Reduce equivalent inertia, belt made to realize the high-speed cruising of ultralow inertia, but increase belt tightening and alleviate tensioning to
The load that belt is brought ensures stabilization of the belt in high speed variable accelerated motion, that is, ensures that draft arm does not shake, to make elastic
Shape is graceful, and the setting of active tensioning wheel and passive tensioning wheel keeps belt tension adjustment more convenient, is conducive to safeguard；Active tensioning wheel
Passive tensioning wheel side is provided with resigning groove, when belt high speed moves back and forth, retaining mechanism can pass through from groove, to
It avoids retaining mechanism from being blocked with active tensioning wheel and passive tensioning wheel, elastic draft gear is made to work normally.
2, locking mechanism structure is simple, exquisite light, greatly reduces the inertia load of belt, is conducive to the high speed of belt
Stable operation.
3, closing piece end is arranged at intervals with multiple grooves, reduces the weight of closing piece, further decreases the inertia load of belt.
4, passive tensioning wheel is made of light material, not only increases belt tightening, but also reduce equivalent inertia, ensures driving machine
The exact position response of structure at high speeds.
