Description

Technical Field

[0001] This utility model relates to the field of bearing adapter sleeve technology, specifically a combined anti-slip bearing adapter sleeve. Background Technology

[0002] The adapter sleeve is the most commonly used component for positioning bearings with tapered bores on cylindrical shafts. This is because it can be used on both smooth and stepped shafts, is easy to install, and requires no additional fixing to the shaft. When used on a smooth shaft, the bearing can be positioned at any point on the shaft. When used with a stepped ring on a stepped shaft, the bearing can be precisely positioned axially, and it also facilitates the removal of the bearing.

[0003] During the installation and tightening process of current bearing adapter sleeves, the adapter bushing is prone to slipping on the optical shaft, affecting the accurate positioning and installation of the adapter sleeve. After the adapter sleeve is installed, the adapter bushing is fixed to the optical shaft by the tightening force at one end, but the other end of the adapter bushing is not under force, resulting in poor fit between the adapter bushing and the optical shaft and easy slippage. To address this, we propose a combined anti-slip bearing adapter sleeve. Utility Model Content

[0004] The purpose of this invention is to provide a combined anti-slip bearing adapter sleeve, which can pre-fix the adapter sleeve during installation to prevent it from sliding on the optical shaft, thereby improving the installation accuracy of the adapter sleeve. It also improves the tightness of the fit between the adapter sleeve and the optical shaft after installation, preventing slippage of the adapter sleeve. This solves the problem that current bearing adapter sleeves are prone to slippage on the optical shaft during installation and tightening, affecting the accurate positioning of the adapter sleeve. Furthermore, after installation, the adapter sleeve is fixed to the optical shaft by the tightening force at one end, but the other end is not stressed, resulting in poor fit between the adapter sleeve and the optical shaft and a tendency to slip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined anti-slip bearing retaining sleeve, comprising a retaining bushing, a shrink band, a locking washer, and a locking mechanism. One side of the outer surface of the retaining bushing is provided with an external thread. On the side of the outer surface of the retaining bushing opposite to the external thread, several insertion ports are arranged in a circular array at equal intervals. Several insertion blocks are fixedly installed at equal intervals on the outer surface of the shrink band. Both ends of the shrink band are fixedly connected to fixing blocks, and the outer surfaces of the two fixing blocks are respectively provided with a through slot and a threaded hole. A screw is movably inserted into the through slot, and the end of the screw is located inside the threaded hole.

[0006] Preferably, the outer surface of the retaining bushing is provided with a shrinkage groove.

[0007] Preferably, a locking washer is movably fitted onto the outer surface of the locking bushing, and the inner wall of the locking washer is provided with a limiting protrusion, which is located inside the shrinkage groove.

[0008] Preferably, the outer surface of the locking washer is provided with a plurality of limiting pieces arranged in a ring array at equal intervals, and the outer surface of the locking washer is provided with a plurality of stepped grooves arranged in a ring array at equal intervals.

[0009] Preferably, the size of the insert is smaller than the size of the socket.

[0010] Preferably, the internal and external threads of the locking inner wall are engaged.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting a set-fit bushing, external thread, locking mechanism, shrink band, fixing hole, through slot, threaded hole, screw, socket, and insert block, achieves a pre-fixing effect on the set-fit bushing during installation, preventing the set-fit bushing from sliding on the optical shaft during installation, thereby improving the installation accuracy of the set-fit bushing and improving the tightness of the fit between the set-fit bushing and the optical shaft after installation, thus preventing the set-fit bushing from sliding. The optical shaft passes through the inside of the set-fit bushing, the shrink band is sleeved on the outer surface of the set-fit bushing, and the insert block is inserted into the socket. Then, the screw is turned, causing the two ends of the shrink band to move in opposite directions. The set-fit bushing is pulled by the shrink band to fit against the outer surface of the optical shaft, preventing the set-fit bushing from sliding when the locking mechanism is turned. At the same time, after the bearing, locking mechanism, and locking washer are installed, the two ends of the set-fit bushing are subjected to force, which improves the tightness of the fit between the set-fit bushing and the optical shaft after installation, thus preventing the set-fit bushing from sliding.

[0013] 2. This utility model achieves easy locking and fixation by setting a stepped groove, a locking washer, and a limiting piece, thus preventing the locking from loosening. After the locking is tightened on the set bushing by external thread, the limiting piece is bent to insert into the stepped groove to restrict the locking rotation and prevent the locking from loosening. Furthermore, since the groove inside the stepped groove gradually decreases from the outer surface of the locking to the axis, it is easy to insert the bent limiting piece into the stepped groove without needing to rotate and fine-tune the locking.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-3 As shown, the present invention proposes a combined anti-slip bearing retaining sleeve, including a retaining bushing 1, a shrink band 2, a locking washer 3, and a locking 4. The outer surface of the retaining bushing 1 is provided with a shrink groove 6, which extends to both ends along the axial direction of the retaining bushing 1. An external thread 7 is provided on one side of the outer surface of the retaining bushing 1. The internal thread of the inner wall of the locking 4 meshes with the external thread 7. A number of insertion ports 5 are arranged in a ring array on the side of the outer surface of the retaining bushing 1 away from the external thread 7. A number of insertion blocks 12 are fixedly installed at equal intervals on the outer surface of the shrink band 2. The size of the insertion block 12 is smaller than the size of the insertion port 5. When the two ends of the shrink band 2 move and close in opposite directions, the insertion block 12 can move inside the insertion port 5. Fixed blocks 10 are fixedly connected to both ends of the shrink band 2. The outer surfaces of the two fixed blocks 10 are respectively provided with a through groove 9 and a threaded hole 11. A screw 8 is movably inserted into the through groove 9, and the end of the screw 8 is located inside the threaded hole 11.

[0023] In use, the optical axis passes through the inside of the locking bushing 1, the shrink band 2 is fitted on the outer surface of the locking bushing 1, and the insert block 12 is inserted into the insert 5. Then, the screw 8 is turned and the two ends of the shrink band 2 move in opposite directions. The locking bushing 1 is pulled by the shrink band 2 and fits against the outer surface of the optical axis to prevent the locking bushing 1 from sliding when the locking 4 is turned. At the same time, after the bearing, locking 4 and locking washer 3 are installed, the two ends of the locking bushing 1 are subjected to force, which improves the tightness between the locking bushing 1 and the optical axis after installation, so as to prevent the locking bushing 1 from sliding.

[0024] Example 2

[0025] like Figure 1 , Figure 4 and Figure 5As shown, the present invention proposes a combined anti-slip bearing retaining sleeve. Compared with the first embodiment, this embodiment further includes a locking washer 3 movably sleeved on the outer surface of the retaining bushing 1. The inner wall of the locking washer 3 is provided with a limiting protrusion 14, and the limiting protrusion 14 is located inside the shrinkage groove 6. The outer surface of the locking washer 3 is provided with a plurality of limiting pieces 15 in a ring array at equal intervals. The outer surface of the locking 4 is provided with a plurality of stepped grooves 13 in a ring array at equal intervals. The locking 4 is tightened by a wrench and the stepped grooves 13.

[0026] In this embodiment, after the locking 4 is tightened and fixed on the set bushing 1 by the external thread 7, the limiting piece 15 is bent and inserted into the stepped groove 13 to restrict the rotation of the locking 4 and prevent the locking 4 from loosening. Since the groove inside the stepped groove 13 gradually decreases from the outer surface of the locking 4 towards the axis, it is convenient to insert the bent limiting piece 15 into the stepped groove 13 without the need to rotate and fine-tune the locking 4.

[0027] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
