Spur Gear



Spur gears are one of the simplest and most widely used types of gears. Their general form is a cylinder or disk. The teeth project radially, and with these "straight-cut gears", the leading edges of the teeth are aligned parallel to the axis of rotation. These gears can only mesh correctly if they are fitted to a parallel axle. We manufacture durable and highly efficient Spur Gears up to 150 mm OD & 3.5 module in steel. These gears are essential components in Gearboxes used in Machine Tools, Material Handling Equipment, and Gear Pumps.

Characteristics of Spur Gears

Spur gears connect parallel shafts and feature involute teeth parallel to the shaft. These gears can have either internal or external teeth and are known for causing no external thrust between gears. Due to their straightforward design, spur gears are inexpensive to manufacture, providing a cost-effective yet satisfactory performance, especially when the shaft rotates in the same plane. The key features of spur gears include the dedendum, addendum, flank, and fillet.

The dedendum cylinder is a root from where teeth extend; it extends to the tip called the addendum circle. Gears for all applications can be produced to customers' design.

Types of Spur Gears

Explore the different types of spur gears that cater to various industrial needs:

External Spur Gears

External spur gears, with their conventional design, dominate the industrial landscape.

  • Automotive Transmissions: Widely used in automotive transmissions, external spur gears efficiently transmit power between shafts, playing a critical role in determining a vehicle's speed and torque.
  • Industrial Machinery: In industrial settings, such as conveyor systems, these spur gears transfer rotational motion between parallel shafts, making them ideal for heavy-duty machinery due to their robust design.

Internal Spur Gears

Internal spur gears find their niche in specialized applications.

  • Planetary Gear Systems: Internal spur gears find application in planetary gear systems, commonly used in automatic transmissions and robotics. Their compact design allows for a reduction in overall size while maintaining efficient power transmission.

Rack and Pinion Gears

Rack and Pinion gears are the go-to solutions for linear motion systems.

  • Steering Systems: Rack and pinion gears are a fundamental component in automotive steering systems. The rotational motion of the pinion gear is converted into linear motion along the rack, providing precise steering control.
  • CNC Machines and Robotics: In CNC machines and robotics, rack and pinion gears are frequently employed to achieve linear motion. This application is essential in various industries, ensuring accurate and controlled movement in machinery and robotic systems.
