Abstract
PURPOSE: To titled straightener in which the roll-thrust bearing can be retained within a diameter similar to that of the roll, by constituting as follows; one face of the seat plate is contacting with the end face of the roll journal; another face is contacting with plural small steel balls; a large diameter steel ball circumscribes these small steel balls; a part of this large diameter steel ball is projected from the end face of the cylindrical retainer and is supported by the face of the dead load receiver.
CONSTITUTION: The thrust force F, generated in the work roll 1 while the straightening work, is transmitted from the roll 1 to the seat plate 2 through the roll journal end 1', and is transmitted to three small diameter steel balls 3 being distributed uniformly to three balls 3; depending on the balance between forces acting on the cylindrical retainer 6 and the large diameter ball 4, the small diameter balls 3 transmit the force (F/n).tanθ to the cylindrical retainer 6, and the force (F/n). (1/cosθ) to the large diameter ball 4 respectively. In above formulas, (n) is the number of small diameter steel balls 3, that is 3 in this case. The large diameter steel ball 4 composes three forces given by small diameter steel balls 3 into a composite force equal to the thrust force F generated in the roll 1, and transmits this force to the face of dead load receiver 5. The large diameter steel ball 4 does not rotate, however, the samll diameter steel balls 3 rotate and move round making the rolling contact, so that the bearing of good wear resistance can be obtained.
