Abstract
The topic of this publication is the reconstruction and measuring process of a used straight spur gear. The tooth number, the tip circle diameter and the tooth length have to be measured for the reconstruction. Based on these parameters the type of the straight spur gear has to be determined. For the designing of the gear a new computer program is created. Based on the calculated parameters the CAD model of the gear could be designed. The profile of the real spur gear is measured by a microscope having computer controlled. The real and the theoretical involute profile curve will be analysed.

Summary
1. Introduction The aim of the publication is the reconstruction and measuring process of a straight spur gear. The module is the basic parameter of a spur gear [2, 4, 5, 6, 7]. The main parameters of a connecting gear pairs could be seen on Figure 1 and Table 1.
