Simulation Research on Gear of Helical Gear Pump

A group of suitable parameters are selected for simulation to obtain the toothed curve as shown in the figure.

Through simulation, we can see from Figure 9 that there are a few trapped areas between the top and the root engagement, so the spline curve of Figure 6 needs to be corrected.

A new set of spline curves can be obtained by adjusting a0, a1, R0 and R1 combined with the involute equation.Then carry out simulation until the problem of oil trap is solved.Figure 10 is the newly adjusted simulation result.

According to the final simulation curve, increase the helical angle beta, gear hobbing and grinding to get the physical objects of the drawing.
