利用蜗杆型珩轮珩齿,是近年来发展的齿轮精加工方法之一,采用这种工艺,投资少见效快。采用插(滚)—热—蜗杆珩,可使淬火后的8～9级精度齿轮稳定提高到珩后7级(GB179-83)。蜗杆型珩轮珩齿加工,是利用含有磨料的单头珩轮,在与被珩齿轮啮合作自由传动的过程中,借齿面间的一定珩齿压力和较高的珩齿速度(20m/s)与工件相对滑移而产生切削力来进行切削。蜗杆型珩轮精度高,珩轮直径大,螺纹升角很小,所以其造形误差较小。
The use of worm-type honing honing gear is one of the gear finishing methods developed in recent years, the use of this technology, investment inefficient and quick. Insert (roll) - hot - worm honing, can be quenched after the 8 to 9 precision gear stability increased to Heng seven (GB179-83). Worm-type honing gear processing, is the use of abrasive-containing single-head honing wheel, with the hinging gear meshing for free transmission process, by a certain honing tooth surface pressure and high honing speed (20m / s) slipping relative to the workpiece to produce cutting force for cutting. Worm type honing wheel high precision, honing wheel diameter, thread angle is very small, so its shape error is small.
