Abstract

PURPOSE: To easily manufacture a forged rim of a welded construction thick gear with a large diameter and improve reliability of its rigidity by welding a pair of rims devided in the direction of face width of the gear, with ring members between rims.
CONSTITUTION: A rim 6 is symmetrically bisected in the direction of the face width of a gear by intermediate grooves 5 on the rim and is formed by forging special steel. At welding points A corresponding to the location of the intermediate groove 5, each rim and either end face of a soft steel spacer ring 7 are welded into one body of a rim. Soft steel yokes 9 are respectively welded at welding points B, C, on both internal fringes of the rim 6 and a gear boss 8 in the raidal direction of the gear. To develop sufficient rigidity in the direction of the face width, a soft steel yoke 10 is welded between the spacer ring 7 and the gear boss 8 at welding points C, D. The forged rim of a welded construction thick gear with a large diameter can be easily manufactured and improve its reliability of rigidity.
