Abstract

Provided is an endless metal ring manufacturing method for manufacturing an endless metal ring by carrying out a barrel polishing step for polishing the endless metal ring by using a barrel of a resin material, a rolling step for rolling the endless metal ring which was cleaned, and a nitriding step for nitriding the endless metal ring which was rolled, wherein after the barrel polishing step and before the rolling step, provided is a resin removing step for removing resin that has adhered to the endless metal ring.

First claim

1 . An endless metal ring manufacturing method including:
a barrel polishing step of polishing an endless metal ring by use of a barrel made of resin; a rolling step of rolling the endless metal ring having been washed; and a nitriding step of nitriding the rolled endless metal ring, wherein the manufacturing method further includes a resin removal step of removing the resin that has adhered to the endless metal ring.

2 . The endless metal ring manufacturing method according to claim 1 , wherein the resin removal step is performed after the barrel polishing step and before the rolling step.

3 . The endless metal ring manufacturing method according to claim 1 , wherein the resin removal step includes soaking the endless metal ring in a decomposition treatment liquid to remove the resin.

4 . The endless metal ring manufacturing method according to claim 1 , wherein the resin removal step includes causing a fluid to collide against a surface of the endless metal ring to remove the resin.

5 . The endless metal ring manufacturing method according to claim 1 , wherein the resin removal step includes soaking the endless metal ring into a liquid to perform ultrasonic washing.

6 . The endless metal ring manufacturing method according to claim 5 , wherein the resin removal step includes rotating the endless metal ring to wash the endless metal ring.

7 . An endless metal ring resin removal device configured to wash and hold an endless metal ring, wherein the endless metal ring resin removal device includes:
a holding tool for holding the endless metal ring; a rotation mechanism configured to rotate the endless metal ring in a circumferential direction of the endless metal ring with the holding tool; a washing tank filled with a liquid for ultrasonic washing of the endless metal ring; and an ultrasonic wave generator for performing the ultrasonic washing.

8 . The endless metal ring resin removal device according to claim 7 , wherein the ultrasonic wave generator is operated while the rotation mechanism rotates the endless metal ring in the circumferential direction to remove resin having adhered to a surface of the endless metal ring.
