Through the study of pressure, velocity, and the interaction between wheels and a wheel rail, study of the wheel rail (including wheels) and carrying capacity thereof and other problems is carried out. The device is simple in structure, and low in construction cost, and provides an ideal platform for the study of contact and mutual movement of wheels and the guide rail.
Description
Technical field
The present invention relates to the assistant experiment platform of wheel wheel load power, relate in particular to a kind of disc type wheel track testing table.
Background technology
The wheel track problem is one of emphasis problem of locomotive research always, particularly under the railway system, is more and more higher to the requirement of wheel track, and the travelling speed of locomotive is increasing, and load-carrying strengthens, and these all are the more requirement of having researched and proposed of wheel rail system.Laboratory study wheel track problem has theoretical research, true car research is arranged, certainly need study the wheel drive track parts, therefore it is very important designing a kind of wheel track testing table that can satisfy Laboratory Request, one can replace true car test, wheel track problem and the wheel rail contact problem of its two research locomotives that can be absorbed in.Be used at present the testing table of wheel track, be similar to true car simulated field mostly, like this since, testing table not only will possess the structure of enough bearing capacities, and takes up room greatly complex structure.
Summary of the invention
The object of the invention is to solve the shortcoming and defect of the existence of prior art, and a kind of disc type wheel track testing table of simple in structure, convenient test is provided.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of disc type wheel track testing table comprises the driving mechanism of base, dish type rail mechanism and dish type rail mechanism, and described driving mechanism is installed in the middle part of base, and the dish type rail mechanism places the top of driving mechanism.
Described driving mechanism comprises motor and control system thereof, and described dish type rail mechanism comprises guide rail, guide rail load bearing seat, ball, the ball load bearing seat that connects successively from top to bottom; The rotating shaft of this motor is connected with guide rail load bearing seat central point, and the ball load bearing seat is fixedlyed connected with base by support.
The rotating shaft of described motor can be connected with guide rail load bearing seat central point by flange; Described motor is installed in the middle part of base by motor base plate.
Compared with prior art, the present invention has following advantage and effect at least:
The present invention adopts the dish type track structure, has not only saved space problem but also overcome the problem of testing table bearing capacity, and wheel is placed on the guide rail, by the wheel pressue device wheel is pressurizeed, and motor drives the guide rail rotation, cooperates other instruments to finish experimentation.
The present invention can pass through research pressure, speed, and the interaction between wheel and the wheel track, studies problems such as wheel track (comprising wheel) and the power of carrying thereof.In addition, this disc type wheel track testing table can place in the closed chamber, carries out sealing test, with the operating modes such as gas of simulated field working environment, by matching with other instruments, obtains the situation of the reality motion of track and wheel.
The present invention is simple and easy to do, and is cheap, for the contact of research wheel track provides an ideal platform with moving mutually.
