DEVICE FOR SETTING CENTRAL AXIS OF PERFORMANCE TESTER OF HYDRAULIC PUMP AND CENTRAL AXIS OF HYDRAULIC PUMP TO BE TESTED

摘要

PURPOSE: A device for setting central axis of performance tester of hydraulic pump and central axis of hydraulic pump to be tested is provided to easily and simultaneously control intervals of base bolts and the central axis. CONSTITUTION: Interval between blocks(110) is adjusted as a pair of plates(120) are moved right and left by a jack screw(230) penetrating centers of the plates and an upper part of a fixing plate(350). Distance of the blocks is adjusted by a pair of middle bases(200) are moved back and forth by a jack screw(230) having one side penetrating middles of a pair middle bases and the other side penetrating a central upper end of a fixing plate(260). Height of a pump(100) to be tested is adjusted as a pair of jack screw(250) having one sides penetrating one side of a pair of lower plates(210) and inserted to a long hole(211) and the other sides penetrating a central upper end of the fixing plate moves up and down a pair of upper plates(220) and a pair of lower plates(210). The pump is moved right and left as a base bed(300) is moved right and left by a jack screw(420) having one side penetrating a side of the base bed and the other side penetrating a central upper end of a sliding plate(400). The pump is moved back and forth as the middle bases are moved back and forth by a pair of jack screws(320) having one sides penetrating a fixing bracket(360) and the other sides penetrating a central front end of a fixing plate(310).
