Description

Technical Field

[0001] This utility model relates to the field of bearing testing technology, specifically a bearing clearance testing device. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] Currently, bearings need to have their clearance checked before and after use. The purpose of clearance checking is to ensure that the bearing can maintain good performance during operation and extend its service life. At present, most bearing clearance checks are performed using important instruments. However, these instruments can only check small bearings. For some large bearings, the feeler gauge method is still used. However, the feeler gauge method usually involves inserting the feeler gauge into the upper part of the bearing. If other positions need to be checked, it needs to be rotated. However, the weight of large bearings is very heavy, and it is generally not easy to rotate them manually. Therefore, the inspection is too cumbersome and inconvenient.

[0004] A bearing clearance detection device has been designed to address this type of defect and facilitate its use in large bearings. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a bearing clearance detection device, which solves the problem that existing bearing clearance detection devices cannot conveniently detect large bearings.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing clearance detection device, comprising a load-bearing base plate, with side support frames fixedly connected to both sides of the top of the load-bearing base plate, a front baffle fixedly connected between the surfaces of the two side support frames, rotating rods rotatably connected to both sides of the rear of the front baffle via bearing components, rotating wheels fixedly connected to the surface of the rotating rods, the two rotating rods being connected via pulleys and belt drive, and a motor fixedly connected to the rear of the two side support frames via a bracket, with the motor's output shaft fixedly connected to the rear end of the left rotating rod via a coupling.

[0007] Preferably, a grooved rotating seat is fixedly connected to the lower part between the two side support frames, and both rotating wheels are located inside the grooved rotating seat. An electric telescopic rod is fixedly connected to the rear side of the top of the load-bearing base plate through a bracket, and an arc-groove top cover is fixedly connected to the top of the electric telescopic rod through a fixing block.

[0008] Preferably, each of the two side support frames has a polygonal slide rod slidably installed on one side through an opening, and an arc-shaped clamp is fixedly connected to one end of each of the two polygonal slide rods. A guide pulley is provided on one side of the arc-shaped clamp.

[0009] Preferably, a hollow frame is slidably mounted on the surface of the polygonal slide rod, a second spring is fixedly connected between the end of the polygonal slide rod away from the arc-shaped clamp and the inner wall of the hollow frame, a pressure plate is fixedly connected to one side of the hollow frame, and a first spring is sleeved on the surface of the polygonal slide rod. Both sides of the bottom of the arc groove top cover are fixedly connected to inclined pressure frames that cooperate with the pressure plate.

[0010] Preferably, the upper part of the side support frame surface is fixedly connected to a hook by a fixing plate.

[0011] Beneficial effects

[0012] This invention provides a bearing clearance detection device. Compared with existing technologies, it has the following advantages:

[0013] (1) The bearing clearance detection device has a grooved rotating seat between two side support frames, and a rotating wheel is installed on the inner side of the grooved rotating seat using a rotating rod. It is used in conjunction with an arc-shaped clamping plate and an arc-shaped groove top cover. The structure allows the bearing to be placed on top of the rotating wheel. The arc-shaped groove top cover presses down to limit the bearing with the arc-shaped clamping plate, which can effectively ensure the stability of the bearing during detection. It can also start the motor to make the rotating wheel drive the bearing to rotate, which is convenient for detecting different positions of the bearing, improving detection efficiency and making it more convenient to use.

[0014] (2) The bearing clearance detection device is used in conjunction with a sloped pressure frame. The sloped pressure frame can squeeze the bearing plate after the top cover of the arc groove is lowered, so that the arc-shaped clamping plate can make buffered contact with the bearing, avoiding direct hard pressure on the bearing, thus protecting the bearing and reducing damage to the bearing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a bearing clearance detection device, including a load-bearing base plate 1, with side support frames 2 fixedly connected to both sides of the top of the load-bearing base plate 1, a front baffle 20 fixedly connected between the surfaces of the two side support frames 2, rotating rods 4 rotatably connected to both sides of the rear of the front baffle 20 via bearing components, rotating wheels 5 fixedly connected to the surface of the rotating rods 4, the surface of the rotating wheels 5 being covered with a rubber layer to increase friction, the two rotating rods 4 being connected by a pulley 6 and a belt 7, a motor 8 fixedly connected to the rear of the two side support frames 2 via a bracket, the motor 8 being a servo motor, and the output shaft of the motor 8 being fixedly connected to the rear end of the left rotating rod 4 via a coupling, a hook 19 fixedly connected to the upper surface of the side support frame 2 via a fixing plate, a grooved rotating seat 3 fixedly connected to the lower part of the two side support frames 2, the two rotating wheels 5 being located inside the grooved rotating seat 3, an electric telescopic rod 9 fixedly connected to the rear of the top of the load-bearing base plate 1 via a bracket, and an arc groove top cover 10 fixedly connected to the top of the electric telescopic rod 9 via a fixing block.

[0022] In use, the operator first uses a hoisting device to place the bearing between the tops of the two rotating wheels 5. Then, a feeler gauge is hung on the surface of the hook 19. The electric telescopic rod 9 is then activated to push the arc groove top cover 10 down, so that the arc groove top cover 10 fits against the top of the bearing for a limit. While the arc groove top cover 10 is descending, the two inclined pressure frames 18 will contact the pressure plate 17 and squeeze the pressure plate 17. This causes the hollow frame 14 to first use the second spring 16 to push the polygonal slide rod 11 and the two arc surface clamps 12 to move towards each other until the arc surface clamps 12 and the guide pulley 13 squeeze and contact both sides of the bearing. As the inclined pressure frame 18 continues to descend, it will squeeze the pressure plate 17, causing the hollow frame 14 to compress the second spring 16 to further improve the fit between the arc surface clamps 12 and the bearing. Then, the operator inserts the feeler gauge into the top of the inner side of the bearing to check the clearance.

[0023] Furthermore, on the opposite sides of the two side support frames 2, polygonal slide rods 11 are slidably installed through openings. The opposite ends of the two polygonal slide rods 11 are fixedly connected to arc-shaped clamping plates 12. A guide pulley 13 is provided on one side of the arc-shaped clamping plate 12. A hollow frame 14 is slidably installed on the surface of the polygonal slide rods 11. A second spring 16 is fixedly connected between the end of the polygonal slide rod 11 away from the arc-shaped clamping plate 12 and the inner wall of the hollow frame 14. A pressure plate 17 is fixedly connected to one side of the hollow frame 14. A first spring 15 is sleeved on the surface of the polygonal slide rod 11. The second spring 16 has a greater elastic force than the first spring 15. Inclined pressure frames 18 that cooperate with the pressure plate 17 are fixedly connected to both sides of the bottom of the arc groove top cover 10.

[0024] When it is necessary to test other positions, start motor 8 and use pulley 6 and belt 7 to drive rotating wheel 5 to rotate. Under the limit and guidance of guide pulley 13, the bearing rotates to adjust its position. At this time, use feeler gauge to test again. After the test is completed, lift electric telescopic rod 9 and arc groove top cover 10 to replace bearings for testing.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
