Abstract

The utility model discloses a bearing device, comprising a bearing seat, a bearing arranged in the bearing seat, a main shaft and a bearing ring, wherein the bearing seat is provided with a first groove and a second groove, the bearing ring is fixedly arranged on the main shaft through a screw and is provided with a protruded part, the protruded part is arranged in the first groove, the second groove is internally provided with a felt ring which is in contact fit with the main shaft, the bearing seat, the main shaft and the bearing are matched to form a maze which is internally provided with a V-shaped sealing ring, one side of the V-shaped sealing ring is locked by the bearing ring, and a sealing lip is arranged on the V-shaped sealing ring and is in interference fit with the end part of the bearing seat. Due to the arrangement of the maze, the V-shaped sealing ring and the felt ring, the sealing effect is good.

Description

A kind of bearing means

Technical field

The utility model discloses a kind of bearing means.

Background technique

Bearing self on some present bearing means is not established seal ring, the formation clearance seal that only depends on main shaft to cooperate with bearing support, a labyrinth seal passage namely is set between main shaft and bearing support, can satisfy general seal request, but under the heavily contaminated operating mode, this seal form is unsatisfactory for keeping out the environmental contaminants aspect, and the user is more and more higher to the performance requirement dustproof, waterproof of bearing means.

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 of good sealing effect is provided.

For achieving the above object, the technical solution of the utility model is: a kind of bearing means, comprise bearing support, be loaded on the bearing in the bearing support, main shaft and bearing ring, described bearing support is provided with first groove and second groove, described bearing ring is fixed on the main shaft by screw, outstanding position is arranged on the bearing ring, described protuberance position is in first groove, in described second groove felt circle is housed, described felt circle contacts cooperation with main shaft, described bearing support, main shaft and bearing ring cooperate the formation labyrinth, be provided with a V-shaped seal ring in the labyrinth, described V-shaped seal ring one side is locked by bearing ring, and a sealing lip is arranged on the V-shaped seal ring, described sealing lip and bearing support end interference fit.

The beneficial effects of the utility model are: by the setting of labyrinth, V-shaped seal ring and felt circle, good sealing effect.

Description of drawings

Fig. 1 is schematic representation of the present utility model;

Fig. 2 is the enlarged view at A place among Fig. 1.

Among the figure: bearing support 1, first groove 11, second groove 12, bearing 2, main shaft 3, bearing ring 4, outstanding position 41, screw 5, V-shaped seal ring 6, sealing lip 61, felt circle 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 Fig. 1, shown in Figure 2, a kind of bearing means, comprise bearing support 1, be loaded on the bearing 2 in the bearing support 1, main shaft 3 and bearing ring 4, described bearing support 1 is provided with first groove 11 and second groove 12, described bearing ring 4 is fixed on the main shaft 3 by screw 5, outstanding position 41 is arranged on the bearing ring 4, described outstanding position 41 places in first groove 11, in described second groove 12 felt circle 7 is housed, described felt circle 7 contacts cooperation with main shaft 3, described bearing support 1, main shaft 3 and bearing ring 4 cooperate the formation labyrinth, be provided with a V-shaped seal ring 6 in the labyrinth, described V-shaped seal ring 6 one sides have a sealing lip 61 by bearing ring 4 lockings on the V-shaped seal ring 6, described sealing lip 61 and bearing support 1 end interference fit.

In main shaft 3 operation process, bearing ring 4, V-shaped seal ring 6 and felt circle 7 are with main shaft 3 rotations, setting by the labyrinth, with most of environmental contaminants retaining externally, V-shaped seal ring 6 one sides are by bearing ring 4 lockings, and opposite side is by sealing lip 61 and bearing support 1 end interference fit, small amounts of contamination is hindered by V-shaped seal ring 6 after breaking through the labyrinth, even if still have the minute quantity pollutant to break through V-shaped seal ring 6, also can be hampered by felt circle 7, whole device sealing effect is very good.

Claims
