Abstract
The utility model relates to a closed deep groove ball bearing which comprises an outer ring, an inner ring, and a sealing ring arranged between the outer ring and the inner ring, wherein a sealing groove is formed in an inner wall of the outer ring; and the sealing ring is embedded into the sealing groove. The closed deep groove ball bearing is characterized in that an outer side wall of the sealing groove is in an arc shape bent to the outer side.According to the closed deep groove ball bearing, with the adoption of the technical scheme, the sealing ring can be located well to be prevented from falling, and further, the reliable sealability of the bearing is ensured.
Description
Technical field
The utility model relates to field of bearings, particularly a kind of enclosed deep groove ball bearing.
Background technique
Existing enclosed deep groove ball bearing, include outer ring, inner ring, be arranged on outer ring, ball between inner ring, seal ring, the inwall of described outer ring is provided with seal groove, described seal ring is embedded in described seal groove, the outer side wall of described seal groove is obliquely installed, but, the deep groove ball bearing of this structure, after embedding, seal ring easily produces distortion, seal groove outer side wall is little to the screens amount of seal ring, point of contact between seal ring and seal groove easily moves down, can not position seal ring well, be subject under impulsive load or air pressure inside effect, be easy to come off, or collapse lid, cause bearing seal, lubrication failure.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of enclosed deep groove ball bearing, and it is positioning seal ring well, prevents that it from coming off, and then ensure that bearing seal is reliable.
The technical solution of the utility model: a kind of enclosed deep groove ball bearing, include outer ring, inner ring, be arranged on outer ring, seal ring between inner ring, the inwall of described outer ring is provided with seal groove, described seal ring is embedded in described seal groove, it is characterized in that: the outer side wall of described seal groove is bending laterally circular-arc setting.
Adopt technique scheme, because the outer side wall of seal groove is laterally bending circular-arc, when seal ring snaps in like this, its with seal groove outer side wall between have enough buffering spaces, thereby can prevent seal ring embedding sealing groove time, generation is out of shape; Circular-arc outside wall energy prevents that the point of contact between seal ring and seal groove from moving down, thereby positioning seal ring well prevents that it from coming off, and then ensures that bearing seal is reliable.
Further setting of the present utility model: the outer ring inwall that is positioned at seal groove outside forms rib, the center of circle corresponding to outer side wall of described seal groove is positioned on the elongation line that rib extends to the inside, and corresponding radius and seal groove diapire to the distance between rib of outer side wall of described seal groove equates.
Adopt above-mentioned further setting, if the radius that seal groove outer side wall is corresponding is excessive or too small, all positioning seal rings well, seal ring outer side wall is little to the screens amount of seal ring, and the point of contact between seal ring and seal groove easily moves down, and, the center of circle, radius set-up mode that this seal groove outer side wall is corresponding, positioning seal ring well, and, convenient for the turning processing of seal groove outer side wall, diapire.
Further setting more of the present utility model: the madial wall of described seal groove is also circular-arc setting.
Adopt above-mentionedly further to arrange again, when seal ring snaps in like this, its with seal groove madial wall between also have enough buffering spaces, thereby can prevent from producing and being out of shape after seal ring embedding sealing groove, and then guarantee bearing seal is good.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is I part partial enlarged drawing in Fig. 1.
Embodiment
As shown in Figure 1, 2, a kind of enclosed deep groove ball bearing, include outer ring 1, inner ring 2, be arranged on outer ring 1, ball 3, seal ring 4 between inner ring 2, the inwall of described outer ring 1 is provided with seal groove 5, described seal ring 4 is embedded in described seal groove 5, the internal diameter that is positioned at outer ring 1 inwall in seal groove 5 outsides is greater than the internal diameter of outer ring 1 inwall that is positioned at seal groove 5 inner sides, can facilitate like this in seal ring 4 embedding sealing grooves 5, the outer side wall 51 of described seal groove 5 is bending laterally circular-arc setting.Because the outer side wall 51 of seal groove 5 is laterally bending circular-arc, when seal ring 4 snaps in like this, its with seal groove 5 outer side walls 51 between have enough buffering spaces, thereby can prevent seal ring 4 embedding sealing groove 5 time, generation is out of shape; Circular-arc outer side wall 51 can prevent that the point of contact between seal ring 4 and seal groove 5 from moving down, thereby positioning seal ring 4 well prevents that it from coming off, and then ensures that bearing seal is reliable.
In the utility model specific embodiment, outer ring 1 inwall that is positioned at seal groove 5 outsides forms rib 11, the outer side wall of described seal groove 5 is positioned on the elongation line that rib 11 extends to the inside 51 centers of circle of answering, and the radius of outer side wall 51 correspondences of described seal groove 5 and seal groove 5 diapires 53 to the distance between rib 11 equate.If the radius that seal groove 5 outer side walls are corresponding is excessive or too small, all positioning seal rings 4 well, seal ring 4 outer side walls are little to the screens amount of seal ring 4, point of contact between seal ring 4 and seal groove 5 easily moves down, and, the center of circle, radius set-up mode that this seal groove 5 outer side walls are corresponding, well positioning seal ring 4, and, convenient for the turning processing of seal groove 5 outer side walls 51, diapire 53.
In the utility model specific embodiment, the madial wall 52 of described seal groove 5 is also circular-arc setting.When seal ring 4 snaps in like this, between itself and seal groove 5 madial walls 52, also there are enough buffering spaces, thereby can prevent the rear generation distortion of seal ring 4 embedding sealing groove 5, and then ensure that bearing seal is good.
