壓縮彈簧是承受向壓力的螺旋彈簧，它所用的材料截面多為圓形，也有用矩形和多股鋼縈卷制的，彈簧一般為等節(jié)距的，壓縮彈簧的形狀有：圓柱形、圓錐形、中凸形和中凹形以及少量的非圓形等，壓縮彈簧的圈與圈之間有一定的間隙，當(dāng)受到外載荷時(shí)彈簧收縮變形，儲(chǔ)存變形能。
1.壓縮彈簧設(shè)計(jì)參數(shù)
(1)壓簧控制直徑外徑、內(nèi)徑、安裝尺寸所套管之內(nèi)徑、所穿圓桿之外徑。
(2)鋼絲或鋼桿之尺寸。
(3)材料(種類及等級(jí))。
(4)圈數(shù)：總?cè)��?shù)及右旋或左旋。
(5)兩末端之形式。
(6)在某一撓區(qū)長(zhǎng)度下之負(fù)荷。
(7)一寸至幾寸長(zhǎng)度變化范圍內(nèi)之負(fù)荷比率。
(8)大體高“自由長(zhǎng)。
(9)運(yùn)用時(shí)之小壓縮高。
圖紙請(qǐng)注明：材料直徑，外徑、自由高度、總?cè)Α⒐ぷ魅��?shù)、節(jié)距、螺旋方向：有左右旋之分，常用右旋，圖紙沒注明的一般用右旋。有負(fù)荷要求注上負(fù)荷和對(duì)應(yīng)值。
2.壓縮彈簧關(guān)聯(lián)標(biāo)準(zhǔn)
冷卷圓柱螺旋彈簧技術(shù)條件，GB/T2089-94等。
3.壓縮彈簧特點(diǎn)
壓縮彈簧對(duì)外載壓力提供反抗力量。壓縮彈簧一般是金屬絲等節(jié)距盤繞和有固定的線徑。壓縮彈簧利用多個(gè)開放線圈對(duì)外載壓力(如重力壓下車輪，或者身體壓在床褥上)供給抵抗力量。也是，他們回推以反抗外部壓力。壓縮彈簧一般是金屬絲等節(jié)距盤繞和有固定的線徑。此外，也有圓錐形的壓縮彈簧，或者圓錐和直線型組合的彈簧。根據(jù)不同的應(yīng)用領(lǐng)域，壓縮彈簧可用于抵抗壓力和(或)存儲(chǔ)能量。圓形金屬絲是壓縮彈簧常用的，但也有正方形、長(zhǎng)方形和特殊形狀的金屬絲制造出的壓縮彈簧。
4.壓縮彈簧的應(yīng)用
醫(yī)療呼吸設(shè)備、醫(yī)療移動(dòng)設(shè)備、手工工具、家庭護(hù)理設(shè)備、減震、發(fā)動(dòng)機(jī)氣門彈簧。

中譯英：
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.
