Description
Technical field
This utility model relates to motor device technical field, the long crank of a kind of crankshaft group.
Background technology
Bent axle is the main rotary gadget of electromotor or electromotor, after loading onto connecting rod, can accept connecting rod up and down reciprocatingly
Motion 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: main
Axle journal, rod journal and crank.But the long crank structure of existing bent axle is more complicated, and production routine is more complicated, production cost
Higher.
Utility model content
The purpose of this utility model is to provide the long crank of a kind of crankshaft group, to solve to propose in above-mentioned background technology
Problem, had the beneficial effect that simple in construction, reasonable in design, easy accessibility, the most easily manufactured, reduce production
Cost.
For achieving the above object, this utility model following technical scheme of offer: the long crank of a kind of crankshaft group, including long
Crank, axis hole, long crank journal and keyway, the upper end of described long crank is provided with cylindrical part, and sets on circular cylinder shaped portion
Have axis hole, the bottom of described long crank to be provided with spade part, and spade part be provided with screwed hole, described long crank is away from spiral shell
The side of pit is provided with long crank spindle neck, and long crank spindle neck is provided with keyway.
Preferably, the two ends of described axis hole are provided with transition chamfering.
Preferably, the long crank outside described screwed hole is provided with the first groove.
Preferably, the long crank below described long crank spindle neck is provided with the second groove.
Preferably, described keyway is semicircle keyway.
Compared with prior art, the beneficial effects of the utility model are: this device structure is simple, reasonable in design, dismounting side
Just, the most easily manufactured, reduce production cost.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is side view of the present utility model；
Fig. 3 is keyway arrangements schematic diagram of the present utility model.
In figure: the long crank of 1-；2-axis hole；3-screwed hole；4-long crank spindle neck；5-keyway.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-3, a kind of embodiment that this utility model provides: the long crank of a kind of crankshaft group, including long song
Handle 1, axis hole 2, long crank journal 4 and keyway 5, the upper end of long crank 1 is provided with cylindrical part, and circular cylinder shaped portion is provided with
Axis hole 2, the two ends of axis hole 2 are provided with transition chamfering, and the bottom of long crank 1 is provided with spade part, and spade part be provided with spiral shell
Pit 3, the long crank 1 outside screwed hole 3 is provided with the first groove, and long crank 1 is provided with long crank master away from the side of screwed hole 3
Axle journal 5, the long crank 1 below long crank spindle neck 5 is provided with the second groove, and long crank spindle neck 4 is provided with keyway 5, keyway 5
For semicircle keyway.
Operation principle: during use, is arranged on long crank on connecting rod by connecting shaft and cooperating of axis hole, by even
Bar pumps and drives short crank and the rotary motion of long crank 1, then by the master of the gear driven motor on the shaft shoulder
Axle rotates, thus realizes generating.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
