MULTIPLE-ROW THRUST CONICAL ROLLER BEARING

Japanese Patent JPS5934019

A

PURPOSE:To avoid a differential slide of a conical roller by setting an intersecting point of generating lines of planes of orbits of inner and outer races of a bearing and a cone center of the conical roller in such a manner that at least the intersecting point of the generating lines of the planes of orbits is offset from the central axis of the bearing. CONSTITUTION:A bearing comprises an inner race formed by fitting a countershaft 1 to a rotary shaft and bringing collars 42, 43 into contact with both side end surfaces thereof to be positioned and fixed, and a conical roller 48 rotatably interposed between both side end surfaces of the inner race and the plane 45 of an orbit of an outer race 44. In this case, an intersecting point P2 of generating lines of planes 41a, 45 of orbits of the inner race 41 and the outer race 44 is set to be on the left side of the central axis O-O, and the cone center P1, of the conical roller 48 is set to be on the right side of the central axis O-O. In this arrangement, an angle eta formed by the generating lines of each plane 41a, 45 of an orbit is smaller than the conical angle 2beta of the conical roller 48 by an angle theta of inclination of the inner race 41 so as to prevent the occurrence of a differential slide between the rolling surface of the conical roller 48 and the planes 41a, 45 of orbits.
