Prevention relaxatoion of fix bolt of heavy equipment track chain

摘要

The information disclosed by the shoe and the track cross-links that make up the chain to the fixing bolt caterpillar-type tracks, When signed, the fixing bolt of the nut which increase the effective length of the fixing bolts which join the Sikkim reduced the cross-sectional area of the specific region in accordance with, since the internal elastic energy of the fixing bolt of the fixing bolt is increased due to excessive loads and shocks from the outside that it can be prevented from loosening, ; fixing bolt loosening prevention device for a heavy duty track chain according to an embodiment of the present invention, ; in the track shoe and the track chain link In the fixing bolt loosening prevention devices for heavy-duty track chain signed a, ; corresponding threaded portion of the fixing bolt and screw ball, fixing bolt and so as to increase the effective length of the punters one that extends to parts including a coupling groove formed in the nut, ; if to tighten the nut on the fixing bolt, an elastic energy to be valid response within the fixed bolts on the fixing bolt is increased by increasing the length of the engaging groove of the nut it is possible to prevent the loosening.
