Swing bearing ( “drunk bearing” ; incorrect name for swivel bearing also occurs) is a mechanism used in mechanical engineering to convert the movement of a rotating shaft into the reciprocating motion of a driven sleeve parallel to the axis of the shaft [1] . The closest analogue is the faceplate mechanism .
Content
Design
The shaft has a groove acting as an inner ring of the bearing . The plane in which this groove is located is at an angle to the axis of the shaft [1] . The outer ring of the bearing has a lever located in the plane of the bearing on a straight line passing through the center of rotation and the point of attachment of the lever to the outer ring of the bearing. The lever can only move in a plane passing through the axis of the shaft, since the free end of the lever is brought into the driven sleeve, the movement of which inside a certain segment parallel to the axis of the shaft is provided in one way or another by other structural elements.
The number of reciprocating movements is directly proportional to the number of revolutions. The range of motion is directly proportional to the angle of deviation of the bearing plane from the perpendicular to the axis of the shaft and is directly proportional to the length of the lever.
Application
The swing bearing is widely used in the mechanism of linear arrangement perforators (in the angular arrangement perforators, its function is performed by the KShM , which converts the rotational motion of the shaft into reciprocating motion in a plane perpendicular to the axis of the shaft).
