When the cam rotates around an axis, it can transmit the constant-speed circular motion of the cam to the driven contact, and the follower reaches Regular motion of expected continuous or discontinuous motion. Cams are essential for automated equipment 'widely used in a variety of machinery' such as machine tools, looms, printing presses, automatic lathes or sewing machines. The types include plate cams, grooved cams and cylindrical cams. The plate cam is designed such that the follower moves in the plane of the vertical camshaft, and the grooved cam moves the follower on the groove of the plate cam surface, and the cylindrical cam makes the slave The moving member is actuated on a groove formed by the peripheral wall of the cylinder. In the case of a cylindrical cam, there is a kind of winding cam [Sp〇〇Winding Cam] which is mainly used in a fishing rod 'woven bag machine, etc.', and a cross-spiral is provided on the cylindrical body. The groove is as follows: The follower set is set in the contour curve groove. When the main body of the lane is rotated in one direction, the follower can be driven to move in the (4) curve groove. 201213220 However, the winding cam applied to the reel in the market today has great fluency in guiding the follower movement. For example, in the case of a reel for a fishing rod, when the grip is rotated to drive the winding cam to rotate Further, when the follower of the actuating winding cam reciprocates in the intersecting spiral groove of the winding cam, since the design of the intersecting spiral groove of the winding cam is not smooth or the design of the pause angle is improper, the follower is easily caused to be contoured. Excessive friction occurs when the curved groove moves, and a large torque is required to drive the missing movement of the follower, and when the driven member drives the winding and retracting, the follower does not smoothly move, and the winding is extremely likely to be caused. Intertwined and entangled. The reason is that the inventors have in view of the lack of smooth design of the existing reel cam cam profile groove and the improper design of the pause angle, which makes the actuating follower more laborious and unsmooth, and it has been in the related field for many years. The manufacturing, design experience and knowledge assistance, and through many ingenuity, research and development of the present invention.
