Abstract
The invention discloses a turntable bearing for a thrust angular contact cylindrical roller, which comprises an inner ring (1), a lower row of cylindrical rollers (5), an upper row of cylindrical rollers (2), a first external ring (4) and a second external ring (3), wherein external teeth are uniformly distributed at the middle part of the external circle of the inner ring (1); roller rails are symmetrically arranged on the external circle of the inner ring (1) on the upper and lower parts of the external teeth; each of the roller rails is of an inclined structure; the lower row of cylindrical rollers (5) are arranged in the roller rail at the lower part and are clamped and located by the first external ring (4); and the upper row of cylindrical rollers (2) are arranged in the roller rail at the upper part and are clamped and located by the second external ring (3). The axial and radial loads and a large inclining force moment can be born by the turntable bearing; the turntable bearing has higher rigidity; the load bearing capacity is increased under a same space condition; the rigidity and the bearing capacity for the inclining force moment are increased; the heavy-load and large inclining force moment demands are met; and the turntable bearing is extensively suitable for the fields of mining heavy-duty machinery, port cranes, heavy-duty hoists, and the like.
Description
Technical field
The invention belongs to the turntable bearing technical field, 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 object of the invention 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 present invention 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 present invention 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, 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 structure of the present invention.
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, the embodiment of the invention is elaborated.
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).
2. push angle contact cylindrical roller turntable bearing according to claim 1, it is characterized in that: the angle of inclination of said raceway is 35 °～60 °.
