Custom Injection Molding Plastic Gears from China's Suppliers and Factory - Precision Micro to Planetary Gears

Spur gears are the most common gear type. They feature straight teeth parallel to the shaft axis and are ideal for simple speed reduction and torque transfer applications.

Helical gears use angled teeth for smoother engagement, reduced noise, and improved load capacity compared with spur gears.

Worm gear systems consist of a worm shaft and worm wheel, allowing large speed reduction ratios in compact spaces. They are commonly used in lifting devices, conveyors, and seat adjustment systems.

Bevel gears transmit motion between intersecting shafts, usually at 90 degrees. They are often used to change rotational direction.

Planetary gear systems combine a sun gear, planet gears, and ring gear to deliver high torque in a compact design.

Internal gears have teeth on the inside diameter and are commonly used in planetary gear assemblies.

Custom molded compound gears combine multiple gears, pulleys, or cams into one component, reducing assembly time and lowering production costs.

The most distinctive feature of crown gears (i.e., face gears) is their vertical tooth structure. Their teeth stand upright directly on the end face of the disk, rather than being distributed in a tapered shape with an incline.

The biggest advantage of double helical gears (herringbone gears) lies in their self-balancing. They solve the axial load problem through symmetrical design.
