In this subclass, the following terms or expressions are used with the meaning indicated:
Rotary engineering element | 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 | 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 | A shaft with one or more cranks for turning reciprocating or oscillating motion into rotary motion. |
Flexible shaft | 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 | 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 | 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 | 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. |
connecting-rod | conrod, con rod, piston rod |
sliding bearing | sliding contact bearing, slide bearing, plain bearing, gliding bearing, friction bearing, hydrodynamic bearing, fluid dynamic bearing |
anti-friction bearing | antifriction bearing, roller bearing, rolling bearing, rolling contact bearing, ball bearing, needle bearing, rolling elements bearing |
