Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and the specific embodiments.
The utility model relates to a sealed guide roller assembly structure, which comprises an outer end cover 1 fixed on a bearing seat 2 and a spacer bush 5 arranged between a bearing 3 and an inner end cover 4; the bearing inner ring on the bearing seat 2 is fixed through a pressing plate 8; the inner end cover I4 is connected with the outer end cover I1 through a fastener 6, and the inner end cover I4 is clamped at the axle diameter spigot of the roller 10; the connection structure of the two ends of the roller 10 is the same. Wherein, the connection structure of the two ends of the roller 10 is the same, one end is provided with an inner end cover I4 and an outer end cover I1, and the other end is provided with an inner end cover II 11 and an outer end cover II 7. The spacer bush 5, the first inner end cover 4 and the second inner end cover 11 form a labyrinth structure. The side of the bearing seat 2 is provided with a nozzle tip 12. The fastener 6 consists of a hexagonal bolt, a hexagonal nut, a flat washer and a light spring washer. The pressing plate 8 is fixed by bolts 9, and the bolts 9 are hexagonal bolts.
When the novel bearing is used, the first outer end cover 1 is fixed on the bearing seat 2 through bolts, the spacer bush 5 is arranged between the bearing 3 and the first inner end cover 4 and forms a labyrinth form with the first inner end cover 4, the first outer end cover 1 and the first inner end cover 4 are fixedly connected through bolts, the first inner end cover 4 is clamped at the position of a roller shaft diameter spigot, the bearing inner ring is fixed through the shaft end pressing plate 8, and the installation modes of the left end and the right end are consistent. The sealed oil cavity is realized by utilizing the sealing cover of the bearing seat 2 and a group of labyrinth combined seals at the roller diameter part; the side surface of the bearing seat 2 is drilled and communicated with the oil cavity, and a glib 12 with a unidirectional function is arranged. The labyrinth seal type is provided to replace rubber seal, so that the effect of rubber seal can be achieved, and the influence of temperature can be reduced.
