Further, described torque sensor is connected by being with the shaft coupling power transmission of seam with described drive motor, the first driving shaft respectively.
Further, between described first driving shaft and differential mechanism to be tested, be provided with certain cardiac skeleton, this centering frame upper has a circular hole, is equipped with the ball bearing matched with described first driving shaft in circular hole.
Further, described drive motor is variable-frequency motor.
The beneficial effects of the utility model: bringing onto load that drive motor, torque sensor achieve differential mechanism rotates and differential motion to utilize magnetic powder brake to arrange in pairs or groups, simplify traditional long duration test scheme, simple and light, easy-to-operate, with low cost, improve work efficiency, and can be common in the long duration test of other rotary part.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is three-dimensional structure diagram of the present utility model.
Embodiment
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of as described in Figure 1 for the simple and easy long duration test compound table of automobile differential, it includes drive motor 1, for the differential mechanism fixed mount 8 of positioning supports differential mechanism 7 to be tested, and described drive motor 1 carries out torque sensor 2, first driving shaft 5 of power transmission successively to described differential mechanism 7 to be tested; Magnetic powder brake 10 is connected with as load respectively by the second driving shaft 9 at described differential mechanism 7 two ends to be tested.
The utility model is directly braked with magnetic powder brake 10 or is provided load torque, drives rotate with drive motor 1, and the bringing onto load realizing differential mechanism rotates and differential motion, simplify traditional long duration test scheme, simple and light, easy-to-operate, with low cost, improve work efficiency.
Particularly, sensor support base 4 is fixed with bottom described torque sensor 2, brake support 11 is fixed with bottom described magnetic powder brake 10, this sensor support base 4, brake support 11 and differential mechanism fixed mount 8 make the power transmission of described drive motor 1, torque sensor 2, first driving shaft 5, second driving shaft 9 and magnetic powder brake 10 be in same level, to ensure the steady of whole kinematic train, improve test mass.
Further, described torque sensor 2 is connected by being with the shaft coupling power transmission of seam with described drive motor 1, first driving shaft 5 respectively, also the frock etc. that band seam connects can be adopted, testing equipment sharp pounding and then infringement equipment and differential mechanism to be tested 7 is caused to avoid the transmission when running up between drive motor 1 to differential mechanism 7 to be tested input there will be beating, and the safety of hazard test personnel.
Certain cardiac skeleton 6 is provided with between described first driving shaft 5 and differential mechanism to be tested 7, this centering support 6 top has a circular hole, be equipped with the ball bearing matched with described first driving shaft 5 in circular hole, coordinate each link to play positioning action, thus reduce the eccentric motion in rotating.
During use, drive motor 1 is adopted variable-frequency motor, the central shaft being rotarily driven torque sensor 2 by adjustment drive motor 1 is rotated, and is then rotarily driven by the first driving shaft 5, thus drives the running of differential mechanism 7 to be tested, realize the rotation of the second driving shaft 9; The sense of rotation of drive motor 1 and rotating speed regulate by the frequency converter of this drive motor 1, and differential mechanism 7 to be tested load regulates realization by magnetic powder brake 10, and the principle of work for magnetic powder brake 10 belongs to prior art, does not repeat at this.
When the load that both sides magnetic powder brake 10 provides is the same, just achieve being synchronized with the movement of differential mechanism 7 two ends to be tested, when magnetic powder brake 10 moment of torsion is comparatively large, when stoping the second driving shaft 9 of homonymy to rotate, just achieve differential motion.
Whole testing equipment is installed light, simple to operate, with low cost, work efficiency and reliability is improve while simplifying testing equipment, but also the long duration test of other rotary part or product can be applied to, use variation, make original cost reduce about 2/3.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, embodiment and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
