  1. Abstract : in this paper, a kind of technological scheme for one - step precision forging spur gear with large module is put forward by using positive friction role. experiment, in which commercial pure lead is taken as test material, is done in the special die designed, and force vs. stroke curve is recorded. it is shown that positive friction role can efficiently make a contribution to the filling of the tooth cavity, but increase forming force

    文摘:針對大模數直齒圓柱齒輪,提出了利用積極摩擦一步成形的工藝方案,並用工業純鉛作為試驗材料,在設計的專用模具上進行試驗,記錄了力? ?行程曲線,結果表明:利用積極摩擦作用能夠有效地保證直齒圓柱齒輪精鍛時齒腔充滿,但同時增加了變形力。
