Cam Mechanism

摘要

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).

主权项

1. An assembly comprising:
a first body comprising at least one follower element; an outer body defining an axis and comprising at least one guide structure configured to engage with the at least one follower element for confining travel thereof to substantially parallel the axis and guiding positioning of the first body between a first position and a second position; and a cam module positioned between the first body and the outer body, the cam module configured with the outer body for rotational displacement substantially about the axis, the cam module defining at least one pathway having a profile, the least one pathway being shaped and dimensioned for travel of the at least one follower element therealong during rotational displacement of the cam module about the axis, wherein travel of the at least one follower element along the at least one pathway during rotational displacement of the cam module linearly displaces the at least one follower element along the at least one guide structure and parallel the axis to thereby displace the first body between the first position and the second position.
