Outer ring member for constant velocity joint and method of manufacturing the member |
摘要 |
An outer ring member for a constant velocity joint is manufactured. An intermediate preformed product 16 having a cup section 21 with an incomplete shape is formed by pressing a large diameter section 14 without applying a low temperature annealing treatment and a lubricating chemical conversion coating treatment. Then, applying a low temperature annealing treatment and a lubricating chemical conversion coating treatment to the intermediate preformed product 16, thereafter a formed product having a cup section 8 provided with ball-rolling grooves 17a to 17f is formed by backward extrusion to the intermediate preformed product 16. Subsequently, the product is ironed before hardening, without applying a low temperature annealing treatment and a lubricating chemical conversion coating treatment to the formed product.
