Abstract

The utility model discloses a bearing assembly which comprises a bearing carrier, a bearing installed in the bearing carrier, and a main shaft, wherein the main shaft is matched with a bearing ring; one side of the bearing ring abuts against the bearing inner ring, and the other side is locked with the main shaft through a locking nut; the bearing ring is provided with a groove; the bearing carrier is provided with a convex ring; the convex ring and the groove are matched to form a labyrinth; the bearing carrier is provided with a lubricating nipple and a lubricating hole; the lubricating nipple is connected with the lubricating hole; and the lubricating hole is communicated with the labyrinth. The labyrinth formed by matching the groove on the bearing ring and the convex ring of the bearing carrier, and the lubricating hole and the lubricating nipple communicated with the labyrinth are arranged, so the bearing assembly has favorable sealing effect under heavy pollution working conditions.

Description

A kind of bearing means
Technical field
The utility model discloses a kind of bearing means.
Background technique
The seal form that the main shaft of present bearing means cooperates with bearing support mainly is clearance seal, namely between main shaft and bearing support, leave a sealing slit, can satisfy general seal request, but this seal form can't be applicable to the heavily contaminated operating mode, for keeping out extraneous dust, prevent that lubricating grease leakage aspect is unsatisfactory, and the user is more and more higher to the performance requirement of the waterproof and dustproof of bearing means, leakproof fat.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of bearing means that excellent sealing effect is arranged under the heavily contaminated operating mode is provided.
For achieving the above object, the technical solution of the utility model is: a kind of bearing means, comprise bearing support, be installed on bearing and main shaft in the bearing support, be combined with bearing ring on the described main shaft, described bearing ring one side and bearing inner race offset, opposite side is by locking nut and principal shaft locking, described bearing ring is provided with groove, on the described bearing support bulge loop is arranged, bulge loop and groove complement each other to form the labyrinth, described bearing support is provided with pump nozzle and oil hole, and described pump nozzle links to each other with oil hole, and described oil hole is connected with the labyrinth.
The beneficial effects of the utility model are: labyrinth and the oil hole that is connected with the labyrinth and the setting of pump nozzle by the groove on the bearing ring and the bulge loop on the bearing support complement each other to form have good sealing effect under the heavily contaminated operating mode.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: bearing support 1, bulge loop 11, bearing 2, bearing inner race 21, main shaft 3, bearing ring 4, groove 41, locking nut 5, pump nozzle 6, oil hole 7.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of bearing means, comprise bearing support 1, be installed on bearing 2 and main shaft 3 in the bearing support 1, be combined with bearing ring 4 on the described main shaft 3, described bearing ring 4 one sides and bearing inner race 21 offset, opposite side is by locking nut 5 and main shaft 3 lockings, described bearing ring 4 is provided with groove 41, on the described bearing support 1 bulge loop 11 is arranged, bulge loop 11 complements each other to form the labyrinth with groove 41, described bearing support 1 is provided with pump nozzle 6 and oil hole 7, and described pump nozzle 6 links to each other with oil hole 7, and described oil hole 7 is connected with the labyrinth.
Under common operating mode, rely on labyrinth seal can prevent that extraneous dust impurity from entering, can prevent simultaneously the leakage of lubricating grease again, under the operating mode of heavily contaminated, can inject grease to pump nozzle 6, grease enters the labyrinth seal passage along oil hole 7, makes bearing means that good sealing effect be arranged under the heavily contaminated operating mode.
