Abstract
The utility model discloses a kind of pivoting support bearing larger axial force, include outer ring and the L-type inner ring of height arrangement straggly, annular bearing race is provided with between L-type inner ring and the circumferential fitting surface of outer ring, the steel ball one that multiple annularly bearing race distributes ringwise is provided with in annular bearing race, it is characterized in that: be also provided with plane annular raceway between the axial fitting surface of the end face of L-type inner ring and outer ring, in plane annular raceway, be provided with multiple steel ball two be of moderate size distributed ringwise along plane annular raceway.The utility model is rational in infrastructure, except the annular bearing race be provided with between the circumferential fitting surface of the inside and outside circle of original pivoting support, cycle surface and inner ring end face increase plane annular raceway, improve the axial carrying capacity of pivoting support, outer ring reduces greatly relative to the amount of deformation of inner ring, improves the contact situation of outer ring and other driving component fitting surface.Be widely used in the occasion such as lorry-mounted crane, truck-mounted crane, substantially increase the working life of pivoting support.
Description
Technical field
The utility model relates to pivoting support field, is specifically related to a kind ofly bear the but very little pivoting support of larger axial force amount of deformation.
Background technique
Pivoting support is turntable bearing again, holds also referred to as swivel bearing or circumflex branch.Pivoting support is applied very extensive in real industry, and being called as in " joint of machine ", is need between two articles to do relative rotation motion, needs again the necessary important transmission original paper of machinery simultaneously bearing axial force, axial force, tilting moment.Along with developing rapidly of machinery industry, pivoting support is widely applied in industries such as ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial robot, rock tunnel(ling) machine, playground equipments.
Ring raceway is provided with between the fitting surface of the inside and outside circle of pivoting support, mostly rotation motion is realized by the ball be arranged in the ring raceway of circumference between the inside and outside circle of pivoting support, but the bearing capacity of this pivoting support is limited, can not be used in that physical dimension is restricted to be required again on the device that bearing capacity is large.
Model utility content
The purpose of this utility model is to provide a kind of pivoting support bearing larger axial force, except the annular bearing race between the circumferential fitting surface of the inside and outside circle of original pivoting support, adds one group of plane raceway, substantially increases the axial carrying capacity of pivoting support.
The technical solution of the utility model is as follows:
A kind of pivoting support bearing larger axial force, include outer ring and the L-type inner ring of height arrangement straggly, annular bearing race is provided with between described L-type inner ring and the circumferential fitting surface of outer ring, the steel ball one that multiple annularly bearing race distributes ringwise is provided with in described annular bearing race, it is characterized in that: be also provided with plane annular raceway between the axial fitting surface of the end face of described L-type inner ring and outer ring, in described plane annular raceway, be provided with multiple steel ball two be of moderate size distributed ringwise along plane annular raceway; Described outer ring is also provided with annular groove, and described annular groove is positioned at above annular bearing race, is provided with annular sealing strip in it; Described outer ring is also provided with the oil hole leading to annular bearing race and plane annular raceway, in described oil hole, oil nozzle is installed.
The end face of described L-type inner ring and outer ring is provided with mounting hole respectively.
The outer wall of described outer ring is provided with gear ring.
The size of described steel ball two is determined according to the distance between the axial fitting surface of end face and outer ring of the size of plane annular raceway and L-type inner ring.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, except being provided with except annular bearing race between the circumferential fitting surface of the inside and outside circle of original pivoting support, one group of plane annular raceway is increased between L-type outer ring and inner ring axial end, when physical dimension is less, greatly can improve the axial carrying capacity of pivoting support, outer ring reduces greatly relative to the amount of deformation of L-type inner ring, effectively improves the contact situation of outer ring and other driving component fitting surface.Be widely used in the occasion such as lorry-mounted crane, truck-mounted crane, substantially increase the working life of pivoting support.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
