Description
Technical field
The utility model relates to crankshaft structure technical field, be specifically related to a kind of New-type electric machine bent axle.
Background technology
Bent axle is the main rotary gadget of engine or generator, loads onto after connecting rod, can accept connecting rod up and down reciprocatinglyMotion becomes circulation rotating motion, and its material is made up of carbon structural steels or spheroidal graphite cast-iron, and it has three significant points:Trunnion, connecting rod neck and crank. The connecting rod neck of traditional motor bent axle and crank junction easily produce stress and concentrate, greatlyReduce its fatigue strength, and the assembly and disassembly of some bent axles is also very inconvenient, easily injures main shaft, therefore needs traditional songAxle construction is improved.
Utility model content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of New-type electric machine bent axle, knotStructure is simple, easy to loading and unloading reliable, the service life that can greatly improve bent axle.
To achieve these goals, the utility model is to realize by the following technical solutions: New-type electric machine bent axle, bagDraw together the first central shaft, the second central shaft, keyway, key, timing gears, balance gear, crank, rod journal and external screw thread, firstCentral shaft end is provided with keyway, and the second central shaft end is provided with external screw thread, the first central shaft inner side be provided with timing gears,Balance gear, balance gear opposite side is provided with crank, between crank, is connected by rod journal, described crank and pitman shaftNeck junction is provided with the concave arc of fillet rolling.
As preferably, on the crank of the second described central shaft side, be provided with balancing weight.
The beneficial effects of the utility model: simple in structure, easy to loading and unloading reliable, the use longevity that can greatly improve bent axleLife.
Brief description of the drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, belowIn conjunction with detailed description of the invention, further set forth the utility model.
With reference to Fig. 1, this detailed description of the invention by the following technical solutions: New-type electric machine bent axle, comprise the first central shaft 1,The second central shaft 2, keyway 3, key 4, timing gears 5, balance gear 6, crank 7, rod journal 8 and external screw thread 9, the first central shafts1 end be provided with keyway 3, the second central shaft 2 ends be provided with external screw thread 9, the first central shaft 1 inner sides be provided with timing gears 5,Balance gear 6, balance gear 6 opposite sides are provided with crank 7, between crank 7, are connected by rod journal 8, described crank 7 withRod journal 8 junctions are provided with the concave arc of fillet rolling.
On the crank 7 of the second central shaft 2 sides described in it should be noted that, be provided with balancing weight.
Between the rod journal of this detailed description of the invention and crank, there is the arc groove forming for fillet rolling, canAvoid the stress between rod journal and crank to concentrate, increased bonding strength; Simple in structure, easy to loading and unloading reliable, Neng Gou greatLarge service life of improving bent axle.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model. One's own professionThe technical staff of industry should understand, and the utility model is not restricted to the described embodiments, and in above-described embodiment and description, describesPrinciple of the present utility model is just described, do not departing under the prerequisite of the utility model spirit and scope, the utility model alsoHave various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model. The utility modelClaimed scope is defined by appending claims and equivalent thereof.
