Summary of the invention
The purpose of this utility model is to propose a kind of linear electric motors to-and-fro movement constant load proving installation for carrying out the defects such as varying duty test and low precision in can only one way measuring of overcoming that above-mentioned prior art exists, experimentation.
The technical solution adopted in the utility model is: linear electric motors comprise linear motor rotor and linear motor stator electric and are located on test platform upper surface, the outside at linear motor stator electric two ends is respectively provided with fixed pulley, the below of test platform is provided with magnetic powder brake, the output shaft of magnetic powder brake is fixedly connected with line and rolls, line rolls and on outer ring, is provided with vertically two grooves, transmission rope is fixedly connected with first groove that linear motor rotor one end and line roll on and on the fixed pulley of one end, second groove that another root transmission rope is fixedly connected with that the linear motor rotor other end and line roll on and on the fixed pulley of the other end, on two grooves, be all wound with the transmission rope of certain length, the winding direction of the transmission rope on two grooves is contrary, manually tension controller provides direct supply to magnetic powder brake.
The utility model has the following advantages after adopting technique scheme:
1, the utility model is applicable to the test of linear electric motors to-and-fro movement constant load, simple in structure, precision is high.
2, the transmission rope between magnetic powder brake and linear motor rotor adopts wire rope to connect, and because wire rope is not easy to occur elastic deformation, thereby has improved the precision of experiment.
