江苏INA轴承常见的五大裂纹影响 来源:御狮轴承   点击:次   日期:2018-07-13 20:36

江苏INA轴承的轴承体是否有杂波,左手握持轴承的轴承套,右手转动外套,以确定是否有杂波。由于大部分假冒伪劣产品的生产条件落后,车间已经完成。砂土和其他杂质不可避免地添加到生产过程中,隐藏在轴承体中,因此在旋转过程中会产生噪声。这是品牌与江苏INA轴承系列大型冷矿石振动筛的最大区别,并严格执行生产标准。

Whether the bearing body of Jiangsu INA bearing has clutter, the left hand holds the bearing sleeve of the bearing, and the right hand turns its outer sleeve to determine whether there is clutter。 As the production conditions of most fake and shoddy products are backward, the workshop has been completed。 Sand and other impurities will inevitably be added to the production process, hidden in the bearing body, so the noise will be generated during the rotation process。 This is the biggest difference between the brand and the large scale cold ore shale shaker of INA bearing series in Jiangsu, and the production standard is strictly enforced。

1。纵向裂纹的特征和形成条件在零件、原材料、碳带和显微组织偏析中经常出现。这些江苏INA轴承缺陷在纵向延伸、表面到内部裂纹、裂纹深度和长硬化层方面都不严重。能力。

1。 The characteristics and forming conditions of longitudinal cracks often occur in parts, raw materials, carbon ribbons and microstructure segregation。 These Jiangsu INA bearing defects are not serious in longitudinal extension, surface to internal crack, crack depth and long hardened layer。 Ability。

解决办法和预防措施:消除原料中的碳、组织和非过剩杂质的分离,合理开发热处理参数,尽可能对人体施加影响。

Solutions and preventive measures: eliminate the separation of carbon, tissue and non - excess impurities in the raw materials, rationally develop the heat treatment parameters, and exert influence on the human body as much as possible。

2。江苏INA轴承淬火裂纹的特征和形成条件:淬火碳化物零件或零件不常淬火,零件裂纹和叶尖间隙厚度不易发现。

2. The characteristics and forming conditions of quenching crack of INA bearing in Jiangsu: quenching carbide parts or parts are not often quenched, the crack of parts and thickness of tip clearance are not easy to find.

解决江苏INA轴承方案和预防措施:关键是要合理的热处理工艺参数,提高操作者的技能,尽可能地消除人为因素,设计最好使用弧形过渡,避免锐角。

To solve the Jiangsu INA bearing scheme and preventive measures: the key is to make reasonable heat treatment process parameters, improve the operator's skills, eliminate human factors as much as possible, and design the best use of arc transition to avoid sharp angle。

三。网状裂纹(也称为裂纹)——淬火裂纹形成的特征和条件:表面易发生磨削裂纹。高硬度、化学热处理、高频淬火等零件经常发生裂纹。江苏INA轴承零件表面裂纹约为0.0050.02 mm

Three. Mesh cracks (also known as cracks) - Characteristics and conditions of quenching crack formation: surface cracks are prone to occur. Cracks often occur in parts such as high hardness, chemical heat treatment and high frequency quenching. The surface crack of INA bearing parts in Jiangsu is about 0.005 ~ 0.02 mm.

解决方案和注意事项:回火热处理是合适的;磨料进给量小,减少磨削过程中产生的热量。

Solutions and precautions: tempering heat treatment is suitable; abrasive feed is small, reducing the heat generated during grinding.

4。裂纹和裂纹的特征和形成条件:表面硬化中经常见到的化学成分或热处理。剥离层的过渡区。

4. Characteristics and forming conditions of cracks and cracks: chemical composition or heat treatment often seen in surface hardening. The transition zone of the peeling layer.

解决方法和注意事项:淬火后立即淬火;合理选择参数和淬火介质。

Solutions and precautions: quenching immediately after quenching; reasonable selection of parameters and quenching medium。

5、微裂纹-裂纹的原因更为复杂。

5, the cause of micro crack - crack is more complex.

江苏INA轴承高碳钢、针状马氏体、奥氏体晶界和组织缺陷是裂纹的特征和形成条件。

Jiangsu INA bearing high carbon steel, acicular martensite, austenite grain boundary and microstructure defects are the characteristics and forming conditions of cracks.

解决江苏INA轴承方案和预防措施确保材料的化学成分和结构处于正常状态。必须严格控制热处理工艺参数,不断提高其技能,以弥补一些不可预见的因素,避免裂纹。

To solve the INA bearing scheme and preventive measures in Jiangsu, ensure that the chemical composition and structure of the material are in normal state. We must strictly control the heat treatment process parameters, and constantly improve their skills to compensate for some unforeseen factors and avoid cracks.
