FIELD: technological processes, casting. ^ SUBSTANCE: invention is related to manufacturing of gear wheels. Gear wheel has sections beveled by means of die forming (111, 121, 131), which are simultaneously formed at corresponding line of crossing of indent surfaces (11), lateral sides (12) and tops of teeth (13) with end surfaces (14) of teeth, through which axial line of wheel is passing, while giving profile to teeth of wheel with surfaces of indents, lateral sides and tops of teeth. ^ EFFECT: suggested gear wheel does not require mechanical treatment, such as removal of burr produced in process of teeth cutting in gear wheels made with standard methods. ^ 12 cl, 19 dwg |
