Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The embodiment discloses a bearing sealing structure, as shown in fig. 1 to 4, the utility model has good sealing effect and oil leakage prevention effect; comprises an inner ring 1, an outer ring 2 and a retainer 3; the inner ring 1 is arranged on the innermost layer; the outer ring 2 is arranged on the outer layer; a retainer 3 is arranged between the inner ring 1 and the outer ring 2; the retainer 3 is provided with rolling bodies 4; a first sealing part 5 and a second sealing part 6 are arranged between the inner ring 1 and the outer ring 2; the first closing part and the second closing part 6 are made of rubber.
By adopting the technical scheme: the cage 3 serves to isolate the rolling bodies 4, typically also guide and retain the rolling bodies 4 in the bearing so that the cage 3 is firmly arranged between the inner ring 1 and the outer ring 2; the first and second closing portions 5, 6 are capable of closing the bearing such that the bearing seals and the first and second closing portions 5, 6 prevent lubricating oil from leaking out of the bearing.
The outer ring 2 is provided with a connecting groove 7; one side of the first sealing part 5 is adhered to the connecting groove 7; a gap is arranged between the other side of the first closing part 5 and the inner ring 1.
By adopting the technical scheme: one side of the first sealing part 5 is adhered to the connecting groove 7, so that the connection between one side of the first sealing part 5 and the connecting groove 7 is stable; a gap is formed between the other side of the first closing part 5 and the inner ring 1, so that the inner ring 1 can rotate and the gap is very small.
The inner ring 1 is fixedly connected with a second sealing part 6; one side of the second sealing part 6 is fixedly connected with the inner ring 1; a gap is formed between the other side of the second sealing part 6 and the first sealing part 5.
By adopting the technical scheme: one side of the second sealing part 6 is fixedly connected with the inner ring 1, and a gap is formed between the other side of the second sealing part and the first sealing part 5, so that the second sealing part 6 can be prevented from contacting the first sealing part 5 when the inner ring 1 rotates; the gap is an extremely fine gap.
