Description

Technical Field

[0001] The utility model relates to the technical field of rolling bearings, in particular to a single-row angular contact self-aligning roller bearing. Background Art

[0002] For the support ends of some transmission shaft systems with narrow space, high rotational speed, large ratio of axial force to radial force, insufficient rigidity and large shaft system deflection, if tapered roller bearings or cylindrical roller bearings are selected, they cannot adapt to the working conditions with large shaft system deflection. If ball bearings are selected, they cannot adapt to the working conditions with large axial force. Content of the Utility Model

[0003] The utility model aims to overcome the above technical defects and provides a single-row angular contact self-aligning roller bearing, which can bear radial and combined loads of bearings.

[0004] To achieve the above object, the technical solution adopted by the utility model is: a single-row angular contact self-aligning roller bearing, including an outer ring, an inner ring, a plurality of rollers and a cage. An outer raceway for rolling contact with the rollers is provided on the outer ring, and an inner raceway for rolling contact with the rollers is provided on the inner ring; the cage is located between the outer ring and the inner ring, and a plurality of pocket holes are provided on the cage, and the plurality of rollers are installed in the pocket holes of the cage. The included angle between the bearing pressure action line and the plane perpendicular to the axis is 10° - 45°. The inner ring, outer ring and roller assembly are separable, which is convenient for installation and has good use effect.

[0005] Further, the axial width of the cage is greater than the axial width of the outer ring, and both ends of the cage expose outside the outer ring.

[0006] Further, the axial width of the cage is greater than the axial width of the inner ring. The thickness of one end of the inner ring is less than that of the other end, and one end of the cage exposes the end with a smaller thickness of the inner ring. Since the bearing size is small, increasing the width of the cage can improve the strength of the bearing.

[0007] Further, the axial width of the inner ring is greater than the axial width of the outer ring.

[0008] Further, the outer raceway is a spherical arc surface, and the center of the spherical arc surface coincides with the center of the bearing. This design enables the roller cage assembly to operate at a certain deflection angle.

[0009] Further, the included angle between the bearing pressure action line and the plane perpendicular to the axis is 45°. This design enables the bearing to bear radial and axial combined loads. The larger the angle, the higher the axial load bearing capacity.

[0010] Further, the plurality of rollers are evenly distributed in the circumferential direction of the bearing ring to form a single-row form.

[0011] Further, the material of the cage is nylon.

[0012] Further, the outer ring, inner ring and rollers are separable structures. The separability of the outer ring, inner ring and rollers facilitates installation and ensures good performance.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] When in use, the single-row angular contact self-aligning roller bearing of the present utility model can withstand combined radial and axial loads. The larger the angle, the higher the axial load-carrying capacity. The inner ring, outer ring and roller assembly are separable, which facilitates installation and ensures good performance.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some, rather than all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present application belong to the scope of protection of the present application.

[0020] As Figure 1 shown, a single-row angular contact self-aligning roller bearing includes an outer ring 1, an inner ring 2, a plurality of rollers 3 and a cage 4. An outer raceway for rolling contact with the rollers 3 is provided on the outer ring 1, and an inner raceway for rolling contact with the rollers 3 is provided on the inner ring 2; the cage 4 is located between the outer ring 1 and the inner ring 2. A plurality of pocket holes are provided on the cage 4, and the plurality of rollers 3 are installed in the pocket holes of the cage. The included angle between the bearing pressure action line and the plane perpendicular to the axis is 10° - 45°. The inner ring, outer ring and roller assembly are separable, which facilitates installation and ensures good performance.

[0021] Further, the axial width of the cage 4 is greater than the axial width of the outer ring 1, and both ends of the cage 4 protrude from the outer ring 1.

[0022] Further, the axial width of the cage 4 is greater than the axial width of the inner ring 2. One end of the inner ring 1 has a smaller thickness than the other end, and one end of the cage 4 protrudes from the end of the inner ring 1 with a smaller thickness. Since the bearing has a small size, increasing the width of the cage can improve the strength of the bearing.

[0023] Further, the axial width of the inner ring 2 is greater than the axial width of the outer ring 1.

[0024] Further, the outer raceway is a spherical arc surface, and the center of the spherical arc surface coincides with the center of the bearing. This design enables the roller cage assembly to operate at a certain deflection angle.

[0025] Further, the angle between the bearing pressure action line and the plane perpendicular to the axis is 45°. This design enables the bearing to withstand combined radial and axial loads. The greater the angle, the higher the axial load-carrying capacity.

[0026] Further, a number of the rollers 3 are evenly distributed in the circumferential direction of the bearing ring to form a single-row form.

[0027] Further, the material of the cage 4 is nylon.

[0028] Further, the outer ring 1, the inner ring 2, and the rollers 3 are separable structures. The outer ring 1, the inner ring 2, and the rollers 3 are separable, which is convenient for installation and has good usability.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings).
