  • Correctly judge the running rules and faults of rolling bearings

    introduction: Rolling bearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]In the course of its use, it shows strong regularity,And repeatability is very good。Normal quality bearing(Rolling bearing)At the beginning of use,Vibration and noise are relatively small,But the spectrum is a little scattered,The amplitude is small,Probably due to some defect in the manufacturing process,As shown in table

  • Mechanical parts: wedge connection

    introduction:Wedge joint A detachable joint that uses a wedge to unite the connected parts(See picture Wedge and wedge connection )﹐It is mainly used to transfer axial force﹐Torque transfer is also possible。Wedge connection can be divided into two kinds: loose connection and tight connection。The loose wedge has no inclination﹐Loose fit in the wedge hole﹐Only one-way axial force can be transmitted。A tight wedge with a slope on one or both sides﹐Tighten the wedge during assembly﹐There is assembly stress between the connections﹐They can squeeze together and become one﹐Therefore, it can transmit the axial force of repeated action。The tight wedge slope must ensure that the wedge can lock itself into the wedge hole。Wedge connections have gradually been replaced by threaded connections or other connections。
