SUPPORT RING OF RAILWAY BEARING Russian patent published in 2014 - IPC F16C19/38 F16C33/76 F16C35/63 B61F15/22 

FIELD: machine building.

SUBSTANCE: in general, invention relates to antifriction bearings, namely, as per one design version to tapered roller bearings. A bearing assembly includes an outer bearing race (31), an inner bearing race (40), many rollers (44), an inner seal housing (56), an outer seal housing (54), a support ring (22) and an adhesive gasket (90). The outer race (31) is fitted by a raceway turned radially inside. The inner race (40) is mounted on a centre shaft (12). All the many rollers (44) are set between the raceway of the outer race (31) and the inner race (40). The inner seal housing (56) is attached to the inner race (40). The outer seal housing (54) is attached to the outer race (31) and is fitted by a leakproof casing running to the inner seal housing (56). The supporting ring (22) is attached to a fillet (18) of the centre shaft (12) and rests against the inner race (40). The supporting ring (22) comprises an annular boss (23) protruding outside in the axial direction and resting against the inner race (40). The supporting ring (22) and the inner race (40) form a gap radially outside the boss (23) with the adhesive gasket (90) set in the gap. The adhesive gasket (90) is set between the supporting ring (22) and the inner race (40). The adhesive gasket (90) serves for the attachment of the supporting ring (22) to the inner race (40). Method for forced fitting of the bearing assembly and the supporting ring on a shaft is proposed as well.

EFFECT: due to the installation of an adhesive gasket it is provided for easier forced fitting of a bearing assembly and a supporting ring as a solid unit onto a centre shaft by one operation, compression preloading of the bearing unit is kept at the bearing assembly regardless of any deterioration of gasket properties.
