SUPPORTING-AND-BUTT-JOINING SET FOR MODULAR ARTICLES Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: supporting-and-butt-joining set running frame. Mounted on frame is crossmember with fitted on turnable beam with central pivot and load-bearing beam with beds for article module. Turnable beam is installed on lifting hydraulic cylinders 6 and locking jacks through supports 8 and 9 mounted on lifting cylinder pistons 10 and turnable beam through rods 11 fitted in supports by end faces with noses. Rod 11 has spherical supporting surfaces 12 and 13 on its end faces formed to one and the same radius R from one center and end pieces in form of bushings 14 and 15 embracing the surfaces. Outer starting surface of bushings is made in form of involutoid forming involute tooth. Profile of involute of tooth is geometrically referred to spherical surface of rod end faces as pitch circle of gear wheel, diameter D=2R. Support 8 and 9 have flat supporting surface 16 and inclined surfaces 17 formed by faces of inverted tetrahedral truncated regular pyramid. EFFECT: enlarged operating capabilities. 4 dwg
