Accompanying drawing explanation
Fig. 1 is the structural front view of the embodiment of the present invention.
Fig. 2 is the right view of Fig. 1.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the horizontal dynamic pressure overspeed test unit of commutator in embodiment is mainly comprised of protective cover 1, bearing 2, belt pulley 3, output shaft 4, lining 5, pressing plate 6, gland nut 7, belt 9, underframe 11, bearing seat 12 and sheet asbestos 13.
As shown in Figure 1 and Figure 2, described output shaft 4 two ends are arranged in bearing seat 12 by bearing 2 supportings respectively, bearing seat 12 is fixed on underframe 11, output shaft 4 is provided with limiting stand 14, cover has the lining 5 of detachable replacing simultaneously, the outside dimension of described lining 5 and commutator to be tested 8 endoporus are suitable, commutator 8 is placed on the lining 5 on output shaft 4, commutator 8 endoporus and lining 5 clearance fit, commutator 8 is fixing by pressing plate 6 and gland nut 7, and commutator 8 is stable when guaranteeing overspeed test; Described protective cover 1 covers on commutator 8 peripheries, and protective cover 1 is fixed on underframe 11; Described motor 10, belt 9 and belt pulley 3 form driving mechanism, and the output terminal of motor 10 is installed driving pulley, and described belt pulley 3 is fixedly mounted on output shaft 4 ends, pass through belt 9 connection for transmissions between driving pulley and belt pulley 3.
As shown in Figure 1, in the embodiment of the present invention, described protective cover 1 inside is evenly laid with sheet asbestos 13 and heating tube.Sheet asbestos 13 makes protective cover 1 heat insulation in heating process, insulation after heating.
In the present invention, described output shaft 4 is furnished with the lining 5 of various outer diameter size, can adapt to by changing the lining 5 of various outer diameter the commutator 8 of different interior hole dimensions.Can adapt to by the adjusting of gland nut 7 and pressing plate 6 commutator 8 of differing heights.Package unit is supported by underframe 11, and underframe 11 is normal welding part, guarantees that anchorage force is enough, is with underframe 11 together to carry during carrying.
During concrete application, actuating motor 10, the driving pulley of motor 10 output terminals is by belt 9 to belt pulley 3 and output shaft 4 transmitting torques, and the moment of torsion of transmission compresses by pressing plate 6 friction force producing and drives commutator 8 rotations.By changing the rotating speed of motor 10, can change the rotating speed of output shaft 4, thereby change the rotating speed of commutator 8.
The present invention is after operation, through repeatedly using, respond well.Not only reduced motor cost, again the quality of commutator 8 has been had more directly and controlled.
It should be noted that, an above-described approximate suitable application area of the present invention, the invention is not restricted to above field.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the spirit and concept in the present invention, within all should thinking and being included in protection scope of the present invention.
