Document Type and Number:
Japanese Patent JP2951401
Kind Code:
B2
Abstract:
The sealed tapered roller bearing assembly (10, 111, 211, 311) of the present invention comprises a bearing assembly (10, 111, 211, 311) which may be removed or serviced without destroying or damaging the assembly (10, 111, 211, 311). Inner and outer races (30, 40) contain tapered rollers (60) therebetween, and a positioning ring (70) is disposed intimately about the outer race (40) as a result of the outer race (40) and ring (70) being pressfitted together. The ring (70) extends from an axial portion (76) to a radial portion (78) which becomes an angled feed tapered section (80) that extends into a first end member axial part (82). The tapered section (80), axial part (82) and a dam seal (90) define a lubricant dam area (100) about a first end of a space (95) between the races (30, 40). A second end of the space (95) between the races (30, 40) is enclosed by a composite seal member (120, 121, 221, 321) that has a first resilient foot, end, portion, or arm (124, 125, 214, 312) engaging an axial extension (72) of the axial portion (76) of the ring (70), and a second resilient foot or lip (126, 126A, 224, 324) engaging the inner race (30). For service or inspection, the entire bearing assembly (10, 111, 211, 311) may be removed easily, or just part of the bearing assembly may be removed, all without damaging or destroying the assembly (10, 111, 211, 311).
