In loading board；The middle part bias of the eccentric wheel offers through-hole and eccentric wheel is socketed in the fixing axle via the through-hole,
The rotation section rotationally cuff on the periphery of the eccentric wheel；The detachable fastening unit is fixedly connected described solid
Dead axle and eccentric wheel.
The detachable fastening unit 3 is locknut；The fixing axle is located at eccentric wheel far from the mounting plate one
The end of side is provided with external screw thread, and it is described to which the eccentric wheel to be anchored on that locknut is threadedly connected to the end of fixing axle
In fixing axle.Cuff has deep groove ball bearing on the eccentric wheel, and the outer ring of deep groove ball bearing forms the rotation section 4.
When carrying out tensioning adjusting, locknut, rotation eccentric wheel to suitable position, so that transmission belt are unclamped
Tightly, locknut is then tightened, prevent eccentric wheel relative to fixing axle from rotating.
Embodiment 2:
The main structure of embodiment 2 is same as Example 1, and only embodiment 1 needs to utilize spanner when adjusting eccentric wheel
Release locknut then adjusts eccentric wheel and the location status of eccentric wheel is difficult to fix in adjustment process, is unfavorable for testing
Row tightens locknut to personnel again；Based on this, embodiment 2 replaces detachable fastening unit, specifically, replacement
Detachable fastening unit afterwards includes movable axis 31, guide rod 32, adjusting rod 33, compressed spring 34, locking lid 35 and adjusts
Save end cap 36；The fixing axle is the hollow shaft axially inside penetrated through, and the two-port of fixing axle is located at the eccentric wheel
With the outside of mounting plate；The movable axis 31 is plugged in the fixing axle, and one end is pierced by fixing axle close to the eccentric wheel
Port formed adjustable side 311, the other end be locking end 312；The guide rod is vertically fixedly installed on the eccentric wheel
End side surface and the side for being located at the adjustable side, the adjusting rod are vertically fixedly connected on the adjustable side and its end and set
It is equipped with pilot hole and is socketed on the guide rod 32 via the pilot hole；The periphery of the locking end is evenly arranged with several
Grafting tooth, fixing axle port inner wall corresponding with the locking end are provided with several inserting grooves 11, and the grafting tooth is inserted
It is connected in the inserting groove 11, grafting tooth, inserting groove are axially extending；The middle part variable diameter of movable axis forms step surface 314, and
Compressed spring, inner wall elastic connection of the movable axis via the compressed spring and the fixing axle, compression are set at step surface
The elastic force of spring pushes the movable axis towards the inserting groove direction；The locking lid 35 is threadingly attached to described solid
