镇江INA轴承NA4860妥当与否的噪声根源

1，镇江INA轴承安装场地须保持清洁。的工作和服务寿命防止灰尘是非常重要的，影响轴承的污染物和水分含量。

1, Zhenjiang INA bearing installation site must be kept clean. The work and service life to prevent dust is very important, affecting the bearing's pollutants and moisture content.

2。检查轴承孔和轴的配合面，如尺寸精度和清洁度。

2. Check the mating surfaces of bearing holes and shafts, such as dimensional accuracy and cleanliness.

三。在轴承套圈的配合面上涂抹少量油或润滑脂。

Three. Apply a ***all amount of oil or grease to the mating surface of the bearing ring.

4，轴和轴承孔有10到15度的导向倒角。

4, the shaft and bearing bore h***e 10 to 15 degrees of guide chamfering.

5。冷凝会导致轴承和轴承表面生锈，所以不要过冷轴承。

5. Condensation causes rust on bearing and bearing surfaces, so do not undercooled bearings.

6。安装后，在钻具镇江INA轴承上安装润滑剂，检查轴承设备是否正常工作。

6. After installation, lubricant is installed on the INA bearing of the drill tool, and check whether the bearing equipment is working normally.

轴承的加热温度取决于轴承的尺寸和所需的干扰。在热装操作中应注意的几个方面如下：

The heating temperature of the bearing depends on the size of the bearing and the required interference. Several aspects that should be noted in the hot charging operation are as follows:

1，不要将轴承加热到120摄氏度。

1, do not heat the bearing to 120 degrees Celsius.

2。为了防止轴承直接接触油槽底部，考虑钻头轴承双金属轴承或升降平台。

2. In order to prevent the bearing from contacting the bottom of the oil tank directly, we c***ider the bit bearing double metal bearing or lifting platform.

三。加热钻头轴承温度20-30摄氏度，防止内部的环从操作和安装难度以上的。

Three. The drill bit bearing temperature is 20-30 degrees Celsius, preventing internal ring from operation and installation difficulty above.

4。安装后，轴承，宽度变短。轴螺母或其余合适的固定方法可用于防止内圈与轴承肩之间的间隙。

4. After installation, the bearing width is shortened. The shaft nut or other suitable fixing methods can be used to prevent the clearance between the inner ring and the bearing shoulder.

镇江INA轴承保持架材料所需的性能：

Properties of Zhenjiang INA bearing cage material:

尺寸稳定性好，机械强度高。

Good dimensional stability and high mechanical strength.

此外，良好的可加工性是必要的。根据其用途不同，还需要耐冲击性、耐热性和耐腐蚀性。

In addition, good workability is necessary. It also needs impact resistance, heat resistance and corrosion resistance according to its different uses.

轴承套圈和滚动件用材料：

Materials for bearing rings and rolling parts:

环和辊通常由高碳铬轴承钢制成。大多数轴承在JIS钢中使用SUJ2。大型轴承配备SUJ3。

Rings and rollers are usually made of high carbon chromium bearing steel. Most bearings use SUJ2 in JIS steel. Large bearings are equipped with SUJ3.

在进一步的冲击过程，铬钢、铬钼钢、铬镍钼钢作为渗碳淬火的轴承材料，使钢具有良好的表面硬化层层次。渗碳轴承有合适的淬火层次、精细结构、表面硬度和中点的硬度，并且更耐冲击比轴承钢轴承。镇江INA轴承渗碳轴承钢的化学成分一般良好。

In the further impact process, chromium steel, chromium molybdenum steel, chromium nickel molybdenum steel as carburized and quenched bearing materials, so that the steel has a good surface hardening layer. Carburized bearings h***e suitable quenching levels, fine structure, surface hardness and midpoint hardness, and are more impact resistant than bearing steel bearings. The chemical composition of INA bearing carburized bearing steel in Zhenjiang is generally good.

轴承保持架材料：

Bearing cage material:

笼中使用的材料是低碳钢。根据它们的不同用途，也使用黄铜板和不锈钢板。切割笼材料由强度黄铜和碳钢制成，还使用合成树脂。

The material used in the cage is low carbon steel. According to their different uses, brass plates and stainless steel plates are also used. The cutting cage material is made of strength brass and carbon steel, and synthetic resin is also used.
