What to settle before you ask for a quote
General guidance from SourceLoka for spur gear; it is not this company’s specification.
- Module, number of teeth, pressure angle and face width.
- Material and heat treatment, such as case hardening, and the hardness.
- Quality grade and the standard used, which sets tooth accuracy.
- Bore, keyway or spline, and the hub dimensions.
- Backlash allowance and the centre distance with the mating gear.
- Surface finish and the inspection report for critical gears.
What is a spur gear, and when should you choose another type?
The teeth are cut parallel to the shaft, so a pair of spur gears must mesh on parallel axes. They are easy to make and carry no axial thrust, but all the teeth in contact engage at once, which makes them noisier at high speeds than helical gears. The size of the teeth is set by the module, and a standard pressure angle makes gears from different makers interchangeable when other data match.
Spur Gear or helical gear? Spur gears are simpler and cheaper and create no axial load, but they are noisier at speed. Helical gears run more smoothly and carry more load, but need bearings to take the axial thrust.
It is the ratio of the pitch diameter to the number of teeth, in millimetres, and it fixes the size of the teeth. Two gears must have the same module to mesh.
It is the small clearance between meshing teeth. Some backlash is needed for lubrication and thermal expansion, but too much causes noise and positioning error.
