Description
Technical field
The utility model relates to bent axle technical field, be specifically related to a kind of motor 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, and reduceIts fatigue strength, and the assembly and disassembly of some bent axles is also very inconvenient, therefore needs to improve.
Utility model content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of motor bent axle, structure letterSingle, easy to use and reliable, can greatly improve the fatigue strength of bent axle, practical, assembly and disassembly is convenient.
To achieve these goals, the utility model is to realize by the following technical solutions: motor bent axle, comprisesOne trunnion, the second trunnion, key, bearing, the shaft shoulder, crank, connecting rod neck, the first helical gear, the second helical gear and arc chord angle, theOne trunnion outer end is provided with key, and first trunnion the inner is provided with bearing, and bearing is arranged on the shaft shoulder, and bearing inner side arrangesHave crank, be connected with connecting rod neck between crank, connecting rod neck and crank junction are provided with the arc chord angle of fillet rolling, crank anotherSide is provided with the second trunnion, is disposed with the first helical gear, the second helical gear on the shaft shoulder of the second trunnion.
As preferably, the second described helical gear shaft shoulder is higher than the second helical gear shaft shoulder.
The beneficial effects of the utility model: simple in structure, easy to use and reliable, the fatigue that can greatly improve bent axle is strongDegree, practical, assembly and disassembly is convenient.
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: motor bent axle, comprises the first trunnion 1, secondTrunnion 2, key 3, bearing 4, the shaft shoulder 5, crank 6, connecting rod neck 7, the first helical gear 8, the second helical gear 9 and arc chord angle 10, the firstTrunnion 1 outer end is provided with key 3, the first trunnion 1 the inners and is provided with bearing 4, and bearing 4 is arranged on the shaft shoulder 5, in bearing 4Side is provided with crank 6, is connected with connecting rod neck 7 between crank 6, and connecting rod neck 7 and crank 6 junctions are provided with the circular arc of fillet rollingAngle 10, crank 6 opposite sides are provided with and on the shaft shoulder of the second trunnion 2, the second trunnions 2, are disposed with the first helical gear 8,Two helical gears 9.
It should be noted that the shaft shoulder of the second described helical gear 9 is higher than the shaft shoulder of the second helical gear 8.
This detailed description of the invention is connected with the piston rod of internal combustion engine by rod journal 3, by piston rod up and down reciprocatinglyConversion of motion is rotatablely moving of the first trunnion and the second trunnion, is driven and is sent out by the first helical gear 8, the second helical gear 9The rotation of the rotary main shaft of motor realizes generating. The shaft shoulder, in the time of running in bearings, can be avoided the scuffing to trunnion, has assemblingAdvantage, has the arc chord angle forming for fillet rolling between connecting rod neck and crank comparatively reliably, can avoid connecting rod neck withStress between crank is concentrated, and has increased bonding strength.
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.
