A projection is arranged between the upper rollway and the intermediate perpendicular rollway, the inner upper ring and the inner lower ring are respectively provided with a horizontal rollway, the inner upper ring is provided with a perpendicular rollway, the upper rollway and the lower rollway of the outer ring respectively correspond to the horizontal rollways of the inner upper ring and the inner lower ring, horizontal rollers are arranged on the rollways, the intermediate perpendicular rollway of the outer ring corresponds to the perpendicular rollway of the inner upper ring and is provided with a perpendicular roller, the horizontal rollers and the perpendicular roller are all provided with spacers, and sealing strips located on the outer sides of the rollways are arranged among matching surfaces of the outer ring, the inner upper ring and the inner lower ring. The external tooth compact type special-shaped three-row roller slewing bearing is compact in structure, large in bearing capacity, stable in running and reliable and practical.
Description
Technical field
The utility model relates to a kind of pivoting support field, mainly is the special-shaped three row's roller pivoting supports of a kind of external tooth compact type.
Background technique
Pivoting support is used very extensive in modern industry, be called as " joint of machine ", it mainly is widely used in lifting charging crane, harbour machinery, mining machinery and CT machine standing wave therapeutic equipment, nautical instrument, radar antenna base, missile launcher or the like aspect.But just need on the conditional big machinery of some structure spaces that bearing capacity is big, the pivoting support of compact structure.
The model utility content
Technical problem to be solved in the utility model provides the special-shaped three row's roller pivoting supports of a kind of external tooth compact type, is mainly used on the conditional big machinery of structure space, and its bearing capacity is big, compact structure, and running is steadily.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The special-shaped three row's roller pivoting supports of a kind of external tooth compact type, include outer ring, interior Shang Quan and Nei Xiaquan, the Shang Quan and the interior outside of circle down in the outer ring is enclosed within, the outer ring is provided with raceway, and the following raceway of last raceway horizontal parallel and be clipped in intermediate vertical raceway between the upper and lower raceway, and last raceway and intermediate vertical raceway have been asked a convex hole platform; Interior Shang Quan and interiorly down be respectively equipped with horizontal raceway on the circle encloses on interior and also is provided with vertical raceway; The upper and lower raceway of outer ring is corresponding with the horizontal raceway of interior Shang Quan and interior circle down respectively, and on raceway, be separately installed with horizontal roller, the intermediate vertical raceway of outer ring is corresponding with the interior vertical raceway of going up circle and vertical roller is installed, and is equipped with spacing block on described horizontal roller and the vertical roller; Be provided with the Stamping Steel Ribbon that is positioned at the raceway outside between the fitting surface of outer ring and interior Shang Quan, interior circle down.
Protrusion between last raceway and intermediate vertical raceway is roller and the spacing block that is used for supporting raceway, in order to reduce the space of whole three row's roller pivoting supports, reaches compact effect.
The utility model has the advantages that:
The utility model compact structure, bearing capacity is big, and running is steadily, and is reliable and practical.
