1) Description of Spur Gear
The spur gear is the most basic type of cylindrical gear.
Its tooth line is parallel to the gear axis, and its tooth profile is a straight involute curve.
2) Feature of Spur Gear
a)The tooth profile is of a simple straight-line involute shape.
b)During meshing, the entire tooth width comes into contact simultaneously.
c)Can only be used for transmission between parallel shafts.
3) Advantage of Spur Gear
a)The structure is the simplest and the manufacturing cost is the lowest.
b)The transmission efficiency is as high as 98-99%
c)No axial force is generated, and the bearing design is simple.
d)Easy to process and maintain.
