No contact analysis can be performed for double helical gearings.
If this simplified method is not sufficiently accurate,
you can use the KISSsys system to perform a correct contact analysis for double helical gearings at any time by
entering each half of the gear into the KISSsys model as a separate item.
The double helical gearing is then handled as a normal helical toothed gear.
你不是这软件没这功能呀！该怎么办呢？
