Abstract

The utility model discloses a bearing device which comprises a bearing seat, a bearing, a main shaft and a sealing ring, wherein the sealing ring comprises a sealing piece and a steel framework which is wrapped inside the sealing piece; sealing lips protecting lips are arranged on the sealing piece; the sealing lips are pressed on the main shaft through a spring; the protecting lips are in interference fit with the main shaft. According to the bearing device, by pressing the sealing lips on the main shaft, a lubricant is effectively prevented from leaking off; through the interference fit of the protecting lips and the main shaft, the invasion of external impurities and dust is effectively prevented.

Description

A kind of bearing means
Technical field
The utility model discloses a kind of bearing means.
Background technique
The bearing means of present employing oil lubrication, prevent that by compression fit and sealing lip and main shaft interference fit between seal ring and the bearing support oiling agent from leaking, effect is bad, when vibration is big, can make sealing lip and main shaft cooperation place loosening, easily cause oiling agent to external leakage, sealing lip is inwardly installed simultaneously, only can avoid oiling agent to leak, the intrusion of extraneous dust impurity can't be prevented, present user can't be adapted to the requirement of bearing waterproof and dustproof, leakproof.
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, bearing, main shaft and seal ring; described seal ring comprises Sealing and is wrapped in the Steel Skeleton of Sealing inside; described Sealing is provided with sealing lip and protection lip; described sealing lip is pressed on the main shaft by spring, described protection lip and main shaft interference fit.
The beneficial effects of the utility model are: by spring sealing lip is pressed on the main shaft, can prevents effectively that oiling agent from leaking; By protection lip and main shaft interference fit, can effectively prevent the intrusion of extraneous impurity dust.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged view at A place among Fig. 1.
Among the figure: bearing support 1, bearing 2, main shaft 3, seal ring 4, Sealing 41, sealing lip 411, protection lip 412, Steel Skeleton 42, spring 5.
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 and Figure 2; a kind of bearing means; comprise bearing support 1, bearing 2, main shaft 3 and seal ring 4; described seal ring 4 comprises Sealing 41 and is wrapped in the Steel Skeleton 42 of Sealing 41 inside; described Sealing 41 is provided with sealing lip 411 and protection lip 412; described sealing lip 411 is pressed on the main shaft 3 by spring 5, described protection lip 412 and main shaft 3 interference fit.
Seal ring 4 is crimped on the bearing support 1, the lip of sealing lip 411 is inwardly installed, and by spring 5 sealing lip 411 is pressed on the main shaft 3, produces vibration in main shaft 3 operation process, by the spring 5 flexible impacting forces that produce sealing lip 411 is fastened on the main shaft 3 all the time, can prevents effectively that oiling agent from leaking.The lip of protection lip 412 is outwards installed, and with main shaft 3 interference fit, can effectively prevent the intrusion of extraneous impurity dust.
