Improvement in Load Capacity of Crossed Helical Gears - January/February 1987
The article "Improvement in Load Capacity of Crossed Helical Gears" appeared in the January/February 1987 issue of Gear Technology.
Crossed helical gear sets are used to transmit power and motion between non-intersecting and non-parallel axes. Both of the gears that mesh with each other are involute helical gears, and a point contact is made between them. They can stand a small change in the center distance and the shaft angle without any impairment in the accuracy of transmitting motion.
