LINK-GEAR MECHANISM OF A DYNAMIC LEAF SPRING TESTING MACHINE

Click to enlargeClick to enlarge Description

Crank 1 turns about fixed axis and is connected by turning pair B to slider 11 which moves along slot a of slotted link 2. Slotted link 2 rolls along roller 3 which rotates about fixed axis C. Link 2 is connected by turning pair D to link 4 which slides in fixed guide p. Link 4 actuates plunger 5. When crank 1 rotates about axis A, link 2, bearing on roller 3, applies an alternating load through link 4 and plunger 5 on leaf spring 6 being tested. Roller 3 can be adjusted in the horizontal direction, varying the distance A͞C and, thereby, the upward stroke of plunger 5. The machine can also be employed for the static testing of leaf springs. In this case the machine is powered through belt drive 7, worm gearing 8, screw 9 and plunger 10.
