Enclosed floating power measuring integrated device

Abstract

An enclosed floating power measuring integrated device relates to the power measuring technology. Supporting bearings and supporting covers are sequentially sleeved on small outer circles of flanges of bearing supports of a front end cover and a rear end cover of a special motor, a front supporting cover and a rear supporting cover are fastened at two ends of a supporting casing through bolts, and a rotation speed sensor is arranged in a threaded hole of the rear end cover. A boss lug A and a boss lug B are arranged in the middle of a squirrel cage base of the special motor and hoist one end of a tension compression sensor device and a static balancing device respectively, and a cooling fan and a top cover are arranged on the top of the supporting casing and fastened with the supporting casing through screws respectively. An extending end of a rear shaft of the special motor is connected with a coupler. The enclosed floating power measuring integrated device has the advantage of being compact in structure, high in response speed, measuring accuracy and reliability, small in vibration and noise, convenient to use and maintain, long in service life and the like.

Description

technical field [0001] The invention relates to dynamometer technology, in particular to a closed floating dynamometer integrated device of a motor and dynamometer equipment. Background technique [0002] The existing horizontal dynamometer adopts a direct-connected torque sensor, and two sets of elastic couplings are used to connect the shaft extensions at both ends of the torque sensor with the shaft extension of the special motor and the shaft extension of the machine under test respectively, and horizontally Install it on a specific installation base plate, and adjust the center height and coaxiality accurately. The adjustment error should be determined according to the speed of the dynamometer device, and should generally be controlled at ≤0.06mm. After proper adjustment, fasten it to the installation with bolts. No loosening is allowed on the bottom plate. Finally, connect the power terminals of the special motor and the torque sensor with the control system. When the...

AI Technical Summary

Problems solved by technology

The device occupies a large area and is difficult to install and debug. Especially for the dynamometer with a speed of more than 10,000r / min, the accuracy of debugging is high, and repeated debugging is required to achieve the best results. The debugging process is quite complicated. If the center height cannot be guaranteed and coaxiality, the device will experience large vibrations, resulting in measurement errors and damage to special motor bearings and sensors

[0005] 2. The structure is complex, the volume is large, the vibration is large, the noise is large, and the installation and debugging process of the overall device is complex

[0006] 3. Due to the weak ability of the direct-connected sensor to withstand axial force, bending force, torsion force, lateral force, and bias force, the measurement error of the device is relatively large, and it is easy to cause damage to the sensor;

[0007] 4. The running speed is limited, basically it can only be used below 2000r / min
