Description
Technical field
The utility model relates to extra large size bearing technical field, is specifically related to a kind of roller turntable bearing with dust-proof cover.
Background technique
At present, in heavy-duty machinery technical field, bearing is the core of this equipment, because it is except having supporting pole heavy load revolute function, also to bear great tilting moment, to adapt to the transhipment of remote heavily loaded goods, turntable bearing is because of its stronger bearing capacity in extensive use and large lifting equipment, because the working environment of large lifting equipment is usually comparatively severe, existing bearing only has single sealing configuration (as shown in Figure 1), cannot effectively in the face of large particle dust, the outside foreign material invasion such as iron scale is collected near sealing configuration, thus reduce the working life of bearing, improve the user cost of user, reduce oiling agent consumption.
Model utility content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and provides a kind of roller turntable bearing with dust-proof cover, effectively can prevent large particle dust and other impurities from destroying the sealing mechanism of bearing, thus improve the working life of bearing.
The utility model is the deficiency solved the problems of the technologies described above, the technological scheme adopted is: a kind of roller turntable bearing with dust-proof cover, comprise inner ring, outer ring, roller and retainer, roller is arranged between outer ring and inner ring by retainer, and the two ends of inner ring and outer ring are respectively equipped with the seal ring can closing bearing cavity, the seal ring place, two ends of described roller turntable bearing is provided with dust-proof cover, dust-proof cover is made up of the outer outlet body be fixed on outer ring and the dust retaining ring be fixed on inner ring, described outer outlet body is located at the outside of seal ring, one end of outer outlet body is fixed on outer ring, another dust-break end of outer outlet body and inner ring outer surface have gap, described dust retaining ring is arranged in outer outlet body, dust retaining ring to be fixed on inner ring and to have gap between the exterior edge face of dust retaining ring and outer outlet body.
In order to the convenience of installing, described dust retaining ring is connected with the installing ring for being fixed on inner ring, one end of installing ring is located on inner ring by clamping bolt fixed cover, and the other end of installing ring stretches into from the gap between outer outlet body with inner ring and is fixedly connected with dust retaining ring.
The shape of dust retaining ring can be a variety of, and as wherein a kind of, the ring body of described dust retaining ring is arranged perpendicular to the axis of outer ring, and the dust-break end of outer outlet body and the ring body of dust retaining ring are parallel to each other.
Alternatively shape, the ring body of described dust retaining ring is taper ring body, and the dust-break end of outer outlet body and the ring body of dust retaining ring are parallel to each other.
beneficial effect
Roller turntable bearing of the present utility model has dust-proof cover, and dust-proof cover is arranged on seal ring outside, and dust-proof cover can effectively prevent large particle dust and other impurities from destroying the sealing mechanism of bearing, thus improves the working life of bearing.
