The invention relates to a synchronous pulley of an automobile electric steering gear. The synchronous pulley comprises a cylindrical body (1), the outer wall of the cylinder body (1) is step-shaped,an inclined arc gear (11) is arranged on the outer wall of the cylindrical body (1), the inner cavity of the cylindrical body (1) comprises an internal thread section (2) at one end and a smooth innerwall section (5) at one end, a transition step is arranged between the internal thread section (2) and the smooth inner wall section (5), and a steering positioning arc straight groove (3) is formedin the junction of the transition step and the smooth inner wall section (5). Compared with synchronous pulleys in the prior art, the synchronous pulley of the invention is fixed in direction during assembling, and improves the assembling efficiency and the product strength performance.
本发明涉及一种汽车电动转向器同步带轮,该同步带轮包括圆柱本体(1),所述的圆柱本体(1)的外壁为台阶型,并在外壁上设有斜圆弧齿轮(11),所述的圆柱本体(1)的内腔包括一端内螺纹段(2)和一端光滑内壁段(5),内螺纹段(2)与光滑内壁段(5)之间设有过渡台阶,并在过渡台阶与光滑内壁段(5)交界处设有转向定位圆弧直槽(3)。与现有技术相比,本发明同步带轮在装配时固定方向,提高装配效率和产品强度性能。
