Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The gearing that integrated torque detects, structure as shown in Figure 1, comprising: power unit, gear unit, bearing unit and detecting unit;
Power unit comprises motor 1 and speed reduction unit 2;
Gear unit comprises cone tooth transmission 3, transmission shaft 5 and square shaft 8;
Bearing unit comprises motor fixing plate 4, square shaft fixed head 11, transmission shaft fixed head 12 and clutch shaft bearing 6, second bearing 9;
Detecting unit comprises the first film pressure transducer 7, second diaphragm pressure sensor 10, is installed on homonymy above square shaft 8, can detect the pressure of positive and negative both direction simultaneously.
Motor 1 and speed reduction unit 2 are bolted fixing by the mounting hole of speed reduction unit 2 front end and motor fixing plate 4; Motor fixing plate 4 and transmission shaft fixed head 12 are bolted, and transmission shaft fixed head 12 is connected with transmission shaft 5 with the second bearing 9 by clutch shaft bearing 6; Motor 1 is connected with transmission shaft 5 by cone tooth transmission 3 with speed reduction unit 2 output shaft; Square shaft 8 is parts of transmission shaft 5; The first film pressure transducer 7, second diaphragm pressure sensor 10 is installed in the minim gap above square shaft 8 in both sides and square shaft fixed head 11, and formation closely cooperates.Square shaft 8 is connected with square shaft fixed head 11 by the first film pressure transducer 7, second diaphragm pressure sensor 10; Square shaft fixed head 11 external load.
Motor 1, speed reduction unit 2, motor fixing plate 4, transmission shaft fixed head 12 are static element; When motor 1 works, transmission shaft 5, square shaft 8 and square shaft fixed head 11 rotate centered by transmission shaft 5 axial line.
The reacting force that the operation torque of external load is acted on square shaft fixed head 11 by detection side's oblique crank Z 8 obtains.In the course of work, square shaft fixed head 11 can result from the contrary movement tendency of load sense of rotation, the moment of the sizes such as same generation and opposite direction, and extrude one of them diaphragm pressure sensor (as the first film pressure transducer 7), the size of the moment of reaction can be obtained by the product of pressure and the arm of force, and then draw the size of motor 1 output torque; In like manner, when load rotates toward another one direction, square shaft fixed head 11 can extrude another one diaphragm pressure sensor (as the second diaphragm pressure sensor 10), and draws the size of motor output torque.
The one-piece construction of moment inspecting module is very dexterous compact, does not affect structure and the installation of former running part.When using gearing of the present utility model to carry out the measurement of motor output torque, first motor 1 and speed reduction unit 2 are placed on motor fixing plate 4 fixing by user, are connected with transmission shaft 5 by cone tooth transmission 3.And the first film pressure transducer 7, second diaphragm pressure sensor 10 is positioned over both sides, square shaft fixed head 11 side respectively.Starter motor 1, square shaft fixed head 11, by load reactive forces square, one in extrusion film pressure transducer, can be obtained the size of the moment of reaction, and then draw the size of loaded work piece moment by the product of pressure and the arm of force; In like manner, when load rotates toward another one direction, square shaft fixed head can extrude another one diaphragm pressure sensor, draws the size of loaded work piece moment.
