German reca norm springs, reca norm models, reca norm prices

reca norm springs are a special type of extension spring, suitable for applications with large elongation and constant load. Constant-force springs consist of a spiral metal strip; the inner side of the strip is curved so that each coil wraps tightly around the inner coil. When the metal strip is stretched (twisted), internal stress resists the load, similar to ordinary extension springs, but the spring rate remains nearly constant (zero). See the load/torsion 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. Alternatively, the free end can be fixed, allowing the spring itself to provide the working force, similar to carbon brushes in electrical devices.

reca norm spring surface treatment

1) Black oxide: This surface treatment provides a black finish, prioritizing aesthetics over corrosion resistance. 2) Chrome plating: Chrome plating is mainly used for carbon steel products to enhance corrosion resistance. 3) Oil immersion: Oil immersion is a standard treatment for carbon steel parts to prevent rust during transportation and storage. 4) Passivation: Passivation is a cleaning method for stainless steel materials. 5) Phosphate coating: Phosphating offers better corrosion resistance than black oxide. 6) Ultrasonic cleaning: This is a standard surface treatment for stainless steel. 7) Vibratory deburring: Used to remove sharp edges from products.

reca norm spring features

1) Precise adjustment performance, meaning the relationship between force and displacement is highly sensitive; 2) Good flexibility, meaning a relatively wide range of deformation; 3) Easy manufacturing; 4) Compact structure; 5) High energy efficiency. Example characteristics: Conical helical springs offer good buffering and can withstand heavy loads. Spiral torsion springs can store more energy and withstand heavy loads, but their manufacturing process is complex. Concave helical springs have performance similar to conical helical springs and are often used in cushions and mattresses. Spring wire cross-sections include circular and rectangular shapes, with circular being the most common. Helical springs, also known as torsion springs, withstand torsional deformation, with their working part tightly wound into a spiral. The ends of torsion springs are processed into various shaped torque arms rather than hooks. Torsion springs are commonly used in balancing mechanisms in machinery and are widely applied in automotive, machine tool, and electrical industries.

reca norm spring features and applications

Features: Compared to ordinary compression or extension springs, their spring force is very constant, providing a nearly linear force output. This ensures that the product does not vary due to changes in spring force during use. In narrow spaces, they minimize space requirements, enhancing possibilities for aesthetic product design. Constant-force spring applications: Lift fans, LCD monitors, sliding windows and doors, supermarket automatic checkout counters, motor carbon brush pressure devices, cables, stapler springs, power tools, car ashtrays, locomotive carbon brush accessories, medical devices, mobile phone holders, etc.
