Abstract

The utility model relates to a sealing assembly structure, which is used for sealing and protecting a bearing. The utility model is combined of reinforced seals, labyrinth seals, and O-shaped sealing rings, wherein, the reinforced seals are positioned at the side part of the bottom of a sealed bearing, and are impacted by the labyrinth seals which are positioned at the side part of the bearing; a support bearing seat matches with the labyrinth seals, and the O-shaped sealing rings are arranged at the contact gaps between the support bearing seat and the labyrinth seals. Because of adopting an assembly structure, the utility model has the advantages that the sealing performance is enhanced; the utility model is suitable for high-pressure occasions.

Description

The seal combination structure

The utility model relates to a kind of seal combination structure of bearing being carried out seal protection.

Seal protection to bearing etc. in the common mechanical often adopts oil sealing, O RunddichtringO, often uses separately.But, adopt a kind of sealing configuration often can not meet the demands separately at some special occasions.Vacuum brick and tile extruding machine (number of patent application 00226865.5) as the applicant's patent applied for; because bearing is positioned at vacuum chamber one end; during work pug around the bearing support by and bearing coated fully; therefore very high to the seal protection requirement of bearing, if seal failure will make complete machine work.

The utility model purpose is to design a kind of more following bearing seal composite structure of using of stringent condition that satisfies.

The utility model project organization: a kind of seal combination structure that is used for bearing is carried out seal protection; it is characterized in that: combine by outside framework oil seal (2,12), labyrinth seal (3,5,7,10) and O RunddichtringO (4,8); the labyrinth seal (3,5,7,10) that outside framework oil seal (2,12) is positioned at the bottom side of sealed bearing and is positioned at the bearing sidepiece compresses; supporting shaft holder (9) and labyrinth seal (3,5,7,10) are combined together, and in its contact gap the O RunddichtringO are arranged (4,8).

Described labyrinth seal is made up of with its concavo-convex labyrinth lid (3,10) that cooperates respectively the labyrinth disc that is positioned at the bearing both sides (5,7).

The utility model advantage is that the composite structure sealing is reliable, simple in structure, easy to maintenance, can guarantee that bearing working is reliable, reduces maintenance expenses greatly.

Description of drawings:

Fig. 1 is installed in schematic representation on the vacuum brick and tile extruding machine for the utility model.

Fig. 2 is the utility model structural representation (A portion amplifies among Fig. 1).

The figure number explanation:

1-main shaft 2-outside framework oil seal I 3-labyrinth lid I 4-O RunddichtringO I

5-labyrinth disc I 6-bearing 7-labyrinth disc II 8-O RunddichtringO II

9-supporting shaft holder 10-labyrinth lid II 11-tapered sleeve 12-outside framework oil seal II

Embodiment: a kind of seal combination structure that is used for bearing is carried out seal protection; combine by outside framework oil seal I 2 and outside framework oil seal II 12, labyrinth seal (3,5,7,10), O RunddichtringO I 4 and O RunddichtringO II 8; outside framework oil seal I, II are positioned at the bottom side of sealed bearing and are positioned at the labyrinth seal of bearing sidepiece (3,5,7,10) and compress; supporting shaft holder 9 and labyrinth seal (3,5,7,10) are combined together, and O RunddichtringO I, II are arranged in its contact gap.

Labyrinth seal is made up of with its concavo-convex labyrinth lid I 3 that cooperates, labyrinth lid II 10 respectively the labyrinth disc I 5 that is positioned at the bearing both sides, labyrinth disc II 7.

Claims

1, a kind of seal combination structure that is used for bearing is carried out seal protection; it is characterized in that: combine by outside framework oil seal (2,12), labyrinth seal (3,5,7,10) and O RunddichtringO (4,8); the labyrinth seal (3,5,7,10) that outside framework oil seal (2,12) is positioned at the bottom side of sealed bearing and is positioned at the bearing sidepiece compresses; supporting shaft holder (9) and labyrinth seal (3,5,7,10) are combined together, and in its contact gap the O RunddichtringO are arranged (4,8).

2, seal combination structure according to claim 1 is characterized in that: labyrinth seal is made up of with its concavo-convex labyrinth lid (3,10) that cooperates respectively the labyrinth disc that is positioned at the bearing both sides (5,7).
