Preferably, the excircle of alignment section is round and smooth, and surface roughness is Ra1.6-Ra0.4.
Preferably, gear wheel section and alignment section are formed in one.
Preferably, the tooth form of gear wheel section is roll threading.
Preferably, the tooth form of gear wheel section is trapezoidal screw.
Preferably, the tooth form of gear wheel section is reticulate pattern.
Preferably, the tooth form of gear wheel section is straight burr.
Preferably, THREAD ROLLING DIES is provided with the installing hole that runs through gear wheel section and alignment section along axis direction.
Preferably, offer keyway on the hole wall of installing hole.
By the one or both ends in gear wheel section round and smooth alignment section is set, when carrying out machining to machined part, rolling tooth process and alignment process can carry out synchronously, production efficiency is provided, simultaneously, can guarantee that cylindricity, axiality or the round tolerance of beating of machining screw, trapezoidal screw, straight burr or one or both ends, reticulate pattern position within 0.005-0.025, satisfy the requirement to Product Precision.
