5 Questions
What is the helix angle in mechanical engineering?
The helix angle is the angle between any helix and an axial line on its right, circular cylinder or cone.
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.
How is the helix angle related to the lead angle?
The helix angle is the geometric complement of the lead angle.
How can the helix angle be found in terms specific to screws?
The helix angle 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 mathematical expression for the helix angle?
The helix angle can be expressed as: $\text{Helix angle} = \arctan \left(\frac{2\pi r_{m}}{L}\right)$ where $l$ is the lead of the screw or gear and $r_m$ is the mean radius.
