Abstract
The utility model relates to an integrated inner ring of a double-row bearing, consisting of two single-track inner rings, which is characterized in that: the two single-track inner rings are formed by dividing an integrally formed double-track inner ring into halves along the radial direction and then connected into a whole by a seamless way through connecting rings. As the two inner rings are manufactured through an integral forming, the errors caused by separate manufacturing are reduced; therefore, the concentricity of the two tracks of the double-row bearing assembled by integrally formed outer rings is less than 0.005mm, thus ensuring the concentricity when the bearing is installed on the main frame, solving the problems of abrasion acceleration caused by the disalignment of the tracks and prolonging the service life of the bearing.
Description
Technical field
The present invention relates to a kind of double row bearing, particularly the inner ring of double row bearing.
Background technique
Double row bearing is because the columns increase, radial capacity increases, also can bear simultaneously bigger bi-directional axial load, therefore be applied to usually being mainly used in the footpath of bearing, the effect of axial connected load in the heavy machineries such as hub bearing, winch, hoist of heavy-duty gear transmission, heavy vehicle based on radial load.Double row bearing by one have the outer ring of two raceways, two single raceway inner rings, ball and retainers constitute.Because two inner rings are produced respectively, therefore can have certain difference each other, thereby cause two raceway decentraction of bearing, accelerate the wearing and tearing of ball to raceway in the using process, reduce the working life of bearing easily.
Summary of the invention
The utility model provides a kind of double row bearing inner ring of integrative-structure, and purpose is to solve the prior art problem, and the double row bearing inner ring that is structure as a whole that a kind of raceway is concentric, can increase the service life is provided.
The utility model technological scheme that adopts of dealing with problems is:
The double row bearing inner ring of integrative-structure is made of two single raceway inner rings, and described two single raceway inner rings are radially separately formed from middle position along it by integrated pair of raceway inner ring, and is one by connecting ring with both seamless links.
The beneficial effects of the utility model: two inner rings are one-body molded produced, reduced and made the error that produces respectively, therefore the double row bearing that is assembled into one-body molded outer ring, the concentricity of two raceway is below 0.005mm, guaranteed the concentricity of Bearing Installation on main frame, solved problem, prolonged the working life of bearing because of raceway decentraction enhance faster wear.
Description of drawings
Fig. 1 is equipped with double row bearing sectional view of the present utility model
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the double row bearing inner ring 100 of integrative-structure, constitute by two single raceway inner rings 1,2, described two single raceway inner rings 1,2 are radially separately formed from middle position along it by integrated pair of raceway inner ring, and are one by connecting ring 3 with two single raceway inner ring 1,2 seamless links.
Two inner rings the 1, the 2nd, one-body molded produced, reduced and made the error that produces respectively, therefore the double row bearing that is assembled into one-body molded outer ring, the concentricity of two raceway is below 0.005mm, guaranteed the concentricity of Bearing Installation on main frame, solved problem, prolonged the working life of bearing because of raceway decentraction enhance faster wear.
