1. The difference in transmission:
Whereas the gear is a meshing transmission, the spline serves as a connection.
2. Differences in appearance:
While gears are usually disc or shaft items, splines resemble a flower seen from a distance.
3. The difference between the modulus series:
There are many series of gear modules, and there are probably these modules:0.1mm,0.12mm,0.15mm,0.2mm,0.25mm,0.3mm,0.4mm,0.0.5mm,0.6mm,0.8mm,1mm,1.25mm,1.5mm,2mm,2.5mm,3mm,4mm,5mm6mm,8mm,10mm,12mm,14mm,16mm,20mm,25mm,32mm,40mm,50mm;The involute spline module is divided into two series of 15 types:0.25,0.5,0.75,1,1.25,1.5,1.75,2,2.5,3,4,5,6,8,10.
4. The difference between the pressure angle:
The involute spline pressure angle is 30°, 37.5°, 45°, while the gear pressure angle is usually 20°.
5. The difference between the requirements of the angle spacing between the two teeth:
The angle between the two teeth of the spline must satisfy the national standard; thus, one may choose the angle spacing between the two teeth of the gear at will depending on the real necessity.
6. The difference between the tooth length requirements:
The gear teeth should be short while the spline teeth should be long according to the tooth length specifications.
7. The difference between the minimum number of teeth:
The spline can be smaller than the minimum number of teeth of the gear (that is, the minimum number of teeth of the spline can be 10), while the gear has a minimum number of teeth, when the pressure angle is 20°, the minimum number of teeth is 14, and when the pressure angle is 25°, the minimum number of teeth is only 12.
The following is a firsthand knowledge of the two; if there is a mistake welcome your indication; if there is a gear processing requirement or another inquiry is welcome to consult.
