Abstract
The utility model discloses a turntable bearing of a thrust angle contact cylindrical roller, which mainly comprises inner rings (1), a lower-row cylindrical roller (5), an upper-row cylindrical roller (2), a first outer ring (4) and a second outer ring (3), wherein outer teeth are uniformly distributed in the middle of the outer circle of the inner ring (1); roller paths are symmetrically arranged on the outer circle of the inner rings (1) at the upper and lower parts of the outer teeth; each roller path is in an inclined structure; the lower roller path is internally provided with the lower-row cylindrical roller (5) which is pressed and positioned by the first outer ring (4); and the upper roller path is internally provided with the upper-row cylindrical roller (2) which is pressed and positioned by the second outer ring (3). The turntable bearing disclosed by the utility model can bear axial and radial loads, and has great overturning moment and high rigidity; a load bearing capability can be improved under the same space condition and the rigidity and overturning moment bearing capabilities are enhanced; and the requirements on heavy load and great overturning moment are met. The turntable bearing of the thrust angle contact cylindrical roller can be widely applied to fields of a mine heavy machine, a portal crane, a heavy-duty crane and the like.
Description
Technical field
The utility model belongs to the turntable bearing technical field, and what relate generally to is a kind of push angle contact cylindrical roller turntable bearing.The fields such as heavy machinery, portal crane, heavily loaded crane adaptable across the mine.
Technical background
Push angle contact cylindrical roller turntable bearing is mainly used in the carrying heavy load, high tenacity, and fields such as big tilting moment are like mine heavy duty crane, portal crane, slingcart etc.Existing band external tooth biserial four point touching ball slewing bearing; Its rolling element and raceway are the point contact junction structures; The load-carrying ability of being born is high not as the line contact; And gear is arranged on the cylindrical of outer ring, and the ability and the rigidity of bearing load can not satisfy market demands under same spatial condition, like the requirement of heavy loads such as mine excavator, slingcart and portal crane, high rigidity.
Summary of the invention
The purpose of the utility model produces thus, proposes a kind of push angle contact cylindrical roller turntable bearing.This turntable bearing can reach to and radial load, and big tilting moment has high rigidity, improves load bearing capacity down at same spatial condition, increases rigidity and tilting moment ability to bear, satisfies heavy load, the requirement of tilting moment greatly.
The utility model realizes that the technological scheme that above-mentioned purpose is taked is: a kind of push angle contact cylindrical roller turntable bearing comprises inner ring, following line column roller, goes up line column roller, first outer ring and second outer ring; Cylindrical middle part at said inner ring is evenly equipped with external tooth; Be positioned on the inner ring cylindrical at this upper and lower position of external tooth and also be symmetrically arranged with raceway; Each raceway is leaning structure, and in the raceway of bottom, being provided with down, line column roller compresses the location by first outer ring; In the raceway on top, be provided with line column roller and compress the location by second outer ring.
The angle of inclination of said raceway is 35 °～60 °.
The utility model is through being provided with biserial raceway and double-row cylindrical roller structure; And raceway has certain angle of inclination, reaches the target of rolling element and Race Line Contact, has increased load-carrying ability; Make bearing can reach to and radial load, and big tilting moment.Because external tooth is arranged on the middle part of inner ring cylindrical; Like this; Worm gear just can be installed in above the inner ring cylindrical, compares with existing band external tooth biserial four point touching ball slewing bearing, under same spatial condition, can increase substantially load bearing capacity; Increase rigidity and tilting moment ability to bear, satisfy the requirement of field heavy loads such as mine heavy duty crane, portal crane, slingcart, big tilting moment.
Description of drawings
Fig. 1 is the main schematic representation of the utility model structure.
Among the figure: 1, inner ring, 2, go up line column roller, 3, second outer ring, 4, first outer ring, 5, line column roller down.
Embodiment
In conjunction with accompanying drawing, embodiment is elaborated to the utility model.
As shown in Figure 1: the push angle contact cylindrical roller turntable bearing under the present embodiment comprise inner ring 1, two raceways, down line column roller 5, go up line column roller 2, first outer ring 4 and second outer ring 3; Cylindrical middle part at said inner ring 1 is evenly equipped with external tooth; Be positioned on inner ring 1 cylindrical at this upper and lower position of external tooth and also be symmetrically arranged with raceway, thus, on the inner ring cylindrical, form upper and lower two raceways; Each raceway is leaning structure, and the angle of inclination is selected arbitrarily between 35 °～60 °.In the raceway of bottom, be provided with line column roller 5 down, in the raceway on top, be provided with line column roller 2, following line column roller 5 compresses the location by first outer ring 4, and last line column roller 2 compresses the location by second outer ring 3.
Claims (2)
1. a push angle contacts the cylindrical roller turntable bearing; It is characterized in that: it mainly is made up of inner ring (1), time line column roller (5), last line column roller (2), first outer ring (4) and second outer ring (3); Cylindrical middle part at said inner ring (1) is evenly equipped with external tooth; Be positioned on inner ring (1) cylindrical at this upper and lower position of external tooth and be symmetrically arranged with raceway; Each raceway is leaning structure, and in the raceway of bottom, being provided with down, line column roller (5) compresses the location by first outer ring (4); In the raceway on top, be provided with line column roller (2) and compress the location by second outer ring (3).
