This Spur Gear is a type of cylindrical gear which is excellently made to operate on parallel shafts to transmit both motion and power. It is enclosed around a central axle and comprises of one or more screwed thread performing as their teeth. Spur Gear is quite efficient as compared to helical gear and highly appreciated due to their unmatched attributes like high power transmission efficiency, simple and easy to design and power transmission efficiency in case of spur gear driving system will be quite good.
