1) Features of Spur Gears
The feature a simple construction of straight, parallel teeth that are positioned around the circumference of a
cylinder body with a central bore that fits over a shaft.
Spur gears are classified as cylindrical gears. Since the tooth surfaces of the gears are parallel to the axes
of the mounted shafts, no thrust is generated in the axial direction.
2) Manufacturing of Spur Gears
The spur gear gear is machined with a hub that thickens the gear body around the bore without changing the gear surface.
The central hole can also be drilled so that the spur gear fits onto a spline or a keyed shaft.
