Abstract
A novel cam mechanism or assembly is provided by the present disclosure. The cam mechanism can have a cylindrical or barrel shape configuration. The cam mechanism includes a first module or body (also referred to as an inner body), a cam module or body encircling said first module, and a guide module or body (also referred to as an outer body) encircling each of the first module and the cam module. The cam mechanism is configured to translate rotary motion or torque of the cam module about a rotational axis (A) into linear displacement of the first module in a parallel manner along said rotational axis (A). The outer body or guide body encircles each of the cam module and the inner body. The outer body can be a stationary or fixed structure, and can be configured to physically isolate the movable components of the cam mechanism (e.g., the cam module and the inner body).
