Problems solved by technology

The internal size of this type of bearing has become a standard design in China. Due to structural design reasons, the spherical roller bearing of this design has disadvantages such as small load capacity, low impact resistance, and large temperature rise during operation.
Sealed design bearings are less produced in China, and the grease is easy to leak when the bearings are running, and most of the sealing materials are made of fluororubber, which will produce harmful gases at higher temperatures, and will still be harmful to operators after the temperature drops. Harmful to the body

Embodiment 1

[0025] Embodiment one, as attached Figure 5 Shown: its parts of the bearing of the present invention comprise outer ring 1, inner ring 2, roller 3, cage 4, middle retaining ring 5.

[0026] as attached Figures 5 to 7 As shown: the axial section of the cage 4 is a "C"-shaped profile, which is formed by one-piece stamping, and is functionally divided into a roller mounting part 41 and a process chamfer 43 . Among them, the angle a between the widest part of the roller mounting part 41 and the center of the bearing and the radial section of the bearing is equal to the nominal contact angle (nominal contact angle: the nominal contact angle α is the contact point between the rolling body and the ring raceway The angle between the normal n of the bearing and the radial plane of the bearing. The larger the α, the greater the ability of the bearing to withstand axial load), the shape of the roller mounting part of the cage is a spherical R profile 42, which is consistent with the c...

Embodiment 2

[0030] like Figures 10 to 12 As shown, on the basis of Embodiment 1, two pieces of nitrile rubber or hydrogenated nitrile rubber contact seal ring 6 with steel skeleton and three set screws 7 arranged in the three oil holes of the outer ring and the outer ring are formed. First of all, the sealing groove 11 for installing the sealing ring is machined at both ends of the outer ring, and the beveled edge 21 is ground at the outer openings on both sides of the inner ring. When assembling, the inner ring 2, outer ring 1, roller 3, Cage 4 and sealing ring 5 are installed, inject lubricating grease, and finally assemble sealing rings 6 and set screws 7 on both sides. When assembling, place sealing ring 6 flat in the sealing groove 11 of the outer ring. The hypotenuse 21 applies a pre-tightening force to the sealing lip 61 of the sealing ring. Its function is to ensure that the good sealing performance can still be maintained when the bearing is running. Press the auricle 62 of the...

Abstract

The invention discloses a full complement self-aligning roller bearing, comprising an inner ring, an outer ring, rollers, a retainer and a middle check ring, wherein the retainer is formed by stamping a high-quality cold-roll steel sheet, the axial section of the stamping retainer is in a C-shaped outline, roll installing parts are distributed in a dual-row crossed mode, so that the rollers inside are designed to be in a full complement state; the middle check ring is in a tri-sectional design and is guided by an outer ring raceway. The bearing adopts an open-type design and a sealing-type design. The bearing with the opening-type design has the advantages of extremely high carrying capacity, long service life, high impact resistance, simple manufacturing process, material reduction and small temperature rise in operation. Besides all the advantages of the open-type design, the bearing with the sealing design also has the unique advantages of harmlessness at a high working temperature, good sealing property, water, moisture and pollution resistance, and maintenance-free property in lifetime.

Description

technical field [0001] The invention relates to the technical field of bearings, mainly relates to a structural type of a full complement spherical roller bearing, and also relates to a sealed full complement spherical roller bearing designed with the internal structure, which is especially suitable for harsh operating environments. Background technique [0002] At present, spherical roller bearings with stamped cages, such as figure 1 Shown: It is composed of outer ring 1, inner ring 2, roller 3, stamping cage 4, and intermediate retaining ring 5. The internal dimensions of this type of bearing have become a standard design in China. Due to structural design reasons, the spherical roller bearing of this design has disadvantages such as small load capacity, low impact resistance, and large temperature rise during operation. Sealed design bearings are less produced in China, and the grease is easy to leak when the bearings are running, and most of the sealing materials are m...
