抄録

With the purpose of improving performance of lubricant at low temperature and unifying lubricants to be used, we made new synthetic lubricant for watch mechamism. In this paper, we selected ester oil among several kinds of synthetic oils. We found that ester, as base oil, was superior in performance at low temperature and cahracteristic of evaporation rate, which has three ester groups in one molecule synthesized with tri-methylopropane and alkyl acid. We defined that the viscosity of the above mentioned lubricant should be 15cSt to 1000cSt at its used temperature range(-30 to 80°C). We found by evaluating performance of watches that the consumption electric current and the voltage to start moving with the lubricant at the used temperature are both almost same as with the existing lubricants. We also found by evaluating durability by accelerating test that the performance of the train wheel movement for twenty years is almost same. From the above we can obtain the new lubricant for watches which is superior in performance at low temperature and which we can apply for every part in watches.
