Abstract
A high speed, over loading and middle-small size generator testing device, characterized in that inner hole of left jaw shaft joint is in flat key connection with diameter of shaft extension end of a electrical motor, inner hole of right jaw shaft joint is in flat key connection with diameter of shaft extension end of a electrical motor, two flat keys are leaned against with hex bolts and locked with hex nut; left jaw shaft joint and right jaw shaft joint are integrally located via tab and notch, end faces are mutually engaged in convex and concave formation, and connected with bolts; this utility model has advantages of: 1. nice neutral performance, high connection strength; 2. shaft joint transmits great torque and high speed; 3. high reliability of flat key connection ensured; 4. capable of adjusting height and size of installation plate according to different center heights of high speed electrical motor.
Description
Technical field
The utility model relates to a kind of generator test device, relates in particular to a kind of high speed, heavy duty, medium and small generator test unit.
Background technology
In, low-speed generator (rotating speed is no more than 3000r/min) motor test, generally use flange-face coupling or rubbercushioned sleeve bearing coupling, provide power by motor, by connecting, drive generator and rotate with upper coupling, can carry out generator test.But for the high-speed electric expreess locomotive of rotating speed in 3000～6000r/min scope, if still adopt flange-face coupling or rubbercushioned sleeve bearing coupling, then because the motor speed height, moment of torsion is big, coupling bolt or pin are prone to crackle even fracture, this moment, these two kinds of shaft couplings all can not satisfy request for utilization, so need to solve high speed, heavy duty, medium and small generator test problem.
Summary of the invention
The purpose of this utility model is to provide a kind of high speed, heavy duty, medium and small generator test unit, is used to solve the problem of transmission of high speed, heavily loaded motor power and speed, thereby can test the medium and small generator of high speed convenient, effectively.
The utility model is achieved like this, it comprises motor, motor mounting plate, hex bolts, hexagonal nut, left tooth embedding shaft coupling, right tooth embedding shaft coupling, coupling bolt, generator, generator installing plate, T-nut, guide rail, U-shaped protective cover, it is characterized in that left tooth embedding shaft coupling endoporus adopts flat key to be connected with the shaft extension end diameter of axle of motor, right tooth embedding shaft coupling endoporus also adopts flat key to be connected with the shaft extension end diameter of axle of generator, two flat keys all with hex bolts prop up, hexagonal nut locks; Left side tooth embedding shaft coupling, right tooth embedding shaft coupling be with convex shoulder and groove fit location, and end face adopts recessed thread form, protruding thread form chimeric mutually, and connect with bolt; By height dimension and T-nut the moving in guide rail of adjusting two motor mounting plates, can satisfy the test of the high-speed engine of different height of centers, different installation dimensions.
The utility model has the advantages that: 1, left tooth embedding shaft coupling, right tooth embedding shaft coupling are located with convex shoulder and groove fit, and connect with bolt, have the advantage good to neutrality, that strength of joint is high; 2, left tooth embedding shaft coupling, right tooth embedding coupling end-face adopt the concave, convex thread form chimeric mutually, and the moment of torsion that its shaft coupling transmitted is big, the rotating speed height; 3, adopt standard fasteners locking flat keys such as hex bolts, hexagonal nut, can guarantee the reliability that flat key connects; 4, the height of center different according to high-speed electric expreess locomotive can be adjusted the height dimension of installing plate; 5,, adopt T-nut in guide-track groove, to slide and the lateral dimension of adjusting guide rail guarantees for satisfying the high-speed engine installation requirement of different installation dimensions; 6, for guaranteeing the personal safety of testing crew, above shaft coupling, cover a U-shaped protective cover, and be fixed on the guide rail.
