Detailed Description
The accompanying drawings disclose, without limitation, a specific structure of an embodiment of the present invention, which is further described below with reference to the accompanying drawings.
As shown in fig. 1, the synchronizing mechanism for the audio drill eccentric wheel of the present embodiment includes two eccentric wheels, two synchronizing wheels, two pressing wheels, three reversing wheels, a synchronizing belt, and a fixed disc. The centers of the first eccentric wheel 1 and the second eccentric wheel 8 are positioned on the same horizontal straight line, and the fixed disk 5 is positioned between the first eccentric wheel 1 and the second eccentric wheel 8. The first synchronizing wheel 2 is fixed on a first eccentric shaft 12 of the first eccentric wheel 1 and the second synchronizing wheel 10 is fixed on a second eccentric shaft 13 of the second eccentric wheel 8, both synchronizing wheels being mounted on the same horizontal plane and at equal distances from the symmetry line of both eccentric shafts. The first pinch roller 3 is fixed on the fixed disc 5 and is positioned at one side close to the first synchronous roller 2; the second pinch roller 6 is fixed on the fixed disk 5 and is positioned at one side close to the second synchronous wheel 10. The first reversing wheel 7 is fixed on the fixed disk 5 and is positioned on the upper part of the vertical center line of the fixed disk 5 so as to provide certain pretightening force; the second reversing wheel 9 and the third reversing wheel 11 are both fixed on the second eccentric wheel 8 and are positioned on one side far away from the fixed disk 5. The double-sided tooth synchronous belt 4 sequentially winds the surfaces of the first synchronous wheel 2, the first pressing wheel 3, the first reversing wheel 7, the second reversing wheel 9, the third reversing wheel 11, the second synchronous wheel 10 and the second pressing wheel 6 to form a circle.
As shown in fig. 2, the shaft end of the first eccentric wheel 1 protrudes out of the plane of the first synchronous wheel 2, and the protruding portion 14 is provided with a positioning groove and a positioning hole 15, wherein the protruding portion 14 in this embodiment is semicircular, and the positioning groove is provided with a step structure. When the synchronous mechanism is installed, a semicircular installation tool 17 is clamped on the step structure of the semicircular convex part 14 at the shaft end and is positioned with the positioning hole 15 at the shaft end face by a bolt, and then the synchronous belt 4 is installed to ensure that the initial phases of the two eccentric wheels are at the same position.
Waist holes are formed in the middles of the first pressing wheel 3 and the second pressing wheel 6, and the pressing wheels are fixed on the fixed disc 5 through shafts and the waist holes and are fastened through nuts. When the synchronous belt 4 is installed, the nut is unscrewed, the positions of the shafts of the first pressing wheel 3 and the second pressing wheel 6 in the waist hole are adjusted, the pressing wheels are firstly moved upwards to enable the synchronous belt 4 to be in a loose state so as to facilitate installation of the synchronous belt, and then the first pressing wheel 3 and the second pressing wheel 6 are adjusted to be moved downwards to enable the synchronous belt 4 to be in a tensioning working state.
