Description

A kind of alternating current generator

The utility model belongs to a kind of automobile-used electric electrical energy supply device.

In order to satisfy Hyundai Motor, require that the vehicle alternator volume is little, reliable in structure, generating capacity is strong, work is lasting to development need high-grade, comfortable, electric automatization.And present domestic 500W-1400W alternating current generator, its power is less relatively, and particularly power is on the low side under the low speed situation, and physical dimension is bigger, and consumptive material is many, and power generation performance and dependability can not adapt to the needs of Hyundai Motor and other configuration electrical equipment development.

The purpose of this utility model provide a kind of rational in infrastructure, power is big, volume is little, the novel alternating current generator of dependable performance.

The utility model is achieved through the following technical solutions:

A kind of alternating current generator, by field frame assembly, rotor assembly, belt pulley, rectifier stack, rear bearing, brush and governor assembly, the front end housing assembly, rear end cap, back door is formed, it is characterized in that: the stator core of described field frame assembly is of a size of: external diameter Φ 136～138mm, internal diameter Φ 106～108mm, thickness 30～32mm, slip ring assembly in the described rotor assembly is reached by two slip rings and the lead-in wire and the heat curing-type insulating material of its welding are hot pressed into integral body, lead-in wire is at one end drawn, other end band tension disc, have two axial lead holes in described insulating material, the solder joint of the lead-in wire of field winding and slip ring lead-in wire places the outside of rotor assembly in the rotor assembly.

Above-mentioned alternating current generator, its characteristics are: described stator core is of a size of: external diameter Φ 136mm, internal diameter Φ 106mm, thickness 30mm.

Above-mentioned alternating current generator, its characteristics are: the spindle nose of described rotor assembly and belt pulley union end is partly processed a platform, adorns six square washers that match with it when belt pulley and propeller shaft couplings on platform.

Above-mentioned alternating current generator, its characteristics are: described front end housing assembly and rear end cap seam partly are the convex-concave engagement.

Above-mentioned alternating current generator, its characteristics are: be provided with an open slot in the described rear end cap bearing chamber, put into rubber ring in the groove.

Above-mentioned alternating current generator, its characteristics are: described rectifier stack adopts cast aluminium to do heating panel, and the rectifier stack leader adopts multiway clamping welding manner to connect with the field frame assembly lead-in wire.

Adopt such scheme, the utility model power is 2200W, with respect to equal power product volume is little, economizes on material both at home and abroad, adopts multiple reliable version, improves Performance And Reliability.

The utility model is described in further detail below in conjunction with accompanying drawing

By among Fig. 1, Fig. 4 as can be known, pad 1, nut 2, belt pulley 3, rotor assembly 4, front end housing 5, field frame assembly 6, rear end cap 7, field winding 8, slip ring assembly 9, brush and governor assembly 10, rubber ring 11, rear bearing 12, rectifier stack 13, back door 14, slip ring lead-in wire 15, the structural relation of fairlead 16.The utility model is to implement like this: the fairlead 16 and 15 welding of slip ring lead-in wire that the lead-in wire of field winding 8 in the rotor assembly 4 are passed slip ring assembly 9, add in fairlead 16 and slip ring assembly 9 endoporus simultaneously that fixing glue makes that lead-in wire and fairlead are fixed, slip ring assembly and power transmission shaft fix, become rotor assembly, rotor assembly successively with front end housing assembly 5, field frame assembly 6, belt pulley 3, rear end cap 7, rectifier stack 13, brush and governor assembly 10, back door 14 assemblings.Because field winding lead-in wire and the close to greatest extent generator shaft of the solder joint of slip ring lead-in wire, make the solder joint radius reduce to minimum, solder joint place linear velocity descends, reduce the centrifugal force at solder joint position and rotated destruction, make the vibration resistance of rotor assembly, anti-high speed and insulation property have all had essential difference, in slip ring assembly, establish simultaneously fairlead, make the outside of solder joint at rotor assembly, fixed with special fixing glue when mounted, to reach the antivibration ability, the operating position that this structure particularly is fit to run up and vibration condition is abominable simultaneously, can make the field winding lead-in wire not fragile in assembling process, and it is fixing reliable, thoroughly solved fishing line, short circuit, fault such as open circuit has greatly improved product reliability, and, field frame assembly adopts import equipment to carry out rule, winding adopts 1.3 pairs of composite bed high-temperature resistant enamelled wires of 2 * Φ, and forms through dipping lacquer repeatedly, the reliability when guaranteeing the high-power output of generator.

Partly processing a platform L at rotor assembly 4 with the spindle nose of belt pulley 3 union ends is 15.6mm, install six square washers 1 that match with it herein additional, because the effect of platform, six square washers 1 can not produce circumferential rotation with axle, when nut 2 is applied in the regulation screw-down torque, six square washers 1 will be close to belt pulley 3 end faces, because the hexagon area is big and do not have circumferential rotation displacement with axle, make belt pulley 3 and the axle between driving force much larger than the driving force that directly compresses by nut 2, and can not become flexible, thereby guarantee that alternating current generator rotates normally under any operating position because of belt pulley alternation rotating speed makes nut 2.

With the seam partial design of front end housing 5 and rear end cap 7 is the convex-concave engagement, has increased the faying face of forward and backward end cap and stator, has improved integral rigidity, has improved the reliability that motor uses.

In the rear end bearing chamber, process a groove, put into an oil resistant, resistant to elevated temperatures rubber ring 11, utilize it to expand and compressible distortion, making between rear end cap 7 and the rear bearing 12 has one to conform to power more greatly, prevent to relatively rotate between bearing outer ring and end cap and cause wearing and tearing, simultaneously, the cold cure process of doing is adopted on rear end cap 7 bearing chambers surface, improve case hardness and wear-resisting, crush resistance.

Rectifier stack adopts cast aluminium to do heating panel, not only makes the rectifying tube heat radiation be able to further improvement, and reduces cost.Rectifier stack leader and field frame assembly lead-in wire adopt the welding of multiway clamping welding manner to improve reliability.
