Technical field:
The utility model belongs to the engineering goods technical field, relates generally to the mechanical basic part pivoting support, relates in particular to a kind of pivoting support that loads different rolling elements in two raceways.
Background technique:
Pivoting support is a kind of band gear ring, multiple eyelet, oil circuit and seal arrangement, and can bear the large-scale and super-huge combination bearing of axial force, radial force and tilting moment simultaneously.
The main body of pivoting support is made of inside and outside two high grade manganese steel steel rings.Common single raceway ball-type slewing bearing is its basic structure form, and it is respectively to dig semi-circular grooves one on the corresponding junction plane of Internal and external cycle, lumps together to form a ring-type cylindrical shape raceway, fills up the spherical rolling element of steel in the raceway.Decussation roller formula pivoting support is a kind of special structure form of pivoting support product, it is respectively to dig triangular groove one on the corresponding junction plane of Internal and external cycle, lump together and form a ring-type square raceway, one horizontal one perpendicular cross arrangement steel short cylindrical shape rolling element in the raceway.
Common ball-type slewing bearing is simple in structure, and strength is strong, and large, medium and small type pivoting support all can adopt this kind structure, but its force bearing point is few, and the gap is bigger, and stability and sensitivity are general.Decussation roller formula pivoting support compact structure, force bearing point is many, and the gap is minimum, and stability and sensitivity are very high, the suitable especially very high middle-size and small-size pivoting support of required precision of making of this kind structure, but its ability of bearing great load is obviously not as good as ball formula structure.Therefore, for the design of great type pivoting support, it is a direction of research at present that the structure of ball-type slewing bearing and decussation roller formula pivoting support is mutually combined.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of decussation roller and ball-type slewing bearing to be provided, and it has assembly precision height, good stability and highly sensitive advantage.
The utility model is achieved through the following technical solutions:
A kind of decussation roller and ball-type slewing bearing include inner ring and outer ring, it is characterized in that: the semi-circular grooves and the triangular groove that have mutual corresponding annular on the involutory surface of described inner ring and outer ring; Inner ring is with after the outer ring is nested, and semi-circular grooves is combined to form the cylindrical shape raceway of ring-type, and triangular groove is combined to form the square raceway of ring-type; Be provided with some steel balls in the described cylindrical shape raceway, be provided with spacing block one between the adjacent steel ball, be respectively equipped with arc shaped surface on the described spacing block one with corresponding steel ball profile coupling; Be provided with plurality of rollers in the described square raceway, described roller one horizontal erects and is 90 degree cross arrangements, is respectively equipped with spacing block two between the adjacent roller, is respectively equipped with the arc shaped surface with corresponding roller profile coupling on the spacing block two.
Described a kind of decussation roller and ball-type slewing bearing is characterized in that: described inner ring is a gear ring.
Described a kind of decussation roller and ball-type slewing bearing is characterized in that: described outer ring is a gear ring.
Described a kind of decussation roller and ball-type slewing bearing is characterized in that: the position that described inner ring and outer ring are bonded with each other is provided with seal ring.
The central point of described square raceway and roller thereof, with the central point of cylindrical shape raceway and steel ball thereof all on the medium line of two circle junction planes.Described roller is a short cylinder, the length of short cylinder is slightly less than several of diameters, diameter is slightly less than several of the length of sides of square raceway wall, roller is one horizontal one perpendicular cross arrangement in square raceway, separate with profiling plastic barrier piece two between adjacent two rollers, make the cylndrical surface of every roller have upper and lower two lines to contact the upper and lower wall of square raceway.Described steel ball is a spherosome, sphere diameter is slightly less than several of the diameters of cylindrical shape raceway, steel ball is arranged in the cylindrical shape raceway, separate with profiling plastic barrier piece one between adjacent two steel balls, make the sphere contact raceway wall of every steel ball upper left, upper right, four of lower-lefts, bottom right projection a little, promptly sphere has 4 contact raceway walls.
Described a kind of decussation roller and ball-type slewing bearing is characterized in that: described inside and outside circle is provided with some mounting holes, erection opening and two cover oil-way systems.
No gear ring is provided with two filling holes, plugs and wears pin.Should note two filling holes are up and down staggered, overlapping is provided with, in order to avoid the intensity of the no gear ring of influence.
The utility model suits to adopt when the great type pivoting support of design, and particularly great type main process equipment is both to revolution part required precision height, again sensitivity is required to adopt the utility model than other pairs raceway structure when tight, has more superiority.
The utility model has the advantages that:
