Title: Method and device for roller burnishing of crank shaft
Inventor: KANAZAWA KOUKA
IPC: B24B39/04
Filed: 1992-12-22
Abstract: PURPOSE:To establish a roller burnishing process for the shank part of a crank shaft, in which the shank ends are prevented from sagging. CONSTITUTION:The shoulder part 7b at each end of a burnishing roller 7 is contracted relative to a thicker column part 7a in the center, and thereby the form of a Japanese drum is generated. The column part 7a is made of a material having high Young's modulus while the shoulder part 7b made of a material of low Young's modulus. The shank part of a crank shaft W is supported by a support roller and rotated. The burnishing roller 7 is rotated, and from the back, a backup roller 8 is pressed so that the roller 7 is pressed to the shank part 1. Because the processing surface pressure of the roller 7 is high in the column part 7a of high Young's modulus and low in the shoulder part 7b, the shank part 1 is precluded from sagging. Because of this special form of roller 7, the shank part 1 can be finished in a recessed form, and it is easy for the shank part 1 to form an oil film and retain, to lead to enhancement of the seizure resistance of the shank part of crank shaft.
