A spur gear is a type of cylindrical gear with straight teeth that are cut parallel to the axis of rotation. They are the simplest and most common type of element in mechanical drive systems. Spur gears transmit power and motion between two parallel shafts. In order to do so, both the pitch and the pressure angle of both gears must be the same. Spur gears can increase or decrease the speed and torque of the rotating shaft depending on the sizing and arrangement of the gears. The teeth of a spur gear are cut using a gear hobbing machine or a gear shaping machine. Spur gears can be produced from various materials, including steel, brass, bronze, or plastic, and depending on the application, they can be hardened based on the requirements for strength and durability.
Luoyang Deyu Machinery& Technology Co., Ltd mainly produces spur gears made of steel and brass, with modules from 1 to 50 and accuracy classes 6 to 9.
