The indexing cam installed in the input shaft is connected to the output turret, and the cam rollers are radially embedded on the outer surface of the output turret circumference, making linear contact with the taper support ribs of the cam on their corresponding inclined surfaces. When the input shaft rotates, the cam roller rotates the output turret according to the given displacement curve, and together, it rolls along the slope of the rib. In the area where the end face of the rib and cam is balanced, that is, within the static range, the roller is connected to its shaft, but the output turret itself does not rotate. The taper support rib usually touches two or three cam rollers, so that the rotation of the input shaft can be evenly transmitted to the output shaft. If there is an unsmooth condition between the outer surface of the cam with tapered support ribs and the cam rollers, it will damage the splitter. By adjusting the spacing between the shafts, the phenomenon of unsmooth rotation can be eliminated. The preload can be adjusted to approach the elastic zone of the cam roller and cam, and then strengthen the rigidity of the splitter. Its structure and function are the combination of indexing cam and cam roller, which can perform high-speed operation.
1. Indexing cam:
The groove cuts into the outer surface of the cylindrical solid body and is fixed to the cam of the input shaft.
2. Taper support rib:
The tapered rib is located on the circumference of the tapered support rib, between the cam grooves, and linearly touching the circumference of the cam roller.
3. Cam roller:
A finely planned cam roller bearing that can withstand heavy loads.
4. Output turret:
Output turret attached to the output shaft. The indexing cam drives the radial embedded rollers to roll. Its accuracy is a key factor in maintaining the accuracy of the splitter.
5. Number of stops:
The number of stops per rotation of the output shaft.
6. Drive angle (cam indexing angle):
The rotation angle of the input axis requires a indexing motion, and the larger the viewpoint, the smoother the motion.
7. Stop angle:
The viewpoint at which the input axis rotates when the output axis is fixed. The sum of this viewpoint and the driving angle is 360 degrees.
8. rotation number:
Rotation number of the input shaft.
9. Rotating torque:
The maximum torque can be applied to the output shaft in a fixed orientation. If the applied torque is greater than this value, it will damage the splitter.
10. Dynamic torque:
The maximum torque on the output shaft during the indexing period.
