Szukana fraza: [Abstrakt = "The aim of this article is to analyze the influence of the more important factors deter\-mining the use of electrical energy and ammonia in the process of gearwheels nitriding used in truck engines. The following analysis is based on experimental research as well as the currently existing literature data. While performing the processes, the amount \(the weight\) of gearwheels, the setting of the furnace in a retort as well as the number of fan rotations were changed. The processes were carried out in a vertical furnace in the Institute of Machines and Motor Vehicles at Poznan University of Technology. The results show that the electrical energy usage increases with the rise in the number of gearwheels used in the heating of the batch \(and the furnace\). In the nitriding process \(after the heating\) the consumption takes the fixed value. The results also indicate that the increase in the number of gearwheels influences the ammonia usage in the process of heating as well as annealing \(during nitriding\). Little influence of the gearwheels orientation on the use of two analyzed factors as well as the influence of the number of fan rotations on the ammonia usage have been indicated. The increase in the number of fan rotations significantly lowers the usage of the gas."]
