Abstract
Description
Technical Field
[0001] This utility model relates to a device for detecting the radial clearance of a bearing, and more particularly to a device for detecting the radial clearance of a bearing. Background Technology
[0002] Detecting bearing radial clearance is a crucial step in ensuring the normal operation of bearings. During testing, the bearing is first secured to the shaft, fixing the inner ring in place. Next, a push rod at the bottom is used to assist in lifting the bearing, ensuring its stable position. Then, a gauge is placed on top of the bearing, positioned close to the top of the outer ring. By manually rotating the bearing, the changes in the gauge readings are observed. When the bearing radial clearance changes, the gauge readings will change accordingly, allowing for an accurate assessment of the bearing's radial clearance condition.
[0003] Existing devices exist:
[0004] Complex adjustment and low efficiency: The adjustment of traditional equipment may be cumbersome, especially when switching bearings of different diameters, which requires frequent adjustments, takes a long time, and affects production efficiency.
[0005] Inflexible structure: Existing equipment may lack flexibility and cannot quickly adapt to bearings of different diameters, leading to frequent equipment or tool changes during production, which increases costs and time. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0029] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0030] Existing adjustments are complex and inefficient: traditional equipment adjustments can be cumbersome, especially when switching between bearings of different diameters, requiring frequent adjustments, which is time-consuming and affects production efficiency; the structure is not flexible enough: existing equipment may lack flexibility and cannot quickly adapt to bearings of different diameters, leading to frequent equipment or tool changes during production, increasing costs and time. Therefore, to solve the above problems, this paper proposes the following technical solution:
[0031] Reference Figures 1-4 As shown, a bearing radial clearance detection device includes: a base plate 3, on the surface of the base plate 3 are a bearing seat 6, a second column 7, and a first column 2; the top of the bearing seat 6 is provided with a movable adjusting handle 4 and a top column 5; the top of the second column 7 is equipped with a clamping block 8; the front end of the rod of the clamping block 8 is provided with a detection gauge 9 opposite to the bearing seat 6; the first column 2 is characterized by having a sliding limiting horizontal shaft 1 on its surface, the limiting horizontal shaft 1 including a clamping wheel 11 and a clamping column 12; a detachable positioning block 13 is installed on one side of the clamping column 12, the positioning block 13 cooperates with a sliding groove on the surface of the first column 2; the clamping wheel 11 is threadedly engaged with the front end of the clamping column 12; and a multi-diameter top block is provided on the opposite surface of the clamping column 12 and the clamping wheel 11.
[0032] In this embodiment, the bottom of the device is a base plate 3, and the top is provided with a positioning second column 7, with a clamping block 8 on the top of the second column 7. A measuring gauge 9, specifically a dial indicator, is installed on the crossbar of the clamping block 8. The measuring gauge 9 abuts against the top of the bearing seat 6, and the top of the bearing seat 6 is provided with a top column 5. The top column 5 is rotated by adjusting the handle 4. Rotation causes the thread at the bottom of the top column 5 to engage with the thread inside the bearing seat 6, thereby realizing the up and down movement of the top column 5. In order to accommodate bearings of different diameters, the second column 7 is designed with a rotating structure. The tightness is adjusted by rotation, thereby moving the rod of the clamping block 8 up and down, and thus adjusting the height of the measuring gauge 9.
[0033] The base plate 3 has a first column 2 and a limiting horizontal shaft 1 on its surface for fixing the bearing. The limiting horizontal shaft 1 includes a detachable clamping wheel 11 for easy replacement and installation of the bearing. The clamping column 12 is used to nest the inner ring of the bearing and is mounted on the positioning block 13. The slider 131 of the positioning block 13 engages in the groove of the first column 2 and can be quickly adjusted by bolts.
[0034] A control knob 132 is mounted on the side of the slider 131 for limiting the position of the first slide plate 123 on the side of the second sleeve rod 125. The first sleeve rod 121 is mounted in the middle of the slider 131 for lateral support. To accommodate bearings of different diameters, the front end of the first sleeve rod 121 has a chamfer 122 for clamping. The diameter of the second sleeve rod 125 is larger than that of the first sleeve rod 121, and it slides and engages with the first sleeve rod 121. To prevent the second sleeve rod 125 from wobbling during use and affecting detection accuracy, a second slide plate 126 is provided on the opposite side of the first slide plate 123 and is fixed to the second sleeve rod 125. The second slide plate 126 slides nested within the groove 133 on the surface of the slider 131.
[0035] To accommodate bearings of various diameters, a third sleeve rod 128 is nested within the outer surface of the second sleeve rod 125. The side of the third sleeve rod 128 slides against the first slide plate 123 via a third groove 127. An auxiliary slide plate 124 is also provided on the surface of the first slide plate 123, which slides against the groove of the third groove 127. The auxiliary slide plate 124 has a bent edge on the side away from the first slide plate 123. This bent edge allows the third groove 127 to drag the second sleeve rod 125 when sliding to the bent edge, further improving sliding convenience. Because of the nesting between the third sleeve rod 128 and the second sleeve rod 125, the gap is reduced, thereby improving accuracy during inspection.
[0036] The improved device uses a first sleeve rod 121 to engage with the second sleeve rod 125 and the third sleeve rod 128, thus accommodating bearing inner rings of larger diameters. The surface of the clamping wheel 11 is provided with matching bosses to match the third sleeve rod 128, the second sleeve rod 125, and the first sleeve rod 121, making inspection more convenient. During adjustment, the second sleeve rod 125 can slide on the surface of the first sleeve rod 121 by rotating the control knob 132, or the third sleeve rod 128 can be adjusted independently, achieving a more flexible adjustment method.
[0037] The above description only outlines the basic principles and preferred embodiments of this utility model. Those skilled in the art can make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of this utility model.
[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
