The cam discs are named after the effective cam angle. For cam discs of series 51, this corresponds to the
switching point angle on the switching point radius of the cam disc.
Any cam angles (15° − 345°) can be supplied as a special design upon request.
The usable revolutions enabled by a cam disc on a GCLS drive shaft, result in the following:
𝑈 =
𝛽 ∗ 𝑖
360°
=
(360° − 𝛼) ∗ 𝑖
360°
= 1 −
𝛼 ∗ 𝑖
360°
U =
usable revolutions
α =
Effective cam angle
β =
Usable cam angle (
β = 360° – α)
i =
gear ratio
