  • Application of high speed machining center in automobile production field

    introduction:For more than a decade,Structure of high speed machining center、The drive and technical performance have been greatly developed and improved。In the structure and drive mode experienced from the ball screw-Column mobile to linear motor-The second generation development of frame-in-frame structure。nowadays,The high speed machining center is moving towards merging again-Series hybrid kinematic structure development,To further improve the dynamic performance of the machining center。At present,The axial acceleration which characterizes the dynamic characteristics of high speed machining center has reached1~2g,Fast travel speed achieved80~120m/min。This creates conditions for a considerable reduction in auxiliary time。Such as:When the axial acceleration is1.2g、Fast travel speed1

  • Adjustment of clearance of NSK bearing

    introduction:Even small dust that the eye cant see,Will also giveNSKbearing[NSKbearing:Seiko Co., LTD(NSK LTD.)Be established in1916years,It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together,Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。]Bring bad effect。therefore,Keep the surroundings clean,So that dust does not invade the bearing。

  • KOYO bearings are properly installed and noise reduction methods

    introduction:1、 Low noiseKOYOBearings can also be installed and adjusted to emulate long-life bearings[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。]Group method of,The size of fit interference is more consistent,KOYOBearing clearance is also more consistent,And we want the fit interference to be a small value within the possible range,In order to ensureKOYOThe deformation of bearing raceway is small

  • Analysis of the importance of lubrication maintenance of INA imported bearings

    introduction:In order to ensureINAImported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing,ikobearing,fagbearing,Of good quality,Of course, the price is not cheap。]Normal operation of,Must have good lubrication,The load rating and speed limit of the rolling bearing are determined under the assumption of proper lubrication,The so-called appropriate lubrication refers to the appropriate selection of lubricants,Proper lubrication,Poor lubrication is often one of the main reasons for the early failure of bearings。According to statistics,about1/3The bearing is damaged because of poor lubrication。
