Description

F16C covers shafts, bearings, pivots, and rotary support elements that enable mechanical power transmission and rotation in machinery. The class encompasses rigid and flexible shafts, crankshaft components, pivotal connections, and all bearing types designed to support rotational or oscillating motion. Notably excluded are gearing, couplings, clutches, and brakes, which fall under separate classifications despite their role in power transmission systems. This subclass forms the structural foundation for rotating machinery across industrial, automotive, and mechanical engineering applications.

Scope Notes

Glossary: rotary engineering element rotary engineering elements any engineering element, other than a rotating element used in gearing, clutches, couplings or brakes, which rotates so far as its features are affected only by the fact that it rotates. bearing bearings a component of a machine or mechanism that is positioned between two relatively movable elements of the machine or mechanism and that has a surface formed for sliding or rolling contact with these elements when they move relative to each other for the sole function of reducing the friction that would otherwise result from their relative movement. connecting-rod or link pivoted at both ends a reciprocating or oscillating elongated member of a machine or mechanism that is intended to be pivotally connected to and positioned between two relatively movable elements of the machine or mechanism for the purpose of transmitting force or conveying motion between the elements when it reciprocates or oscillates. crankshaft crankshafts a shaft with one or more cranks for turning reciprocating or oscillating motion into rotary motion. flexible shaft flexible shafts an elongated member, normally a cylindrical rod, that is bendable along its length and rotates about its longitudinal axis to transmit torque or convey motion. Bowden cable Bowden cables a control cable consisting of an elongated member enclosed within a housing and that is bendable along its length and shifts along its longitudinal axis relative to its housing to transmit motion or force. roll, drum, disc roll drum disc rolls drums discs an element of a machine or mechanism in the form of a roller that has a generally curved surface that contacts work and revolves about its axis when the work shifts relative to it. shaft shafts an elongated member, normally a cylindrical rod, that rotates about its longitudinal axis to transmit torque or convey motion from a gear or other rotary body supported by it to another part of its machine or mechanism. | Limiting references: Piston-rods, i.e. rods rigidly connected to the piston Control cables for flexible medical endoscopes Control cables for flexible technical endoscopes Connecting-rods .
