Description
Technical field
The utility model belongs to the rolling bearing class, particularly is applicable to a kind of composite rolling bearing that the screw conveyor in the shield excavation machine is used in the large-scale mine enterprise.
Background technique
As everyone knows, the bearing in the screw conveyor adopts tapered roller bearing or other conventional bearing mostly, and its structure is made up of outer ring, inner ring and rolling element; Because this bearing need bear bigger axial force, inner ring needs certain pivot angle again, so the working life of these bearings is all shorter; Especially the rolling bearing that the screw conveyor in the shield excavation machine is used in large-scale mine enterprise, because screw rod is long and free arm, the swing that can not stop during work; Working strength is big simultaneously, and environment is very abominable, and the life-span of therefore causing bearing is short, and Ji increases maintenance expenses influences manufacturing efficiency again.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, compact structure, can bear bigger axial force and radial force, satisfy bigger pivot angle again, and has good airproof performance, long service life, the low and a kind of very easily composite rolling bearing of use of maintenance expenses.
The purpose of this utility model is to adopt following technological scheme to realize: described composite rolling bearing, comprise outer ring, inner ring and rolling element, it is characterized in that: described outer ring is made up of crowned teeth outer ring and branch outer ring, on the sphere shape outer side surface of crowned teeth outer ring, be provided with crowned teeth, on minute outer ring end face by bolt and crowned teeth outer ring circle body that link into an integrated entity, that have sphere shape outer side surface; Outer side surface in the crowned teeth outer ring is provided with the crowned teeth shell that is meshed with crowned teeth, connects in the outside of minute outer ring and divide shell, the shell that links into an integrated entity by bolt and crowned teeth shell on the end face of minute shell; Symmetry installing axial antifriction bearing is installed annular bearing with rolling contact in the rolling groove between outer ring and inner ring between two row axial antifriction bearings; The sealing support ring is housed in the axis hole in the crowned teeth outer ring, the installing sealing layer distributes between crowned teeth outer ring and sealing support ring, on the crowned teeth cycle surface of sealing layer, connect sealing gland by screw, on crowned teeth outer ring and the contacted crowned teeth of crowned teeth shell outer ring face, distribute and install seal ring, near the seal ring installing sealing platen of crowned teeth shell end face.
Arranged distribution is equipped with several axial cylindrical rolling elements in the retainer of described every row axial antifriction bearing; Arranged distribution is equipped with the several cylinders rolling element in the retainer of described every row annular bearing with rolling contact.Principle of the present utility model and operation are described below:
Can bear bigger axial force and radial force owing in the utility model, adopted the three row cylinder axis of rolling just can hold; Its outer ring is to form the circle body with sphere shape outer side surface by crowned teeth outer ring and branch outer ring, on the sphere shape outer side surface of crowned teeth outer ring, be provided with the crowned teeth shell of crowned teeth, on minute outer ring end face cloth with bolt and crowned teeth outer ring incorporated outer ring; Satisfy bigger pivot angle and can prevent the relative movement that Internal and external cycle is circumferential by crowned teeth and sphere, thereby protected the cylinder rolling element in axial antifriction bearing and the annular bearing with rolling contact, and in the utility model, be distributed with the sealing of sealing layer and seal ring and in sphere and crowned teeth grease lubrication, the ball thin oil lubricant, protected the lubricated of bearing inside, and the intrusion of foreign object; Just having improved sealing and working life widely extends greatly.
Combine the above technological scheme of being taked, realize the purpose of this utility model.
Compared with prior art, the utlity model has following characteristics:
1, adopts the three row cylinder axis of rolling just can hold and to have born bigger axial force and radial force.
2, the spherical structure of band crowned teeth can satisfy bigger pivot angle.
3, be provided with the multiple-sealed of sealing layer and seal ring and just can have well protected the lubricated of bearing inside, and the intrusion of foreign object.
Therefore the utility model is not only reasonable in design, and compact structure can bear bigger axial force and radial force, and satisfy bigger pivot angle again, and have good airproof performance, long service life, maintenance expenses is low and use advantages such as very convenient.
