Operationally normal wears of transmissions, teeth of which consist of legs &load, are uneven during the length of the profiles, which inevitably bads to pitting & to increase of the dynamics. Vibradiagnostical method, laser radius gauge & manual correcting grinding mashine allows to remove pitting & liquidate increasing dynamics 3-5 times during the exploitation of the transmission. Using of the outpole transmissions allows to reduce the probability of pitting & of the dynamic increase.
