气弹簧

压缩弹簧是承受向压力的螺旋弹簧，它所用的材料截面多为圆形，也有用矩形和多股钢萦卷制的，弹簧一般为等节距的，压缩弹簧的形状有：圆柱形、圆锥形、中凸形和中凹形以及少量的非圆形等，压缩弹簧的圈与圈之间有一定的间隙，当受到外载荷时弹簧收缩变形，储存变形能。
1.压缩弹簧设计参数
(1)压簧控制直径外径、内径、安装尺寸所套管之内径、所穿圆杆之外径。
(2)钢丝或钢杆之尺寸。
(3)材料(种类及等级)。
(4)圈数：总圈数及右旋或左旋。
(5)两末端之形式。
(6)在某一挠区长度下之负荷。
(7)一寸至几寸长度变化范围内之负荷比率。
(8)大体高“自由长。
(9)运用时之小压缩高。
图纸请注明：材料直径，外径、自由高度、总圈、工作圈数、节距、螺旋方向：有左右旋之分，常用右旋，图纸没注明的一般用右旋。有负荷要求注上负荷和对应值。
2.压缩弹簧关联标准
冷卷圆柱螺旋弹簧技术条件，GB/T2089-94等。
3.压缩弹簧特点
压缩弹簧对外载压力提供反抗力量。压缩弹簧一般是金属丝等节距盘绕和有固定的线径。压缩弹簧利用多个开放线圈对外载压力(如重力压下车轮，或者身体压在床褥上)供给抵抗力量。也是，他们回推以反抗外部压力。压缩弹簧一般是金属丝等节距盘绕和有固定的线径。此外，也有圆锥形的压缩弹簧，或者圆锥和直线型组合的弹簧。根据不同的应用领域，压缩弹簧可用于抵抗压力和(或)存储能量。圆形金属丝是压缩弹簧常用的，但也有正方形、长方形和特殊形状的金属丝制造出的压缩弹簧。
4.压缩弹簧的应用
医疗呼吸设备、医疗移动设备、手工工具、家庭护理设备、减震、发动机气门弹簧。

A compression spring is under pressure to the spiral spring, the cross section of the material are round, rectangular and is also useful for multi-strand steel rayon coiled spring, generally for pitch, a compression spring shapes: cylindrical, conical, barrel shaped and concave and a small amount of non circular, compression spring ring and the ring has a certain gap, when subjected to external load spring shrinkage deformation, deformation energy storage.
1 compression spring design parameters
(1) the pressure spring controlling diameter, diameter, the diameter of the sleeve installation to ensure the size, the outer diameter of the wear round rod.
(2) wire or bar size.
(3) material(type and grade).
(4) number of laps: total number of coils and dextral or sinistral.
(5) the two end of the form.
(6) in a deflection zone length under load.
(7) of an inch to several inches of length variation range of load ratio.
(8) the maximum height" free length.
(9) using the minimum compression high.
The drawings please specify: material diameter, outside diameter, height, total laps laps, work, pitch, spiral direction : a right or left-hand, right-hand drawings used, did not specify general with dextral. A load demand note on load and the corresponding value.
2 compression springs Association standard
Cold coiled helical springs technical specifications, GB/T2089-94 etc..
3 compression spring characteristics
Compression spring loaded pressure resistance strength of foreign. A compression spring is generally metal wire pitch coiled and fixed line diameter. The use of a compression spring more open coil external load pressure(such as gravity pressing wheel, or the body pressure in the mattress)supply resistance forces. That is, they pushed back against external pressure. A compression spring is generally metal wire pitch coiled and fixed line diameter. In addition, also has a conical compression spring, or conical and linear combinations of spring. According to different application, the compression spring can be used for pressure resistance and(or)for energy storage. Round wire compression spring is the most commonly used, but there are square, rectangular and special shaped wire manufacturing a compression spring.
4 Application of compression spring
Medical respiratory equipment, mobile equipment, hand tools, medical equipment, home care, engine valve spring shock absorber.
