Abstract
The utility model relates to a novel engine crankshaft which comprises a main journal, an output flange and a connecting rod neck, wherein a shoulder is arranged at the joint between the main journal and the output flange; two sides of the connecting rod neck are provided with main journal shoulders; and the shoulder and the main journal shoulders have the same thickness. The novel engine crankshaft is compact in structure, reasonable in design, rapid to machine and low in cost, the strength and rigidity of the crankshaft are guaranteed, the crankshaft structure is improved, and therefore the novel engine crankshaft is convenient to popularize.
Description
Technical field
The utility model relates to a kind of new work engine bent axle, and particularly a kind of engine crankshaft of processing and assembling be convenient to belongs to technical field of engines.
Background technique
At present, bent axle is one of most important in the motor, that carrying is the most complicated, price is the most expensive part.Continuous development along with technology, except the performance requirement to bent axle improves, requirement to the processing of bent axle and cost control is also more and more higher, and present many bent axles have been ignored the control of bent axle easy making process and processing cost aspect in order to pursue the simplicity of structure.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, and a kind of compact structure, reasonable in design is provided, easy making process, lower-cost new work engine bent axle.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise main journal, output flange and connecting rod neck, described main journal and output flange joint are provided with shoulder, and described connecting rod neck both sides are provided with the main journal shoulder, and described shoulder is identical with main journal shoulder thickness.
The utility model has the advantages that:
Compact structure, reasonable in design, processing is quick, cost is low, when guaranteeing crankshaft strength, rigidity, by improving crankshaft structure, is convenient to popularize.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises main journal 1, output flange 2 and connecting rod neck 3, and described main journal 1 and output flange 2 joints are provided with shoulder 5, and described connecting rod neck 3 both sides are provided with main journal shoulder 4, and described shoulder 5 is identical with main journal shoulder 4 thickness.
A kind of new work engine bent axle of the present utility model comprises main journal 1, output flange 2 and connecting rod neck 3, and main journal 1 and output flange 2 joints are provided with shoulder 5, and connecting rod neck 3 both sides are provided with main journal shoulder 4, and shoulder 5 is identical with main journal shoulder 4 thickness.The utility model is full supporting type bent axle, guarantee the prerequisite of Whole Crankshaft Strength and rigidity, between the main journal 1 of last cylinder of bent axle and output flange 2, increase by a shoulder 5, the consistency of thickness of shoulder 5 thickness and other main journal shoulders 4 can adopt unified moulding stage property in course of working, easy to process, and shoulder 5 needs accurately machined position less in the fine finishing process, both can reduce manufacturing procedure, can also reduce the tool category and the cost of charp tool, and be convenient to produce.
