First point: what is the rubber spring
      It is a mechanical part that uses elasticity to work. Generally divided into rubber spring | composite rubber spring | wire spring three. To control the movement and buffering of the parts of the machine
And shock or vibration, energy storage, measurement of the size, widely used in machinery, instrument. The variety of the spring is complex and varied. According to its shape, the main type of spring is snail.
A spring, a scroll spring, a plate spring, etc.

The second point: the function of the spring
      (1) control of the movement of the machinery, such as the valve spring in the internal combustion engine, the control spring in the clutch, etc. Absorption of vibration and shock energy, such as cars and train cars
Cushioning and damping, vibration spring in the coupling. (3) storage and output energy as a power, such as a clock spring, a spring in a gun, and so on. (4) used as a measuring force
Components, such as a dynamometer, spring in a spring scale, etc. The ratio of the load to the deformation of the spring is called the spring stiffness. The greater the stiffness, the harder the spring is.

Third point: the type of spring
      According to the properties of force, it can be divided into tensile springs, compression springs, torsion springs and bending springs. According to their shapes, they can be divided into disc springs, ring springs, plate springs, and snails.
Spiral spring, conical spiral spring and torsion bar spring. The ordinary cylindrical spring is simple in manufacture and can be made into various types according to the loading condition, and the structure is simple.
It is the most widely used. In general, the material of the spring should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance.
There are carbon spring steel, alloy spring steel, stainless steel spring steel, copper alloy, nickel alloy and rubber. Manufacturing method of spring cold roll and hot roll method. elastic
Spring wire diameter less than 8 mm by cold rolling method, greater than 8 mm by coil method. Some spring also forced or shot peening after being produced, can be improved
The bearing capacity of the spring.

Fourth point: what is a spiral spring
      A spiral spring, a torsion spring, is a spring that bears torsional deformation, and its working part is also coiled into a spiral. The end structure of the torsion spring is machined to each other
A twisted arm of a shape rather than a ring. The torsion spring is commonly used in the balance mechanism in machinery and is widely used in industrial production such as automobiles and electrical appliances.

Fifth point: what is a stretch spring
      The tensile spring is a spiral spring that bears the axial tension, and the tensile springs are usually made of circular cross section materials. In the absence of load, the ring and ring of a stretch spring
In general, there is no gap between them.

Sixth point: what is the compression spring
      A compression spring is under pressure to the spiral spring, in which the material section is round, rectangular and is also useful multi strand steel rayon coiled spring, generally for festival
From the compression spring shapes: cylindrical, conical, convex and concave and a small amount of non circular, a compression spring ring and the ring
In the gap, when the load is loaded, the spring will shrink and store the deformation energy.
