轴承质量辨别

网址:encodextelesystems.com  2019-12-17  作者:admin    阅读:

辨别设备轴承的质量,我们通常从以下几个方面进行:
To distinguish the quality of equipment bearings, we usually proceed from the following aspects:
1,外包装是否明晰
1, is the outer packing clear?
双列圆锥滚子轴承
Double row tapered roller bearings
双列圆锥滚子轴承图册
Double row tapered roller bearing Atlas
一般情况下,正规厂家生产的品牌都有自己专门的设计人员对外包装进行设计,并且安排生产条件过关的工厂进行制作生产,因此,产品的包装无论从线条到色块都应该是非常清晰,毫不含糊。
Generally speaking, the brands produced by the regular manufacturers have their own special designers to design the outer packaging, and arrange the factories which pass the production conditions to produce. Therefore, the packaging of the products should be very clear and unambiguous from the lines to the color blocks.
2,钢印字是否清晰
2, whether the seal is clear or not?
每一个轴承产品都会在轴承产品体上印有其品牌字样、标号等。虽然字体非常小,但是正规厂家生产的产品都采用了钢印技术印字,而且在未经过热处理之前就进行压字,因此其字体虽然小,但是凹得深,非常清晰。而通常情况下,仿冒产品的字体非但模糊,由于印字技术粗糙,字体浮于表面,有些甚至轻易地就可以用手抹去或者手工痕迹严重。
Each bearing product will have its brand name, label and so on on the bearing product body. Although the font is very small, but the regular manufacturer of products are used in steel printing technology, and before heat treatment to press the type, so although the font is small, but concave deep, very clear. In general, the fonts of counterfeit products are not only blurry, because of the rough printing technology, the fonts float on the surface, and some can be easily erased by hand or hand marks serious.
3,是否有杂响
3, is there any noise?
左手握住轴承体内套,右手小幅度的往复拨动外套使其旋转,听轴承运转过程中是否有杂响。由于大部分仿冒产品的生产条件落后,完全手工作坊式操作,在生产过程中轴承体内难免会掺进灰尘、沙子一类的杂质,所以在轴承旋转的时候会出现杂响或者运行不顺畅的现象。这一点是判断产品是否出自生产标准严格,并且用机器操作的正规厂商的品牌产品的关键。
Hold the inner sleeve of the bearing with the left hand, and move the outer sleeve with the right hand to rotate. Listen to the noise during the operation of the bearing. Due to the backward production conditions of most counterfeit products and completely manual workshop operation, it is unavoidable to mix dust, sand and other impurities into the bearing body in the production process, so when the bearing is rotating there will be noise or not smooth operation. This is the key to judging whether the product comes from a regular manufacturer's brand with strict production standards and machine operations.
4,表面
4, surface
表面是否有浑浊的油迹这需要我们在购买进口轴承时应该特别注意。由于国内的防锈技术与国外先进制造国还有一定的差距,因此对轴承体进行防锈处理时很容易留下厚厚的油迹,用手接触时感觉粘粘稠稠的,而国外原装进口的轴承上几乎看不到任何防锈油的痕迹。据业内人士介绍,特别细心的人可以在进口轴承上闻到一种特殊的味道,这就是防锈油的味道。
Whether there is turbidity on the surface, we need to pay special attention when purchasing imported bearings. There is still a certain gap between domestic anti-rust technology and foreign advanced manufacturing countries, so it is easy to leave a thick oil stain when the bearing body is treated with anti-rust. It feels sticky and thick when contacted by hand, but almost no trace of anti-rust oil can be seen on the bearings imported from abroad. According to the industry, people who are particularly careful can smell a special smell on the imported bearings, which is the smell of rust-proof oil.
5,倒角是否均匀
5, is the chamfer even?
所谓轴承的倒角,也就是横面与竖面的交接处,仿冒的轴承产品由于生产技术的限制,在这些边边角角的部位处理得不尽人意,这一点我们可以轻松辨别。
The so-called chamfering of bearings, that is, the junction of horizontal and vertical surfaces, counterfeit bearing products due to production technology constraints, in these corners and corners of the edges of the processing is unsatisfactory, which we can easily distinguish.
6,包装
6, packing
轴承包装分内包装和外包装
Bearing packaging is divided into inner package and outer package.
轴承在制造完毕并经检验合格后,即进行清洗和防锈处理,再放入内包装中,以达到防水、防潮、防尘、防冲击、维护轴承的质量和精度以及方便使用和销售的目的。
After the bearing has been manufactured and passed the inspection, it is cleaned and rust-proof, and then put into the inner packing to achieve the purpose of waterproof, moisture-proof, dust-proof, impact-proof, maintaining the quality and accuracy of the bearing, as well as convenient use and sale.
轴承内包装按防锈期分为三类:
The inner packing of bearings shall be classified into three categories according to the rust prevention period.
①短防锈期包装:防锈期3~6个月,适用于大批量发货到同一订户,短期内便投入使用的轴承。经双方协议,以方便使用为原则,采用简易包装。
(1) Short rust-proof period packing: rust-proof period 3-6 months, suitable for large-scale shipment to the same subscriber, short-term put into use of bearings. With the agreement of the two sides, simple packaging is adopted for the principle of convenient use.
②一般防锈期包装:防锈期一年,适用于一般用途的轴承。
2. General rust prevention period: the rust prevention period is one year, suitable for general purpose bearings.
③长防锈期包装:防锈期二年,适用于专用和精密轴承。
3. Long rust proof packaging: rust prevention period of two years, suitable for special and precision bearings.
轴承内包装材料有聚乙烯塑料筒(盒)、牛皮纸、平纹和皱纹聚乙烯复合纸、纸盒、聚乙烯或聚乙烯塑料膜、尼龙紧固带或塑料编制紧固带、防水高强度塑料带、麻布袋等。以上材料均需保证材料的耐腐蚀性能试验合格。
The packing materials in the bearing include polyethylene plastic cylinder (box), kraft paper, plain and wrinkled polyethylene composite paper, paper box, polyethylene or polyethylene plastic film, nylon fastening belt or plastic fastening belt, waterproof high strength plastic belt, linen bag, etc. All the above materials need to ensure that the corrosion resistance of the material is qualified.
