German rft springs rft models rft prices
rft springs are a special type of extension spring, suitable for applications with large elongation and constant load. Constant-force springs consist of spiral metal strips; the inner side of the strip is curved so that each coil wraps tightly around the adjacent inner coil. When the metal strip is stretched (twisted), internal stress resists the load force, similar to ordinary extension springs, but the spring rate remains nearly constant (zero). See the load/torque diagram. In use, an ID is typically used to wind this spring tightly onto a drum, with its free end connected to the load, acting like a counterweight.
rft rubber vibration isolator, Germany rft model, rft price
The rft rubber vibration isolator consists of a smooth bellows compensation element with rubber flanges at both ends and metal flanges. The metal flanges often adopt a loose structure. The surface of the bellows compensation element is rubber, and the inner layer is a laminate reinforced with several layers of high-strength fiber or steel strips (wires). The reinforcing layers, such as reinforcing fibers or steel strips (wires), extend all the way to the rubber flanges at both ends, which contain a hard steel wire skeleton. The rubber expansion joint has a large displacement compensation capacity, capable of compensating for axial, lateral, and angular displacements. It features noise reduction, vibration damping, and certain corrosion resistance. It offers high pressure resistance, good elasticity, and displacement
