Description

Technical Field

[0001] The utility model relates to the technical field of deep groove ball bearings, in particular to a combined deep groove ball bearing. Background Technique

[0002] The original name of the deep groove ball bearing is single row radial ball bearing, which is the most widely used rolling bearing. Its characteristics are small friction resistance, high speed, and can be used on parts that can bear radial load or combined load of radial and axial acting simultaneously, and can also be used on parts that bear axial load, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

[0003] Chinese Patent Publication No. CN210949524U, publication time July 7, 2022, discloses a bearing, which includes an outer ring, an inner ring, a plurality of balls and a ball fixing ring. The inner ring is arranged inside the outer ring, and the surfaces of the inner ring facing the outer ring and the outer ring facing the inner ring respectively have grooves. A plurality of balls are respectively arranged in the grooves of the inner ring and the outer ring, and the distance between every two adjacent balls is equal. The ball fixing ring is arranged between the inner ring and the outer ring and has a plurality of openings. Each opening is sleeved on the outer surface of a ball, and the opening sleeved on each ball does not affect the rotation of the ball.

[0004] Most of the existing deep groove ball bearings such as the above are composed of an outer ring, balls, a cage and an inner ring. In the specific implementation process, there is mostly no protection mechanism between the inner ring and the outer ring. Some relatively large impurities are easy to invade between the inner ring and the outer ring, affecting the operation of the balls, increasing the wear of the bearing, and even directly causing the bearing to jam. Therefore, it is urgent to propose a corresponding combined deep groove ball bearing to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a combined deep groove ball bearing to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A combined deep groove ball bearing includes a bearing body. The bearing body includes an outer ring, an inner ring and balls. Outer fixing rings and inner fixing rings are respectively fixedly connected to the outer walls of the outer ring and the inner ring. Inner sleeve rings and outer sleeve rings are respectively fixedly installed on the outer walls of the outer fixing rings and the inner fixing rings. The inner sleeve rings and the outer sleeve rings are stacked at intervals, and the cross-sections of the inner sleeve rings and the outer sleeve rings are both in an S-shaped structure.

[0008] Preferably, inner mounting blocks and outer mounting blocks are respectively fixedly installed on the outer walls of the arc-shaped ends of the inner fixing ring and the outer fixing ring. The inner mounting blocks are fixedly connected to the inner ring through fastening rods, and the outer mounting blocks are fixedly connected to the outer ring through fixing rods.

[0009] Preferably, an installation sleeve is fixedly connected to the outer surface wall of the inner ring. A locking rod is screwed and connected to the inner surface wall of the arc-shaped end of the installation sleeve. The outer installation block is integrally formed with an extension plate, and an installation rod is screwed and connected to the inner surface wall of the extension plate.

[0010] Preferably, rubber blocks II are press-fitted inside the inner installation block, the outer installation block and the extension plate. Multiple groups of the rubber blocks II are respectively abutted against the outer surface walls of the fastening rod, the installation rod and the fixing rod.

[0011] Preferably, a connection ring fixedly connected to the installation sleeve is arranged outside the locking rod. A rubber block I is press-fitted inside the connection ring, and the rubber block I is abutted against the top of the locking rod.

[0012] Preferably, reinforcing ribs are embedded inside both the outer sleeve ring and the inner sleeve ring.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, the inner fixing ring, the outer sleeve ring and the inner ring are fixed through the inner installation block and the fastening rod. The outer fixing ring, the inner sleeve ring and the outer ring are fixed through the outer installation block and the fixing rod. The outer sleeve ring and the inner sleeve ring with an S-shaped cross-section are in a spaced and overlapping state. The outer sleeve ring and the inner sleeve ring move along with the inner ring and the outer ring respectively, and the inner sleeve ring and the outer sleeve ring do not come into contact during the movement process. In this way, without affecting the movement of the outer ring and the inner ring, the long channel between the inner sleeve ring and the outer sleeve ring can effectively prevent dust between the inner ring and the outer ring, and the outer sleeve ring and the inner sleeve ring can also effectively protect the balls, avoiding direct contact between external impacts and the balls, thereby effectively blocking some relatively large impurities from contacting the balls, and thus ensuring the stability of the use of the deep groove ball bearing.

The installation sleeve and external components can be fixed through the locking rod on the installation sleeve. At the same time, an extension plate is fixed on the outer installation block, and the extension plate and external components can be fixed through the installation rod on the extension plate. In this way, the irreversible installation methods such as traditional welding are replaced, improving the convenience and flexibility of the installation of the deep groove ball bearing.

Outer fixing rings 4 and inner fixing rings 5 are respectively fixedly connected to the outer surfaces of the outer ring 1 and the inner ring 2. Inner sleeve rings 11 and outer sleeve rings 10 are respectively fixedly installed on the outer surfaces of the outer fixing rings 4 and the inner fixing rings 5. The inner sleeve rings 11 and the outer sleeve rings 10 are stacked at intervals, and the cross-sections of the inner sleeve rings 11 and the outer sleeve rings 10 are both in an S-shaped structure;

[0025] The inner fixing ring 5, the outer sleeve ring 10 and the inner ring 2 are fixed through the inner mounting block 12 and the tightening rod 18. The outer fixing ring 4, the inner sleeve ring 11 and the outer ring 1 are fixed through the outer mounting block 13 and the fixed rod 16. The outer sleeve rings 10 with an S-shaped cross-section and the inner sleeve rings 11 are stacked at intervals. The outer sleeve rings 10 and the inner sleeve rings 11 move respectively following the inner ring 2 and the outer ring 1, and the inner sleeve rings 11 and the outer sleeve rings 10 do not come into contact during the movement. In this way, without affecting the movement of the outer ring 1 and the inner ring 2, the long channels between the inner sleeve rings 11 and the outer sleeve rings 10 can effectively prevent dust between the inner ring 2 and the outer ring 1, and the outer sleeve rings 10 and the inner sleeve rings 11 can also effectively protect the balls 6, avoiding direct contact of external impacts with the balls 6, thereby effectively blocking some relatively large impurities from contacting the balls 6, and thus ensuring the stability of the use of the deep groove ball bearing.
