What is a spur gear? 

We at Bengtssons Maskin are proud to offer spur gear couplings from COLOR. These spur gear couplings are at the forefront when it comes to power transmission and mechanical flexibility. A spur gear coupling is a mechanical device designed to safely and efficiently transmit torque between two shafts that are not necessarily exactly aligned. These couplings are known for their ability to handle both high torques and allow some angular misalignment without compromising performance. 

How does a spur gear coupling work?

The design of the arc tooth coupling is characterized by its arc-shaped teeth that allow a smooth and flexible connection between the coupling halves. This construction enables a high degree of axle alignment as well as absorption of shocks and vibrations.

The couplings are often greased to reduce friction and wear, extending their life and reliability. With angular error tolerances of up to +/- 0,75 degrees for standard models and even higher for special designs, these couplings offer exceptional flexibility in applications where precise shaft alignment is challenging. 

Areas of use 

Spur couplings are versatile and find use in a wide range of industrial applications. They are particularly valuable in demanding environments where large torques need to be transmitted reliably, for example in heavy industry, steel mills, and in applications with high speeds up to 40 rpm. 

 

Their robust construction makes them ideal for use in cold and hot rolling mills, where they can handle the large deflections and heavy loads that often occur. 

The advantages of helical couplings 

One of the biggest advantages of spur gear couplings is their ability to handle high torques and speeds without compromising reliability. This makes them ideal for use in applications that require exceptional performance, from high-speed applications to situations where large power transmission is necessary. Also, thanks to their design, spur gear couplings require less maintenance compared to others connection types, which leads to lower operating costs over time. 

 

On Bengtssons Maskin we understand the importance of having reliable and durable equipment in your industrial processes. Our spur gear couplings represent the latest in power transmission technology, offering superior performance, flexibility and reliability.
