Where is the pitch line of a timing belt located?

The pitch line of a timing belt is located at the neutral line. The neutral line represents the point where the tension in the belt is balanced, and it is critical for the effective meshing of the belt's teeth with the sprockets. This positioning allows for precise timing and synchronization of components, which is essential for applications where exact timing is vital, such as in automotive engines or machinery with high accuracy requirements.

The pitch line is where the effective engagement of the belt's teeth occurs as it wraps around the pulleys or sprockets. Proper identification of the pitch line ensures that the belt operates smoothly with minimal wear and that the power is transmitted efficiently. This understanding is fundamental for millwrights and technicians working with mechanical systems that utilize timing belts.
