JOINT OF UNIVERSAL SPINDLE Russian patent published in 1995 - IPC

FIELD: rolling mill equipment. SUBSTANCE: spindle joint has bush 2 inserted into draw plate 1. Barrel-shaped rolling solids of revolution 3 are disposed in semicylindrical notches of draw plate 1 and bush 2. The axial interaction of draw plate 1 and bush 2 is exercised by pressing rod of piston 6 to disk 5 by means of spring 4. The retention of lubricant in the joint cavity is ensured with thickening ring 9. Bayonet ring 7 serves as a prop during the travel of bush 2 to its extreme position. The peculiarity of the construction is in making the device for the axial fixation of the rolling solids of revolution in the form of one-sided beams made at least on one face end of the very rolling solids of revolution. A ring-shaped recess into which the mentioned beads go is made on bush 2. The bead outside is spherical, the bead inside is two-sided. The rib for the side conjugation forms with the cross-sectional axle of the joint an angle equal to half the angle of the joint skewing. As a result the rolling solids of revolution roll freely in the notches of the draw plate and the bush in case the joint is twisted and are fixed from the displacement in the axial direction. EFFECT: simpler design and enhanced reliability at the heavy duties of loading. 2 cl, 5 dwg
