DETAILED DESCRIPTION

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a single-row angular contact ball bearing with stable installation, such as Figure 1-3 As shown, it includes a bearing body 1, which includes an outer ring 101, an inner ring 102 and a sphere 103. The sphere 103 is installed between the outer ring 101 and the inner ring 102. The top of the inner ring 102 is set to be a notch, and a limit block 2 is installed at the notch. The left and right ends of the limit block 2 are connected with mounting plates 3. The mounting plate 3 is installed on the side of the inner ring 102 by bolts 4. The lower side of the limit block 2 is connected with a fastening ring 5. The fastening ring 5 is located on the inner side of the inner ring 102. The upper end of the fastening ring 5 is connected to a limit sleeve 6. The left and right sides of the positioning sleeve 6 are connected with positioning rings 7. By setting a limit block 2, the limit block 2 is located at the notch of the inner ring 102. When the bearing body 1 needs to be disassembled, the bolts 4 on the surface of the mounting plate 3 can be unscrewed, and then the limit block 2 can be removed. At this time, the notch of the inner ring 102 can be facing downward, and the balls 103 can be taken out from the notch one by one. The device can make the overall disassembly and assembly of the bearing body 1 more labor-saving through the setting of the limit block 2, and will not cause wear to the parts of the bearing body 1, thereby increasing the service life of the bearing body 1.

[0023] The limiting sleeve 6 and the positioning ring 7 are respectively sleeved on the outside of each ball 103, and the positioning rings 7 are connected by a bracket 8. The limiting sleeve 6 and the positioning ring 7 can be used to position the ball 103 to prevent the ball 103 from rolling randomly and causing the bearing body 1 to get stuck or disintegrate.

[0024] The limit block 2 is of a splicing type, and the limit blocks 2 are respectively located on the front and rear sides of the inner ring 102. The limit sleeve 6 and the positioning ring 7 are semi-arc-shaped and are provided in two groups. The two groups of limit sleeves 6 are respectively located on the top of the two groups of limit blocks 2. By setting the limit block 2 to a splicing type, the normal disassembly and assembly of the bearing body 1 can be met.

[0025] Positioning plates 9 are installed in a circular array on the outside of the fastening ring 5, and positioning grooves corresponding to the positioning plates 9 are opened on the side of the inner ring 102. By providing the positioning plates 9, the positioning plates 9 can position the fastening ring 5 to improve the stability of its connection.

[0026] A reinforcement plate 10 is installed at the bottom of the fastening ring 5. The reinforcement plate 10 is located directly below the limit block 2 and is installed by bolts 4. The reinforcement plate 10 is connected to one set of limit sleeves 6. By providing the reinforcement plate 10, the reinforcement plate 10 can prevent the lower side of the fastening ring 5 from detaching from the inner ring 102, thereby improving the stability of the fastening ring 5.

[0027] A collar 11 is installed on the side of the fastening ring 5, and a fastening plate 12 is installed in a circular array on the inner side of the collar 11. The fastening ring 5 is sleeved on the outside of the shaft body. By providing the collar 11 and the fastening plate 12, the fastening plate 12 can firmly grasp the surface of the shaft body, thereby improving the stability of the connection between the bearing body 1 and the shaft body.

[0028] There is a gap between the limiting sleeve 6, the positioning ring 7 and the ball 103. This arrangement can prevent the excessive friction of the ball from reducing the service life of the bearing body 1.

[0029] An oil retaining ring is installed on the inner side of the positioning ring 7, and this arrangement can prevent the lubricating oil in the bearing body 1 from leaking out.
