rengasliitin

A rengasliitin, often translated as a "tire connector" or "tire coupling," is a type of mechanical coupling used to connect rotating shafts. It is characterized by the use of a flexible rubber or synthetic material ring, or "rengas," as the primary torque-transmitting element. This ring is typically sandwiched between two metal hubs, which are then attached to the shafts they are intended to connect.

The flexibility of the rubber ring allows the rengasliitin to accommodate misalignment between the connected shafts. This misalignment can be angular, parallel, or a combination of both, which is a common issue in many industrial applications. By absorbing these misalignments, the rengasliitin helps to reduce stress on the connected machinery, thereby extending its operational life and minimizing the need for frequent maintenance.

Rengasliittimet are known for their ability to dampen vibrations and shocks. The elastic nature of the rubber ring absorbs energy from the system, resulting in smoother operation and reduced noise levels. This makes them suitable for applications where vibration and noise are a concern. They also offer a degree of electrical insulation between the connected shafts.

The design of a rengasliitin typically involves two or more radially extending jaws or teeth on each hub that engage with the flexible ring. The torque is transmitted through the compression of the ring material between these jaws. They are relatively simple in construction, making them cost-effective and easy to install. Common applications include pumps, motors, compressors, and various types of industrial machinery.
