IRASE

The aim of this publication is to show the process of computer aided designing of the spur gear pairs having normal and modified straight teeth. For designing, the determination of the geometrical parameters is needed. Computer programs have been developed with which gear pairs having normal and modified teeth, with any arbitrary parameters can be analysed, designed and modelled. With these programs gear pairs having concrete geometry have been designed and CAD models have also been drawn to have further meshing, geometrical and TCA (Tooth Contact Analysis).

“…For the modelling and contact analysis of the drive pair we draw the necessary coordinate system layout (Fig. 4) [1,3,4,7]. The profi le of the gear pair, i.e.…”

“…If the profi le shift coeffi cient is zero, then the reference line of the tool is the same as the datum line of the tool which touches the pitch circle of the gear. This wheel is called a spur gear having standard teeth [1,2,5,8,9].…”

Analysis of the Effect of the Addendum Modification Coefficient for Contact Surfaces of Spur Gear

The spur gear is widely used in many types of machines and appliances that is why the research of the connection analysis of them (Tooth Contact Analysis, TCA) is very important because of the development of these gears. The TCA analysis is a complex task because the mathematical description, the CAD modelling process, the overall designing process, the manufacturing process of the gears and the definition of the mechanical parameters have to be known. After the gear designing process the gear pairs have to be analysed by TCA method to determine the typical dimension of the mechanical parameters in case of given load. Knowing of the result we can reason for the appropriate gear geometry of the given construction and working conditions.

“…Five types of gear pairs have been designed by our developed computer software [1,2]. Knowing the necessary designing formulas and based on the input gear parameters (tooth numbers and module) the software could calculate the necessary gear parameters and determine the involute profi le curve.…”

The effect of the modification of the base profile angle of the x-zero gear drives for the TCA parameters

2019

IRASE

The aim of this research is the analysis of the effect of the modification of the base profile angles of x-zero gear drives for the TCA parameters. We analyze the normal stress, the normal deformation and the normal elastic strain on the connecting zone of the gear pairs. Based on the received results we create diagrams which show the fluctuation of the analyzed TCA parameters in the function of the changing of the selected parameter of the x-zero gear drives. After the analysis we determine the consequences and select the appropriate variant.
