Description

Technical Field

[0001] This utility model relates to the field of bearing dust prevention detection technology, specifically a clutch bearing dust prevention detection device. Background Technology

[0002] Bearings are precision mechanical components that convert the sliding friction between the clutch drive shaft and the bearing housing into rolling friction, thereby reducing frictional losses. To reduce frictional resistance during operation, lubricating oil is applied inside the bearing. However, the bearing is located at the opening between the clutch drive shaft and the clutch housing, allowing dust to enter the bearing through this opening. This dust mixes with the lubricating oil, reducing its lubricating effect. Therefore, bearings need to be tested for dust resistance during production. However, current bearing testing methods primarily involve using a blower to blow dust away from the bearing and then checking the internal dust levels after a period of time. During this testing, the bearing is stationary. In actual operation, the bearing's dust-resistant structure will wear down and develop gaps due to dimensional deviations. The testing process differs significantly from the actual working environment, leading to inaccurate test results. Utility Model Content

[0018] Please see Figure 1-4 This utility model provides a technical solution: a clutch bearing dustproof detection device, including a detection cylinder 1, characterized in that: a placement plate 2 is fixedly connected to the inner side wall of the detection cylinder 1, a placement through hole is provided in the middle of the placement plate 2, a bearing for detection and a rotating shaft 5 for driving the bearing to rotate are placed in the middle of the placement through hole, a drive plate 6 for driving the rotating shaft 5 to rotate for detection is inserted into the upper end of the rotating shaft 5, and the detection device also includes a motor, the drive plate 6 is connected to the power output end of the motor, driving the drive plate 6 and the rotating shaft 5 to rotate;

[0019] The right side of the drive plate 6 is provided with a telescopic groove 9, and a telescopic protrusion 10 is slidably connected in the telescopic groove 9. An elastic sheet 11 is fixedly connected to the inner side wall of the telescopic groove 9 to control the telescopic protrusion 10 to pop out and limit and fix the drive plate 6 and the rotating shaft 5. When the rotating shaft 5 moves up and down along the drive plate 6, the telescopic protrusion 10 is located in the telescopic groove 9.

[0020] At least four clamping plates 4 for clamping and fixing the bearing are slidably connected to the upper end of the placement plate 2. Guide blocks 14 are fixedly connected to the side ends of the clamping plates 4. A fixing ring 3 for squeezing and driving the guide blocks 14 is threadedly connected to the inner wall of the detection cylinder 1.

[0021] An auxiliary shaft 7 is rotatably connected to the lower end of the detection cylinder 1. The lower half of the auxiliary shaft 7 passes through the detection cylinder 1. A dust-generating fan blade 8, simulating dust generation in the actual environment, is fixedly connected to the middle of the auxiliary shaft 7. A snap-fit ​​gear 13, which is snapped and fixed to the rotating shaft 5, is fixedly connected to the upper end of the auxiliary shaft 7.

[0022] The upper half of the clamping plate 4 has an arc-shaped structure, which can guide the placement of the bearing and enable the bearing to be quickly placed on the placement tray 2. The lower half of the clamping plate 4 has a vertical structure. The clamping plates 4 work together to clamp and fix the bearing. When the clamping plate 4 moves toward the bearing, it can clamp and fix the outer ring of the bearing.

[0023] Multiple control handles 16 are fixedly connected to the upper end of the fixed ring 3. The inner sidewall of the fixed ring 3 is inclined, and multiple balls 15 are embedded in the inner sidewall. The sidewall of the guide block 14 near the fixed ring 3 is inclined, and a part of the guide block 14 and a part of the fixed ring 3 are overlapped. After the bearing is placed, the fixed ring is rotated by the control handles 16. The inner sidewall of the fixed ring 3 can squeeze the guide block 14, thereby pushing the guide block 14 and the clamping plate 4 to move and clamp and fix the outer ring of the bearing.

[0024] The sidewall of the rotating shaft 5 has a stepped structure, and the two ends of the rotating shaft 5 pass through the bearing.

The elastic sheet 11 is an arc-shaped iron sheet, and the side end of the elastic sheet 11 abuts against the side end of the telescopic protrusion 10. The rotating shaft 5 can move up and down along the drive plate 6, which facilitates the placement and removal of the bearing. When the locking gear 13 and the locking tooth hole 12 are engaged with each other, the telescopic protrusion 10 is popped out by the elastic sheet 11, thereby limiting and fixing the rotating shaft 5 and the drive plate 6 to prevent the rotating shaft 5 from moving during the inspection process. The telescopic protrusion 10 also indicates that the rotating shaft 5 and the inner ring of the bearing are installed and can be inspected.
