The invention relates to electrical engineering and can be used in emergency situations when failure of the primary diesel or catechesi energy have the ability to replace a failed primary diesel or gasoline engine or electric generator.A device - an electric power source that contains the primary diesel or gasoline engine and an electric generator connected using couplings and mounted on a common frame.A disadvantage of the known device is that in case of failure, it must be completely replaced by a new one.The aim of the invention is the possibility of replacement in emergency situations faulty source of electrical energy, which failed only the primary engine or electric generator, not suitable for power, but different in type and method of attachment to the frame of the primary engine or electric generator instead of the whole source of electrical energy.This is achieved by the fact that when the failure of the electric power source in emergency situations is to replace only the failed primary electric motor or generator similar capacity, mounted on separate frames, instead of replacing the entire electric power source. The proposed device is distinguished by the presence of a universal joint with two shafts, flange for rigid detachable connection of one shaft with a rotating e what about the generator to transmit the kinetic energy of the primary motor shaft of the electric generator to generate electric power.In Fig. 1 and 2 presents the electric power source for emergency situations.The electric power source for emergency situations has a primary diesel or gasoline engine 1 mounted on a separate frame 2, the universal joint 3 with two shafts 4, 5, and one end of the shaft 4 by a flange 6 is rigidly Rethimno connected with the rotating element of the Prime mover 1 and the other end of the shaft 5 through the sleeve 7 is rigidly Rethimno connected to the shaft 7 of the electric generator 9, left on old frame 10, with which the shot is defective primary engine.Then for a more rigid connection of the device with two lateral sides of both frames 2, 10 eyelets or openings 11, 12, intended for loading (unloading), elongated metal rods 13 by means of turnbuckles 14. If necessary, the frame 2, 10 in the four corners can be fixed anchor device 15.The proposed electric power source for emergency works in the following way. Defective primary engine removed from the frame of the source of electrical energy. New primary engine 1 (see Fig. 2), attached to a separate frame 2 is installed is about to couple the rotating element 16 of the primary motor 1 and the shaft 8 of the electric generator 9 through a universal joint 3 with two exhaust shafts 4, 5 with the flange 6 and the sleeve 7.The flange 6 by means of bolts 17 is attached to the rotating element 16 of the primary engine 1. In the flange is inserted into one of the shafts 4 universal joint 3 and is fixed by means of mounting bolts 18 and pins 19. On the second shaft 5 universal joint 3 is placed the sleeve 7 and is fixed by means of the adjusting screws 20 and pins 21. Further, the sleeve 7 is connected with the shaft 8 of the electric generator 9 and is fixed with an adjusting bolt 22 and pins 23.For the rigidity of the primary engine 1 and the electric generator 9, mounted on separate frames 2, 10, pull together for the eyelets (holes 11, 12 metal rods 13, connected by turnbuckles 14. If necessary, the frame 2, 10 in the four corners may optionally be attached anchor device 15. The mechanical energy from the Prime mover through its rotating element 16, the flange 6, the universal joint 3 with two shafts 4, 5, the sleeve 7 is transmitted to the shaft 8 of the electric generator 9 and the generated electric energy from the generator is delivered to the consumer.In order to reduce the circumference of rotation of the universal joint with one of the shafts shafts make shorter. Likewise, be RABC, and the electric generator. I.e. have healthy primary engine undock faulty electrical generator, remove the frame and then available on a separate frame of an electrical generator, suitable for power instead of failed, through universal joint with two shafts, a sleeve and a flange to connect to the primary engine, which remained the source of electrical energy on the old frame. The frame in turn draw metal rods with turnbuckles and fix more anchoring devices as needed.The proposed electric power source for emergency situations will improve maintainability both in the field and stationary conditions, especially cramped. In addition, replacement of defective only primary electric motor or generator will reduce the time to recovery of the source of electrical energy, which in turn will allow some savings due to early production of electricity consumers; to give greater economic impact by replacing only the defective primary electric motor or generator, and not the entire source. SOURCE ELECTR the Contracting element and an electric generator, each of which is placed on the corresponding frame, characterized in that it has two shafts, one ends of which are connected with the cardan joint, two threaded bushings, two studs and flange, while the other end of the first shaft through a flange is attached to the rotating element of the primary engine, the other end of the second shaft through one of the threaded bushing connected to the shaft of the electric generator, and the frame of the primary engine and the electric generator interconnected by means of pins and the second threaded sleeve.
