Abstract
The utility model discloses a flexibly-connected engine torque detecting device, which comprises a load, wherein the load is connected with an engine power output shaft through a coupling device which is a flexible shaft. The engine power output shaft and the load in the engine torque detecting device are connected by the flexible shaft, the flexible shaft has the advantages of convenient connection, small mounting space, large rotary speed range, continuous and stable rotary speed, low abrasion, long service life and low noise, therefore, the problem of coaxiality can be overcome in the process of installation, and the accuracy of the detected results can be guaranteed, meanwhile, the connection process of the engine output shaft and the load can be greatly simplified, the connection efficiency before detection can be improved, and the working efficiency of the torque detection can be guaranteed during the production and maintenance of engines.
Description
Technical field
The utility model relates to a kind of engine performance pick-up unit, particularly a kind of engine torque master that flexibly connects.
Background technology
Torque is the more important performance index of engine such as engine, therefore must detect when producing and keep in repair.Conventional detection generally uses the magnetic powder brake even load to connect the powered maneuver power output shaft, in braking procedure, mechanical signal is transformed into electric signal output by magnetic powder brake, whole process utilizes magnetic powder brake to have exciting curent and the linear substantially characteristics of transmitting torque, obtains torque data.Have advantages such as response speed is fast, simple in structure, pollution-free, noiselessness, no impact shock, energy savings.
In the prior art, in measuring the torque process, magnetic powder brake connects engine power output shaft by hitch bar, and the hitch bar of use is hard connection.This hard syndeton transmission is reliable, but the right alignment that connects is had relatively high expectations, if having coaxiality error during assembling, then eccentric rotary can occur, thereby bear moment of flexure, makes the torque error that records bigger.Thereby, in connection procedure, need to guarantee right alignment, give the installation of equipment and fixedly bring very big trouble.
Therefore, need improve, guarantee the accuracy of testing result, simultaneously, can improve the attended operation efficient before detecting greatly the motor torque pick-up unit.
The utility model content
In view of this, the purpose of this utility model provides a kind of engine torque master that flexibly connects, and guarantees the accuracy of testing result, simultaneously, can simplify the connection procedure of powered maneuver power output shaft and magnetic powder brake greatly, improve the attended operation efficient before detecting.
The engine torque master that flexibly connects of the present utility model comprises load, and described load connects the powered maneuver power output shaft by hitch bar, and described hitch bar is a flexible axle.
Further, the axle core two ends of described flexible axle are connected with the load socket joint with the powered maneuver power output shaft respectively;
Further, described powered maneuver power output shaft is connected with the axle core of flexible axle by the shaft coupling pipe nipple, and described shaft coupling pipe nipple one end is fixedlyed connected on circumference with the powered maneuver power output shaft, and the other end is provided with the axle core socket joint hole of flexible axle;
Further, the female part at the axle core two ends of described flexible axle with the xsect of its axis normal on be square, the socket joint hole in shaft coupling pipe nipple and the load with the xsect of its axis normal on also be square;
Further, described load is a magnetic powder brake.
The beneficial effects of the utility model are: motor torque pick-up unit of the present utility model, the powered maneuver power output shaft adopts flexible axle to be connected with load, flexible axle has easy to connect, installing space is little, the range of speeds is wide, rotating speed is continual and steady, low wearing and tearing, long-life and low noise advantages, need not consider the right alignment problem in the installation process, and can guarantee the accuracy of testing result, simultaneously, can simplify the connection procedure of powered maneuver power output shaft and load greatly, attended operation efficient before improve detecting is when guaranteeing engine production and the work efficiency that torque detects during maintenance.
