Types of Gear Materials

As most people know, gearboxes are designed to increase the output torque or speed of a motor. The shaft of the motor attaches to the gearbox and creates a specific output speed and torque that is pre-determined by the gear ratio.

An angle gear box is simply a gearbox created on an angle, to help save space and achieve a variety of speed and torque reduction processes that are impossible with other gear shapes.

Generally, an angle gear box can be made from a variety of materials. Most gearboxes uses steel-based metals as their main material. Boxes made from aluminum, brass, iron, and stainless steel are all common materials for gear boxes. Certain shapes of gears can be made from less durable materials, including the spur gear. Nylon and polycarbonate are two popular plastics used to create spur gears. The type of material used in the gearbox can actually change the performance of the gearbox. Stronger materials can provide a larger reduction in torque, and can resist the power of stronger motors. The lighter materials are best suited to motors with less power. A motor that is too strong for the angle gearbox will destroy the gearbox and could also damage the motor itself.

How the teeth of the box are shaped also affect the performance of the box. Straight teeth are best suited to low-speed applications. Helical teeth are best suited to high-speed applications because of their increased strength. Usually, helical teeth are also more efficient at torque reduction.
