Abstract
853,267. Endurance testing machines. AVERYS Ltd., [formerly AVERY Ltd., W. & T.] (Schenck Maschinenfabrik G.m.b.H., C.). Feb. 23, 1957, No. 6162/57. Class 106 (2). [Also in Group XXIV] In a testing machine which applies repetitive stresses to a workpiece through a connecting rod 5 and a variable-throw crank the pin 4 of which is mounted on an eccentric 3 adjustable in a casing 2, 2e rotated by a pulley 1 about an axis 2c, the mutually engaging surfaces of the eccentric 3 and casing 2e are arranged to produce sufficient friction to balance the maximum force transmitted to the workpiece. This condition obtains if the radius of the eccentric 3 is equal to or greater than the maximum eccentricity multiplied by the inverse of the coefficient of friction between the surfaces. In a modification, Fig. 6, the required friction is obtained by a clamp ring 15 pressed upon the eccentric 3 by springs 17. The eccentric 3 and casing 2e may have engaging conical surfaces. The crank throw may be adjusted during the operation of the machine by a motor 11 within the rotating casing 2 turning the eccentric 3 through gearing 12, 13.
