Description
Technical field
This utility model relates to motor device technical field, the crankshaft group that a kind of production cost is low.
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 existing crankshaft structure is complicated, volume is big, and production cost is high.
Utility model content
The purpose of this utility model is the crankshaft group providing a kind of production cost low, to solve in above-mentioned background technology
The problem proposed, had the beneficial effect that simple in construction, volume is little, reasonable in design, reduces production cost, by logical
Cross rod journal to be attached, it is simple to remove and install, practical.
For achieving the above object, this utility model following technical scheme of offer: the crankshaft group that a kind of production cost is low, bag
Including short crank, connecting rod, rod journal and long crank, described short crank is connected with long crank by rod journal, and rod journal
Being positioned at the upper end of short crank and long crank, described rod journal is connected with connecting rod by the bearing of connecting rod bottom, and rod journal
Being connected by pivot pin and bearing are fixing, described short crank is provided with short crank spindle neck, and short crank away from the side of rod journal
Trunnion is provided with keyway, and described long crank is provided with long crank spindle neck away from the side of rod journal.
Preferably, the diameter of described short crank spindle neck and the equal diameters of long crank spindle neck.
Preferably, described keyway is semicircle keyway.
Preferably, the middle position strip groove of described connecting rod.
Preferably, the described short crank middle position near rod journal side is provided with short crank recess, described long song
The handle middle position near rod journal side is provided with long crank recess.
Compared with prior art, the beneficial effects of the utility model are: this device structure is simple, and volume is little, reasonable in design,
Reduce production cost, by being attached by rod journal, it is simple to remove and install, practical.

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.
Refer to Fig. 1-2, a kind of embodiment that this utility model provides: the crankshaft group that a kind of production cost is low, including
Short crank 3, connecting rod 4, rod journal 5 and long crank 7, short crank 3 is connected with long crank 7 by rod journal 5, and rod journal
7 upper ends being positioned at short crank 3 and long crank 7, rod journal 5 is connected with connecting rod 4, in connecting rod 4 by the bearing of connecting rod 4 bottom
Between position director's bar shaped groove, and rod journal leads to 5 and crosses pivot pins 6 and bearing and fix and be connected, and short crank 3 is away from rod journal 5
Side is provided with short crank spindle neck 2, and short crank spindle neck 2 is provided with keyway 1, and keyway 1 is semicircle keyway, and long crank 7 is remote
Long crank spindle neck 8 it is provided with, the diameter phase of the diameter of short crank spindle neck 2 and long crank spindle neck 8 from the side of rod journal 5
Deng, the short crank 3 middle position near rod journal 5 side is provided with short crank recess, and long crank 7 is near rod journal 5 one
The middle position of side is provided with long crank recess.
Work away from: during use, drive the rotation of short crank 3 and long crank 7 to transport by pumping of connecting rod 4
Dynamic, then by the main axis of the gear driven motor on the shaft shoulder, thus realize 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
