Abstract
The utility model discloses a transmission detection device of an electric actuating mechanism, which comprises a worm shaft and a motor shaft, wherein the input end of the worm shaft is provided with the motor shaft; and the transmission detection device is characterized in that a sensor is arranged around the motor shaft. The transmission detection device of the electric actuating mechanism directly detects the motor shaft, namely a high speed shaft, can improve the detection precision of a complete machine under the condition that the precision of the sensor is definite, and also can detect speed characteristics of a motor; the motor speed is in a nonlinear relationship with the force moment, therefore, one sensor can realize two functions of position detection and force moment detection.
Description
Technical field
The utility model relates to electric operator, specifically is a kind of transmission pick-up unit of electric operator.
Background technology
Electric operator is used for process automation control, and its transmission mainly by worm and gear, needs the position and the moment of output shaft are detected in operational process.Generally, position transducer can directly detect the output shaft of low speed, but precision is lower, also needs a torque sensor could realize that moment detects in addition.
The utility model content
The utility model provides a kind of transmission pick-up unit of electric operator, solve the low problem of position transducer accuracy of detection, and will substitute the function of two sensors with a sensor.
The transmission pick-up unit of electric operator of the present utility model comprises worm shaft and motor shaft, and the input end of worm shaft is a motor shaft, it is characterized in that: be provided with a sensor around motor shaft.
It is high speed shaft that the transmission pick-up unit of this electric operator that the utility model provides directly detects motor shaft, can improve the accuracy of detection of complete machine under the certain situation of sensor accuracy.Simultaneously, can detect the velocity characteristic of motor, motor speed and moment exist nonlinear relationship, therefore can realize two functions that position probing and moment detect with a sensor.
Description of drawings
Accompanying drawing is the structural representation of the utility model electric operator transmission pick-up unit.
1. worm shafts among the figure, 2. motor shaft, 3. sensor.
Embodiment
The transmission pick-up unit of this electric operator of the present utility model comprises worm shaft 1 and motor shaft 2, and the input end of worm shaft 1 is a motor shaft 2, is provided with a sensor 3 around motor shaft 2.It is motor shaft 2 that sensor 3 detects high speed shaft, and therefore under the certain situation of sensor 3 precision, the complete machine precision can be accomplished very high.In addition, because sensor 3 directly detects motor shaft 2, therefore can detect the velocity characteristic of motor, motor speed and moment exist nonlinear relationship, realized with sensor 3 detection positions and moment, thereby simplified the structure of product, improved the stability of product.
