摘要： PROBLEM TO BE SOLVED: To provide a seal structure having reduced sliding resistance and maintaining the seal performance for a long period of time.SOLUTION: The seal structure 20 includes: an inner seal ring 23 having a ridge part 22 on its outer peripheral part 21, provided on an inner race 11; an outer seal ring 27 having a groove part 26 on its inner peripheral part 25 arranged to oppose to the ridge part 22 keeping a predetermined gap therefrom, provided on an outer race 12; and grease 29 sealed in a grease reservoir 28 formed between the ridge part 22 and the groove part 26. The outer seal ring does not contact the inner seal ring. Only shearing resistance of the grease generates during rotation. The shearing resistance of the grease is significantly small than a conventional lip-slinger sliding resistance. Since the outer seal ring does not contact the inner seal ring, the sealing performance can be maintained in a good state for a long period of time.
摘要翻译：要解决的问题：提供具有降低的滑动阻力并长时间保持密封性能的密封结构。解决方案：密封结构20包括：内密封环23，其在其外周部分21上具有设置在内座圈11上的脊部22; 外密封环27，其内周部25上设置有与设置在外圈12上的预定间隙的脊部22相对的槽部26; 以及密封在形成在脊部22和槽部26之间的油脂容器28内的润滑脂29.外密封环不与内密封环接触。在旋转过程中只能产生润滑脂的抗剪切力。润滑脂的抗剪切性能比传统的润滑剂滑动阻力小得多。由于外密封圈不接触内密封环，所以密封性能可以长时间保持在良好状态。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a tapered roller bearing for a vehicle of a rolling stock which can be used for a long period without losing lubricity since the volume of grease kept inside the seal case is big enough and grease overspill from a step of the seal case to the outside of the seal case can be prevented. SOLUTION: Tapered roller bearings for the vehicle of the rolling stock comprise an bearing outer ring 2 and a bearing inner ring 1 placed opposite relatively rotatably arranged, a tapered roller 3 incorporated between the outer ring 2 and the inner ring 1, a retainer 4 of a cage-type holding the tapered roller 3 in the equal intervals and an annular seal case 8 fixed to the outer ring large-diameter side end portion 2b. The seal case 8 is lengthened by having the step 8b which has a diameter smaller than the inner diameter of the fixed end portion 8a in the outside direction of the bearing from the fixed end portion 8a fixed in the outer ring large-diameter side end portion 2b and at the same time, in the step 8b the seal 7 to seal the bearing inside is internally fitted and the inner diameter dimension d1 of the step 8b is smaller than the inner diameter dimension d2 of the large diameter side end portion 4b of the cage-type retainer 4.

摘要： PROBLEM TO BE SOLVED: To secure lubrication performance for a long time so as to realize lower torque even where a less quantity of grease is charged in a bearing.
SOLUTION: Part of a core metal 17 is covered with a seal part 32 comprising an elastic member to compose this sealing plate for a rolling bearing. The core metal 17 forms a grease sump 23. Grease applied to the grease sump part 23 due to centrifugal force generated during rotation of the bearing gradually flows out into the bearing to reach a raceway surface or a retainer pocket, thereby lubrication performance can be secured for a long time.

摘要： PROBLEM TO BE SOLVED: To provide a grease filling structure, and bearing lids, by which a life of a bearing can be elongated by effectively utilizing the grease stored in a filling chamber. SOLUTION: An annular filling chamber 12d is formed along the space between the outer race and the inner race of the bearing. An outer filling chamber 12e is extensively formed at the outside of the annular filling chamber 12d. The outer filling chamber 12e is formed along the annular filling chamber 12d and is connected to the annular filling chamber 12d over almost the whole periphery of the annular filling chamber 12d except the parts where supporting parts 12f are formed. Consequently, the contact area of the outer filling chamber 12e and the annular filling chamber 12d increases, and the movement of the base oil of the grease is promoted and the total amount of the grease existing within a filling chamber 12a can be effectively used. As a result, the lubricating durability can be elongated and also the maintenance work, etc. can be reduced because of the elongation of grease changing time. COPYRIGHT: (C)2004,JPO
