Description
Double helical gears (sometimes known as Herringbone Gears) give the same advantages and smoothness as single helical gears, but with the added value of much greater strength in the contact of the teeth and no sideways force or end load on the mounting shafts. They can directly replace spur gears without re-designing the mounting bearings, except in the case of more power being transmitted through the combination. Double helical gears are more difficult to produce due to their more complicated shape and, hence, more expensive than spur gears.
Double helical gears are used in many applications such as cranes, fluid pumps, and power transmission to the propulsion screws in military ships for a quieter and less vibration operation.

1. Quotation: Under normal circumstances, as long as we confirm your drawings (IGS, STEP, STL, PDF, DWG, etc.) and information (materials, tolerances, surface treatment and quantity), your inquiry can be within 8 hours at the fastest Offer.
2. NDA signing: cooperate with us, your business and funds will be safe. Therefore, before cooperation, NDA is effective for you.
3. Sample test: In order to ensure the smooth progress of mass production, samples need to be tested before production and given to you for confirmation. If the product does not require molds, samples can be made within 15 days, the fastest is three days. It usually takes 20-30 days to make molds and samp if molds are needles.
4. Mass production: We can provide you with the progress of parts manufacturing through pictures and videos after we give you confirmation and approval for mass production.
5. Assembly and packaging: If you need, we can help you assemble the entire product. Including internal and external packaging and label Logo.
