Abstract

The utility model discloses a single-row spherical surface roller bearing, specifically, which is a single-row spherical surface roller bearing that has aligning function and relatively axial displacement function between inner and outer rings. The bearing comprises an inner ring and an outer ring, and is characterized in that a row of rollers are uniformly distributed between the inner ring and the outer ring in the circumferential direction. The rollers are symmetrical spherical rollers. Raceways on the inner ring and the outer ring are concave, and gaps are left between the roller and the raceways of the inner ring and the outer ring. The single-row spherical surface roller bearing has multiple functions and long service life.

Description

Single-row spherical-roller bearing
Technical field
The utility model relates to a kind of bearing.Specifically, be not only to have had the aligning function, but also have the single-row spherical-roller bearing that can carry out displacement function to axial between Internal and external cycle.
Background technique
All know at machine industry, traditional bearing or have only for example selfaligning roller bearing of aligning function, or have only for example roller bearing of Internal and external cycle displacement function to axial.When the former is used on the main frame major axis of aligning requirement, after major axis one end is fixed,, can produce axial displacement between the bearing enclose of the main shaft the other end owing to expand with heat and contract with cold, make this bearing have only a row roller stressed, to damage easily, working life is shorter.Though the latter has Internal and external cycle displacement function to axial, can not aligning, and the aligning of main shaft when operation also can make the roller unbalance stress, like this, also can shorten the working life of bearing.In a word, above-mentioned two kinds of bearing function singlenesses, working life is short.
The model utility content
Problem to be solved in the utility model is the defective that overcomes background technique, a kind of single-row spherical-roller bearing is provided.This single-row spherical-roller bearing, function is many, long service life.
For addressing the above problem, take following technological scheme:
Single-row spherical-roller bearing of the present utility model contains inner ring and outer ring, is characterized in that the circumferencial direction between inner ring and the outer ring is evenly equipped with a row roller.Described roller is the symmetry properties spherical roller, and the raceway on inner ring and the outer ring is a spill, and leaves the gap between the raceway on roller and inner ring and the outer ring.
Wherein, can be provided with retainer between inner ring and outer ring, described roller is installed on the retainer.
Also can at roller one end stop ring be set without retainer.With the corresponding outer ring of this stop ring inner side surface circumferential recess is arranged, the outside of stop ring embeds in the circumferential recess, and leaves spacing between stop ring inside edge and inner ring.
Take such scheme, have the following advantages:
Because the circumferencial direction between inner ring and the outer ring is evenly equipped with a row roller, described roller is the symmetry properties spherical roller, and the raceway on inner ring and the outer ring is a spill, and leaves the gap between the raceway on roller and inner ring and the outer ring.Both had the aligning function, had the relative displacement function between Internal and external cycle again.Not only function is many, and long service life.

Fig. 2 is an another kind of single-row spherical-roller bearing structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of single-row spherical-roller bearing of the present utility model contains inner ring 3 and outer ring 1, is provided with retainer 4 between inner ring 3 and the outer ring 1, along a row roller 2 is installed on the circumferencial direction of retainer 4.Described roller 2 is the symmetry properties spherical roller, and the raceway on inner ring 3 and the outer ring 1 is the spill circular arc, and leaves the gap between the raceway on roller 2 and inner ring 3 and the outer ring 1.
As shown in Figure 2, another kind of single-row spherical-roller bearing of the present utility model contains inner ring 3 and outer ring 1, and the circumferencial direction between inner ring 3 and the outer ring 1 is evenly equipped with a row roller 2.Described roller 2 is the symmetry properties spherical roller, and the raceway on inner ring 3 and the outer ring 1 is the spill circular arc, and leaves the gap between the raceway on roller 2 and inner ring 3 and the outer ring 1.End at roller 2 is provided with stop ring 5, and is processed with circumferential recess on this stop ring 2 corresponding outer rings 1 inner side surface, and the outer edge of stop ring 5 embeds in the circumferential recess, and stop ring 5 inside edges and 3 of inner rings leave spacing.
Above-mentioned two kinds of roller bearings not only all have the aligning function, and inner ring 3 and 1 of outer ring also have the relative displacement function.Therefore, function is many, long service life.
