Abstract
The utility model discloses a hollow output shaft of an electric eddy current dynamometer, belongs to the field of eddy loading equipment and aims at solving a problem that an electric eddy current dynamometer with a solid output shaft can not realize simultaneous loading on two output shafts of a concentric double-shaft output motor. The hollow output shaft comprises a hollow inner shaft output assembly connected with an inner shaft of the concentric double-shaft output motor and a hollow outer shaft output assembly connected with an outer shaft of the concentric double-shaft motor, and the hollow inner shaft output assembly and the hollow outer shaft output assembly are in the same axis. The hollow output shaft of the electric eddy current dynamometer meets requirements of testing loading of the concentric double-shaft output motor and provides reliable testing loading equipment for the concentric double-shaft motor.
Description
Technical field
The utility model relates to eddy current loading equipemtn field, is specially a kind of hollow output shaft of electric eddy current dynamometer.
Background technique
Existing electric eddy current dynamometer axle is solid output shaft, along with tested specific type of electric machine power output structure changes the concentric twin shaft way of output into, and the electric eddy current dynamometer of solid output shaft can't be realized the requirement that this concentric twin shaft output motor two output shafts load simultaneously.
Summary of the invention
Can't realize concentric twin shaft output motor two output shafts for the electric eddy current dynamometer that overcomes solid output shaft and load the defective of requirement simultaneously, the utility model aims to provide a kind of hollow output shaft of electric eddy current dynamometer, this hollow output shaft can satisfy the requirement of the test load of concentric twin shaft output motor, can be concentric dual-axle motor reliable test load equipment is provided.
For achieving the above object, the technological scheme that the utility model adopted is: the hollow output shaft of described electric eddy current dynamometer, its structural feature is, comprise axle output precision in connect with the interior axle of concentric dual-axle motor hollow, be arranged on the outer hollow outer shaft output precision that connects with the outer shaft of concentric dual-axle motor of hollow interior axle output precision, described hollow interior axle output precision and hollow outer shaft output precision coaxial inner conductor.
Further, described hollow interior axle output precision preferably links by the interior axle of interior axle connection spline with concentric dual-axle motor.
Further, described hollow outer shaft output precision preferably links by the outer shaft of outer shaft connection spline with concentric dual-axle motor.
A described hollow interior axle output precision preferably is contained in the hollow outer shaft output precision by bearing.
Further, described hollow outer shaft output precision periphery is provided with inductive disks, this inductive disks shape is just as spur gear, when inductive disks was rotated in magnetic field by prime mover drive, air gap flux density is the generating period variation with the rotation of inductor, will produce the eddy current electromotive force in eddy current annular distance wall surface and certain depth scope, and generation eddy current, the formed magnetic field of this eddy current interacts with air-gap field again, has just produced retarding torque, reaches the purpose of absorbing load.
Nationality is by said structure, the hollow outer shaft connection spline of electric eddy current dynamometer links with the outer shaft of concentric dual-axle motor, realize the loading of the outer output shaft of concentric dual-axle motor, the interior output shaft of concentric dual-axle motor is connected spline with the interior axle of hollow shaft electric eddy current dynamometer and links to each other, by the interior axle in the hollow shaft power measurer transmission of power is come out, link to each other with the common electrical eddy current dynamometer again, realize the loading of the interior output shaft of concentric dual-axle motor.
Compare with existing output shaft, the beneficial effects of the utility model are: the utility model has solved the requirement of the test load of concentric twin shaft output motor, for concentric dual-axle motor provides reliable test load equipment.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
