In prior art, pivoting support is constant in installation dimension, and by under the effect of eccentric force, it is impossible to improve axial carrying capacity。
Summary of the invention
It is an object of the invention to provide a kind of Special rotating supporting, the positioner on heavy-duty machines people's welding equipment uses, it is intended to improve bearing capacity, improves service precision, alleviates the weight of structure；Meanwhile, stability when pivoting support uses is improved, it is ensured that installation accuracy and welding repetitive positioning accuracy so that it is perfectly combine, reached the instructions for use of specialities。
For reaching above-mentioned purpose, the invention provides a kind of external tooth type crossed roller pivoting support: include inner ring, external toothing and column type roller arranged in a crossed manner therebetween；
Described inner ring upper surface is higher than described external toothing upper surface, and the part that described interior ring outer wall highlights relative to described external toothing arranges the first sealing ring；Described inner ring lower surface is higher than described external toothing lower surface, and described external toothing inwall arranges the second sealing ring relative to the ledge of described inner ring；
Offering raceway in the middle part of described external toothing inwall, described raceway is isosceles right triangle, and vertex angle offers U-type groove；Described raceway right-angle side length is identical with described column type roller height；
It is square groove that described interior ring outer wall circumference offers vertical cross-section, fills sprue in described groove；Described sprue is fixed in inner ring by taper bolt；Described taper bolt conical lower portion is towards described inner ring upper surface；
The raceway of described inner ring and the corresponding described external toothing of sprue outer wall offers isosceles right triangle raceway；Described raceway drift angle is provided with U-type groove；Described raceway right-angle side length is identical with described column type roller height；
Described column type roller adjacent roller cross arrangement, the axis of described adjacent column type roller is in 90 °；
The some connection screwed holes of circumference uniform distribution in the middle part of described inner ring inwall；
The outside wall parallel pivoting support axis direction of described external toothing arranges outer teeth groove, and described outer teeth groove is positioned at the middle and upper part of described external toothing outer wall。
Under optimal way, described inner ring wears hole, some location, and hole, described location is stepped counterbore。
Present invention have an advantage that
1, the rolling element of pivoting support of the present invention is the axis cross arrangement in 90 ° of cylindrical roller adjacent roller；Inside and outside circle is respectively arranged with two raceways, and raceway section is linear；Wherein half roller bears downward axial force, and half bears axial force upwards。
2, present invention optimizes pivoting support structure, alleviate the weight of structure；
3, the present invention is by adjusting the design that pivoting support is installed and positioned hole, improves stability when it uses, it is ensured that installation accuracy, effectively coordinates turntable and fuselage so that it is perfectly combine, reached the instructions for use of specialities。
External tooth type crossed roller pivoting support of the present invention is large-scale high-precision pivoting support, and vertical is installed, and bears 350T load, to control displacement angle while ensureing rotating accuracy, and for heavy-duty machines, people is supporting。
