Synchronous belt is under the operating mode to run at high speed, the problems such as synchronous belt device will appear from overheating, resonate, fatigue rupture, influences to test
The performance indications of platform.2nd, because belt transmission had both needed to drive heavy haul railway axle box bearing, need to drive high-speed railway axle box again
Bearing, testing stand maximum speed is typically in 3000 r/min or so.Under the overall situation of High Speed Railway Trains high speed development, bearing
Rotating speed more and more higher, by belt transmission traditional bearing testing stand rotating speed further improve will be limited in itself by belt,
This just needs more high-revolving transmission device to detect the safety and reliability of high-speed bearing.3rd, belt has certain tired longevity
Life, needs to change when reaching service life, and, it is necessary to by supporting bearing base, axially loaded machine when belt drive unit is dismantled
The mechanisms such as structure, radial loaded mechanism dismantle, sufficiently complex so that operating efficiency substantially reduces.
