Description
Technical field
The utility model belongs to gasoline engine generator parts technical field, more particularly, to a kind of generator Crank connected rod group
Part.
Background technique
Crankshaft-link rod component is the main movement mechanism of generator, and function is that the reciprocating motion of piston is changed into crankshaft
Rotary motion, while the power that will act on piston is changed into the torque that crankshaft externally exports, with the rotation of driven generator.
The crankshaft of traditional crankshaft-link rod component is integral type, and the neck of the crankshaft of integral type is more difficult to process, machining accuracy
It is not easy to control, using effect and the service life of crankshaft-link rod component will be directly influenced.Since crankshaft-link rod component is in the course of work
In, connecting rod does high speed rotary motion relative to crankshaft, if connecting rod and crankshaft phase mutual friction, it will bring larger damage to components
Wound, while largely effecting on generating efficiency.
Utility model content
In place of the purpose of this utility model is the deficiencies in the prior art to be solved, and provide that a kind of precision is high, generating efficiency
High generator crankshaft-link rod component.
The purpose of this utility model is solved through the following technical scheme:
A kind of high performance generation machine crankshaft link assembly, it is characterised in that: include crankshaft, needle bearing and connecting rod；
The crankshaft is split type structure, including crank-pin, left crank and right crank；
It is arranged with needle bearing in the middle part of the crank-pin, is arranged with connecting rod outside needle bearing, crank-pin left end is arranged with a left side
Crank, crank-pin right end are arranged with right crank, and left crank and right crank are separately positioned on the left and right sides of connecting rod.
The first friction plate is equipped on the left of the connecting rod, the first friction plate is between connecting rod and left crank；It is set on the right side of connecting rod
There is the second friction plate, the second friction plate is between connecting rod and right crank.
Further, left ball bearing is arranged on left crank described in the utility model；The right side is arranged on the right crank
Ball bearing and timing gears, timing gears are located on the right side of right ball bearing.
Further, the material of connecting rod described in the utility model is 20CrMo steel alloy.
Further, rod surface described in the utility model is equipped with carburizing and quenching layer.
Compared to the prior art the utility model have the characteristics that and the utility model has the advantages that
1, by the change to crankshaft structure, monoblock type is changed to it is split type, the ratio of precision monoblock type neck of crank-pin
Precision is good, keeps generator work more smooth, it is ensured that working efficiency.
2, it is equipped with the first friction plate between connecting rod and left crank, between the second friction plate of connecting rod and right crank, can effectively keep away
Exempt from phase mutual friction between connecting rod and left and right crank, effectively prolong its service life and ensures its generating efficiency.
3, by adding a needle bearing in connecting rod and crank-pin junction, reduce connecting rod rubbing during the work time
Coefficient is wiped, lubricity is enhanced, improves working efficiency.
4, connecting rod changes 20CrMo steel alloy by original aluminum component, and handles by carburizing and quenching, enhances its wearability, prolongs
Its long service life.

The first friction plate 9 is equipped on the left of connecting rod 3, the first friction plate 9 is between connecting rod 3 and left crank 1；3 right side of connecting rod
Equipped with the second friction plate 10, the second friction plate 10 is between connecting rod 3 and right crank 2.It can effectively avoid connecting rod 3 and left and right song
Phase mutual friction between handle effectively prolongs its service life and ensures its generating efficiency.
Left ball bearing 6 is arranged on left crank 1；Right ball bearing 7 and timing gears 8 are arranged on the right crank 2,
Timing gears 8 are located at right 7 right side of ball bearing.
Wherein, the material of connecting rod 3 is preferably 20CrMo steel alloy, in order to further increase 3 performance of connecting rod, in 3 table of connecting rod
Face is equipped with carburizing and quenching layer, enhances its wearability, prolongs its service life.
The utility model improves the service life of crankshaft, extends to original 60 hours service life existing 200 hours
Service life, and manufacturing cost reduces 10%, more competitive on the market.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
