ICE CRANKSHAFT FATIGUE TORSION TEST BENCH

摘要

FIELD: engines and pumps.SUBSTANCE: claimed device comprises servo hydraulic loading device (SHL), crankshaft element (1) with one end rigidly coupled via PTO flange to vertical fixed prop (7). Roller (2) fitted with interference on the shaft free end can roll free over the thrust plate (5) rigidly fixed to SHL table. Thrust plate surface (5) in contact with the roller (2) follows the thrust surface thereof. Lever (4) is secured to roller (2). Offset load from SHL piston is carried via spherical thrust (6) coupled therewith to said lever (4) to make roller (5) swing about the axis aligned with that of the crankshaft (1) to transmit the torque thereto.EFFECT: setting of arbitrary loading law.1 dwg
