南京NSK轴承6212游隙冷却测量法

南京NSK轴承的安装是正确的，影响精度、寿命和性能。因此，设计和装配部门应充分研究轴承安装。我们希望按照操作标准安装。操作标准项目通常如下：

The installation of NSK bearings in Nanjing is correct, affecting accuracy, life and performance. Therefore, the design and assembly department should fully study the bearing installation. We hope to install according to the operation standard. Operating standard items are usually as follows:

（1）清洗轴承和轴承相关部件。

(1) cleaning bearing and bearing related components.

（2）检查有关零件的尺寸和精整。

(2) check the dimensi*** and finishing of the parts concerned.

（3）安装

(3) installation

（4）轴承安装后的检查。

(4) inspection after bearing installation.

（5）供应润滑剂

(5) supply lubricants

希望南京NSK轴承包装在安装前打开。普通润滑脂润滑，不清洗，直接填充油脂。润滑剂润滑，一般不需要清洗，但仪器或高速进口轴承，要用干净的油清洗，去除轴承上的防锈涂层。除锈剂易生锈，不可忽视。此外，轴承轴承润滑脂不直接清洗和使用。

I hope Nanjing NSK bearing packing will be opened before installation. Ordinary grease is lubricated, not cleaned, directly filled with grease. Lubricant lubrication, generally do not need to be cleaned, but the instrument or high-speed imported bearings, to clean with clean oil, remove the anti-rust coating on the bearing. Rust remover is easy to rust and can not be ignored. Besides, bearing bearing grease is not directly cleaned and used.

轴承的安装方法，由于轴承的结构、配合、条件不同，一般来说，由于大部分轴的转动，所以内圈需要过盈配合。圆柱孔轴承通常用压力机压紧或压紧。锥形孔直接安装在锥形轴上或提供套筒。

Bearing installation method, because the bearing structure, fit, conditi*** are different, generally speaking, because most of the shaft rotation, so the inner ring needs interference fit. Cylindrical bore bearings are usually pressed or pressed by a press. The tapered holes are directly mounted on the conical shaft or provided with sleeves.

当安装在壳体上时，总间隙越大，冷却后的外圈通常会受到压力或收缩。当干冰被用作冷却剂和冷收缩与安装相结合时，空气中的水分将凝结在南京NSK轴承的表面上。因此，需要采取适当的防锈措施。

When installed on the shell, the greater the total gap, the outer ring after cooling will usually be subjected to pressure or contraction. When dry ice is used as a coolant and combined with cold shrinkage and installation, moisture in the air will condense on the surface of Nanjing NSK bearings. Therefore, appropriate anti rust measures need to be taken.

在一些高温环境中，经常需要大间隙高温轴承，但用户如何测量南京NSK轴承的径向游隙？以下是简要介绍：

In some high temperature environments, large clearance high temperature bearings are often required, but how do users measure the radial clearance of Nanjing NSK bearings? The following is a brief introduction:

（1）在测量过程中，应确保球落到槽底，关闭前应测量封闭轴承。当负载被计时时，由负载引起的间隙应该从测量值中减去。

(1) during the measurement process, the ball should be ensured to fall to the bottom of the trough and closed bearings should be measured before closing. When the load is timed, the gap caused by the load should be subtracted from the measured value.

（2）对于多排轴承，要求每个行间隙合格，并将每个行间隙的算术平均值作为轴承的径向间隙。

(2) For multi-row bearings, each row clearance is required to be qualified, and the arithmetic ***erage of each row clearance is taken as the radial clearance of the bearing.

（3）尝试使用专用仪器测量方法。

(3) try to use the special instrument measuring method.

（4）人工测量要求测量人员具有较高的测量南京NSK轴承技能。测量误差较大，特别是当间隙处于边缘状态时。此时，应以仪器测量为标准。

(4) manual measurement requires that the surveyors h***e a high measurement of Nanjing NSK bearing skills. The measurement error is large, especially when the gap is at the edge state. At this point, instrument measurement should be taken as the standard.

（5）在测量柱塞规时，应按标准进行操作。以前的测量方法不应该从柱塞塞规反转。

(5) when measuring the plunger gauge, it should be operated according to the standard. Previous measurement methods should not be reversed from plunger plug gauge.
