In the "family" of mechanical transmission, tire couplings stand out with their unique "flexible" design, playing a crucial role in achieving smooth and shock-resistant transmission in the industrial field.

Its core structure consists of a tire-shaped rubber elastic element and metal half couplings. The rubber element is tightly bonded to the metal flange through vulcanization, forming a transmission unit that can not only transfer torque but also accommodate displacement and buffer vibrations. Its working principle is to utilize the elastic deformation of the rubber tire to compensate for radial, angular, and axial misalignments between two shafts, while absorbing shocks and vibrations during operation, ensuring a smoother power transmission.

The advantages of tire couplings are quite prominent: Firstly, they have an extremely strong ability to buffer and absorb vibrations, effectively reducing the impact loads from equipment such as crushers and steel rolling mills, protecting the transmission system. Secondly, they offer a large displacement compensation capacity, far exceeding many other couplings in their ability to compensate for radial and angular displacements, thus lowering the precision requirements for equipment installation. Thirdly, they operate smoothly with low noise, as the damping effect of rubber can suppress torsional vibrations. Fourthly, they have a simple structure that is easy to maintain, require no lubrication, and the rubber elements can be replaced individually when worn, saving maintenance costs.

In terms of application scenarios, they are widely used in heavy machinery, mining equipment, metallurgy, marine propulsion systems, and other fields. For instance, in steel rolling production lines, they connect motors to rolls, buffering the impact of steel rolling; in marine propulsion systems, they compensate for installation errors in the shafting; and in crushers, they mitigate the damage caused by material impacts to the equipment.

When selecting tire couplings, attention should be paid to the torque to be transmitted, rotational speed, displacement requirements, and operating conditions. If the operating temperature is too high or there are corrosive media, special rubber materials should be chosen.

With the "flexibility" of rubber, tire couplings complement the "rigidity" of metal transmission, serving as both "shock absorbers" and "displacement regulators" for equipment while transmitting power. They are one of the core components in industrial transmission systems for achieving flexible and reliable transmission.
