As shown in the figure, the three-dimensional cloud diagram of contact stress of No. 0 unmodified, No. 1 optimization scheme

Figure 1 shows the influence curve of helix angle on the time-varying meshing force of the helical gear pair at

As shown in the figure, the tooth surface load distribution of No. 0 unmodified, No. 1 optimization scheme and No.

Under the ideal oil lubricated meshing condition, the big and small gear teeth will be completely separated by the oil

(1) Gear profile optimization modification+tooth direction drum modification Figures 1, 2, 3, 4 and 5 respectively show the composite modification

(1) Influence of pressure angle on transmission error of helical gears Figure 1 shows the relationship curve between pressure angle

(1) Optimal modification of linear addendum with long tooth profile Figures 1, 2 and 3 respectively show the simultaneous long

(1) Selection of long and short modification methods Long modification refers to the repair and removal of the part from

For helical gear pair transmission, the number of rotation cycles of the pinion is more than that of the big

As shown in Figure 1 (a), under ideal or no-load conditions, the helical gear pair can mesh smoothly and bear

In order to solve the problem of serious squealing and knocking noise of helical gears in the reduction gearbox, improve

Knocking mainly occurs on the helical gear box components such as meshing no-load helical gear, synchronizer and sliding sleeve. Due
