摘要： PROBLEM TO BE SOLVED: To provide a roller bearing sealing device, capable of preventing rust from remaining in a filter of the sealing device by preventing the entry of moisture into a vent hole of the sealing device.SOLUTION: The sealing device 6 includes an annular seal case 11 fixed to the end of an outer ring 2, and an annular seal body 12 having a base end fixed to the peripheral surface of the seal case 11 and a front end contacting an inner ring 1 to seal a bearing space. The seal case 11 has a communication hole 15 to be communicated with the inside/outside of the bearing, and the communication hole 15 has the filter 16 gas-permeable for interrupting moisture and oil. Besides, an annular recess Kh is provided around the communication hole 15 in a surface 11b of the seal case 11 where the communication hole 15 is opened.

摘要： PROBLEM TO BE SOLVED: To provide a tapered roller bearing whose outer ring can be produced at low cost, and a mounting structure therefor.SOLUTION: An outer ring 5 of a tapered roller bearing 1 is formed by press working of a steel sheet. As a result, conventional cutting working when producing an outer ring is no longer necessary, and therefore, the production cost of the outer ring 5 is reduced and at the same time, the tapered roller bearing 1 can be easily mounted in a housing 2 by providing a flange part 11 at the large-diameter end part and a direct cylinder part 12 at the small-diameter end part of the outer ring 5 and causing the flange part 11 and the direct cylinder part 12 of the outer ring 5 to engage with the housing 2 having an inner peripheral shape corresponding to the outer peripheral shape of the outer ring 5.
摘要翻译：要解决的问题：提供一种可以以低成本生产外圈的圆锥滚子轴承及其安装结构。解决方案：通过钢板的冲压加工形成圆锥滚子轴承1的外圈5。结果，不再需要在制造外圈时的常规的切割加工，因此，外圈5的制造成本降低，同时圆锥滚子轴承1可以容易地安装在壳体2中在大直径端部处设置凸缘部11，在外圈5的小直径端部设有直接圆筒部12，使外圈5的凸缘部11和直接圆筒部12与壳体2具有与外圈5的外周形状相对应的内周形状。版权所有（C）2013，JPO＆INPIT
