The technical solution of the utility model is as follows:
the conical roller bearing inner ring and outer ring conjoined forging comprises an inner ring forging and an outer ring forging, wherein the lower end face of the inner ring forging and the upper end face of the outer ring forging are molded together, the diameter of the lower end face of the inner ring forging is the same as that of the upper end face of the outer ring forging, and the inner ring forging and the outer ring forging are coaxial.
The outer diameter surface of the inner ring forging piece is an inner ring outer diameter surface straight line section, a first inclined line section, a first arc section, a second inclined line section and a second arc section from top to bottom, and the included angles between the first inclined line section and the second inclined line section and the axial lead of the inner ring forging piece are 5-10 degrees.
The outer ring forging is sequentially provided with an outer ring inner diameter surface arc section and an outer ring inner diameter surface inclined line section from top to bottom, and the included angle between the outer ring inner diameter surface inclined line section and the axial lead of the outer ring forging is 65-70 degrees.
The outer diameter surface of the outer ring forging piece is a vertical straight line.
The inner diameter surface of the inner ring forging piece is sequentially provided with an inner diameter surface straight line segment and an inner diameter surface arc segment from top to bottom.
The utility model has the beneficial effects that:
the inner ring forging and the outer ring forging are forged into a whole, so that the production procedures are reduced, the material consumption is reduced, the production cost is saved, and the machining allowance is reduced.
