【考案が解決しようとする課題】[Problems to be solved by the device]

上記従来技術にあっては、保持器の外側にシ−ル体を取り付けているので、そ の分だけ軸方向スペ−スを必要とし軸受巾が増大するという問題点があった。 In the above prior art, since the seal body is attached to the outside of the cage, there is a problem in that the axial space is required by that amount and the bearing width increases.

【０００４】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は上記問題点を解決することを目的とし、内輪、外輪、円錐ころ、保持 器、シ−ル体よりなる円錐ころ軸受であって、少なくとも内輪小径側のシ−ル体 は保持器端部に一体的に設けられていることを特徴とする。 The present invention is intended to solve the above problems, and is a tapered roller bearing including an inner ring, an outer ring, a tapered roller, a cage, and a seal body, in which at least the seal body on the inner ring small diameter side has a cage end. It is characterized in that it is provided integrally with the section.

【実施例】【Example】

図１は本考案の第１実施例である。１は円錐ころ、２はその保持器、３は内輪 、４は外輪で、保持器２小径側外側面に芯金５をカシメにより一体に固定し、該 芯金５の上下端にシ−ル体６，７を取り付け、その外周部を内輪３、外輪４に接 触させている。 FIG. 1 shows a first embodiment of the present invention. Reference numeral 1 is a tapered roller, 2 is a retainer thereof, 3 is an inner ring, and 4 is an outer ring. The bodies 6 and 7 are attached, and their outer peripheral portions are in contact with the inner ring 3 and the outer ring 4.

【０００６】 図２は本考案の第２実施例である。円錐ころ１の保持器２の小径側外側面に芯 金８をリベット９により一体に固定し、該芯金８の上下端にシ−ル体１０，１１ を取り付け、その外周部を内輪３、外輪４に接触させている。FIG. 2 shows a second embodiment of the present invention. A cored bar 8 is integrally fixed to the outer surface of the tapered roller 1 on the small diameter side of the cage 2 by rivets 9, and seal bodies 10 and 11 are attached to the upper and lower ends of the cored bar 8, the outer peripheral portion of which is the inner ring 3, It is in contact with the outer ring 4.

【０００７】 図３は本考案の第３実施例である。円錐ころ１の保持器２の小径側外側面にシ −ル体１２の中間部を焼付け固定し、その上下端を内輪３、外輪４に接触させて いる。 図４は大径側の第１実施例で図７に示した従来例と同様構造である。 図５は大径側の第２実施例で保持器２の大径側上面及び下面にシ−ル体３０の 中間部を焼付け固定し、その上下端を外輪４及び内輪３に接触している。 図６は大径側の第３実施例で、保持器２にシ−ル体３１を圧入している。大径 側は上記各実施例何れを用いてもよい。図５、図６の実施例の如くシ−ル体を保 持器に取り付けると、軸方向の長さを更に短縮できる。FIG. 3 shows a third embodiment of the present invention. The intermediate portion of the seal body 12 is baked and fixed to the outer surface of the tapered roller 1 on the small diameter side of the cage 2, and the upper and lower ends thereof are in contact with the inner ring 3 and the outer ring 4. FIG. 4 shows the same structure as the conventional example shown in FIG. 7 in the first embodiment on the large diameter side. FIG. 5 shows the second embodiment of the large diameter side, in which the middle portion of the seal body 30 is baked and fixed to the upper and lower surfaces of the cage 2 on the large diameter side, and the upper and lower ends thereof are in contact with the outer ring 4 and the inner ring 3. . FIG. 6 shows a third embodiment on the large diameter side, in which a seal body 31 is press-fitted into the cage 2. Any of the above embodiments may be used for the large diameter side. When the seal body is attached to the retainer as in the embodiment of FIGS. 5 and 6, the axial length can be further shortened.

【考案の効果】[Effect of device]

本考案によると、内輪、外輪、円錐ころ、保持器、シ−ル体よりなる円錐ころ 軸受であって、少なくとも内輪小径側のシ−ル体は保持器端部に一体的に設けら れているので、軸方向スペ−スが少なくなり軸受巾を減少させることができる。 According to the present invention, there is provided a tapered roller bearing including an inner ring, an outer ring, a tapered roller, a retainer, and a seal body, and at least the seal body on the smaller diameter side of the inner ring is integrally provided at the end of the retainer. Therefore, the space in the axial direction is reduced and the bearing width can be reduced.
