A torque sensor assembly 13 is arranged between the left and the right lower chuck bodies 8'; an elastic sensitive body 19, a housing body 29, a supporting arm 28 and a pulling plate 23 are arranged in the sensor assembly 13. The utility model has the advantages of compact structure, small size, light weight, portability, high testing precision and sensitivity, and easy installation. The utility model is suitable for ships with different sizes, and non-marine dynamic force machines.
Description
The utility model relates to a kind of can the test moment of torsion, power and the rotating speed of diesel engine, motor, water pump, blower fan, oil pump, automobile, engineering machinery etc., especially can be at the sensing device that carries out shiphoard measurement with output torque, power, the rotating speed of boat diesel engine.
China is used for shiphoard measurements such as boat diesel engine moment of torsion at present and mainly contains the string wire dynamometer.The sensor that this dynamometer adopts is two string wires that are installed on the chuck.There is following defective in this dynamometer: 1, complex structure, and volume is big, and Heavy Weight carries inconvenience; 2, string wire rapid wear ring, measuring accuracy is low; 3, can't accomplish that the various diameters of axle are general; 4, difficulty is installed, owing to can not realize remote measurement, must adopts the collector ring transmission signals, cause disturbing big, measuring accuracy is low, and the installation of collector ring support also must electric welding, takes a lot of work when making the mounting cost of sensor; 5 volumes are big, and chuck, collector ring are installed on the axle, occupy the bigger locational space of transmission shaft, and the middle craft that makes some not possess this position can't use.In the torsion-testing of non-power machine peculiar to vessel (as motor, blower fan, water pump etc.), the overwhelming majority is to adopt plug-type sensor at present, and this almost is impossible for on-the-spot test.
The purpose of this utility model is to overcome the existing dynamometer existing defective of sensor, a kind of compact conformation is provided, volume is little, highly sensitive, the measuring accuracy height, easy to carry, the various diameters of axle can be general, installs easily, disturb little, the sensing device of the test output shaft torque that big craft and non-power machine peculiar to vessel all can be suitable for.
Task of the present utility model realizes in the following manner: this is used to test the sensing device of power machine output shaft torque, comprise chuck body, torque sensor, support arm and housing, comprise two chuck bodies in the device, chuck body is by the upper chuck body, the lower chuck body passes through swing bolt, nut, pin and register pin are formed by connecting, be provided with the V-arrangement slide block in the upper chuck body, V-arrangement slide block below is provided with pressing, V-arrangement slide block top is provided with clamping screw, magnetic steel sleeve and magnet steel, be provided with cushion block in the lower chuck body, be provided with the torque sensor assembly by screw and tommy between the lower chuck body of the left and right sides, the lower-left chuck body passes through register pin, parallel beam type elasticity sensitive body in socket head cap screw and the sensor unit connects, the elasticity sensitive body is connected with sensor housing by screw, housing is provided with support arm outward, the support arm left end is equipped with arm-tie by screw and pin, the support arm right-hand member is connected with the bottom right chuck body, and support arm is provided with screw rod and nut, and the housing right-hand member is equipped with gland by screw.
The utility model is compared with sensor with existing dynamometer, compact conformation, and volume is little, and is in light weight, easy to carry, disturb little measuring accuracy and highly sensitive, the various diameters of axle all can be general, install easily, the time and labour saving, big craft and non-power machine peculiar to vessel all can be suitable for.
Concrete structure of the present utility model is provided by drawings and Examples.
Fig. 1 is a structural representation of the present utility model; (being unkitted sensor unit 13)
Fig. 2 has increased the view of sensor unit 13 for the transverse section of Fig. 1;
Fig. 3 is the structural representation of sensor unit 13.
Embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3, this is used to test the sensing device of power machine output shaft torque, two chuck bodies about comprising, chuck body is by upper chuck body 8, lower chuck body 8 ' is by swing bolt 1, nut 2, pin 3 and register pin 4 are formed by connecting, V-arrangement slide block 5 is housed in the upper chuck body 8, V-arrangement slide block 5 belows are installed with pressing 7, clamping screw 17 is equipped with in V-arrangement slide block 5 tops, magnetic steel sleeve 15 and magnet steel 16, clamping screw 17 can drive V-type slide block 5 and move up and down, be fixed with cushion block 9 by screw 6 in the lower chuck body 8 ', chuck body is pressed on the measured axis 18 tightly, by screw 10 sample piece 11 is housed between the left and right sides upper chuck body 8, by screw 12 and tommy 14 torque sensor assembly 13 is housed between the left and right sides lower chuck body 8 ', lower-left chuck body 8 ' is by register pin 21, parallel beam type elasticity sensitive body 19 in socket head cap screw 20 and the sensor unit 13 connects, elasticity sensitive body 19 is connected with sensor housing 29 by screw 24, the housing 29 outer support arms 28 that are provided with, support arm 28 left ends are equipped with arm-tie 23 by screw 22 and pin 26, support arm 28 right-hand members are connected with bottom right chuck body 8 ', have two screw rods 27 and nut 25 on the support arm 28, housing 29 right-hand members are equipped with gland 31 by screw 30.
After the utility model treated that chuck clamps, sample piece 11 can be taken away, and on the position of sample piece 11, frequency modulation transmitter was installed.Cushion block 9 makes chuck be with measured axis 18 at 3 with pressure nail 7 and contacts, to improve measuring accuracy.The magnet steel 16 that is installed on the upper chuck body 8 sends tach signal along with the rotation of measured axis 18 and chuck.The space at housing 29 rear portions in the sensor unit 13 is used for installing amplification, voltage-frequency change-over circuit plate and battery, when measured axis 18 is subjected to torsional interaction, left and right sides chuck promptly produces a relative angular displacement, adjusting screw(rod) 27 withstands elastic body 19, make elastic body 19 produce flexural deformation, and will export a voltage signal that becomes corresponding relation with torque by the electric bridge that the foil gauge that is attached on the elastic body 19 is formed, make voltage signal through shaping, launch by transmitter, receive by receiver again, the input secondary instrument shows or prints moment of torsion or performance number.
