Context 1

... extreme cutting edge of the tool forms one side of the worm wheel tooth while the second edge forms the other flank. An analysis of the contact pattern in a CAD environment can be carried out during transmission by assembling the worm and worm wheel models for the transmission stage ( Figure 4). As illustrated in Figure 4, the stationary coordinate systems S 1 (x 1 ,y 1 ,z 1 ) and S 2 (x 2 ,y 2 ,z 2 ) for worm and worm wheel were established, respectively. ...

Context 2

... analysis of the contact pattern in a CAD environment can be carried out during transmission by assembling the worm and worm wheel models for the transmission stage ( Figure 4). As illustrated in Figure 4, the stationary coordinate systems S 1 (x 1 ,y 1 ,z 1 ) and S 2 (x 2 ,y 2 ,z 2 ) for worm and worm wheel were established, respectively. The worm rotates around the z 1 axis by the angle ' 1 ϕ , opposite to the trigonometric direction. ...

Context 3

... the worm wheel model has to be rotated by the angle relative to the x 2 , so as to interfere into the worm tooth by the given value δ w ( Figure 5). By simulating gear rotation (Figure 4), the models rotate in fixed discrete steps, whose movements will be based on the gear ratio. For a given gear position, the intersection of the worm and worm wheel is determined ( Figure 6). ...

Context 4

... shifts of the worm in relation to the axis y 1 (Δa y ) and z 1 (Δa z ), as well as shift of the worm wheel in relation to the axis x 2 (Δa x ) were assumed for the gear. Angular deviations in relation to the worm axis were introduced, i.e., in relation to the axis x 1 -the deviation κ x , and in relation to the axis y 1 -the deviation κ y (Figure 4) are introduced. Also, possible translations and rotations of worm and worm wheel CAD models were introduced. ...
