Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
See Fig. 1, the Power Drive Unit that integrated torque of the present utility model detects, comprises power unit, gear unit, bearing unit and detecting unit;
Power unit comprises motor 3 and speed reduction unit 4;
Gear unit comprises cone tooth transmission 6, transmission shaft 7 and square shaft 9;
Bearing unit comprises supporting base 1, square shaft fixed head 2, motor fixing plate 5, transmission shaft fixed head 8 and bearing 10;
Detecting unit comprises the first film pressure transducer 11, second diaphragm pressure sensor 12, is installed on square shaft 9 side homonymy, can detects the pressure of positive and negative both direction simultaneously.
Motor 3 and speed reduction unit 4 are bolted fixing by the mounting hole of speed reduction unit 4 front end and motor fixing plate 5; Motor fixing plate 5 and transmission shaft fixed head 8 are bolted, and are connected with transmission shaft 7 by bearing 10; Transmission shaft fixed head 8 external load; Motor 3 is connected with transmission shaft 7 by cone tooth transmission 6 with speed reduction unit 4 output shaft; Square shaft 9 is parts of transmission shaft 7; The first film pressure transducer 11, second diaphragm pressure sensor 12 is installed in the minim gap in both sides, square shaft 9 side and square shaft fixed head 2, and formation closely cooperates.
Supporting base 1 and square shaft fixed head 2 are static element, and transmission shaft 7 and square shaft 9 are connected with square shaft fixed head 2 by the first film pressure transducer 11, second diaphragm pressure sensor 12, and only have minute movement, square shaft fixed head 2 is connected with supporting base 1; When motor 3 works, motor 3, speed reduction unit 4, motor fixing plate 5, transmission shaft fixed head 8 rotate centered by transmission shaft 7 axial line.
The reacting force that the operation torque of external load is acted on square shaft holder 2 by detection side's oblique crank Z 9 obtains.In the course of work, square shaft fixed head 2 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 11), 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 3 output torque; In like manner, when load rotates toward another one direction, square shaft fixed head 2 can extrude another one diaphragm pressure sensor (as the second diaphragm pressure sensor 12), and draws the size of motor 3 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 the Power Drive Unit using this integrated torque to detect carries out the measurement of motor output torque, first motor 3 and speed reduction unit 4 are placed on motor fixing plate 5 fixing by user, are connected with transmission shaft 7 by cone tooth transmission 6.And the first film pressure transducer 11, second diaphragm pressure sensor 12 is positioned over both sides, square shaft fixed head 2 side respectively.Starter motor 3, square shaft fixed head 2, 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, and draws the size of loaded work piece moment.
