Abstract
A bearing seal provides a first sealing member to be secured to a shoulder on one side of a first bearing ring and a second sealing member that can be secured to a shoulder on the same side of a second bearing ring. A labyrinth seal gap is formed between the first sealing member and the second sealing member, which has at least one tooth-shaped turn. On the basis of the above bearing seal, the present invention further provides a rolling bearing that employs the bearing seal on an axial side thereof.
Claims9
A bearing seal comprising:
- a first sealing member configured to be secured to a first shoulder recess on a first axial side of a first bearing ring, the first sealing member comprising a first flinger and a first seal body formed on the first flinger, and
- a second sealing member configured to be secured to a second shoulder recess on the first axial side of a second bearing ring, the second sealing member comprises a second flinger and a second seal body formed on the second flinger, wherein
- a labyrinth seal gap is formed between the first sealing member and the second sealing member, wherein
- the first flinger comprises a first axial portion which is secured into the first shoulder recess, the first axial portion having none of the first seal body formed thereon, wherein
- the second flinger comprises a second axial portion which is secured into the second shoulder recess, the second axial portion having none of the second seal body positioned between the second axial portion and the second shoulder recess, and wherein
- the first and second axial portions of the first and second flingers form a portion of the labyrinth seal gap.
A rolling bearing comprising a first bearing ring, a second bearing ring, and a bearing seal, the bearing sealing being located on a first axial side of the rolling bearing, the bearing seal comprising:
- a first sealing member configured to be secured to a first shoulder recess on the first bearing ring on the first axial side of the rolling bearing, the first sealing member comprising a first flinger and a first seal body formed on the first flinger, and
- a second sealing member configured to be secured to a second shoulder recess on the second bearing ring on the first axial side of the rolling bearing, the second sealing member comprises a second flinger and a second seal body formed on the second flinger, wherein
- a labyrinth seal gap is formed between the first sealing member and the second sealing member, wherein
- the first flinger comprises a first axial portion which is secured into the first shoulder recess, the first axial portion having none of the first seal body formed thereon, wherein
- the second flinger comprises a second axial portion which is secured into the second shoulder recess, the second axial portion having none of the second seal body positioned between the second axial portion and the second shoulder recess, and wherein
- the first and second axial portions of the first and second flingers form a portion of the labyrinth seal gap.
