Example 2
The present embodiment provides a small tooth difference displacement transmission structure for chopper phase adjustment, as shown in fig. 1, on the basis of embodiment 1, a small tooth difference transmission chain includes an adjusting gear 7 disposed on an eccentric shaft 5, the adjusting gear 7 is simultaneously meshed with a first gear 8 and a second gear 6, that is, the adjusting gear 7 is simultaneously meshed with internal teeth of the first gear 8 and the second gear 6, the first gear 8 is located at one end of the eccentric shaft 5, the other end of the eccentric shaft 5 is connected with a second bevel gear 4, a tooth difference exists between the first gear 8 and the second gear 6, the second gear 6 is meshed with a third gear 9, that is, the second gear 6 is meshed with the third gear 9 through external teeth, and the third gear 9 is disposed on a fixed shaft 10, wherein the first gear 8 is an input end of the transmission structure, and the third gear 9 is an output end of the transmission structure.
Example 3
The embodiment provides a little tooth difference transmission structure that shifts for hacking knife phase adjustment, on the basis of embodiment 2, all is provided with the bearing between eccentric shaft 5 and adjusting gear 7, between eccentric shaft 5 and first gear 8, between eccentric shaft 5 and second gear 6, is provided with the bearing between third gear 9 and fixed axle 10.
The working principle of the small tooth difference deflection transmission structure for adjusting the phase of the hacking knife is as follows:
when the input end transmits torque, the servo motor 1 is kept still, and the first gear 8 and the second gear 6 keep the transmission ratio 1 because the adjusting gear 7 is simultaneously meshed with the inner teeth of the first gear 8 and the second gear 6: 1 and the transmission ratio is kept constant, the transmission ratio of the first gear 8 and the third gear 9 is unchanged, i.e. the phase of the input end and the output end is constant.
When the input end does not transmit torque, the first gear 8 is fixed, the rotation of the servo motor 1 is transmitted to the eccentric shaft 5 through the first bevel gear 3 and the second bevel gear 4, and at the moment, the eccentric shaft 5 drives the adjusting gear 7 to be meshed with the first gear 8 and the second gear 6 for rotation. Because the number of teeth difference exists between the internal teeth of the first gear 8 and the internal teeth of the second gear 6, when the adjusting gear 7 rotates for a certain angle, the angle difference can be generated between the first gear 8 and the second gear 6, the first gear 8 at the input end is fixed at the moment, and the third gear 9 at the output end can realize rotation through the angle difference to complete phase adjustment.
When the input end transmits torque, the rotation of the servo motor 1 can change the transmission ratio of the first gear 8 at the input end and the third gear 9 at the output end, so that stepless regulation of the phase of the sixteen-open hacking knife in the working process is realized.
According to the above, the small tooth difference deflection transmission structure for adjusting the phase of the hacking knife is a sixteen-open hacking knife phase adjusting device with simple structure, good reliability and high adjusting precision, and can realize stepless adjustment of the phase of the sixteen-open hacking knife in the working process of the folding equipment, and improve the working efficiency.
