螺纹精度等级
螺纹精度等级•螺纹精度等级,螺纹的精度等级螺纹精度等级1、公制(din、iso、gb)分为6h、6g等级。
通常状况下是6h级。
公制日标(jis)分为ⅰ级、ⅱ级、ⅲ级等三种。
通常状况是ⅱ级。
2、英制为1b、2b、3b通常状况下是2b等级。
3、目前攻牙使用到的牙攻之牙山角度为二种:60度和55度,60度有公制牙 ...•螺纹精度等级?纹等级:5h、6h、7h。
(日标螺纹精度等级分为i、ii、iii三级,通常状况下为ii级)在公制螺纹中,h和h的基本偏差为零。
g 的基本偏差为正值,e、f和g的基本偏差为负值。
如图所示:1、h是内螺纹常用的公差带位置,一般不用作表面镀层,或用极薄的磷化层。

紧固件常用规格
公制内螺纹(6H)常用规格极限尺寸表(粗牙)公制外螺纹(6g)常用规格极限尺寸表(细牙)公制外螺纹(6g)常用规格极限尺寸表(粗牙)垫圈材料的选择在螺纹紧固件中因螺栓、螺钉、螺母的支承面不可能做得很大(受材料与工艺的限制),为减小承压面的压应力,保护被连接件的表面而采用垫圈。
为防止连接副的松动采用防松的弹簧垫圈和多齿形锁紧垫圈、圆螺母止动垫圈以及鞍形、波形、锥形弹性垫圈。
平垫圈主要用于减小压强,当有的部位拧紧轴向力很大时,易使垫圈压成碟形,这时可改用材料和提高硬度来解决。
弹簧垫圈的锁紧效果一般,重要部位尽量少用或不用,而采用自锁结构。
对于用于高速拧紧(气动或电动)的弹簧垫圈,最好采用表面磷化处理的垫圈,提高其减磨性能,否则易摩擦发热而烧坏或张口,甚至损坏被连接件表面。
对于薄板连接处,不应采用弹簧垫圈结构。
据统计,弹簧垫圈在汽车上使用得越来越少了。
齿形弹性垫圈中的连接齿形由于锁紧力大而且均匀,在汽车行业中使用较多,而间隔齿型的则少一些。
对于弹簧垫圈、弹性垫圈,根据国标,一般可选择GB699-1999 《优质碳素结构钢》中的60 、70 钢和65Mn 钢。
我国平垫圈标准共有9项,从2000-2002年分别批准发布了GB/ T97.3-2000、GB/T5286-2001、GB/T95-2002、GB/T96.1-2002、G B/T96.2-2002、GB/T97.1-2002、GB/T97.2-2002、GB/T97.4-20 02及GB/T5287-2002 等平垫圈标准。
根据平垫圈性能等级,作者推荐使用材料:对于100HV级的可选用ST12、ST13及Q235、Q215、Q195等等,表面硬度可达到110HV 左右;对于140HV级的可选用08F、08Al及10、10F等等,表面硬度可达到140HV左右;对于200HV和300HV级的应选用45、50、60、70钢或65Mn钢,可通过热处理淬火回火达到200~300HV和300~400HV技术要求。
