What Are Spur Gears And Their Industrial Applications?

Spur Gear is an elementary type of gear that is used in many industries to transfer power and control speed and torque. Because of its durability, less cost, and reliability, it is used to fulfill different industrial purposes. 

Let us know in brief about spur gear, its advantages, and in which types of industries are using Spur Gears.

What Are Spur Gears?

The spur gear is the most commonly used gear type and is also known as the simplest gear because of its design. These gears have teeth on the surface of the circumference body or disk. Teeth are parallel to each other, and it is aligned straight to the rotation axis. When the spur gear is exposed to the shaft, then no axial thrust is produced. 

It is mostly used for moderate speed, and it may be noisy when it is used for high-speed operations. There are two types of spur gears which are categorized based on their pressure angle, i.e., 20 degrees and 14.5 degrees. The 20-degree pressure angle variant is currently best for industrial uses standards. 

Benefits Of Using Spur Gears

  • Spur gear design is very simple and compatible, so it is easy to install in limited and restricted places.
  • The product from quality gears manufacturers in India gives constant speed drive and makes it easy to control the speed of the shaft with high precision.
  • Spur gears are low-risk gears because there is no chance of slippage during the various mechanical operations, and their long life decreases the chance of premature failure.
  • The cost of fabricating the spur gear is less because of its simple design. Because of its simple design, the manufacturing and purchasing cost of this gear is also low.
  • The efficiency of the Spur gear tends to be 95% to 99%, so the power loss is very less.

Types Of Spur Gear Based On Their Teeth

1. Internal Spur Gear

Spur gears that have teeth inside their cylindrical body or disk are known as Internal Spur Gears. This internal spur gear does not pair up with another internal spur gear; it can only mesh with an external spur gear to rotate in the same direction.

2. External Spur Gear

External Spur Gear has teeth on the exterior of the disk, so it is called External Spur Gear. This gear can mesh with both an internal spur gear as well as an external spur gear.

Industries That Frequently Need Spur Gears

  • Fuel pumps
  • Hand drill
  • Machining Tools
  • Power plants
  • Washing Machines
  • Marine Engines
  • Gear pumps and Motors
  • Conveyor system
  • Speed Reducer
  • Engine and Mechanical Transportation system
