Abstract
Official abstract text for this publication.
A method of manufacturing a constituent member of a constant-velocity joint includes: performing plastic working; and performing hardening of a material. The plastic working is performed with a material of the constituent member heated to a predetermined working temperature range. The hardening of the material is performed by utilizing heat applied for heating to the working temperature range in performing the plastic working as heat for the hardening of the material and cooling the material after performing the plastic working.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of manufacturing a constituent member of a constant-velocity joint, comprising: performing plastic working on a material of the constituent member with the material heated to a predetermined working temperature range; and performing hardening of the material by utilizing heat applied for heating to the working temperature range in performing the plastic working as heat for the hardening of the material and by cooling the material after performing the plastic working. 2 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 1 , further comprising: applying a paint to the material after performing the hardening; drying the paint on the material in a predetermined drying temperature range after applying the paint; and performing tempering of the material by utilizing heat applied for heating to the drying temperature range in the drying as heat for the tempering of the material and by cooling the material. 3 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 2 , further comprising performing finish turning of the material after performing the hardening and before applying the paint. 4 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 1 , further comprising: performing tempering of the material after performing the hardening; and performing finish turning of the material after performing the tempering. 5 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 1 , wherein a temperature of the material immediately after the plastic working is completed in performing the plastic working is a temperature that is equal to or higher than a transformation point of the material. 6 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 1 , further comprising heating the material in an inert gas atmosphere before performing the plastic working. 7 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 1 , further comprising removing scales of the material immediately after performing the hardening. 8 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 1 , wherein the hardening is performed with the material restrained so as to suppress deformation and distortion of the material due to the hardening. 9 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 1 , further comprising correcting the material after performing the hardening so as to remove deformation and distortion of the material due to the hardening. 10 . A method of manufacturing a constituent member of a constant-velocity joint, comprising: performing hardening of a material of the constituent member; applying a paint to the material after performing the hardening; drying the paint on the material in a predetermined drying temperature range after applying the paint; and performing tempering of the material by utilizing heat applied for heating to the drying temperature range in the drying as heat for the tempering of the material and by cooling the material. 11 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 10 , further comprising removing scales of the material immediately after performing the hardening. 12 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 10 , wherein the hardening is performed with the material restrained so as to suppress deformation and distortion of the material due to the hardening. 13 . The method of manufacturing a constituent member of a constant-velocity joint according to claim 11 , further comprising correcting the material after performing the hardening so as to remove deformation and distortion of the material due to the hardening.
