Product features

Big spur gears are round metal disks with teeth cut around the circumference. In order for the gear to qualify as a gear, the tooth must be cut so that they run perpendicular to the gear’s face. Helical gears are the simplest design of gear produced. They are usually used for the transmission of rotary force. For example, if two shafts are parallel to one another, and one is spinning, a helical gear can help to transfer that force onto the other shaft. Helical gears usually have an operating efficiency of 98% to 99%.
