Tooth contact analysis of x-zero helical gears by the modification of the tooth trace

Abstract

The helical gear pairs are widely used in different mechanical constructs. The main advantage is the good efficiency and the low noise during the connection.We have worked out a computer software with which the designing process of the helical gears could be eased. Based on the calculated gear parameters the CAD models of the elements could be prepared. Knowing of the geometries the assembly could be created based on the fixed freedom degrees and the elementary centre distance. We have designed five types of gear pairs. The differences are only the different tooth traces. All of other parameters have not been modified. We have done TCA which is meant we have analyzed the effect of the modified parameter for the normal stress, normal deformation and the normal elastic strain on the contact zone. Based on the results we have prepared diagrams for the analysis of the correlations between the changing parameters.

Tooth contact analysis of the effect of the addendum modification coefficient of helical gears having modified teeth

“…Based on the references' recommendations [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] we have created a computer software [20] with which the necessary geometric parameters could be determined (Table 1). This program can calculate the profile curves of the elements as well [20]. After that the CAD models could be built up by SolidWorks software (Fig.…”

“…The aim of the TCA is the determination and analysis of the mechanical parameters on the contact zone by different loads [6][7][8][9][10][11][12][13]20]. Based on this the stresses and deformations could be estimated forward before the real industry circumstances.…”

“…The main property of the helical gear having modified teeth is the sum of the two addendum modification coefficients are zero [1,3,5,6,7]:…”

“…In spite of this the tooth connection is happened on the pitch circle diameter (Figure 2) [1,3,5,6,7]. Knowing of the reference's recommendations [3][4][5][6][7] a Matlab computer software was developed to the easement of the designing process.…”
