AOBOTE bearing Limited Company was founded in 1998，With Distributor For Wholesale Skf 6314-2RS Bearings in stock with an favorable price,AOBOTE has build worldwide sourcing bearing network,Following with imported bearing experts for customers to solve professional problems and many improted bearing brand,like skf,fag,nsk,timken,ina,ntn,nsk and so on to satisfy customers’ different needs.Which can provide all variety of bearing,consists of Deep Groove Ball Bearing、Taper Roller Bearings、Spherical Roller Bearing、Needle Roller Bearing、Angular Contact Ball Bearing、Cylindrical Roller Bearing、Thrust Roller Bearing,and The other.Today we will talk about The application of TM polymer in the spindle bearing.
On main shaft bearing of 5000 r/min long work used the constant temperature tank cooling measures, but found that the main shaft increase noise, cooling effect is poor, the spindle speed is far from the design requirements of 8000 r/min, and found that the individual ball bearings, raceway burns and hair. According to FC ball of centrifugal force and gyroscopic moment formula of MG, ball under the condition of high speed, centrifugal force and gyroscopic moment is proportional to the increase, namely
FC ∝ wc2
MG ∝ wcwbsin beta.
Type in the wc - rolling orbital angular velocity, (°)
Wb - rolling rotation angular velocity, (°)
Beta - Angle to the public with the Angle, the Angle between the (°)
Bearings between the ball and the raceway of the relative sliding friction heat is increased, the phenomenon such as burns, hair.
To this end, our factory made using TM test of polymer spindle bearing lubrication. TM polymer is a kind of suspension using high-tech production of superfine metal elements.
To examine the TM lubricating properties of polymer, as shown in figure 1 device is adopted to improve the wear-resisting, withstand voltage test.
