Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Number in the figure: 1 displacement sensor rod; 2 displacement transducers; 3 contact roller slide plates; 4 contact rollers; 5 contact roller mount pads; 6 pull bars; 7 cylinders; 8 base plates, 9 line slideways; 10 connecting rods.
Embodiment
See Fig. 1, be applied in the present embodiment main detected by backlash in the version of contact roller modified gear be: bottom contact roller 4 being fixedly mounted contact roller slide plate 3, contact roller slide plate 3 is slidably matched with the line slideway 9 vertically arranged, contact roller slide plate 3 is driven can be moved up and down in line slideway 9 by cylinder 7, and line slideway 9 is fixedly installed on base plate 8.
As shown in Figure 1, on base plate 8, the side being positioned at line slideway 9 is fixedly installed displacement transducer 2, and the displacement sensor rod 1 in displacement transducer 2 is parallel to each other with line slideway 9; Displacement sensor rod 1 is connected firmly by connecting rod 10 and contact roller slide plate 3, displacement sensor rod 1 is formed by connecting rod 10 and contact roller slide plate 3 and links.
In concrete enforcement, corresponding vibrational power flow also comprises:
On base plate 8, the opposite side being positioned at line slideway 9 is fixedly installed cylinder 7, and the piston rod in cylinder 7 is connected firmly by pull bar 6 and contact roller slide plate 3, and the piston rod in cylinder 7 and line slideway 9 are parallel to each other.
The range arranging displacement sensor rod 1 is not less than the stroke of cylinder 7.
Be fixedly installed contact roller mount pad 5 in the bottom of contact roller slide plate 3, the wheel shaft of contact roller 4 is bearing in contact roller mount pad 5 by bearing, keeps contact roller 4 automatically can rotate in contact roller mount pad 5.
The present embodiment utilizes displacement transducer 2 to detect putting in place by the contact roller 4 of air cylinder driven, being detected by tooth of compatible multi items different-diameter.Whether promote contact roller slide plate 3 by the piston rod in cylinder 7 by pull bar 6 to move down, make contact roller 4 be pressed on main reducing gear by tooth, detected simultaneously put in place by displacement transducer 2, its process is simple, reliable and accurate, can adapt to the main reducing gear of different model.
