Abstract
A device for the reciprocating linear drive of a part, especially of a scraper at a calender cylinder, comprises a driver connected to the scraper and having two mutually parallel oppositely disposed abutments and an eccentric disposed between the abutments. The eccentric has an outside diameter which is smaller than the distance between the abutments. The eccentric is designed as a double eccentric with a driven inner eccentric fixed to a rotary drive shaft and with a freely movable outer eccentric floatingly mounted to the inner eccentric via an antifriction bearing.

A device for driving a part with a reciprocating linear motion, comprising:
- a pair of abutment members spaced a predetermined distance from one another;
- linking means for rigidly connecting said abutment members to one another and to the part to be driven;
- a first eccentric disposed between said abutment members;
- power source means operatively connected to said first eccentric for rotating same about an axis of rotation;
- and
- a second eccentric disposed between said abutment members and around said first eccentric, said second eccentric being floatingly mounted to said first eccentric so that said second eccentric is substantially freely rotatable with respect to said first eccentric, said second eccentric having a perimeter with a largest diametric dimension smaller than said predetermined distance so that the perimeter of said second eccentric can engage at most one of said abutment members, said second eccentric being mounted to said first eccentric by means of an antifriction bearing.
An eccentric device for use in an assembly for driving a part with a reciprocating linear motion, said assembly including a pair of abutment members spaced a predetermined distance from one another and to the part to be driven, said eccentric device comprising:
- a first eccentric element disposable between the abutment members for rotation about an axis of rotation;
- a second eccentric element at least partially surrounding said first eccentric element and floatingly mounted thereto so that said second eccentric element is freely rotatable with respect to said first eccentric element;
- and
- means including an antifriction bearing for rotatably mounting said second eccentric element to said first eccentric element.
