A baffle is fixedly connected at the first groove, the baffle covers the gap between the inner ring and the outer ring, and the other end is placed at the second groove. A sealing gasket is arranged at the other end of the baffle.

[0006] A further improvement of the bearing sealing structure and the bearing of the utility model is that one end edge of the upper end face of the baffle away from the first groove is provided with a first fixing groove downward, a second fixing groove is provided at the corresponding position of the second groove, and an auxiliary baffle is fixedly connected at the second fixing groove, and the other end of the auxiliary baffle is close to the first fixing groove.

[0007] A further improvement of the bearing sealing structure and the bearing of the utility model is that the sealing gasket is arranged on the groove wall of the first fixing groove away from the auxiliary baffle.

[0008] A further improvement of the bearing sealing structure and the bearing of the utility model is that a positioning groove is arranged at one end of the baffle close to the inner ring on the side close to the balls, there is a spacing between the positioning groove and the second groove, and an auxiliary sealing gasket is arranged on the positioning groove.

[0009] A further improvement of the bearing sealing structure and the bearing of the utility model is that one end of the auxiliary sealing gasket away from the second groove is obliquely arranged and extends into the spacing.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model grooves the outer surfaces of the inner and outer rings of the bearing, and then arranges baffles and sealing gaskets, which ensures the sealing effect and is convenient for installation; on the other hand, the sealing gasket contacts the inner ring to achieve dustproof sealing, and the sealing effect is improved by setting two sets of sealing structures.

[0014] In the figure: 1 inner ring, 2 outer ring, 3 first groove, 4 second groove, 5 baffle, 6 first fixed groove, 7 second fixed groove, 8 auxiliary baffle, 9 sealing gasket, 10 auxiliary sealing gasket, 11 positioning groove. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 and Figure 2 As shown, a bearing sealing structure and a bearing, comprising an inner ring 1, an outer ring 2 and balls arranged between the inner ring and the outer ring, the above structure is one of the conventional structures of existing bearings. Furthermore, the upper and lower end surfaces of the outer ring are provided with first grooves 3 downwardly and upwardly at one side edge close to the inner ring, that is, the cross-section of one end of the upper and lower end surfaces of the outer ring close to the inner ring is L-shaped. The upper and lower end surfaces of the inner ring are provided with second grooves 4 downwardly and upwardly at one side edge close to the outer ring. A baffle 5 is fixedly connected to the first groove, and the connection method can be achieved by bolt connection, specifically, the tow rod bolts are arranged circumferentially. The baffle covers the gap between the inner ring and the outer ring, and the baffle is preferably annular. The other end is placed in the second groove, and a sealing gasket is provided at the other end of the baffle.

[0017] Furthermore, a first fixing groove 6 is provided downwardly at one end edge of the upper end surface of the baffle away from the first groove, a second fixing groove 7 is provided at a position corresponding to the second groove, an auxiliary baffle 8 is fixedly connected to the second fixing groove, and the other end of the auxiliary baffle is close to the first fixing groove. The connection method between the auxiliary baffle and the inner ring can also be a bolt-tightening connection.

[0018] The gasket is disposed on the groove wall of the first fixing groove away from the auxiliary baffle. A primary seal is achieved.
