German linmot springs linmot models linmot prices

linmot springs are conical disc-shaped and can be used individually or in series or parallel combinations. They withstand static or dynamic axial loads at the upper inner edge and lower outer edge, deforming under compression until flattened to store energy as a live load. When necessary, they automatically convert into additional compressive load required for sealing, reducing the continuous tightening requirements for gaskets and packing. Disc springs are special springs that are conical in the axial direction and bear loads; after deformation under load, they store potential energy. When bolts loosen, the disc spring releases part of the potential energy to maintain pressure between flange connections to meet sealing requirements. The stress distribution of disc springs decreases uniformly from inside to outside, achieving high compensation force with low travel.

linmot spring surface treatment

1) Black oxide treatment: This surface treatment provides a black surface; black oxide is primarily for aesthetic improvement rather than corrosion resistance. 2) Chrome plating: Chrome plating is mainly applied to carbon steel products to increase corrosion resistance. 3) Oil impregnation: Oil impregnation is the standard treatment for carbon steel products 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 the standard surface treatment for stainless steel materials. 7) Vibratory deburring: To remove sharp edges from products.

linmot spring structural classification

Based on loading characteristics, springs can be classified into tension springs, compression springs, torsion springs, and bending springs. By shape, they include disc springs, ring springs, leaf springs, helical springs, truncated conical volute springs, and torsion bar springs. By manufacturing process, they are divided into cold-coiled and hot-coiled springs. Ordinary cylindrical springs are widely used due to their simple manufacturing, adaptable forms based on load conditions, and simple structure. Spring materials generally require high elastic limit, fatigue limit, impact toughness, and good heat treatment performance. Common materials include carbon spring steel, alloy spring steel, stainless spring steel, copper alloys, nickel alloys, and rubber. Manufacturing methods include cold coiling and hot coiling. Spring wire diameters less than 8 mm are generally cold-coiled, while those greater than 8 mm are hot-coiled. Some springs undergo strong pressing or shot peening after manufacturing to improve load-bearing capacity.

linmot spring applications

1) For blacksmiths: Because leaf springs are made of higher-quality steel, they are a preferred material for blacksmiths. In countries like Nepal, Bangladesh, the Philippines, and Pakistan, where traditional blacksmithing still produces many tools, discarded vehicle leaf springs are often used to make knives and other tools. 2) Used in trampolines: Leaf springs have replaced traditional helical springs in some trampolines (known as soft-edge trampolines), improving user safety and reducing the risk of concussion. Leaf springs are spaced around the frame 'legs', branching from the base frame to suspend the jumping mat, thereby providing elasticity. 3) Used in clutches: The common 'diaphragm' in automotive clutches is a type of leaf spring.
