Abstract
The utility model provides a bidirectional thrust self-aligning roller bearing, of which the bearing mounting space can be reduced and the replacement is convenient. The bidirectional thrust self-aligning roller bearing comprises a shaft washer, a seat ring, a roller, a retainer and retainer rings, wherein a double-column raceway ferrule is used as the shaft washer; a plurality of roller pockets are formed on the retainer; annular grooves are formed in the cylindrical surfaces on two sides of the shaft washer; the retainer rings are respectively arranged in the annular grooves and are used for fixing the retainer and the roller component; the roller is of a spherical surface; and the seat ring and the raceway surface of the shaft washer are of spherical surfaces. The bidirectional thrust self-aligning roller bearing can be directly mounted on the neck of the roller, so that the roller neck can be enlarged, and due to the design of the double-raceway shaft washer, the bearing mounting space is reduced, and a self-aligning function is kept; and therefore, the rigidity of the roller is greatly improved, the cost is reduced, and convenience is brought to installation and replacement.
Description
Technical field
The utility model relates to a kind of roller bearing, especially a kind of bidirectional propulsion selfaligning roller bearing.
Background technique
Existing steel rolling work roll working end block bearing is the unidirectional single-row self-aligning thrust roller bearings that adopt cover four-row tapered roller bearings and paired assembly to use generally more.Can bear bi-directional axial load like this, the aligning function in the time of realizing the work roll stress deformation again.But the aligning roller center of usefulness need to guarantee with spacer sleeve the transmission of power in pairs, has therefore just reduced the diameter of axle of work roll shaft, has also lengthened the length of work roll shaft simultaneously, makes axle become more elongated, easier generation distortion.
The model utility content
The utility model provides a kind of and has reduced the bearing installing space, changed easily bidirectional propulsion selfaligning roller bearing.
Realize the bidirectional propulsion selfaligning roller bearing of the utility model purpose, comprise blowout patche, seat ring, roller, retainer, back-up ring, described blowout patche is two raceway lassos, described retainer is provided with a plurality of roller pockets hole, cylndrical surface, described blowout patche both sides is provided with circular groove, respectively be provided with a back-up ring in the described circular groove, be used for fixed retainer and roller assembly; Described roller is sphere, and seat ring and blowout patche roller surface are sphere.
Cylndrical surface, described blowout patche both sides is positioned at described circular groove, respectively is provided with a back-up ring.
The beneficial effect of bidirectional propulsion selfaligning roller bearing of the present utility model is as follows:
Bidirectional propulsion selfaligning roller bearing of the present utility model can be directly installed on the roller neck, not only can strengthen roller neck, and the design of two raceway blowout patche has reduced the bearing installing space, the heart function of not lacking of proper care again; So just having improved significantly the rigidity of roll, reduced cost, also is that installation and replacing have brought convenience simultaneously.
Description of drawings
Fig. 1 is the structural representation of bidirectional propulsion selfaligning roller bearing of the present utility model.
Embodiment
As shown in Figure 1, bidirectional propulsion selfaligning roller bearing of the present utility model, comprise blowout patche 4, described blowout patche 4 is two raceway lassos, respectively is provided with a retainer 3 in the described raceway, and described retainer 3 is provided with a plurality of pockets hole, described pocket is provided with roller 2 in the hole, seat ring 1 is single raceway lasso, and described roller 2 is sphere, and seat ring 1 roller surface is sphere.Cylndrical surface, described blowout patche 4 both sides is provided with circular groove, is positioned at described circular groove, respectively is provided with a back-up ring 5.
The working principle of bidirectional propulsion selfaligning roller bearing of the present utility model is as follows:
Because seat ring 1 and blowout patche 4 roller surfaces are sphere, roller 2 is spherical, therefore has aligning function, and is insensitive to the amount of deflection of coaxality and axle.Blowout patche 4, roller 2, retainer 3 fixedly become unseparated integral body by two back-up rings, and two seat rings 1 are separable, are convenient to install.During work, seat ring 1 is not made radial support, only bears thrust load.When using bearing, after normally gland being compressed, with hold-down bolt slow astern set a distance, in order to avoid because of play too small, under the running temperature difference, cause stuck, if but the gap is bigger than normal, can form again separating between seat ring and bearing integral spare, when therefore using, need design spring eye at bearing support and cover plate end face, can guarantee like this tram of rolling element in raceway, reached again the purpose of pretension, and when being subject to axial float power, spring can play buffer function, minimizing prolongs bearing life to the damage of bearing.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in related domain make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
