| 摘 要： | 根据齿轮啮合原理，设计了一种新型差速啮合异向双螺杆捏合机螺杆的端面齿形，该齿形全部由圆弧及圆弧包络线组成，齿形曲线呈光滑连续，齿形上无尖点存在，有利于刀具的设计和磨削加工．同时针对所设计的螺杆，根据铣刀成形原理，计算了铣削加工所需成形盘铣刀的刃形，并根据间隙要求对其进行了修正．用得到盘形铣刀的刃形去加工某些形状的工件，有可能产生过切现象，因此在计算完铣刀刃形后，还对铣刀刃形进行了过切校验，确保所设计的盘形铣刀不会过切螺杆齿形．

| Abstract: | Basing on the theory of engagement, a design has been done for a new type of counter-intermeshing twin-screw kneader. Profile of the screw includes arcs and its envelope lines, and the profile is smooth and continuous without cuspidal points. Milling cutter blade profiles also have been calculated and corrected for manufacturing the helical parts designed and getting the clearance acquired. There may be interference between the cutter and the workpiece, so interference check must be done to insure the milling cutter and screw will not be interfered. |
