Detailed Description

The technical solutions in the present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses a bearing with high reliability. Referring to fig. 1 and 2, a highly reliable bearing includes an outer ring 11, an inner ring 12 disposed inside the outer ring 11, a cage 13 disposed between the outer ring 11 and the inner ring 12, and rolling elements 14 disposed on the cage 13. The rolling bodies 14 abut against the outer ring 11 and the inner ring 12, respectively, so that relative rotation can occur between the outer ring 11 and the inner ring 12. A bearing cap 15 is provided between the outer ring 11 and the inner ring 12, and covers the cage 13 and the rolling elements 14 inside, so that foreign matter cannot enter between the outer ring 11 and the inner ring 12.

Referring to fig. 2 and 3, an outer side of the bearing cap 15 is bolted to the outer ring 11, and an inner side of the bearing cap 15 is plugged into the inner ring 12, so that when the outer ring 11 rotates relative to the inner ring 12, the bearing cap 15 rotates together with the outer ring 11. The bolt connection mode is used, so that workers can conveniently detach the bearing cover 15, and lubricating oil is filled between the outer ring 11 and the inner ring 12. A flange 151 is integrally formed on the inner side of the bearing cap 15, and the flange 151 extends in a ring shape along the circumferential direction of the bearing cap 15. The inner ring 12 is provided with a slot 121 matched with the flange 151, so that the flange 151 can be inserted into the slot 121. The insertion groove 121 is opened in a complete annular shape along the circumferential direction of the inner ring 12.

The staff can more conveniently pull down bearing cap 15 from the bearing, scribble lubricating oil to holder 13 and rolling element 14, can significantly reduce the friction between rolling element 14 and outer lane 11 and inner circle 12 to the life of bearing has been promoted.

Referring to fig. 4, a first protrusion 122 is integrally formed in the slot 121 on the inner ring 12, and the first protrusion 122 is located at a position of the slot 121 far from the bottom of the slot. The first protrusion 122 extends along the insertion groove 121 in a complete ring shape. The groove 1511 is formed in the turned-over edge 151, so that when the turned-over edge 151 is inserted into the slot 121, the first protruding portion 122 can be clamped in the groove 1511, the turned-over edge 151 is limited, and the turned-over edge 151 is not prone to being separated from the slot 121.

Referring to fig. 4, in order to further improve the sealing performance between the inner ring 12 and the bearing cap 15, a second convex portion 1512 is integrally formed on the flange 151. A gap for accommodating the second protruding portion 1512 is formed between the first protruding portion 122 and the bottom of the slot 121, so that when the flange 151 is inserted into the slot 121, the second protruding portion 1512 can abut against the first protruding portion 122, thereby preventing the flange 151 from coming out of the slot 121. On the other hand, when the turned edge 151 is inserted into the slot 121, the tightness of the connection between the bearing cover 15 and the inner ring 12 can be further improved, so that external impurities are not easy to enter between the inner ring 12 and the outer ring 11, and the service life of the bearing is prolonged.

Referring to fig. 2, a plurality of threaded holes are uniformly formed in the outer ring 11 along the circumferential direction, and fastening bolts 2 are screwed into the threaded holes. Connecting holes for the fastening bolts 2 to pass through are formed in the bearing cover 15, and the number of the connecting holes is the same as that of the threaded holes and corresponds to that of the threaded holes one by one, so that the fastening bolts 2 tightly press the bearing cover 15 on the outer ring 11.

Referring to fig. 2 and fig. 3, the connection hole is a countersunk hole, and the fastening bolt 2 is a hexagon socket head cap bolt, so that the fastening bolt 2 is flush with the surface of the bearing cap 15 after being fastened, and the surface of the bearing cap 15 is more flat and has no protrusions.

Referring to fig. 2, in order to facilitate the installation of the bearing cap 15, the positioning groove 111 is formed in the outer ring 11, and the positioning block 152 is integrally formed on the bearing cap 15, so that when the positioning block 152 is clamped in the positioning groove 111, the threaded hole in the outer ring 11 is aligned with the connecting hole in the bearing cap 15, thereby facilitating the installation of the fastening bolt 2 by a worker and reducing the installation difficulty.

Referring to fig. 3 and 4, in order to improve the sealing between the bearing cover 15 and the outer ring 11 and the inner ring 12, a seal pad 153 is fixedly disposed on one side of the bearing cover 15 close to the inner ring 12 and the outer ring 11. In some implementations, the gasket layer 153 is rubber. The seal cushion layer 153 can better block external sundries, so that the inner ring 12 and the outer ring 11 are kept clean, and the rolling bodies 14 are prevented from being abraded greatly by the sundries.

Referring to fig. 2 and 3, a first receiving groove 112 and a second receiving groove 123 for receiving the bearing cap 15 are respectively formed in the outer ring 11 and the inner ring 12, and the first receiving groove 112 and the second receiving groove 123 together form an area for receiving the bearing cap 15, so as to perform a certain positioning function and a certain limiting function on the bearing cap 15. Meanwhile, when the bearing cap 15 is mounted on the outer ring 11 and the inner ring 12, the surface of the bearing cap 15 is flush with the surfaces of the outer ring 11 and the inner ring 12.

The implementation principle of the embodiment of the application is as follows: in the using process of the bearing, the bearing is maintained in time. After the bearing cover 15 is detached from the outer ring 11 and the inner ring 12, lubricating oil is applied to the rolling elements 14, so that friction between the rolling elements 14 and the inner ring 12 and the outer ring 11 is smaller, wear on the bearing is smaller, and the service life of the bearing is longer. Meanwhile, under the protection of the bearing cover 15, external impurities are more difficult to enter between the inner ring 12 and the outer ring 11.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
