Spur Gears
Straight teeth parallel to the axis for efficient power transmission, simple geometry and a broad range of speeds and loads.
Custom Cylindrical Gear Manufacturer
Belon Gear manufactures custom cylindrical gears and gear sets for industrial transmissions. Select spur, helical, internal or planetary gearing, then define the module or diametral pitch, tooth count, helix angle, material, heat treatment, accuracy, backlash and inspection requirements for the application.

Use the tooth form, shaft arrangement and gearbox architecture to choose the correct family. Each child category below carries the detailed commercial intent, while this page remains the parent hub for custom cylindrical gears.
Straight teeth parallel to the axis for efficient power transmission, simple geometry and a broad range of speeds and loads.
Angled teeth provide gradual engagement for smoother running, reduced noise and higher load sharing than comparable spur gears.
Teeth formed on the inside diameter of a ring, commonly used where compact packaging and planetary engagement are required.
Matched sun, planet and ring gear elements for compact, coaxial transmissions with high torque density and multiple ratio options.
The correct gear family depends on shaft position, noise, speed, load, packaging, ratio and assembly requirements. Final geometry and rating should be checked using the complete operating data.
| Gear type | Tooth and shaft arrangement | Typical selection reason | Design note | Category |
|---|---|---|---|---|
| Spur gear | Straight teeth; parallel shafts | Efficient, robust and straightforward power transmission | Check mesh frequency, noise, backlash and tooth width against speed and load. | Spur gears |
| Helical gear | Angled teeth; usually parallel shafts | Smoother engagement, reduced noise and increased overlap | Specify helix angle and hand; axial thrust must be supported by the bearing arrangement. | Helical gears |
| Internal gear | Internal teeth meshing with an external pinion | Compact layouts, ring gears and planetary systems | Confirm the mating pinion, tooth-number combination, interference limits and inspection method. | Internal gears |
| Planet gear set | Sun, planet and internal ring gear system | Coaxial input/output, compact ratio and high torque density | Treat the sun, planets, ring and carrier geometry as one matched transmission system. | Planet gear sets |

Custom cylindrical gears support parallel-axis, planetary and integrated gear-shaft transmissions across a wide range of industrial equipment.
Belon Gear offers spur, helical and internal gears as well as planetary gear sets. Products may be supplied as individual gears, matched sets, ring gears or integrated gear-shaft components according to the drawing.
Spur gears use straight teeth parallel to the axis. Helical gears use angled teeth that engage progressively, which generally supports smoother and quieter operation but also introduces axial thrust that must be considered in the bearing design.
Internal gears are useful where an external pinion must mesh inside a ring. A planetary set is considered when the transmission needs coaxial input and output, compact packaging, load sharing or a specific multi-member ratio arrangement.
Send the drawing or 3D model when available, together with module or DP, tooth count, pressure angle, helix data, material, heat treatment, accuracy, backlash, speed, torque, duty cycle, quantity and inspection requirements.
Yes, many designs use an integral spur or helical pinion shaft. The shaft journals, shoulders, splines, keyways, bearing fits and gear teeth should be reviewed together so machining, heat treatment and inspection datums remain consistent.
Send the drawing, operating data and quantity so the appropriate gear type, material, heat treatment and manufacturing route can be reviewed.
