MODERNIZATION OF FANS OF DIESEL LOCOMOTIVES COOLING SYSTEM

Abstract

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The article introduces a technical solution for modernization of a fan of cooling system of locomotive diesels. The new patented design eliminates imbalance of the fan wheel and increases its reliability during operation. The authors set out operation principle of the device and method to determine a number of rolling elements that perform a function of imbalance loads. The proposed development is the result of cooperation between research departments of MIIT and Yelets University. Keywords: locomotive, diesel, cooling system, fan wheel, imbalance, modernization.
