Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
Referring to the attached drawings 1-2, the double-face sealed self-aligning roller bearing comprises an outer ring 1, an inner ring 2, rollers 3, a retainer 4 and a sealing ring 5, wherein the rollers 3 are kept between the outer ring 1 and the inner ring 2 through the retainer 4; the raceway both sides of inner circle 2 be provided with the flange respectively, the outer face of cylinder of flange is provided with the seal groove, sealing washer 5 install in the seal groove, the outer face of cylinder of sealing washer 5 is provided with single seal lip 5.1, single seal lip 5.1 and outer lane raceway interference contact, sealing washer 5 supports through annular frame 5.2.
Based on the technical scheme, the sealing groove is designed on the inner ring flange, the sealing ring is fixed on the inner ring, the length of the outer ring raceway is not reduced, the length of the roller is increased, the bearing capacity of the bearing is improved as much as possible in a limited space, and the purpose of light weight is achieved. The single-lip sealing structure is adopted, and compared with a double-lip sealing structure, the bearing has small friction force and high rotating speed; compared with a double-lip sealing structure, the single-lip sealing structure needs to wrap the sealing glue outside the steel framework, so that the sealing structure has long service life and good dimensional stability, and is not easy to deform in an environment with temperature difference change; and the single-lip sealing structure is simple and easy to install, and saves cost. Because the outer ring raceway is a spherical surface, the interference magnitude of the single lip of the sealing structure and the outer ring raceway is unchanged within the range of the aligning angle of the bearing. Compared with a double-lip sealing structure. Because of the width of the double lips, one lip leaves the outer ring unless the double lips are on the outer ring raceway when the bearing is aligned at a large aligning angle. In addition, because the double lips are designed to be wide, the length of the bearing roller is short and the load is small in order to ensure the aligning angle.
Further, the seal ring 5 is axially assembled in the seal groove in an interference fit mode. The sealing ring 5 is ensured not to fall off, and the mounting stability is ensured.
Further, annular skeleton 5.2 sets up inside the sealing washer, and the outer parcel rubber of annular skeleton forms the sealing washer structure. The structural strength of the sealing ring can be ensured by the annular framework, and the rubber layer wrapped outside can provide better elastic deformation characteristics.
Preferably, the annular skeleton 5.2 is a steel skeleton.
Furthermore, the outer ring raceway is a spherical raceway, and the interference between a single seal lip 5.1 of the seal ring and the outer ring raceway is ensured to be unchanged during bearing aligning.
Furthermore, the single sealing lip 5.1 is of an angular structure, and the angular end face of the single sealing lip 5.1 is in interference contact with the outer ring raceway.
Based on above-mentioned technical scheme, the angular structure reduces the area of contact of sealing washer and bearing inner race raceway, avoids producing the high friction torque of imaginary to eliminate because of the rotatory sealing washer that causes of sealing washer is dragged or is piled up.
Further, the seal groove is arranged in the middle of the outer cylindrical surface of the flange. The sealing ring can effectively prevent external impurities from entering the bearing, and can avoid the interference of the sealing ring with the end face of the roller when the sealing ring is subjected to axial force.
The utility model discloses a sealing washer is steel skeleton rubber coating structure, and inner circle flange design seal groove, sealing washer pass through axial interference to be fixed in the seal groove, rotate together with the inner circle, and the sealing washer be single lip and with outer lane raceway interference contact, because the outer lane is the sphere, guarantee during the bearing aligning that the single lip and the outer lane raceway interference magnitude of sealing washer are unchangeable.
