The spheroconical cams are a development and optimization of traditional cylindrical cams, designed to ensure greater efficiency, precision, and compactness in mechanical systems.
The main difference between a spheroconical cam and a cylindrical one lies in the orientation of the follower roller (C). In a cylindrical cam, the roller is parallel to the output rotation axis, while in the spheroconical cam, the rotation axis of roller C always passes through the intersection point of the cam rotation axis B and the output rotation axis A.
In spheroconical cams, unlike conventional cylindrical cams, the contact surface between the cam profile and the follower remains constant, engaging the full height of the roller. In cylindrical cams, this contact height varies during rotation, which reduces the effective contact area. To compensate, engineers must increase the cam diameter, which limits machine compactness and speed.
The optimized contact between the cam and follower eliminates axial sliding, resulting in lower friction and improved:
efficiency,
reliability,
service life,
operating speed,
and reduced maintenance.
With roots dating back to the 1950s, Colombo Filippetti S.p.A. is a renowned specialist in the design and manufacturing of high-precision cams. Through constant innovation and deep technical expertise, the company stands today as an international benchmark for precision mechanical solutions.
