Abstract
The utility model relates to a driving shaft assembly for an oil damper test stand, which is installed on a pedestal of the test stand and is connected with a driving system. The driving shaft assembly comprises a driving shaft, a first eccentric shoe arranged on the driving shaft, a driven shaft matched with the driving shaft, and a second eccentric shoe arranged between the driving shaft and the driven shaft. The driving shaft assembly is additionally provided with the driven shaft, the driving shaft and the driven shaft are both connected to a supporting seat through a bearing seat, and the second eccentric shoe is arranged between the driving shaft and the driven shaft, so that the force generated by a tested oil damper on the test stand is born by the driving shaft and the driven shaft together, resulting in good stressed state, low deformation liability and accurate test.
Description
Technical field
The utility model relates to a kind of testing equipment, the drive system in particularly a kind of testing equipment of testing rolling stock oil-pressure damper performance.
Background technology
Oil-pressure damper is one of critical component in the running mechanism of train part, riding quality and traffic safety to rolling stock have vital role, for the ease of further research to oil-pressure damper, the oil-pressure damper testing table has appearred, but, at present, the oil-pressure damper testing table of domestic use mostly adopts cantilever structure, and driving shaft only is provided with main drive shaft and eccentric shoe in forming; Can produce great impulsive force in the time of like this owing to testing table work, driving shaft is owing to only depend on main drive shaft to play the effect of supporting, thereby, deform easily, like this test oil pressure damper deflection the time, TT﹠C system also can cause the inaccurate of whole test result with the change calculations of driving shaft interior.
The utility model content
The purpose of this utility model be at existing oil pressure damper testing table driving shaft form built on the sand, yielding shortcoming, provide a kind of constitutionally stable driving shaft to form.
The technical solution of the utility model is: a kind of driving shaft of oil-pressure damper testing table is formed, be installed on the base of testing table, link to each other with drive system, comprise main drive shaft and the eccentric shoe that is arranged on the main drive shaft, described driving shaft also is provided with the driven shaft that matches with main drive shaft in forming, and is provided with eccentric shoe between main drive shaft and the driven shaft.
Preferably: on the described testing table base supporting seat is installed, main drive shaft and driven shaft are installed on the supporting seat by bearing seat.
Preferably: described eccentric shoe comprises and is installed on the guide way between main drive shaft and the driven shaft and is arranged at needle bearing and reinforcing sleeve on the guide way.
Preferably: described eccentric shoe is installed on main drive shaft and the driven shaft by adjusting leading screw.
Preferably: described drive system comprises frequency converter, motor, reductor, and wherein, reductor links to each other with main drive shaft.
The beneficial effects of the utility model are: driving shaft of the present utility model has been set up driven shaft in forming, main drive shaft all links to each other with supporting seat by bearing seat with driven shaft, eccentric shoe is arranged between main drive shaft and the driven shaft, the power of the tested oil-pressure damper generation of testing table work is born jointly by main drive shaft and driven shaft like this, stress is good, be difficult for producing distortion, test accurately.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model:
A kind of driving shaft of oil-pressure damper testing table is formed, be installed on the base 1 of testing table, link to each other with drive system, comprise main drive shaft 2 and the eccentric shoe 3 that is arranged on the main drive shaft 2, described driving shaft also is provided with the driven shaft 4 that matches with main drive shaft 2 in forming, and is provided with eccentric shoe 3 between main drive shaft 2 and the driven shaft 4.Supporting seat 5 is installed on the testing table base 1, and main drive shaft 2 and driven shaft 4 are installed on the supporting seat 5 by bearing seat 6.Eccentric shoe 3 comprises and is installed on the guide way 7 between main drive shaft 2 and the driven shaft 4 and is arranged at needle bearing 8 and reinforcing sleeve 9 on the guide way 7.Eccentric shoe 3 is installed on main drive shaft 2 and the driven shaft 4 by adjusting leading screw 10, can regulate the offset of eccentric shoe 3 by adjusting leading screw 10, thereby realize the test to dissimilar oil-pressure dampers.Drive system comprises frequency converter 11, motor 12, reductor 13, and wherein, reductor 13 links to each other with main drive shaft 2, and forming for driving shaft provides power.Tested vibration damper is formed 15 by gib head and is connected with testing table.
The testing table principle of work is the velocity amplitude that will measure to the industrial computer input by mouse or keyboard, speed setting value in the industrial computer sends frequency converter 11 to by the RS-485 serial line interface, and then control motor 12 turns round with correspondent frequency, motor 12 drives reductor 13, drive main drive shaft 2 rotations through the back of slowing down, on main drive shaft 2 and the driven shaft 4 eccentric shoe 3 is housed, eccentric shoe 3 drives motion slide block 14 and pumps, gib head linked to each other with motion slide block 14 under tested vibration damper passed through, thereby realized the skimulated motion of vibration damper.The velocity of rotation of motor 12 is regulated by control of conversion device 11 by computing machine, and stroke can be adjusted leading screw 10 by regulating, and then regulates the offset of eccentric shoe 3.
