DEVICE FOR TESTING DURABILITY OF RUBBER ELASTIC BODY AND DURABILITY TEST METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To enhance repeatability of damaged phenomenon caused by eating of worms in a rubber crawler and then to increase reliability in durability evaluation of the rubber durability on the damage phenomenon caused by eating of the worms.;SOLUTION: A device for testing durability of a rubber elastic body includes stepping means 3 which can reciprocate back and forth by stepping on a stone h bitten in between a piece G to be tested. The stepping means 3 includes an oscillation body 4 which is supported by a support shaft 10 capable of moving back and forth so as to be able to oscillate back and forth. The oscillation body 4 includes a trapezoidal shaped main part 13 having a bottom surface 13A forming a stepping surface 4S, a front surface 13F extending frontward from the bottom surface 13A while keeping upward inclination, and a back surface 13R extending backward while keeping the upward inclination.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
