2、螺栓：配用螺母的圓柱形帶螺紋的緊固件，有六角頭的，圓頭的，方形頭的，沉頭的等等。 </p> <p> <br /> </p> <p> 3、螺帽（螺母）：一般為扁平中空的多面柱體結(jié)構。 </p> <p> <br /> </p> <p> 二、作用不同 </p> <p> <br /> </p> <p> 1、螺絲：利用物體的斜面圓形旋轉(zhuǎn)和摩擦力的物理學和數(shù)學原理，循序漸進地緊固器物機件的工具。 </p> <p> <br /> </p> <p> 2、螺栓：機械零件，配用螺母的圓柱形帶螺紋的緊固件。由頭部和螺桿（帶有外螺紋的圓柱體）兩部分組成的一類緊固件，需與螺母配合，用于緊固連接兩個帶有通孔的零件。 </p> <p> <br /> </p> <p> 3、螺帽（螺母）：螺母（螺帽）是將機械設備緊密連接起來的零件，通過內(nèi)側(cè)的螺紋，同等規(guī)格螺母和螺栓才能連接在一起。 </p> <p> <br /> 肇慶螺栓電話地腳螺栓有什么用，它是怎么工作的？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

剪力螺栓，就是能夠承受較大剪力的這種螺栓。而一般的螺栓，承受的是拉力，只能承受很小的剪力。 </p> <p> 零件與零件之間經(jīng)常會有受到平行的且方向相對的力，這種力較小時用一般螺栓即可，由零件之間的摩擦力平衡掉。但有的時候受到的這種力很大，摩擦力不足以平衡，這時就需要用剪力螺栓了。例如：起重機的吊臂上的螺栓，很多就是剪力螺栓。 </p> <p> <br /> </p><p> 螺栓檢測分為人工和機器兩種。人工是原始也是使用為普遍的一致檢測方式。為了盡量減少不良品的流出，一般生產(chǎn)企業(yè)人員通過目視的方式對待包裝或者發(fā)貨的產(chǎn)品進行檢驗，以排除不良品（不良包括牙傷、混料、生銹等）。 </p> <p> <br /> </p> <p> 另一種方式為機器全自動檢測，主要是磁粉探傷。磁粉探傷是利用螺栓缺陷處的漏磁場與磁粉的相互作用，針對螺栓可能存在的缺陷（如裂紋，夾渣，混料等）磁導率和鋼鐵磁導率的差異。 </p> <p> <br /> </p> <p> 磁化后這些材料不連續(xù)處的磁場將發(fā)生崎變，形成部分磁通泄漏處工件表面產(chǎn)生了漏磁場，從而吸引磁粉形成缺陷處的磁粉堆積——磁痕，在適當?shù)墓庹諚l件下，顯現(xiàn)出缺陷位置和形狀，對這些磁粉的堆積加以觀察和解釋，已達到剔除不良品的目的。 </p> <p> <br /> 螺栓按連接的受力方式分為哪些？</p><div

**度螺栓摩擦型和承壓型連接的區(qū)別： </p> <p> **度螺栓連接具有施工簡單、受力性能好、可拆換、耐疲勞、以及在動力荷載作用下不致松動等優(yōu)點，是很有發(fā)展前途的連接方法。 </p> <p> **度螺栓是用特制的扳手上緊螺帽，使螺栓產(chǎn)生巨大而又受控制的預拉力，通過螺帽和墊板，對被連接件也產(chǎn)生了同樣大小的預壓力。在預壓力作用下，沿被連接件表面就會產(chǎn)生較大的摩擦力，顯然，只要軸力小于此摩擦力，構件便不會滑移，連接就不會受到破壞，這就是**度螺栓連接的原理。 </p> <p> <br /> 螺栓使用過程中的注意事項有哪些？肇慶螺栓電話</p><p
