Abstract
The utility model relates to a novel second radial thrust ball bearing mainly composed of an outer ring 1, a center ring 3, am inner ring 6 and three roller balls assemblies 2, 4, 5, wherein, the roller balls assemblies 2, 5 are arranged on the same circumference between the outer ring 1 with concave holes and the center ring 3 with concave holes; the roller balls assembly 4 is arranged in a concave hole between the center ring 3 with concave holes and the inner ring 6; the connecting lines of the centre of the spheres of the roller balls assembly 4 and the roller balls assemblies 2, 5 are arranged in a isosceles triangle shape. The utility model has the advantages of compact structure, low friction factor, high speed and long service life, and the utility model can bear axial force and simultaneously bear radial force.
Description
The utility model belongs to the general novel secondary angular contact ball bearing in the mechanical engineering field.
The utility model is to have increased several centre circles and some groups of transmission balls in the former patent " Multistage bearing " of inventing on the basis of original utility model patent " Multistage bearing " (patent No. 90208408.9) on traditional single-stage bearing that is formed by outer ring, inner ring, bracket supports " Multistage bearing " between ball is enclosed by each is though friction factor is low, rotating speed is high, long service life, but its use will be subjected to the circumferential size of bearing, i.e. the restriction of radial dimension.
The purpose of this utility model is to design a kind ofly can increase bearing progression, keep that former " Multistage bearing " friction factor is low, rotating speed is high, long service life, energy-conservation taping the latent power and plurality of advantages such as efficient, again can be by ingenious, the rational deployment of three groups of balls, its radial dimension is dwindled greatly, and can be when bearing axial force bearing radial force.
The utility model is achieved in that novel secondary angular contact ball bearing comprises inside and outside circle, centre circle and three groups of balls 2,4,5.Two groups of balls 2,5 are installed between the outer ring 1 and centre circle 3 of band shrinkage pool, and ball set 4 is installed between the centre circle 3 and inner ring 6 of band shrinkage pool.
Be described as follows with reference to the accompanying drawings below:
Fig. 1 structural representation of the present utility model
Fig. 2 cross-sectional view of the present utility model
Ball set 2,5 is arranged on the same circumference between outer ring 1 and the centre circle 3.The circumference centre of sphere link position that is arranged in the ball set 4 between centre circle 3 and the inner ring 6 on the symmetrical position of the circumference centre of sphere line of ball set 2,5, promptly ball 4, with the centre of sphere line of ball 2,5 be isosceles triangle.
The utility model compact structure, friction factor is low, rotating speed is high, long service life, can bearing radial force when bearing axial force.
