The article deals with the contact analysis of selected toothed gears of the two-stage front gearbox. They are extensively used throughout the machine industry, but also in other mechanical devices where input parameters change to the required working values. The aim of this work is to point out the effect of deformations of the individual gear components on the correctness of the toothed engagement. The work deals with the contact analysis of selected gears of the two-stage front gearbox. The subject of the study is to determine the resulting coefficient of unevenness of the tooth load over the width of the contact for deformation of individual parts of the gearbox using the KISSsoft computerized software. The pc software KISSsoft has several ways to define a coefficient KHβ. The method using the ISO 6336 standard was used in this case. Due to load, the teeth of the wheels resiliently deform. This deformation has an effect in an enlargement of the coefficient of the toothed contact. The result is the processing of data and their evaluation for individual types of deformations of the parts of the gearbox unit and the subsequent evaluation of the overall impact on the life of the gearbox.
