication number is: CN 216559723 U. A fixing structure for a rolling bearing vibration detector is disclosed, which belongs to the field of bearing vibration detection technology. The key points of its technical solution include a detector body, a bottom of the detector body is fixedly connected with a support leg, the number of the support legs is four, and they are distributed at the four corners of the detector body, the top of the detector body is fixedly connected with an adjustment device, the front side of the detector body is movably connected with a transmission column, and the top of the detector body is fixedly connected with a support mechanism; the support mechanism includes a roller, a support shell and a first cylinder, which solves the problem that the existing bearing vibration detector has a poor fixing effect when performing vibration detection on the rolling bearing. When the rolling bearing is tested, long-term rotation will cause the fixing part to become loose, thereby affecting the test of the rolling bearing, causing inaccurate test data, and bringing inconvenience to the user's test work.

[0004] However, most vibration detectors, when loading the thrust bearing, manually fix the thrust bearing on the placement table of the cylinder, and then push the thrust bearing into the detector for testing through the cylinder. This means that when loading, the bearing needs to be fixed on the placement table of the cylinder, pushed into the detector, and then the limit is released before testing, which greatly reduces the testing efficiency. In view of this, we propose a thrust bearing axial seismic resistance testing device. Utility Model Content

The push plate 25 can be limited by the cooperation between the slide groove 23 and the limit rod 24, so that the push plate 25 can move stably. The outer arc surface of the limit rod 24 is sleeved with a spring 26. The limit rod 24 is fixedly connected to one end of the spring 26, and the push plate 25 is fixedly connected to the other end of the spring 26. Through the elastic force of the spring 26, when the push plate 25 is not limited, the push plate 25 can be pushed to move in the direction of the vibration detector body 1. The inner arc surface of the receiving barrel 21 is provided with a groove 27, and the inner surface of the groove 27 is penetrated by a slide bar 28 and is slidably connected with the slide bar 28. Through the cooperation between the groove 27 and the force plate 29, the force plate 29 can be received in the groove 27. At the same time, under normal circumstances, the force plate 29 always protrudes from the inner surface of the receiving barrel 21 through the cooperation between the slide bar 28 and the spring 210. The upper surface of the slide bar 28 is fixedly connected with the force plate 29, and the outer arc surface of the slide bar 28 is sleeved with the spring 210. The slide bar 28 is fixedly connected to one end of the spring 210.

[0028] Embodiment 2

[0029] See also Figure 1-Figure 5 On the basis of the first embodiment, the present invention provides a technical solution: preferably, a limiting mechanism 3 is arranged on the upper surface of the vibration detector body 1, and the limiting mechanism 3 includes a detector body 31, and the front surface of the detector body 31 is fixedly connected with a fixed shaft 32, and the front surface of the fixed shaft 32 is provided with a limiting groove 33, and the inner surface of the limiting groove 33 is slidably connected with a limiting block 34, and the upper surface of the limiting block 34 is arranged in a curved surface. Through this arrangement, after the bearing is pushed into the detector body 31 through the push plate 25, the inner surface of the bearing will contact with the curved surface of the limiting block 34, and the limiting block 34 will shrink into the limiting groove 33, and the inner surface of the limiting groove 33 is penetrated by a vertical rod 35 and fixedly connected with the vertical rod 35. Through the cooperation of the limiting groove 33 and the vertical rod 35, the limiting block 34 is limited to ensure that the limiting block 34 can stably move up and down in the limiting groove 33, and the vertical rod 35 penetrates the limiting block 3 4 and is slidably connected with the limit block 34. The front surface of the limit block 34 is provided with a speed limiting groove 36, and the inner surface of the speed limiting groove 36 is slidably connected with the speed limiting block 37. The cross-sectional shape of the speed limiting block 37 is triangular. When the limit block 34 shrinks into the limit groove 33, the inclined surface of the speed limiting block 37 will be squeezed by the triangular groove 39, and the speed limiting block 37 will shrink into the speed limiting groove 36. At the same time, the speed limiting block 37 will move upward through the elastic force of the spring three 38, so that the limit block 34 is completely in close contact with the inner surface of the bearing, thereby realizing the function of limiting the bearing entering the detector body 31. The speed limiting groove 36 and the speed limiting block 37 cooperate with each other, the speed limiting block 37 is fixedly connected to one end of the spring three 38, and the speed limiting groove 36 is fixedly connected to the other end of the spring three 38. The front surface of the fixed shaft 32 is provided with a triangular groove 39, and the inner surface of the triangular groove 39 is slidably connected with the inclined surface of the speed limiting block 37.

[0030] In this embodiment, through the setting of the limit block 34, the speed limit block 37 and the spring 38, after the bearing is pushed into the detector body 31 through the push plate 25, the speed limit block 37 cooperates with the triangular groove 39, so that the limit block 34 can limit the bearing more stably.

[0031] Working principle: when the thrust bearing needs to be tested, the bearing is manually placed in the receiving barrel 21 through the discharge groove 22. The gravity of the bearing will press the force plate 29 to shrink into the groove 27. At this time, the force plate 29 will drive the slide bar 28 to move downward. The slide bar 28 drives the buckle 212 to move from the lower surface of the push plate 25 through the abutment plate 211 and detach from the push plate 25. When the push plate 25 loses its limit, the push plate 25 is pushed toward the detector body 31 by the elastic force of the spring 26. The contact ring 213 pushes the bearing into the detector body 31 and makes the bearing stuck in the fixed position. On the shaft 32, after the bearing contacts the limit block 34, the inner surface of the bearing contacts the curved surface of the limit block 34, so that the limit block 34 shrinks into the limit groove 33. The inclined surface of the speed limit block 37 is squeezed by the triangular groove 39, and the speed limit block 37 shrinks into the speed limit groove 36. At the same time, the speed limit block 37 moves the limit block 34 upward through the elastic force of the spring 38, so that the limit block 34 is completely in close contact with the inner surface of the bearing, thereby realizing the function of limiting the bearing entering the detector body 31. When the bearing is limited, the detector body 31 performs vibration detection on the bearing.
