| 11. | The helix angle of the Helical Camshaft is probably always going to be around 30 to 35 degrees.
|
| 12. | Instead, the lead angle, which is equal to 90 degrees minus the helix angle, is given.
|
| 13. | Fine threads are less likely to vibrate loose as they have a smaller helix angle and allow finer adjustment.
|
| 14. | The efficiency can be plotted versus the helix angle for a constant friction, as shown in the adjacent diagram.
|
| 15. | The maximum efficiency is a helix angle between 40 and 45 degrees, however a reasonable efficiency is achieved above 15?
|
| 16. | The main components of a rotary NiTi file are tip size, taper, flutes, helix angle and measuring stop.
|
| 17. | In its typical parallel arrangement, meshing helical gears requires that the helix angles are of the same magnitude and cut oppositely.
|
| 18. | The helix angle references the axis of the cylinder, distinguishing it from the lead angle, which references a line perpendicular to the axis.
|
| 19. | The friction value is dependent on the materials of the screw and interacting nut, but ultimately the efficiency is controlled by the helix angle.
|
| 20. | The lobe has a helical slot machined into it that has a helix angle of about 35?relative to the rotational axis of the camshaft.
