1. The spur gear is a non-complex kind of gear model specifically applied to conduction of rotary motion between parallel shafts.  The spur gear is stands the first for the related performance operations except high speeds, loads, and ratios direct towards other options.

2. A single spur gear is usually having a ratio range of between 1:1 and 1:6 with a pitch line of speed up to 25 m/s.   The spur gear operates at an efficiency of 98-99%.  The pinion is designed from a harder material than the wheel.  A

3. The minimum number of teeth on a gear with a normal pressure angle of 20 degrees is 18.

4. These singel stage spur gears also come with intermediate.
