Rubber sheet fatigue testing machine with circulating stretching mechanism

Abstract

The utility model relates to material mechanics performance test equipment technical field discloses a rubber board fatigue test bench with cyclic tensile mechanism, including work table, first adjusting support, second adjusting support, cyclic tensile subassembly and guide mechanism. Cyclic tensile subassembly includes motor, synchronous belt, gyro wheel, linkage connecting rod, crank and first sliding block, and the motor rotates gyro wheel through synchronous belt drive, and gyro wheel drives linkage connecting rod, and linkage connecting rod drives first sliding block to slide in the guide long groove of crank, and the reciprocating linear motion of crank is stably converted to rotary motion, and then drives first adjusting support to realize cyclic tensile. Guide mechanism guides second adjusting support synchronous movement through the cooperation of track and sliding block. The utility model solves the problem of the prior art transmission instability, has compact structure, transmission stable and reliable, accurate guide, stretching process is stable, effectively improves the beneficial effect of test result accuracy.
