我厂从联邦德国引进了N19T高速冲床,其高精度分度机构中挂轮与轴的联接采用了如图所示的结构。图示为夹紧状态下的轴孔联接装置。弹簧1通过楔轴3,使楔块2增力后胀紧齿轮7内孔。更换齿轮时下旋螺钉4,待弹簧1被压下后,楔块2对内孔的作用力消除,齿轮即轻松地取出。 I plant imported from the Federal Republic of Germany N19T high-speed punching machine, the high-precision indexing institutions linked to the shaft and the shaft as shown in the structure. The figure shows the shaft hole coupling device in the clamped state. The spring 1 passes through the wedge shaft 3 to force the wedge 2 to expand and expand the inner hole of the gear 7. When changing the gear, lower the screw 4. After the spring 1 is pressed down, the force of the wedge 2 on the inner hole is eliminated and the gear is easily removed.
