A bent axle with major -minor balancing piece, includes the balancing piece that sets up on bent axle body and the bent axle body, the bent axle body with balancing piece integrated into one piece, the balancing piece includes main balancing piece and vice balancing piece, main balancing piece and vice balancing piece lie in same one side of bent axle body, and parallel arrangement, and the outer radius of circle of main balancing piece is greater than the outer radius of circle of vice balancing piece. The utility model discloses design into two balancing piece structures of unequal one main a pair of radius with two balancing pieces in the prior art bent axle, can satisfy the inside space layout requirement of conventional single cylinder diesel, just reach 100% balance of rotatory inertial force again.
Description
Technical field
This utility model belongs to engine component technical field, is related to a kind of engine crankshaft balance block structure, especially
It is a kind of suitable for 100～105mm of cylinder diameter, stroke among 85～90mm high direct injection air-cooled single-cylinder diesel engine with major-minor
The bent axle of balance weight.
Background technology
As the rotating speed for continually strengthening electromotor of high-power diesel acc power is increased substantially.To engine movements part
Structural reliability and compact have requirements at the higher level.By integrated crankshaft designs, diesel engine movement parts structure and connected mode are made
It is simplified, is conducive to reliable high-efficiency operation under high speed, high load working condition.Simultaneously integrated crankshaft designs can reduce bent axle volume
Size, is conducive to electromotor compact, light-weighted design.
Crankshaft of diesel engine is the ingredient of balance system, and balance weight is designed on bent axle makes whole bent axle have out-of-balance force
Square, this unbalanced moments is used for the turning moment of balanced connecting rod major part, and conventional single cylinder diesel is due to technological requirement and space cloth
Put, often two balance weights of bent axle are designed to into uniform thickness or wait radius, but 100% balance of rotating inertia force can not be reached.
Utility model content
The technical problems to be solved in the utility model is：Based on the problems referred to above, there is provided a kind of song with major-minor balance weight
Axle, can meet conventional single cylinder diesel inner space arrangement requirement, and just reach 100% balance of rotating inertia force.
This utility model solves the technical scheme that its technical problem adopted：A kind of bent axle with major-minor balance weight,
Including the balance weight arranged on crankshaft body and crankshaft body, the crankshaft body is integrally formed with the balance weight, described flat
Weighing apparatus block includes main balance weight and secondary balance weight, and the main balance weight and secondary balance weight are located at the same side of crankshaft body, and parallel
Arrangement, the exradius of main balance weight is more than the exradius of secondary balance weight.
Further, the top of the major and minor balance weight is respectively provided with crank arm, and between two crank arms connecting rod neck is provided with.
Further, oil hole is offered on the connecting rod neck.
Further, the main balance weight has been orderly arranged outside each balance shaft gear gear, bearing rib, Rear oil seal gear, flywheel
Axis of cone section and flywheel nut section are installed, the secondary balance weight has been orderly arranged outside each reinforcement convex shoulder section, timing gears and has installed
Gear, trunnion, Front oil seal section and outfan.
The beneficial effects of the utility model are：Two pieces of balance weights in prior art bent axle are designed to half by this utility model
The secondary two pieces of balance block structures of a master one that footpath is not waited, can meet conventional single cylinder diesel inner space arrangement requirement, and just
Reach 100% balance of rotating inertia force.

Exradius.
Wherein, the top of major and minor balance weight 2,3 is respectively provided with crank arm 4, and between two crank arms 4 connecting rod neck 5, connecting rod are provided with
Oil hole 6 is offered on neck 5.Main balance weight 2 has been orderly arranged outside each balance shaft gear gear 7, bearing rib 8, Rear oil seal gear 9, has flown
Wheel installs axis of cone section 10 and flywheel nut section 11, and secondary balance weight 3 has been orderly arranged outside each reinforcement convex shoulder section 12, timing gears
Gear 13, trunnion 14, Front oil seal section 15 and outfan 16 are installed.
It is air-cooled that the crankshaft body 1 of this practical example is used for 100～105mm of cylinder diameter, the stroke high direct injection in 85～90mm
Single cylinder diesel, preferably, the exradius of main balance weight 2 is 76mm, and the exradius of secondary balance weight 3 is 54mm.
With it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, by above-mentioned description, related work people
Member can carry out various change and modification in the range of without departing from this utility model technological thought completely.This reality
The content being not limited to new technical scope in description, it is necessary to its technology is determined according to right
Property scope.
