Embodiment 1

[0023] Embodiment one, see figure 1 , a double-seal bearing, including an inner ring 1, an outer ring 2 sleeved on the inner ring, and a rolling element 3 located between the inner ring and the outer ring. The rolling elements 3 are rolling balls, needle rollers and rollers, etc., depending on the specific type of bearing.

[0024] The inner ring 1 is provided with an inner ring portion sealing ring 4 . The sealing ring 4 of the inner ring part is sealed and fixed together with the inner ring 1 by means of bonding. The outer peripheral surface of the inner ring seal ring 4 is in sealing contact with the inner peripheral surface of the outer ring 2 .

[0025] The outer ring 2 is provided with an outer ring portion seal ring 5 . The sealing ring 5 of the outer ring portion is sealed and fixed together with the outer ring 2 by means of bonding. The inner peripheral surface of the outer ring seal ring 5 is in sealing contact with the outer peripheral surface of the inner ring ...

Embodiment 2

[0029] Embodiment two, see image 3 , The difference with the first embodiment is that: the inner ring 1, the sealing ring 4 of the inner ring part, the outer ring 2 and the sealing ring 5 of the outer ring part form a vacuum noise isolation chamber 8. The vacuum noise isolation chamber 8 is provided with an exhaust channel 81 . The exhaust channel 81 includes a channel body 811 and an air inlet 812 . The channel body 811 is disposed on the outer sealing ring 5 . The channel body 811 is provided with a one-way valve 82 . The one-way valve 82 is opened towards the outside of the vacuum noise isolation chamber 8 (that is, only the gas in the vacuum noise isolation chamber can be discharged).

[0030] The air inlet 812 is an annular groove provided on the inner peripheral surface of the outer ring 2 and extending along the circumferential direction of the outer ring. The setting of the air inlet can improve the convenience when the channel body 811 and the air inlet 812 are d...

Embodiment 3

[0033] Embodiment three, see Figure 4 , a double-seal bearing, including an inner ring 1, an outer ring 2 sleeved on the inner ring, and a rolling element 3 located between the inner ring and the outer ring. The rolling elements 3 are rolling balls, needle rollers and rollers, etc., depending on the specific type of bearing.

[0034] The inner ring 1 is provided with an inner ring portion sealing ring 4 . The sealing ring 4 of the inner ring part is sealed and fixedly connected with the inner ring 1 by means of elastic clamping. The outer peripheral surface of the inner ring part sealing ring 4 is provided with an inner ring part sealing ring outer sealing lip 41 and an inner ring part sealing ring inner sealing lip 42 . The radially outer end of the outer sealing lip 41 of the sealing ring of the inner ring portion is inclined along the axially outward direction of the inner ring, that is, away from the rolling elements. The radially outer end of the inner sealing lip 42 ...

Abstract

The invention relates to a bearing. A double-sealing bearing comprises an inner ring, an outer ring sleeving the inner ring and a rolling member positioned between the inner ring and the outer ring, wherein the outer ring is in sealed fixed connection with an outer ring part sealing ring; the inner circumferential surface of the outer ring part sealing ring is in sealed butt joint with the inner ring; the inner ring is in sealed fixed connection with an inner ring part sealing ring; the outer circumferential surface of the inner ring part sealing ring is in sealed butt joint with the outer ring; the outer ring part sealing ring and the inner ring part sealing ring are positioned on the same side of the rolling member. By adopting the double-sealing bearing provided by the invention, the phenomenon of poor sealing does not occur often, and the sealing effect does not drop quickly in the case of abrasion of a movable sealing surface, thereby solving the problems of the existing bearing that the phenomenon of poor sealing occurs often and the sealing effect drops quickly in the case of abrasion of a movable sealing surface of the sealing ring.

Description

technical field [0001] The invention relates to a bearing, in particular to a double-sealed bearing. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads in the process of mechanical transmission, and are used to reduce the friction coefficient of mechanical loads in the transmission process of equipment. A bearing provided with a sealing ring is disclosed in a patent document whose Chinese patent number is 2009100504801, the authorized announcement date is July 4, 2012, and the title is "a full roller bearing". The basic structure of the bearing includes an inner ring, an outer ring fitted on the inner ring, and rolling elements between the inner ring and the outer ring as disclosed in this patent document. In order to prevent foreign matters from entering the rolling parts between the inner and outer rings and to prevent the lubricating oil in the bearing from overflowing, a sealing ring is provided between th...
