Abstract

Basic theoretical background of obtaining the prolonged life of round gear hydraulic pumps during the repair is given. Physical-mechanical properties of coatings formed with the use of combined method are investigated. A mathematical model of relationship between the gaps in conjunctions with internal leakage in a hydraulic unit is obtained. The possibility of round pump repair with the use of combined method is confirmed.
