SEALING DEVICE FOR THRUST-BEARING OF ROLLING Russian patent published in 2018 - IPC F16C33/76 F16C43/04 

FIELD: machine engineering.

SUBSTANCE: invention relates to a sealing device (14a) on a thrust bearing (10), which consists of two rotating rings (12, 13) between which the rolling elements (4) are disposed. The sealing device (14a) seals the space (16) of the thrust bearing (10). The sealing device (14a) comprises, as a reinforcement, a rigid sleeve (15a, 15b, 15c) symmetrical about the axis of rotation, which surrounds both rotating rings (12, 13) on the outside. The sealing device (14a, 14b, 14c) is fixed by at least one mounting portion (20a, 20b, 20c). Rigid sleeve (15a, 15b, 15 c) has with its hand pointing in the direction of rotating rings (12, 13), compacted plots (19a, 19b) and forms a continuous connection with elastic sealing material (17), at least on the sealing portions (19a, 19b). Rigid sleeve (15a, 15b) is located around or partially stabilizing area (18), which acts on an axis in the space rolling bearing (16) and forms the first sealing portion (19a) from the sealing portions (19a, 19b) with respect to the axially inner wall (21) of the first rotating ring (12) of both rotating rings (12, 13). Provided from the plot (18) and based on different rotating ring (13) the working edge of the seal (22) of the material (17), which forms the second sealing portion (19b) from sealing portions (19a, 19b). A suspension of a vehicle with a thrust bearing (10) and an axle with controllable vehicle wheels containing such a suspension are also claimed.

EFFECT: development of an optimized, compact design for a thrust bearing assembly that is simple and has an improved retention function and high compaction quality, and which is inexpensive to manufacture.
