Technical Field

[0001] The utility model relates to the technical field of bearing locking sleeves, and particularly relates to a novel bearing locking sleeve. Background Technique

[0002] A bearing locking sleeve is a device used to fix a bearing or other mechanical parts on a shaft. The bearing locking sleeve is usually made of high-quality steel, has high strength and wear resistance, and can withstand large axial and radial loads. When installing a bearing locking sleeve, it is necessary to pay attention to correctly selecting the size and thread specification of the sleeve to ensure good fit with the shaft and the bearing, and avoid problems such as loosening or wear. The bearing locking sleeve is widely used in various mechanical equipment and projects, such as wind power generation equipment, machine tools, automobiles, airplanes, etc., and plays an important role in the process of bearing installation and fixation. Correct selection and use of the bearing locking sleeve can improve the service life of the bearing and ensure the normal operation of mechanical equipment.

[0003] The inner diameter size of the existing bearing locking sleeve is fixed, and the inner diameter of the bearing locking sleeve cannot be changed, so it cannot be used on shafts with different outer diameters, which affects the applicability of the bearing locking sleeve. For this reason, we propose a novel bearing locking sleeve. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel bearing locking sleeve, which can conveniently change the inner diameter of the bearing locking sleeve, so as to solve the problem that the inner diameter size of the existing bearing locking sleeve is fixed, the inner diameter of the bearing locking sleeve cannot be changed, and it cannot be used on shafts with different outer diameters, which affects the applicability of the bearing locking sleeve.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A novel bearing locking sleeve, including a main body and a variable diameter ring. Among them, a clamping hole is provided in the middle of one side of the main body, and the variable diameter ring is installed in the clamping hole through a sliding table. A locking ring is installed on the outer surface of the main body, and a locking column is installed on one side of the top of the main body through a thread. A locking block is installed at the end of the locking column inside the main body.

[0006] Preferably, a locking groove is installed on the outer surface of the variable diameter ring at the position of the locking block, and the locking block is clamped inside the locking groove.

[0007] Preferably, a moving groove is provided inside the main body at the position of the locking block, and the locking block can slide inside the moving groove.

[0008] Preferably, a sliding groove is provided inside the main body at the position of the sliding table, and the sliding table is clamped inside the sliding groove.

[0009] Preferably, an extrusion platform A is provided in the middle of the outer surface of the main body, and an extrusion hole A is provided on the inner surface of the locking ring at the position of the extrusion platform A.

[0010] Preferably, an extrusion platform B is provided in the middle of the outer surface of the main body, and an extrusion hole B is provided on the inner surface of the locking ring at the position of the extrusion platform B.

[0011] Preferably, clamping grooves are provided at both the top and bottom of the locking ring, and opening grooves are provided at the four corners on one side of the main body and the diameter-changing ring.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By providing a slider, a sliding groove, a diameter-changing ring and a main body, the present utility model achieves the effect of changing the diameter of the main body, so as to solve the problem that the inner diameter size of the existing bearing locking sleeve is fixed, the inner diameter of the bearing locking sleeve cannot be changed, and it cannot be used on shafts with different outer diameters, affecting the applicability of the bearing locking sleeve. It is convenient to use on shafts with different outer diameters, thereby improving the applicability of the bearing locking sleeve.

[0014] 2. By providing a locking post, a locking block and a locking groove, the present utility model achieves the effect of quickly locking the diameter-changing ring, so as to solve the problem that the existing diameter-changing ring is fixed relatively simply, and the diameter-changing ring is prone to looseness during use, affecting the locking effect of the bearing locking sleeve. The loosening probability of the bearing locking sleeve is reduced, thereby ensuring the locking effect of the bearing locking sleeve.

[0015] 3. By providing an extrusion platform A, an extrusion platform B, an extrusion hole A and an extrusion hole B, the present utility model achieves the effect of double extrusion on the main body and the diameter-changing sleeve, so as to solve the problem that the existing locking ring uses a single extrusion force to deform and extrude the main body, and the deformation effect of the main body and the diameter-changing sleeve is poor, affecting the locking firmness of the main body and the diameter-changing sleeve. The locking firmness of the main body and the diameter-changing sleeve is improved. BRIEF DESCRIPTION OF THE DRAWINGS
