oil temper
2.Abstract: In this paper the experimental research of hydra ulic oil used on a certain composite gearbox are carried on．The experimental fo rm ulas are drawn respectively between viscosity、density、specific heat and temper ature．The function of viscosity to temperature and pressure is deduced．The com parative analysis among the new oil、used oil and ordinary antifriction oil ind icates the performance of the specitic oil is excellent．These conclusions are b eneficial to the advanced analysis of the vehicle transmission system and formul ate the manual of relevant armored caterpillar.
