Manufacturing capability
Technical Overview & Engineering Capability for custom spur gears.
Custom spur gears are a practical choice for transmitting motion between parallel shafts because their straight involute teeth are straightforward to specify, inspect, and integrate into machinery. ZhongYi reviews spur gear requirements from buyer drawings, samples, or confirmed technical data. The review covers module or diametral pitch, pressure angle, number of teeth, face width, bore, hub, keyway, material, heat treatment, and the mating gear. This drawing-led process is suitable for new OEM components as well as replacement gears that must fit an existing shaft and housing.

Product types & variants
Spur Gears types and manufacturing paths.
The final product form is confirmed from the buyer drawing, mating component, assembly layout, operating conditions, and inspection requirements.
Ground or hardened spur gears
Used when the project calls for tighter tooth finish, wear resistance, or more controlled meshing after heat treatment.
Hubless and shaft pinion designs
Compact forms that place the gear directly on a shaft or remove the conventional hub to suit restricted assembly space.
Stainless steel and plastic spur gears
Material-led options for corrosion exposure, washdown-conscious machinery, low mass, or quieter light-duty movement.
Selection & Metallurgy guidance
How to specify the correct spur gears configuration.
Start with the mating geometry rather than the outside diameter alone. Module or DP, pressure angle, tooth count, center distance, and profile data must agree with the mating gear. Then confirm how the gear locates on the shaft: finished bore, spline, keyway, interference fit, locking feature, or integral shaft. For replacement work, provide the worn part together with shaft and housing information whenever possible. Load direction, peak torque, speed, lubrication, temperature, contamination, and expected service life help determine whether a cut, hardened, or ground tooth finish is appropriate.
Material & Heat Treatment Options
- Carbon steel for general machinery components
- Alloy steel where the drawing requires heat treatment or higher wear resistance
- Stainless steel for corrosion-conscious operating environments
- Engineering plastic when low mass, low noise, or lubrication limits are important
Engineering Selection Factors
- Module or diametral pitch and pressure angle
- Tooth count, ratio, center distance, and mating gear
- Bore, keyway, hub style, face width, and runout datum
- Load, speed, duty cycle, lubrication, and operating noise
- Heat treatment, tooth finishing, tolerance, and inspection requirements
Quality Control & Inspection Matrix
Engineering Evidence & 100% Inspection for Spur 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:
A reliable spur gear order depends on controlled technical information. ZhongYi can review drawing revision, material grade, heat-treatment notes, datum references, bore and keyway dimensions, tooth geometry, and inspection requirements before quotation. During manufacturing, inspection points should follow the approved drawing and may include blank dimensions, bore and face runout, tooth thickness, pitch-related checks, hardness, and mating or contact verification when specified. Critical tolerances and the required inspection record must be agreed before production; unsupported accuracy grades or performance claims are not assumed.

Technical FAQ
Common technical and purchasing questions for Spur 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 custom spur gears? โผ
Provide a 2D or 3D drawing where available, or a sample with module or DP, pressure angle, tooth count, face width, bore, hub, keyway, material, heat treatment, quantity, and operating conditions. The mating gear and center distance are especially useful for replacement projects.
Should I choose cut, hardened, or ground spur gear teeth? โผ
The decision depends on load, speed, duty cycle, wear target, noise expectation, and the accuracy required by the assembly. Heat treatment can change dimensions, so the drawing should identify which surfaces require finishing after treatment.
Can a spur gear be produced from a worn sample? โผ
A sample can support initial review, but wear may hide the original tooth thickness or profile. Supplying mating-part data, shaft dimensions, center distance, and any historical drawing reduces the risk of reproducing wear instead of the intended geometry.
