两个问题搞清楚江苏INA轴承的高性能与角接触 来源:御狮轴承   点击:次   日期:2018-06-09 21:04

问题描述:

Description of the problem:

江苏INA轴承C级轴承和D级轴承有什么区别,适合高速?目前还不清楚。

What is the difference between Jiangsu INA bearing C grade bearing and D grade bearing, suitable for high speed? It's not clear at the moment.

参考答案:

Reference answer:

所谓的CD级别是江苏INA轴承调用。应该说,他们已经从1993变到现在。相应的水平分别为45,即P4P5

The so-called C and D level is the Jiangsu INA bearing call. It should be said that they have changed from 1993 to the present. The corresponding levels are 4 and 5, namely, P4 and P5.

这表明轴承的精度等级,即轴承的尺寸精度和旋转精度。P4的准确度高于P5。同时,P4轴承的热处理也应不同,其尺寸稳定性较好。

This indicates the accuracy grade of bearings, that is, the dimension accuracy and rotation accuracy of bearings. The accuracy of P4 is higher than that of P5. At the same time, the heat treatment of P4 bearing should also be different, and its dimensional stability is better.

如果在高速下使用,P4优于P5。然而,除了江苏INA轴承公差外,对高速轴承也有许多要求,如材料、热处理、润滑、甚至结构设计。

If used at high speed, P4 is better than P5. However, in addition to the INA bearing tolerances in Jiangsu, there are many requirements for high-speed bearings, such as materials, heat treatment, lubrication, and even structural design.

Description of the problem:

判断江苏INA轴承角接触球轴承的质量有什么不对?

What's wrong with judging the quality of INA bearing angular contact ball bearings in Jiangsu?

参考答案:

Reference answer:

1。表面传感轴承的质量

1. Quality of surface sensing bearing

江苏INA轴承的表面亮度应为黑色。这一亮点的原因在于轴承钢是否达到了标准。在磨削和切削液的过程中,前两个是主要的。

The surface brightness of the Jiangsu INA bearing should be black. The reason for this bright spot is whether the bearing steel has reached the standard. In the process of grinding and cutting fluid, the first two are the main ones.

2。倒角是亮的吗?

2. Is the chamfer bright?

江苏INA轴承的倒角不确定轴承的质量,但反映了Koyo角接触球轴承的加工方法。倒角为黑色,表明淬火等热处理可提高轴承的硬度。有些人认为倒角是黑色的,不是完美的。这是个误会。

The chamfer of INA bearing in Jiangsu does not determine the quality of the bearing, but it reflects the processing method of Koyo angular contact ball bearing. The chamfer is black, indicating that heat treatment such as quenching can improve the hardness of the bearing. Some people think that the chamfer is black, not perfect. This is a misunderstanding.

3,整个江苏INA轴承笼优于两体。虽然新技术采用整体式网箱,但节省材料和性能较差。

3, the whole Jiangsu INA bearing cage is superior to two body. Although the new technology adopts integral cage, it saves material and performance.
