5 Questions
- What is the helix angle in terms specific to screws?
The helix angle in terms specific to screws can be found by unraveling the helix from the screw, representing the section as a right triangle, and calculating the angle that is formed.
- What is the formula to express the helix angle?
The formula to express the helix angle is: $\text{Helix angle} = \arctan \left({\frac {2\pi r_{m}}{L}}\right)$ where $L$ is the lead of the screw or gear and $r_m$ is the mean radius.
- What is the helix angle measured in?
The helix angle is measured in degrees.
- What distinguishes the helix angle from the lead angle?
The helix angle references the axis of the cylinder, while the lead angle references a line perpendicular to the axis. The helix angle is the geometric complement of the lead angle.
- What are some common applications of the helix angle?
Common applications of the helix angle are screws, helical gears, and worm gears.
