Abstract
The invention relates to a novel railway hub bearing labyrinth oil seal, which consists of a metal outer skeleton, a metal inner sleeve and a rubber double lip. The metal inner sleeve is positioned in the metal outer skeleton, and the rubber double lip is located between the metal outer skeleton and the metal inner sleeve. The metal outer skeleton tightly bonds with the rubber double lip through vulcanization. The rubber double lip and the metal inner sleeve adopt a surface non-contact design, and the space between them is filled with lubricating grease. With the advantages of simple structure and low cost, etc., the novel railway hub bearing labyrinth oil seal provided by the invention can realize the functions of high foreign matter protection capability, low bearing working temperature and energy consumption, and small friction torque of seal lip.
Description
Technical field
The invention belongs to railway wheel hub bearing enclosure technical field, be specifically related to a kind of novel railway hub bearing labyrinth oil seal.
Background technique
At present, in the application of traditional railway bearing enclosure, employing be general lock ring spring structure, main lip and hub spindle Interference contact, work friction torque is larger, becomes the principal element of " hot box ".In structural design, due to the complexity of railway wheel hub bearing working, easily cause oil sealing effect can not reach standard design value.Therefore, existing railway bearing oil seal structure can not meet actual need of production,, the operating temperature of bearing high in the urgent need to a kind of foreign matter protective ability and the bearing enclosure structure that energy consumption is low and sealing lip friction torque is little.
Summary of the invention
The problem existing in order to solve above-mentioned prior art, the invention provides a kind of novel railway hub bearing labyrinth oil seal, can realize that foreign matter protective ability is high, the operating temperature of bearing and energy consumption is low and sealing lip friction torque is little function.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of novel railway hub bearing labyrinth oil seal, is made up of the outer skeleton of metal, inner metal sleeve and rubber dicheilia, and described inner metal sleeve is positioned at the outer skeleton of metal inside, and rubber dicheilia is outside metal between skeleton and inner metal sleeve.The outer skeleton of described metal is by sulfuration and rubber dicheilia tight bond.Described rubber dicheilia and inner metal sleeve adopt surperficial non-contact design, repack with grease between the two.
The invention has the beneficial effects as follows: a kind of novel railway hub bearing labyrinth oil seal, there is the advantages such as simple in structure and cheap, can realize that foreign matter protective ability is high, the operating temperature of bearing and energy consumption is low and sealing lip friction torque is little function.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure 1, inner metal sleeve, 2, rubber dicheilia, 3, the outer skeleton of metal.
Embodiment
As shown in Figure 1, a kind of novel railway hub bearing labyrinth oil seal of the present invention, be made up of the outer skeleton 3 of metal, inner metal sleeve 1 and rubber dicheilia 2, described inner metal sleeve 1 is positioned at the outer skeleton of metal 3 inside, and rubber dicheilia 2 is outside metal between skeleton 3 and inner metal sleeve 1.The outer skeleton 3 of described metal is by sulfuration and rubber dicheilia 2 tight bond.Described rubber dicheilia 2 adopts surperficial non-contact design, repack with grease between the two with inner metal sleeve 1.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
