Rolling wheel design features a design: the thread diameter of which should be on the rise angle is equal to the thread diameter of the workpiece on the rise angle. 2: tg rolling wheel helix angle = lead (np) / (outer diameter of the rolling wheel teeth D- high H) * 3.142 tg ball screw pitch of the helix angle = p / (d- tooth outer diameter ball screw deep h) * 3.142 (example: 3.175 to take the ball deep tooth 1.28) rolling machine rolling wheel machining, diamond straight thread, steel sleeve production technology because some enterprises should be improved production technology, production will come out straight thread the following phenomena: (1) only end threaded plug screwed in more than 3P (P is the pitch). (2) the length and diameter size does not meet the design requirements. (3) GO only regulation by thread trails. (4) there is a crack. (5) through the end of the threaded plug screwed into the connection can not be successfully and achieve the ends screwed sleeve length.
