Improving Reliability in Process of Repair of Rotor of Turbocharger of Internal Combustion Engine
Keywords
Abstract
Recommendations existing in different sources of information for the choice of methods of strengthening and reconditioning of worn machine parts have been analyzed in the article. To strengthen and restore the nominal size of rotors the method of gas-flame spraying of wear-resistant coatings has been chosen. The value of the economic reliability index of the rotors Kе equals to 17, 46. Higher rotor reliability is achieved at the expense of extra cost for rotor strengthening using powder ПГ-10Н01, and the price of Bн rotor reliability is 1800 UAH. Complex indicators of reliability of the reconditioned rotor are used for more complete reliability assessment: availability coefficient Kг equals to 0,999; coefficient of technical use Kтв equals to 0,998.
