Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
Please refer to Fig. 1 deformation-sensing gear of the present invention embodiment's floor map.Deformation-sensing gear 10 of the present invention is by an axle collar 11, a gear ring 12, and several spokes 14 formations that connect the axle collar 11 and gear ring 12.The material of gear 10 can be that the preferable materials of rigidity such as metal, engineering plastics are made.
The axle collar 11 is provided with an axis hole 15, and a side of axis hole 15 is provided with a keyway 16.
Please be simultaneously with reference to Fig. 2, A-A direction sectional view for Fig. 1 of the present invention, the bi-side of the axle collar 11 respectively are provided with a conductive hoop 30, conductive hoop 30 the bests are made by metals such as copper, can post at the axle collar 11 outer surfaces, or be located at the deep gouge of the axle collar 11 as shown in Figure 2, make the outer surface of conductive hoop 30 concordant with the axle collar 11 outer surfaces.Each electrically connects with a lead 40 between strain gauge 20 and two conductive hoops 30.Therefore, when producing torque and cause spoke 14 distortion because of external force between the axle collar 11 of gear 10 and the gear ring 12, the strain gauge 20 that adheres on spoke 14 is also along with spoke 14 produces distortion (please read Fig. 4), and the resistance change before and after strain gauge 20 distortion can link the Detecting device measurement by conductive hoop 30 and obtain numerical value.
Please refer to the schematic representation that Fig. 3 deformation-sensing gear of the present invention connects rotating shaft and brush, on using, when gear 10 of the present invention is set up on the machinery as power transmitting assembly, gear 10 is fixed on a rotating shaft 50 by axis hole 15, and rotating shaft 50 and gear 10 are rotated with portion by keyway 16 ccontaining key pieces (not illustrating), at the conductive hoop 30 of the axle collar 11 both sides of gear 10 electrical contact one brush 60 respectively, brush 60 is electrically connect to a detecting instrument (not illustrating) again, and set amount of deformation at detecting instrument, so, when gear 10 engaging gears adjacent with other take place unusually when transmitting spoke 14 amount of deformation that cause gear 10 and surpass setting value, promptly can detect and give a warning by detecting instrument.
Comprehensive above-mentioned character express also in conjunction with the accompanying drawings as can be seen, the present invention adheres on strain gauge the spoke outer surface of gear, the amount of deformation when but unusual torque takes place measuring gear, and with signal output for the detecting instrument detecting, before the gear teeth crumble, be able to strain and take precautions against.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
