[0001] This utility model relates to the field of adapter sleeve technology, specifically a highly versatile bearing adapter sleeve. Background Technology

[0002] The bearing adapter sleeve is the most commonly used component for positioning bearings on a cylindrical shaft. Its main feature is its ease of installation, as it does not require additional fixing to the shaft.

[0003] Currently, when using bearing adapter sleeves, different adapter sleeve models are required for shafts with different outer diameters, resulting in low versatility and a narrow applicable range for the same adapter sleeve. Therefore, we propose a bearing adapter sleeve with high versatility. Utility Model Content

[0004] The purpose of this utility model is to provide a highly versatile bearing adapter sleeve, which is easy to fix onto shafts with different outer diameters, applicable to more usage scenarios, and improves the versatility of the adapter sleeve. It solves the problem that current bearing adapter sleeves require the use of a specific adapter sleeve model for shafts with different outer diameters, resulting in low versatility and a narrow applicable range for the same adapter sleeve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highly versatile bearing retaining sleeve, comprising a locking nut, a bushing, and a washer. The bushing contains a plurality of fixed plates arranged in a circular array at equal intervals. Slide plates are inserted into the gaps between adjacent fixed plates. A triangular wedge A is connected to the outer surface of each slide plate near the outer surface of the bushing. A rotating ring is installed inside the bushing, with both the slide plates and fixed plates located within the rotating ring. A plurality of triangular wedges B are arranged in a circular array at equal intervals inside the rotating ring. A limiting ring is provided on one side of the outer surface of the bushing. A rotating shaft is installed on the outer surface of the limiting ring, with a worm gear connected to one end of the rotating shaft inside the limiting ring. A worm wheel is connected to the one end of the rotating ring inside the limiting ring, and the worm wheel and worm gear mesh with each other.

[0006] Preferably, the outer surface of the bushing is provided with an external thread on the side opposite to the limiting ring, and the locking nut and washer are both sleeved on the outer surface of the bushing.

[0007] Preferably, the outer surface of the locking nut is provided with a plurality of engagement grooves in a ring array at equal intervals, and the outer surface of the washer is provided with a plurality of limiting teeth in a ring array at equal intervals.

[0008] Preferably, the inner wall of the washer is provided with a limiting protrusion, and the outer surface of the bushing is provided with a groove on the side near the external thread, with the limiting protrusion located inside the groove.

[0009] Preferably, the inner wall of the bushing is provided with an internal thread on the side opposite to the limiting ring, and a fixing ring is installed on the side of the bushing opposite to the limiting ring. The outer surface of the fixing ring is provided with a fixing thread, and the fixing thread and the internal thread mesh with each other. An annular groove is provided on the inner side of the fixing ring, and a movable ring is provided inside the annular groove. A plurality of slots are provided in an annular array at equal intervals on the inner side of the movable ring, and the end of the fixing plate is located inside the slot.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a bushing, a limiting ring, a worm gear, a worm wheel, a rotating shaft, a fixing plate, a sliding plate, triangular wedge block A, triangular wedge block B, a rotating ring, a nut, and a washer, achieves the effect of easily fixing the adapter sleeve to shafts with different outer diameters, making it suitable for more application scenarios and improving the versatility of the adapter sleeve. The shaft passes through the inside of the bushing, drives the worm gear to rotate through the rotating shaft, and then drives the rotating ring to rotate through the transmission of the worm wheel and worm gear. Because the inclined surfaces of triangular wedge block A and triangular wedge block B are in contact, triangular wedge block A is forced to drive the sliding plate to move towards the shaft, and the sliding plate contacts the outer surface of the shaft, thereby fixing the bushing to shafts with different outer diameters. Then, the bearing, nut, and washer are fitted onto the outer surface of the bushing.

[0012] 2. This utility model improves the stability of the fixing plate by setting a fixing ring, internal thread, fixing thread, annular groove, movable ring and slot. The end of the fixing plate is inserted into the slot inside the movable ring, the movable ring is placed inside the annular groove, and then the fixing ring is screwed into the bushing through the internal thread and fixing thread and is fixed, thus limiting and fixing the end of the fixing plate.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model proposes a highly versatile bearing locking sleeve, comprising a locking nut 2, a bushing 4, and a washer 7. The bushing 4 has several fixing plates 11 arranged in a circular array at equal intervals. Slide plates 9 are inserted into the gaps between adjacent fixing plates 11, allowing the slide plates 9 to slide within these gaps. A triangular wedge A10 is connected to the outer surface of each slide plate 9 near the outer surface of the bushing 4. A rotating ring 20 is installed inside the bushing 4, with the slide plates 9 and fixing plates 11 located inside the rotating ring 20. Inside the rotating ring 20, several triangular wedges B22 are installed in a circular array at equal intervals. Triangular wedges B22 and triangular wedges A10 correspond one-to-one, and their inclined surfaces are in contact. A limit ring 5 is provided on one side of the outer surface of the bushing 4. A rotating shaft 6 is installed on the outer surface of the limit ring 5. The end of the rotating shaft 6 located inside the limit ring 5 is connected to a worm gear 21. The end of the rotating shaft 6 located outside the limit ring 5 is provided with a hexagonal groove. The rotating shaft 6 is rotated by a hexagonal wrench and the hexagonal groove, which in turn drives the worm gear 21 to rotate.

[0023] The rotating ring 20 is connected to a worm gear 23 at one end inside the limiting ring 5, and the worm gear 23 meshes with the worm 21. The outer surface of the bushing 4 is provided with an external thread 12 on the side away from the limiting ring 5. The nut 2 and the washer 7 are both fitted onto the outer surface of the bushing 4. The nut 2 is fixed to the outer surface of the bushing 4 by the external thread 12. The outer surface of the nut 2 is provided with a number of engagement grooves 3 in a ring array at equal intervals. The wrench is used to turn the nut 2 with the engagement grooves 3. The outer surface of the washer 7 is provided with a number of limiting teeth 18 in a ring array at equal intervals. The limiting teeth 18 are bent and inserted into the engagement grooves 3 to restrict the rotation of the nut 2 and prevent the nut 2 from loosening.

The outer surface of the bushing 4 is provided with a groove 13 on the side near the external thread 12, and the limiting protrusion 19 is located inside the groove 13.

[0024] In use, the shaft passes through the inside of the bushing 4, drives the worm 21 to rotate through the rotating shaft 6, and then drives the rotating ring 20 to rotate through the worm wheel 23 and the worm 21. Because the inclined surfaces of the triangular wedge block A10 and the triangular wedge block B22 are in contact, the triangular wedge block A10 is forced to drive the slide plate 9 to move towards the shaft, and the slide plate 9 contacts the outer surface of the shaft, thereby fixing the bushing 4 on shafts with different outer diameters. Then, the bearing, nut 2 and washer 7 are fitted onto the outer surface of the bushing 4.
