Product features
Helical 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%.

Application of steel spur gears
Spur gears are widely used in construction equipment, outboard motors, machine tools, lawn and garden equipment, marine hoists, multi-spindle drives, snow throwers, turbine drives, pumps, centrifuges and other power transmission equipment.
Gears are a crucial part of many motors and machines. Gears help increase torque output by providing gear reduction and they adjust the direction of rotation like the shaft to the rear wheels of automotive vehicles. Here are some basic types of gears and how they are different from each other.
Neway offers various series of plastic gears and gear parts such as plastic worm gear, plastic spur gear, plastic helical gear, plastic pinion gear, plastic bevel gear, plastic gear rack. If you want to test it easily, rapid prototype can also provide to save cost and time(3-7days).
