Abstract
The utility model discloses a cross pin roller type slewing bearing. The cross pin roller type slewing bearing comprises an inner ring and an outer ring, wherein an annular raceway is arranged between matching surfaces of the inner ring and the outer ring, a cross section of the annular raceway is quadrilateral, a plurality of pin rollers are arranged in the annular raceway and distributed in a ring shape along the annular raceway, an annular groove is respectively arranged between the matching surfaces of the inner ring and the outer ring above the annular raceway and below the annular raceway, and an annular sealing strip is arranged in each annular groove. An oil hole leading to the annular raceway is arranged on the outer ring, a nozzle is arranged on the outer ring, and a gear ring is arranged on an outer wall of the outer ring. The cross pin roller type slewing bearing has a reasonable structure; the shape of the annular raceway between the inner ring and the outer ring of an existing slewing bearing is changed, original rollers are replaced by the pin rollers, and therefore bearing capacity of the slewing bearing is effectively enlarged; and the cross pin roller type slewing bearing is widely used in the occasions that the size of a host structure is limited and large bearing capacity is needed.
Description
Technical field
The utility model relates to the pivoting support field, is specifically related to a kind of decussation roller formula pivoting support.
Background technique
Pivoting support is turntable bearing again, is also referred to as: swivel bearing, the supporting of circling round.Pivoting support is used very extensive in real industry, is called as " joint of machine ", is need do relative rotation motion between the two articles, need bear the mechanical necessary important transmission original paper of axial force, radial force, tilting moment again simultaneously.Along with developing rapidly of mechanical industry, pivoting support has obtained using widely in ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial machinery people, rock tunnel(ling) machine, revolving stage lamp industry.
Be provided with ring raceway between the fitting surface of the inside and outside circle of pivoting support; Realize rotation motion through the ball that is arranged in the ring raceway mostly between the inside and outside circle of pivoting support; But the bearing capacity of this pivoting support is limited, and can not use in physical dimension has restriction to require again on the big device of bearing capacity.
The model utility content
The purpose of the utility model provides a kind of decussation roller formula pivoting support, changes the shape of the ring raceway between the inside and outside circle fitting surface of pivoting support, and changes original ball into roller, improves the bearing capacity of pivoting support.
The technological scheme of the utility model is following:
A kind of decussation roller formula pivoting support; Include inside and outside circle; It is characterized in that: be provided with the ring raceway that the cross section is square between the fitting surface of said inside and outside circle; A plurality of rollers that distribute ringwise along ring raceway are arranged in the said ring raceway, be positioned between the fitting surface of inside and outside circle of ring raceway upper and lower and be respectively equipped with annular groove, be provided with annular sealing strip in the described annular groove; Described outer ring is provided with the oil hole that leads to ring raceway and oil nozzle is installed, and the outer wall of said outer ring is provided with gear ring.
Described decussation roller formula pivoting support, it is characterized in that: the upper and lower end of said outer ring outer wall upper ring gear is respectively equipped with chamfering.
The beneficial effect of the utility model:
The utility model is rational in infrastructure; Changed the shape of the ring raceway between the inside and outside circle fitting surface of original pivoting support; And change original ball into roller, and effectively raise the bearing capacity of pivoting support, receive the restricted big occasion of bearing capacity that requires again of physical dimension adaptable across main frame.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1; A kind of decussation roller formula pivoting support; Include inside and outside circle 1,2, be provided with the ring raceway that the cross section is square between the fitting surface of inside and outside circle 1,2, a plurality of rollers 3 that distribute ringwise along ring raceway are arranged in the ring raceway; Be positioned between the fitting surface of inside and outside circle 1,2 of ring raceway upper and lower and be respectively equipped with annular groove, be provided with annular sealing strip 4 in the annular groove; Outer ring 2 is provided with the oil hole 5 that leads to ring raceway and oil nozzle 6 is installed, and the outer wall of outer ring 2 is provided with gear ring 7.
The upper and lower end of outer ring 2 outer wall upper ring gears 7 is respectively equipped with chamfering 8.
Claims (2)
