Description
Affiliated technical field
The utility model content belongs to the electromechanical device technical field, relates to the improvement structure of a kind of vapour (bavin) diesel engine.
Background technology
Along with current rapid development of social economy, worldwide day barrier is obvious for the contradiction of energy scarcity, and the situation of power cuts to limit consumption and power failure often takes place in daily life and the production.For the needs of emergent production, life or field work, diesel engine is widely used.Conventional diesel engine mainly is made up of three parts, be oily machine, generator and shaft joint or connection belt, wherein oily machine and generator all have fixed support and foundation separately, the practical structures of product exists defectives such as volume is big, Heavy Weight, efficient is low, oil consumption is high, resettlement is difficult, is unsuitable for field work living environment and uses.The problems referred to above skyrocket, pursue benefit and especially make us anxiety today of the type society that advocates thriftiness in energy scarcity, oil price, how to improve diesel engine efficient, energy savings, alleviate product weight and become the particularly focus paid close attention to of this area scientific and technical personnel of the whole society.
The utility model content
The utility model aims to provide a kind of synchronous generator for integrated rotary-magnetic external rotor oil press, thereby overcome defectives such as the volume that prior art exists is big, Heavy Weight, efficient is low, energy waste is big, reach raise the efficiency, the purpose of weight reduction, convenient work life.
Technical solution of the present utility model is obtained by prior art products rationally improves on mounting structure, its key points in design is: the synchronous generator for integrated rotary-magnetic external rotor oil press that is provided is by support, fuel tank, oil machine and rotary-magnetic external rotor synchronous generator are formed, fuel tank and oily machine is rack-mount, the magnetic external rotor of generator is fixed in the rotating shaft of oily machine, simultaneously the stator of generator is arranged in the magnetic external rotor and by motor housing with one heart and fixedlys connected, leave appropriate gap between stator and the magnetic external rotor with oily engine housing.In the real work, behind oil start, the magnetic external rotor of generator together rotates with oily machine rotating shaft, causes the magnetic flux change in the stator coil, produces electric energy, and then exports electric energy by the lead-in wire of coil, reaches the purpose of generating.
Compare with existing like product, the advantage that the utility model had is: 1. when oily machine and generator assembling, broken through in the past the pattern that both are connected after the independent stationary respectively again, but generator directly is fixed in the rotating shaft and shell of oily machine, save the fixed support and the accessory of generator, alleviated weight and volume, on the model machine of making, generator is just as an accessory on the oily machine, and volume is very little, realizes the machine integrated and miniaturization of hydro power generation; 2. change the relation of conventional power generation usage machine rotor and stator, on diesel engine, adopt high magnetic permanent-magnetic outer rotor first, like this under the equal volume situation, the magnetic field intensity that produces is stronger, efficient is higher, and saved magnet exciting coil, the purpose of reach weight reduction, reduced volume, raising the efficiency; 3. stator is made up of the iron core and the coil windings of high permeability material making, during at ordinary times with work, stator remains static all the time, can export from the stator coil wiring easily, saved the carbon brush in the conventional generator, alleviated weight, because this output connected mode is subjected to load effect less, even the short time short circuit appears in generator, can not damage winding coil yet.
The design of synchronous generator for integrated rotary-magnetic external rotor oil press described in the utility model is come out, and has realized that diesel engine is really integrated.The volume of this generator product is little, in light weight, compact conformation, portable, voltage is stable and efficient is high, can be used for the frontier sentry of army, remote company of battalion routine work life, solve the difficult problem of army's Field Integrated Communication System power supply, also can be used for every aspects such as field work, tourism, fisherman are gone to sea, mountain area generating, solve problems such as communication, illumination, compact electric apparatus electricity consumption, for users save cost, providing convenience, also is that the national in recent years conservation-minded society that advocates energetically makes great contribution simultaneously.

Embodiment
Referring to accompanying drawing, synchronous generator for integrated rotary-magnetic external rotor oil press described in the utility model is made up of fuel tank 1, oily machine 2, support 3 and rotary-magnetic external rotor synchronous generator 4, fuel tank 1 and oily machine 2 are installed on the support 3, generator 4 as same parts are fixed in the rotating shaft and housing of oily machine 2, have reduced volume and weight.During 2 work of oil machine, provide oil plant by fuel tank 1, oily machine 2 is mechanical energy by incendiary oil with thermal power transfer, oily arbor is rotated, drive magnetic external rotor 43 rotations in the generator 4, make winding magnetic flux change in the stator 46, produce electromotive force, output potential is finished the hydro power generation process.
The structure of the used rotary-magnetic external rotor synchronous generator 4 of the utility model is shown in Fig. 3～7, and it mainly is made up of parts such as shell 41, magnetic external rotor 43 and stators.Fixedly case 43a and the high magnetic permanent magnet 43b that is fixed on the case madial wall constitute magnetic external rotor 43 by magnet, case 43a is fixed in the rotating shaft of oily machine 2 by attachment screw 44, be used for fixing permanent magnet 43b, and the permanent magnet fragmentation flies out when preventing that rotor high-speed from rotating.Being arranged at conducting magnet core 46a that the generator unit stator 46 in the magnetic external rotor 43 made by the high magnetic permanent magnetic material of a plurality of coaxial symmetrically arranged usefulness and the coil 46b that is wound on respectively on each iron core with one heart constitutes, leave appropriate gap (being not less than 0.1mm) between stator 46 and the magnetic external rotor 43, so that magnetic external rotor 43 rotates.Motor housing 41 is a coaxial outer semiclosed shape housing of magnetic external rotor 43 that covers at, and main effect is to protect generator and fixing nail.By set bolt 42 motor housing 41 is connected on the oily engine housing during assembling, the center shell wall of motor housing 41 is connected with the central shaft of stator 46 by stator hold-down screw 45.
By Fig. 1 and 3 as can be seen: magnetic external rotor 43 is installed on the oily arbor cleverly, and has saved magnet exciting coil and part generator housing, has improved efficient, has reduced weight and volume.Coil windings is installed on the stator 46, has saved carbon brush, and is directly by winding coil output, convenient, even the short time short circuit can not burn out coil yet.Because rotary-magnetic external rotor synchronous generator (under identical power conditions) volume is very little, it can be fixed on easily on the oily machine shell, realizes integrated.
