Description
Technical field
The utility model belongs to the torque measurement technical field, is a kind of moment of torsion rapid measurement device of shovel loader transmission shaft specifically.
Background technology
The shovel loader transmission shaft is the important component part of shovel loader power train, and its two ends have cross coupler and flange, and front end flange utilizes bolt to be connected with the output shaft of gear-box flange, and back end flanges utilizes bolt to be connected with drive axle input shaft flange.
In the gatherer process of shovel loader transmission system load spectrum, the torque signal of measuring transmission shaft is groundwork, owing to carry out the measurement of the shovel loader torque transmission shaft signal under different type of machines, the multiple industrial and mineral, thereby collection period is long, the cost costliness.
The more employing strain of the torque measurement of shovel loader transmission shaft chip torque measuring method in the prior art, promptly earlier transmission shaft to be measured is disassembled from the shovel loader power train, after its surface carried out careful polishing, cleaning treatment, to the paster fixing and waterproof and dampproof processing that waits that bonds, also to demarcate afterwards strain-gauge transducer, to demarcate the good transmission shaft to be measured that strain-gauge transducer is housed at last and be installed in the shovel loader power train, carry out torque measurement.This method often needs the moment of torsion rating test platform to the transmission shaft design specialized of different size in calibration process, make that measuring period is long, precision is not high, and the change and the destruction that cause the structure and the intensity of transmission shaft to be measured easily.
Chinese patent instructions CN94230558.2 discloses a kind of torque transmission shaft sensor, and its structure is the following positioning body that is, is the seize jig above, the middle connection is the seize card, the floating arm beam is housed above, and two ends are floating arm beam card, and the centre is a measured axis, wherein a floating arm beam is a longitudinal opening, another is a transverse opening, and the two sides is added with thimble, the one, and point-to-point, another is face-to-face, on the floating arm beam foil gauge is housed.This device is contained in foil gauge in the floating overarm, but not on the measured axis, thereby avoided to a certain extent measured axis is carried out the plenty of time that surface treatment spent, but, this device connects with bolted by both sides seize card, be difficult to guarantee the compactedness that connects, will cause the inconsistent of suffered moment of torsion and the suffered moment of torsion of measured axis on the sensor, thereby reduced the accuracy of torque measurement.In addition, in case the arc radius of this device seize card is determined, just can only carry out torque measurement to the unique transmission shaft of diameter, can not utilize same device that a series of transmission shafts of different radii are carried out torque measurement, and need design corresponding rating test platform at different measured axises, cause measuring period longer.
Therefore, develop and a kind ofly can realize that same device is applicable to the moment of torsion rapid measurement device of different size (different-diameter, different length) shovel loader transmission shaft, become that shovel loader transmission system load spectrum is gathered and the active demand of work such as further development research, test analysis and quality inspection.
