當(dāng)大量進(jìn)口徐州NSK軸承制造時(shí)，工藝系統(tǒng)通常由模板、樣品、缸體和模具來(lái)調(diào)整。在小批量生產(chǎn)中，通常使用機(jī)床上的校準(zhǔn)塊或體積塊進(jìn)行調(diào)整。調(diào)整工作的內(nèi)容也隨著工件的復(fù)雜性而變化。對(duì)于簡(jiǎn)單曲面（如內(nèi)外圓柱面），僅調(diào)整各成形運(yùn)動(dòng)的位置關(guān)系；對(duì)于復(fù)雜曲面（如螺旋面和漸開線面），也調(diào)整成形運(yùn)動(dòng)的速度關(guān)系。因此，造成進(jìn)口軸承調(diào)整誤差的因素很多。

When a large number of imported NSK bearings are manufactured in Xuzhou, the process system is usually adjusted by template, sample, cylinder block and die. In small batch production, the calibration block or volume block on the machine tool is usually used to adjust. The content of the adjustment work also changes with the complexity of the workpiece. For simple surfaces (such as inner and outer cylindrical surfaces), only the b relationship of each bing motion is adjusted; for complex surfaces (such as helical and involute surfaces), the velocity relationship of bing motion is also adjusted. Therefore, there are many factors causing the adjustment error of imported bearings.

徐州NSK軸承的測(cè)量誤差應(yīng)小于公差的10個(gè)百分比。測(cè)量誤差一般為10~33個(gè)百分點(diǎn)。隨著公差等級(jí)的增加，誤差的比例越大，即公差越小，誤差的比例越高。但是，進(jìn)口軸承的公差大于IT5，很難達(dá)到10個(gè)百分點(diǎn)。測(cè)量誤差并不意味著測(cè)試公差可以放寬10個(gè)百分點(diǎn)，而是應(yīng)該給出一定的安*全裕度，以確保用戶按照標(biāo)準(zhǔn)進(jìn)行測(cè)試。

The measurement error of Xuzhou NSK bearing should be less than 10 percent of tolerance. The measurement error is generally 10-33 percentage points. With the increase of tolerance grade, the larger the proportion of errors, that is, the smaller the tolerance, the higher the proportion of errors. However, the tolerance of imported bearings is greater than IT5, and it is difficult to reach 10 percentage points. The measurement error does not mean that the test tolerance can be relaxed by 10 percentage points, but should give a certain margin of safety to ensure that users test according to the standard.

在徐州NSK軸承零件加工的各個(gè)過(guò)程中，為了獲得軸承表面的尺寸、形狀和位置精度，需要對(duì)機(jī)床、夾具和工具進(jìn)行調(diào)整。任何調(diào)整都會(huì)不可避免地導(dǎo)致一些錯(cuò)誤。在機(jī)械加工中，對(duì)軸承零件的大規(guī)模生產(chǎn)和加工精度的要求往往不同，所采用的調(diào)整方法也不同。

In the process of processing NSK bearing parts in Xuzhou, in order to obtain the dimension, shape and b accuracy of bearing surface, it is necessary to adjust machine tools, fixtures and tools. Any adjustment will inevitably lead to some mistakes. In mechanical processing, the requirements for large-scale production and processing accuracy of bearing parts are often different, and the adjustment bs used are also different.

徐州NSK軸承孔的測(cè)量可以通過(guò)在外徑微米上用內(nèi)徑計(jì)檢查基準(zhǔn)尺寸來(lái)實(shí)現(xiàn)。同時(shí)，軸承孔的圓度和圓柱度需要測(cè)量。軸承燒損往往會(huì)減少開口處的孔徑，造成過(guò)大的圓度，這對(duì)軸承的正常運(yùn)行極為有害。如果連桿螺栓的定位面松動(dòng)，連桿的軸承蓋就會(huì)移位，軸承孔的圓度就會(huì)太大。軸承孔的圓度誤差應(yīng)控制在尺寸公差范圍內(nèi)，圓柱度應(yīng)嚴(yán)格控制。

The measurement of Xuzhou NSK bearing hole can be realized by checking the reference size with an inner diameter meter on the outer diameter micron. At the same time, the roundness and cylindricity of bearing holes need to be measured. Bearing burnout often reduces the aperture at the opening, resulting in excessive roundness, which is extremely harmful to the normal operation of bearings. If the bing surface of the connecting rod bolt is loose, the bearing cover of the connecting rod will shift and the roundness of the bearing hole will be too large. The roundness error of bearing hole should be controlled within the tolerance range of dimension, and the cylindricity should be strictly controlled.

主徐州NSK軸承孔的同軸度誤差主要由軸承孔的同軸度誤差引起，而軸承孔的同軸度誤差主要由缸體的變形引起。當(dāng)主軸頸的徑向圓跳動(dòng)在規(guī)定公差內(nèi)時(shí)，檢查主軸頸和軸承的咬痕。如果主軸承咬合痕位置明顯不同，同軸度誤差較大，可通過(guò)刮削、鏜削或更換缸體來(lái)解決。否則，很難保證發(fā)動(dòng)機(jī)的正常運(yùn)行。

The coaxiality error of the main Xuzhou NSK bearing hole is mainly caused by the coaxiality error of the bearing hole, while the coaxiality error of the bearing hole is mainly caused by the debation of the cylinder block. When the radial circular runout of the spindle journal is within the prescribed tolerance, check the bite marks of the spindle journal and the bearing. If the b of the main bearing occlusion mark is obviously different, the coaxiality error is large, which can be solved by scraping, boring or replacing the cylinder block. Otherwise, it is difficult to ensure the normal operation of the engine.
