A tyre coupling is an elastic coupling and consists of a flexible element—the tyre—and two coupling halves, also referred to as the hub or flange. The coupling half is made from cast iron and is available in both pre-drilled and clamping bush variants for quick installation and removal. In the latter case, the hub has a conical bore for the clamping bush.
The flexible element consists of a rubber composite as standard; this composite is suitable for a temperature range from -50°C to +50°C. The element is also available in a chloroprene variant, which meets the FRAS guidelines (fire-resistant and antistatic) and also has a greater resistance to oil and heat. This variant is suitable for a temperature range from -15°C to +70°C.
To produce a complete ATEX-certified tyre coupling, the flexible FRAS-compliant element must be used together with coupling halves that have been specially modified for this purpose. Our product specialists can give you more detailed information on this.
As tyre couplings are flexible, they can compensate for significant angle errors and have a vibration and impact-damping effect. Furthermore, they are extremely adaptable for a range of alignment errors and they are also maintenance-free. They are also suitable for dirty environments, for example for those contaminated by oil or grease.
Tyre couplings are also available on request as models with a spacer or flywheel.
Current standards for shaft couplings are DIN 740, DIN 115 and DIN 116.
