Abstract
The present invention relates to a torque spring loader of a test bench for a space harmonic gear reducer. The present invention comprises a drive electric machine, a test harmonic gear reducer connected with an output end of the drive electric machine and a torque spring connected with the drive electric machine by a test accompaniment harmonic gear reducer, wherein the output end of the test harmonic gear reducer is connected with the output end of the torque spring by a synchronous wheel group. Certain rotary angle difference exists between output shafts of the test harmonic gear reducer and the test accompaniment harmonic gear reducer by the drive electric machine and the torque spring. Consequently, the torque spring rotates following the two shafts in a low-speed way and simultaneously produces the elastic deformation under the action of the rotary angle difference. Moreover, the torque difference produced between the two harmonic gear reducers can provide load for the tested reducer.
Description
Technical field
The invention belongs to the synchronous deceleration loading device of mechanical type, particularly a kind of space harmonics gear reducer test stand torsion spring loader.
Background technique
In order to test the slowly various performances of the harmonic gear reducer of rotation of light barrier on the driving man-made satellite that uses, solar cell, antenna in space environment, people have built space harmonics gear reducer test stand.This test stand needs and can move in atmosphere, vacuum and hot vacuum environment, and its serviceability temperature scope is-80 ℃-75 ℃.For the situation of slowly rotating at laboratory simulation man-made satellite light barrier, battery, antenna, test stand need load under low-speed running.At present, load commonly used both at home and abroad has electronic synchronous loader, magnetic powder brake, magnetic hysteresis power measurer, electric eddy current dynamometer, hydrodynamometer, hydraulic pressure loading device, electric dynamometer etc. with suction merit equipment.Its performance characteristics, application area have nothing in common with each other, and wherein have only magnetic powder brake to be applicable to slow-speed of revolution occasion.The magnetic powder brake that original design adopts low speed to load, but since in a vacuum iron powder cold welding can take place, make the magnetic powder brake cisco unity malfunction.Therefore, invention is a kind of can be used for vacuum environment and can realize that the device of low speed loading is very necessary.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, flexible and convenient operation can realize accurate two-way loading under the low speed, and pine is carried voluntarily, and the reliability height is applicable to the space harmonics gear reducer test stand torsion spring loader of vacuum and low temperature environment.
For achieving the above object, the technical solution used in the present invention is: comprise the harmonic gear reducer that first drive motor is connected with output terminal with first drive motor, it also comprises second drive motor and tries the torsion spring that harmonic gear reducer is connected with second drive motor by accompanying that the output terminal of test harmonic gear reducer is connected by synchronous train with the output terminal of torsion spring.
Another characteristics of the present invention are: torsion spring is that two ends offer slit and the middle cylindrical structure that is evenly distributed with equally spaced spring sheet.
The present invention is by test harmonic gear reducer and the circulation train of accompanying examination harmonic gear reducer and torsion spring to form, make the test harmonic gear reducer and accompany the output shaft of examination harmonic gear reducer to have certain outer corner difference by two drive motor and a torsion spring, make torsion spring in the diaxon low speed rotation, under the outer corner difference effect, resiliently deformable takes place, and the generation torque differences comes to provide load for the test retarder between two harmonic gear reducers.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention;
Fig. 2 is the structural representation of torsion spring 6 of the present invention.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and working principle are described in further detail.
Referring to Fig. 1, the present invention includes the harmonic gear reducer 3 that first drive motor 1 is connected with output terminal with first drive motor 1, it also comprises second drive motor 8 and tries the torsion spring 6 that harmonic gear reducer 7 is connected with second drive motor 8 by accompanying that the output terminal of test harmonic gear reducer 3 is connected by synchronous train 5 with the output terminal of torsion spring 6.The input torque dynamic force moment sensor 2 that is used to measure harmonic gear reducer 3 is installed at first drive motor 1 and test between the harmonic gear reducer 3, is equipped with at the output terminal of harmonic gear reducer 3 and is used to measure the output speed of harmonic assembly and torque, the measurement of rotating speed sensor 4 of output torque.Under different loads, by the signal process conditioning circuit that sensor comes out, send into computer data acquiring and processing system, through handling and computing, just can obtain required measured value.
Referring to Fig. 2, torsion spring 6 of the present invention offers slit 9 and the middle cylindrical structure that is evenly distributed with equally spaced spring sheet 10 for two ends.
The present invention in use only needs two drive motor 1 of control and 8, makes to accompany examination harmonic gear reducer 7 to have identical input speed with test harmonic gear reducer 3, but does not start simultaneously.Then just there are certain outer corner difference in two harmonic gear reducers 3 and 7 output terminal, and their output shaft rotates under identical rotating speed with certain outer corner difference.Certain elastic deformation takes place in torsion spring 6 under the outer corner difference effect, makes its two ends produce torque differences, thereby provides load for testing retarder.The effect of train 5 synchronously is that the rotating speed of test harmonic gear reducer output and transmission of torque are tried on the axle of harmonic gear reducer place to accompanying.The size and Orientation of the output terminal outer corner difference of two harmonic gear reducers of control, just can access different loading effects: outer corner difference is big more, and the load that is added in the test harmonic gear reducer is just big more; Adjust the direction of outer corner difference, just can realize the loading of positive and negative both direction.In loading procedure, test and accompany examination harmonic gear reducer 3 and 7 input speed and the phase difference between them to provide by drive motor.
