WebIf the gears have the same hands, the sum of the helix angles should equal the angle between the shafts. The most common example of this are crossed helical gears with perpendicular (90°) shafts. Web23 mrt. 2024 · There are several types of gear but when we talk about spur gear of contact ratio less than 2 then theoretical length is assumed to be L (L = Contact Length). In case of helical gear contact length per tooth is L/cosα (α is helix angle). Because of helical action, total length of contact is always approximately L/cosαtimes contact ratio.
