Manufacturing capability
Technical Overview & Engineering Capability for custom straight bevel gears.
Custom straight bevel gears use straight tooth lines formed along a conical pitch surface. They normally transmit motion between intersecting shafts, commonly at a right angle, while different tooth counts provide the required speed ratio. ZhongYi reviews straight bevel gear and pinion requirements from buyer drawings, samples, and assembly information. The review covers ratio, shaft angle, module or diametral pitch, pressure angle, tooth counts, pitch-cone geometry, face width, mounting distance, bore or integral shaft features, material, heat treatment, backlash, lubrication, and inspection criteria. Straight bevel gears must be evaluated as a mating pair because tooth geometry, cone angles, installation position, housing alignment, and bearing support affect contact. This page is intentionally separated from Spiral Bevel Gears so buyers can specify the correct tooth form without mixing two different manufacturing and assembly requirements.

Product types & variants
Straight Bevel Gears types and manufacturing paths.
The final product form is confirmed from the buyer drawing, mating component, assembly layout, operating conditions, and inspection requirements.
Straight bevel pinion shafts
Integral pinion-and-shaft components that combine straight bevel teeth with bearing journals, shoulders, splines, threads, or keyways.
Finished-bore straight bevel gears
Drawing-defined gears with completed bores, keyways, splines, hubs, flanges, and datum surfaces for the buyer assembly.
Replacement straight bevel sets
Matched replacement pairs reviewed with the housing, bearings, mounting distances, operating conditions, and both original members where available.
Selection & Metallurgy guidance
How to specify the correct straight bevel gears configuration.
Start with the complete shaft relationship rather than the outside diameter of one worn gear. Confirm the ratio, shaft angle, tooth counts, module or DP, pressure angle, pitch-cone data, mounting distances, and direction of rotation for both members. The RFQ should also define bore or shaft interfaces, bearing arrangement, housing datums, backlash, material, heat treatment, and required tooth finish. Operating torque, speed, duty cycle, shock load, lubrication, temperature, and contamination help determine the manufacturing and inspection route. For replacement work, provide both mating gears, the installed orientation, housing center geometry, and any original drawing or service information. A straight bevel gear should not be substituted with a spiral bevel gear merely because the outside dimensions appear similar.
Material & Heat Treatment Options
- Carbon steel for general industrial straight bevel gears
- Alloy steel when the drawing specifies heat treatment or higher wear resistance
- Stainless steel for selected corrosion-conscious operating environments
- Engineering plastic or buyer-specified materials only after application review
Engineering Selection Factors
- Ratio, shaft angle, tooth counts, and direction of rotation
- Module or DP, pressure angle, cone geometry, and face width
- Mounting distance, bearing support, housing alignment, and backlash
- Bore, keyway, spline, hub, integral pinion shaft, and datum scheme
- Material, heat treatment, tooth finishing, lubrication, load, and speed
Quality Control & Inspection Matrix
Engineering Evidence & 100% Inspection for Straight Bevel Gears.
Overseas procurement teams require verifiable technical data, not unsupported claims. Every production batch at ZhongYi is inspected against approved CAD blueprints and international standards (DIN, AGMA, ISO).
Component-Specific Quality Focus:
Straight bevel gear quality depends on pair control and installation data. ZhongYi can review the drawing revision, mating tooth data, blank and bore datums, shaft features, material, heat treatment, mounting distance, backlash, and inspection requirements before quotation. Depending on the approved technical file, checks may cover blank dimensions, bore and face runout, tooth thickness, pitch-related characteristics, hardness, mounting features, and mating or contact verification. The pair should remain identified through manufacturing and packing when supplied together. Housing alignment, bearing rigidity, final assembly adjustment, torque capacity, noise, and service life are not assumed from a category name and must be confirmed by the buyer design or agreed validation plan.

Technical FAQ
Common technical and purchasing questions for Straight Bevel Gears.
These answers support early engineering and procurement review. Final dimensions, materials, tolerances, and process requirements are confirmed against the approved drawing file.
What information is needed to quote straight bevel gears? โผ
Provide drawings for both members, tooth counts, ratio, shaft angle, module or DP, pressure angle, cone and mounting data, face width, bore or shaft features, material, heat treatment, backlash, quantity, operating conditions, and required inspection records.
Can one damaged straight bevel gear be replaced without its mate? โผ
A single member can be reviewed, but wear and prior assembly errors may hide the intended geometry. Supplying both gears, housing dimensions, bearing arrangement, installed orientation, and original drawings gives a safer basis for a matched replacement.
What is the difference between straight and spiral bevel gears? โผ
Straight bevel gears have straight tooth lines along the cone. Spiral bevel gears have curved teeth with defined right- and left-hand members. They require different tooth geometry, process planning, thrust review, and pair control, so the two pages and images are kept separate.
