      無錫托輥密封件游隙;即指托輥密封件在未裝置于軸或托輥密封件箱時

      托輥密封件游隙;即指托輥密封件在未裝置于軸或托輥密封件箱時;將其內圈或外圈的一方固定;然后便未被固定的一方做徑向或軸向挪動時的挪動量.依據挪動方向;可分為徑向游隙和軸向游隙.
      Clearance of the roller seal; When the roller seal is not installed on the shaft or roller seal box; Fix one side of its inner or outer ring; Then the amount of movement when the unfixed side moves radially or axially, based on the direction of movement; It can be divided into radial clearance and axial clearance
      作業時的游隙(稱做作業游隙)的巨細對托輥密封件的翻滾疲憊壽數、溫升、噪聲、振蕩等功能有影響.
      The size of the work gap (referred to as the work gap) during operation has an impact on the rolling fatigue life, temperature rise, noise, oscillation and other functions of the roller seal
      丈量托輥密封件的游隙時;為得到安穩的丈量值;通常對托輥密封件施加規則的丈量負荷.
      When measuring the clearance of the roller seal; To obtain a stable measurement value; Usually, a regular measuring load is applied to the sealing element of the roller
      因而;所得到的丈量值比真實的游隙(稱做理論游隙)大;即增加了丈量負荷發生的彈性變形量.
      Therefore; The measured value obtained is larger than the actual clearance (referred to as the theoretical clearance); This increases the elastic deformation caused by the measured load
      但關于滾子托輥密封件來說型線  流水槽模具 景觀石 檢查井鋼模具 保定通風管道 隔離墩模具 保定保潔公司;因為該彈性變形量較.裝置前托輥密封件的內部游隙通常用理論游隙表明.
      But regarding the roller carrier roller seal; Because the elastic deformation is relatively large, the internal clearance of the front roller seal of the device is usually indicated by theoretical clearance
      托輥密封件游隙的挑選
      Selection of Clearance for Roller Seals
      從理論游隙減去托輥密封件裝置在軸上或外殼內時因過盈合作發生的套圈的脹大量或縮短后的游隙稱做“裝置游隙”.
      The theoretical clearance minus the large or shortened clearance of the ring caused by interference cooperation when the roller seal device is on the shaft or inside the casing is called the "device clearance"
      在裝置游隙上加減因托輥密封件內部溫差發生的尺度變動量后的游隙稱做“有用游隙”.
      The clearance caused by adding or subtracting the scale change caused by the internal temperature difference of the carrier roller seal on the device clearance is called "useful clearance"
      托輥密封件裝置有機械上接受必定的負荷放置時的游隙;即有用游隙加上托輥密封件負荷發生的彈性變形量后的以便稱做“作業游隙”.
      The roller sealing device has clearance when mechanically placed under a certain load; The effective clearance plus the elastic deformation caused by the load on the roller seal is called the "working clearance"
      當作業游隙為微負值時;托輥密封件的疲憊壽數最長但隨著負游隙的增大疲憊壽數同明顯下降.因而;挑選托輥密封件的游隙時;通常使作業游隙為零或略為正為宜.
      When the job clearance is slightly negative; The fatigue life of the roller seal is the longest, but with the increase of negative clearance, the fatigue life also decreases significantly. Therefore; When selecting the clearance of the roller seal; It is usually advisable to set the work clearance to zero or slightly positive
      別的;需進步托輥密封件的剛性或需下降噪聲時;作業游隙要進一步取負值;而在托輥密封件溫升劇烈時;作業游隙則要進一步取正值等等;托輥密封件還必須依據運用條件做具體分析.
      other; When it is necessary to improve the rigidity of the roller seal or reduce noise; Further negative values should be taken for homework clearance; When the temperature rise of the roller seal is severe; The work gap needs to be further taken as a positive value, etc; The sealing components of the roller must also be analyzed specifically based on the application conditions
