Description

Technical Field

[0001] This utility model relates to the field of bearing measurement technology, specifically to a device for measuring the radial clearance of cylindrical roller bearings. Background Technology

[0002] With the widespread use of cylindrical roller bearings in aviation, aerospace, shipbuilding and other fields, the demand is constantly increasing. As an important characteristic of bearings, radial clearance must be strictly controlled. The radial clearance of cylindrical roller bearings is generally measured using special instruments.

[0003] In the prior art, patent document CN218723760U discloses a radial clearance measuring device for cylindrical roller bearings, belonging to the field of bearing testing technology. It includes a device platform, with a fixed frame fixedly connected to the upper surface of the platform. A clamping device is fixedly connected to the lower surface of the fixed frame, and a moving device is fixedly connected to the upper surface of the clamping device. The upper surface of the moving device is fixedly connected to the lower surface of the fixed frame. This radial clearance measuring device for cylindrical roller bearings, by setting up the moving device, activates a first electric push rod. The first electric push rod retracts and drives the support plate and rack to move synchronously. The two support plates drive two fixed rods and two clamping plates to clamp the bearing to be measured. This avoids the difficulty in measuring cylindrical roller bearings of various specifications and models during use, and effectively fixes the cylindrical roller bearing, preventing deviations from affecting the measurement results, thus improving testing efficiency and accuracy.

[0004] To address the problem that existing measuring devices struggle to measure cylindrical roller bearings of various specifications, current technology employs a method that uses a combination of a device platform, a fixed frame, a clamping device, a moving device, and a measuring equipment to assist in clamping the bearings. However, this method still suffers from the inconvenience of adjusting the position of the measuring device during use, thus reducing the practicality of the measuring device. Utility Model Content

The support assembly includes a support frame 32, the bottom surface of which is fixedly connected to the upper surface of the worktable 1. A telescopic column is disposed inside the support frame 32. The clamping assembly includes a fixing plate 31, the bottom surface of which is fixedly connected to the upper surface of the worktable 1. The upper surface is fixedly connected to a hydraulic cylinder 33, which is detachably connected to the outer surface of the fixed plate 31. The telescopic end of the hydraulic cylinder 33 is fixedly connected to a movable plate 34. The outer surface of the movable plate 34 is fixedly connected to an arc-shaped clamping plate 36. The outer surface of the movable plate 34 is fixedly connected to a limiting plate 35 that slides with the inner wall of the fixed plate 31. When using the cylindrical roller bearing radial clearance measuring device, the cylindrical roller bearing is first placed between the arc-shaped clamping plates 36. Then, the hydraulic cylinder 33 is started by the PLC controller 2, which drives the movable plates 34 to move closer to each other under the limit of the limiting plate 35, thereby assisting in clamping and limiting the cylindrical roller bearing. Before clamping, the outer ring of the cylindrical roller bearing is pressed against the outer surface of the support frame 32, thereby assisting in supporting the outer ring.

[0030] Example 2

[0031] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjustment component includes a limit guide rail 41, the outer surface of the limit guide rail 41 is fixedly connected to the outer surface of the housing of the PLC controller 2, a movable frame 42 is slidably connected to the inner wall of the limit guide rail 41, and an adjustment bolt 43 that is movably engaged with the outer surface of the limit guide rail 41 is threadedly connected to the inner wall of the movable frame 42. The measuring component includes a movable block 44, the outer surface of the movable block 44 is slidably connected to the inner wall of the movable frame 42, and an adjustment bolt 43 that is movably engaged with the outer surface of the movable frame 42 is threadedly connected to the inner wall of the movable block 44. 5. An electric telescopic rod 46 is detachably connected to the upper surface of the movable block 44. A lifting frame is detachably connected to the telescopic end of the electric telescopic rod 46. A limiting plate 47 is fixedly connected to the outer surface of the lifting frame and slidably connected to the outer surface of the movable block 44. A dial indicator measuring device 48 is detachably connected to the outer surface of the lifting frame. A limiting frame 49 is fixedly connected to the outer surface of the lifting frame. A movable plate 410 is slidably connected to the inner wall of the limiting frame 49. An adjusting bolt 411 is threadedly connected to the inner wall of the movable plate 410 and movably engaged with the outer surface of the limiting frame 49. The upper surface of the movable plate 410 is detachably connected to... An electric telescopic rod 412 is connected to the telescopic end of the electric telescopic rod 412. A pressure sensor 415 is fixedly connected to the telescopic end of the electric telescopic rod 412. A fixed column 414 is fixedly connected to the bottom of the pressure sensor 415. An elastic column 413 is sleeved on the outer surface of the pressure sensor 415. After the bearing is fixed, the position of the moving frame 42 is adjusted by rotating the adjusting bolt 43 in conjunction with the limit guide rail 41 and the moving frame 42. After adjustment, the position of the moving block 44 is adjusted by rotating the adjusting bolt 45 in conjunction with the moving block 44 and the moving frame 42. After adjustment, the electric telescopic rod 46 is started by controlling the PLC controller 2. The movable lifting frame rises and falls under the limit of the second limiting plate 47, so that the probe of the dial indicator measuring device 48 is pressed against the outer surface of the inner ring of the bearing. Finally, the third adjusting bolt 411 is rotated, so that the second moving plate 410 moves under the limit of the limiting frame 49, so that the fixed column 414 can move to the top of the inner ring. Finally, the second electric telescopic rod 412 is activated to drive the fixed column 414 to rise and fall under the limit of the elastic column 413 and the pressure sensor 415, thereby applying a pressure of 3% of the rated dynamic load of the bearing to the inner ring, and then reading the data of the dial indicator measuring device 48, and measuring different parts multiple times to calculate the radial clearance of the bearing.

[0032] The working principle of this cylindrical roller bearing radial clearance measuring device will be explained in detail below.

[0033] like Figure 1-5As shown, when using the cylindrical roller bearing radial clearance measuring device, the cylindrical roller bearing is first placed between the arc-shaped clamping plates 36. Then, the PLC controller 2 controls the start of the hydraulic cylinder 33, which drives the moving plate 34 to move closer to each other under the limit of the limiting plate 35, thereby assisting in clamping and limiting the cylindrical roller bearing. Before clamping, the outer ring of the cylindrical roller bearing is pressed against the outer surface of the support frame 32 to assist in supporting the outer ring. After the bearing is fixed, the position of the moving frame 42 is adjusted by rotating the adjusting bolt 43 in conjunction with the limiting guide rail 41 and the moving frame 42. After adjustment, the position of the moving block 44 is adjusted by rotating the adjusting bolt 45 in conjunction with the moving block 44 and the moving frame 42. After adjustment, the electric telescopic rod 46 is activated by the PLC controller 2, which drives the lifting frame to rise and fall under the limit of the limiting plate 47. This allows the probe of the dial indicator measuring device 48 to press against the outer surface of the bearing inner ring. Finally, the adjusting bolt 411 is rotated, causing the moving plate 410 to move under the limit of the limiting frame 49. This allows the fixed column 414 to move directly above the inner ring. Finally, the electric telescopic rod 412 is activated, driving the fixed column 414 to rise and fall under the limit of the elastic column 413 and the pressure sensor 415. This applies a pressure of 3% of the bearing's rated dynamic load to the inner ring, allowing the data from the dial indicator measuring device 48 to be read. Multiple measurements are taken at different locations to calculate the bearing's radial clearance.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
