Straight Bevel Gear Machining Service

planing

Planing provides flexible profile cutting for prototypes and small batches.Fast setup, efficient for non-standard features before heat treatment.

Grinding

Ginding delivers tight tolerances and superior surface finish on critical fits.Supports ID/OD, gear/spline, thread, jig, and surface grinding as needed.

Lapping

Lapping fine-tunes bevel gear contact pattern to improve smoothness and load distribution.
It helps reduce local stress and supports more consistent meshing in real assemblies.

milling

Milling delivers flexible, CNC-controlled cutting for prototypes and small batches.
Ideal for thin-plate parts and non-standard bevel gears where tooling needs to stay agile.

forging

Forging forms dense blanks with improved grain flow for high-load bevel gear applications.
Best for robust gear blanks that require strength before precision machining.

Powder metallurgy

Powder Metallurgy makes near-net-shape gears with consistent repeatability at scale.
Great for small-module or complex geometries, cutting material waste and machining time.

Quality Control

Prior to every shipment, we conduct the following tests and provide complete quality reports for these gears.:
1. Bubble drawing
2. Dimension measurement report
3. Material certification report
4. Heat treatment testing report
5. Accuracy measurement report

Packaging

Step 1 – Anti-rust: We wrap each gear with VCI anti-corrosion paper / bag to protect it from rust during shipping.
Step 2 – Inner protection: The wrapped parts are placed properly to avoid scratches and impact.
Step 3 – Carton packing: Then we pack them into strong export cartons (logo printing is available).
Step 4 – Crate & pallet: Cartons are loaded into a reinforced plywood crate with partitions, and fixed on a pallet.
Step 5 – Secure & label: The crate is sealed, strapped, and labeled, ready for sea/air shipment.

We can also provide custom printed color boxes and logo customization (carton, color box, crate marking, labels).
Note: Please ensure the logo/design is authorized by you; if it involves any third-party brand, we will need written authorization to avoid IP risks.

FAQ

Do you make straight bevel gears for marine outboard engine?

Yes. We manufacture straight bevel gears for marine outboard engine when the design favors simpler bevel geometry. Provide speed, torque, shaft angle, and lubrication notes so we can propose heat treatment and inspection aligned to marine duty.

Can you quote from a worn sample gear?

Yes. A sample helps, but we prefer receiving the mating gear or its drawing as well. That improves confidence in mesh fit and backlash intent, reducing the risk of noise or early wear after installation in the lower unit.

What RFQ data is essential for marine straight bevel gears?

Provide ratio, shaft angle, tooth data, face width, bore interface, material, heat treatment targets, and quantity. Also include corrosion exposure assumptions, sealing approach, and oil type, since marine environment risks often drive packaging and inspection choices.

Do you support corrosion protection and packaging?

We can recommend surface protection and packaging based on storage duration and humidity. Confirm whether the gear runs in a sealed oil bath and how water ingress is prevented. That information helps us propose realistic measures without over-promising.

What inspection report can you provide?

We can provide dimension checks, runout results, and tooth measurement evidence as requested, plus hardness records when heat treated. If you need additional checks or a report format for incoming QC, list it in your RFQ.

What commonly causes failures in outboard right-angle drives?

Water ingress, incorrect lubrication, contamination, or setup variation are common. Share seal details, oil grade, operating temperature, and any failure photos. We can suggest practical backlash targets and inspection focus to reduce noise and wear.
