[0022] Specific implementation mode two: combination figure 1 with figure 2 To describe this embodiment, the single-side maximum self-aligning angle A of the bearing is 19°. With this design, the maximum self-aligning angle A of the bearing is related to the diameter and axial width of the outer diameter surface of the inner ring 2 of the bearing, and the diameter and axial width of the inner diameter surface of the outer ring 1. The inner diameter of the outer ring is 22mm, and the outer diameter of the inner ring is 18.24mm, the axial width of the inner diameter surface of the outer ring is 10.9-11.1mm, and the axial width of the middle part of the outer diameter surface of the inner ring is 15.84-15.86mm. Other compositions and connections are the same as those in the first embodiment.

[0023] Specific implementation mode three: combination figure 1 with figure 2 To illustrate this embodiment, the two ends of the outer ring 1 are symmetrically provided with a groove 1-1 with a cross section of "7" shape, and the side wall of the groove 1-1 is arranged perpendicular to the central axis of the bearing, and, The other side wall of the groove 1-1 is arc-shaped, and the dust cover 3 is clamped in the groove 1-1. With this design, the dust cover 3 is fixedly connected with the grooves 1-1 at both ends of the outer ring 1, and adopts a non-contact seal with a dust-proof function, which can prevent impurities from entering the bearing and causing damage to the bearing when the bearing is running under special working conditions. When the bearing does not run normally, it will break down. The structure is simple, the installation is firmer, and the sealing effect is better; . Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2....

Abstract

The invention discloses a double-row full-ball self-aligning ball bearing with a large self-aligning angle, and belongs to the technical field of bearings. The double-row full-ball self-aligning ball bearing with the large self-aligning angle solves the problems that an existing self-aligning ball bearing is small in self-aligning angle range, and cannot meet special working condition needs of low starting torque and a large operating angle. The double-row full-ball self-aligning ball bearing comprises an outer ring, an inner ring, two dustproof covers and a plurality of rolling bodies, wherein the middle cross section of the outer radial surface of the inner ring and the cross section of the inner radial surface of the outer ring are in the shape of circular arc; a curvature center of the inner radial surface of the outer ring is consistent with that of the middle of the outer radial surface of the inner ring; two ring-shaped roller paths which are arranged side by side are arranged in the circumferential direction on the outer radial surface of the inner ring; the two ring-shaped roller paths are symmetrically arranged with respect to the radial central line of the inner ring; the plurality of rolling bodies are tightly arranged in the two ring-shaped roller paths separately; the dustproof cover is a ring-shaped plate; and the two dustproof covers are fixedly arranged at the two ends of the outer ring symmetrically, and are positioned between the outer ring and the inner ring. According to the double-row full-ball self-aligning ball bearing disclosed by the invention, the self-aligning angle of the bearing is effectively increased.

Description

technical field [0001] The invention relates to a double-row full-spherical self-aligning ball bearing with a large self-aligning angle, which belongs to the technical field of bearings. Background technique [0002] The self-aligning ball bearing is a bearing whose outer ring raceway is a spherical surface, and the curvature center of the outer ring raceway surface is consistent with the center of the bearing, and has self-alignment. It mainly bears radial load, and can bear small axial load at the same time, allowing the inner and outer rings to work normally under the condition of small relative inclination. It is suitable for components whose bearing seat holes cannot strictly guarantee the coaxiality, including precision instruments , Low-noise motors, automobiles, motorcycles, aircraft and other industries. At present, the self-aligning angle range of domestic self-aligning ball bearings is generally 0-3°; in foreign countries, it is generally 0-4°, and the maximum se...
