Crown Bevel Gears for Truck Gearbox

What is the crown gear’s basic definition?

A crown gear is a bevel-gear form with a 90-degree pitch cone angle and teeth projecting at right angles to the face, often used in 90-degree crown-and-pinion transmissions.

What data is needed to quote truck-duty crown gears?

Mating pinion data, speed/torque (including peaks), duty cycle, lubrication method, mounting constraints, and quantity. If impact or reversing loads exist, note them.

Do you support prototypes and low-volume orders before mass production?

Yes. We support prototyping and small-batch runs to validate fit, meshing, and assembly performance before scaling up. MOQ depends on gear design and tooling needs, and we will suggest a cost-effective trial quantity.

Can you quote from a sample part?

Yes. A sample is workable, but mating pinion information improves accuracy. Photos of the assembly and mounting datums also help reduce fit issues.

What inspection reports and certificates can you provide?

Upon request, we can provide a Certificate of Conformance, material mill certificates, dimensional inspection reports, and other verification documents based on your acceptance requirements and order type.

What is the lead time for custom bevel gears?

Typical lead time depends on design complexity, tooling, and heat-treatment schedule. As a reference, prototypes are often 25–40 days, and production orders are commonly 20–40 days. We will confirm a schedule after drawing review.

How do you handle packaging, shipping, and export documents?

We use export-ready packaging with rust protection and secure cartons or wooden cases as needed. We can ship by air, courier, or sea, and provide standard export documents such as packing list, commercial invoice, and other paperwork required by your import process.
