南京INA轴承目的鲜明的组件配合 来源:御狮轴承   点击:次   日期:2018-08-17 14:37

南京INA轴承与轴或轴承座匹配的目的是将内外环牢固地固定在轴或轴承座上,以避免有害滑动。

The purpose of matching the Nanjing INA bearing with the shaft or bearing seat is to firmly fix the inner and outer rings on the shaft or bearing seat to avoid harmful sliding.

如果配合面滑动,会发生异常的发热和磨损,以及磨损粉末进入轴承造成的早期损坏和振动,导致轴承不能充分发挥其作用。

If the mating surface slides, abnormal heating and wear will occur, as well as wear powder into the bearing caused by early damage and vibration, resulting in the bearing can not fully play its role.

此外,南京INA轴承的组合会影响轴承的径向游隙,径向游隙不仅关系到轴承的运行精度,而且影响其寿命。

In addition, the combination of Nanjing INA bearings will affect the radial clearance of bearings, radial clearance is not only related to the operational accuracy of bearings, but also affects their life.

滚动轴承是一个标准件,因此滚动轴承的内径和外径是与相关零件匹配时的基准孔和轴,因此在匹配时不需要标记。决定合作的最重要的问题是南京INA轴承的内外环的载荷状态。

The rolling bearing is a standard part, so the internal and external diameters of the rolling bearing are the reference holes and shafts when matching with the relevant parts, so no marking is required in matching. The most important problem that decides cooperation is the load status of the inside and outside ring of Nanjing INA bearing.

一般来说,在大尺寸、大载荷、大振动、高速或高工作温度的情况下,有必要加强一些匹配,并且经常拆装或使用游泳环更加松散匹配。

Generally speaking, in the case of large size, large load, large vibration, high speed or high working temperature, it is necessary to strengthen some matching, and often disassemble or use the swimming ring more loosely matching。

1。尺寸标准要求

1. Dimensional standard requirements

在采用比较测量法测量轴承尺寸公差时,规定测量块或标准件应作为比较测量的尺寸基准,其中测量块必须符合JB/T1078“测量块”标准和标准。D部分必须符合制造商部门的要求。

When measuring bearing dimension tolerance by comparative measurement method, it is stipulated that the measuring block or standard part should be used as the dimension datum of comparative measurement, in which the measuring block must conform to the JB/T1078 "measuring block" standard and standard。 The D part must comply with the requirements of the manufacturer department。

2。测量仪器的要求

2. Requirements for measuring instruments

测量中所用的仪器必须校准,并适合测量南京INA轴承的精度和放大率。

The instruments used in the measurement must be calibrated and suitable for measuring the accuracy and magnification of Nanjing INA bearings.

三。测量面积要求

Three. Measurement area requirement

对于南京INA轴承内径或外径的测量,规定测量应在与环的南端分离的最大倒角坐标区域中,测量应位于R的南端的双倒角坐标区域F。英寸初始导航和引导。在海洋之外。

For the measurement of the inner diameter or outer diameter of Nanjing INA bearing, it is stipulated that the measurement should be in the maximum chamfered coordinate region separated from the southern end of the ring, and the measurement should be in the double chamfered coordinate region F at the southern end of R。 Inch initial navigation and boot。 Beyond the ocean。

4。允许测量误差

4. Allowable measurement error

原则上,测量误差可以容忍小于10%的公差。

In principle, measurement errors can tolerate tolerances less than 10%.

5。探头半径和量规压力。

5。 Probe radius and gauge pressure。

为了减小测量误差,需要减小测量仪器的压力测量压力,并将探头的曲率半径增加到可能的范围。

In order to reduce the measurement error, it is necessary to reduce the pressure measurement pressure of the measuring instrument and increase the curvature radius of the probe to a possible range.
