Abstract
A crankshaft of two-cylinder diesel engine comprises two connecting bar shaft necks, three main shaft necks, four counterbalances and a rear end output flange piece, wherein the two connecting bar shaft necks are arranged through a 360-degree crankshaft, which changes a traditional 180-degree included angle arrangement, two connecting bar shaft necks which are arranged on the front and the rear of the crankshaft and the adjacent main shaft necks are communicated through an inclined oil hole respectively, the four counterbalances are arranged between each main shaft neck and each connecting bar shaft neck, and the counterbalances are fan-shaped structures. The crankshaft of two-cylinder diesel engine not only lowers vibration of the two-cylinder diesel engine, but also solves the rhythmic impact of longer exhausting interval time to a turbocharger, lowers noise of the diesel engine, improves the amenity of the diesel engine, simultaneously lowers friction force, centrifugal force and overturning moment of the diesel engine when rotating in high speed, can satisfy the requirements of high power, high torque and high performance per liter of the diesel engine, and has simple structure, simple production and processing and strong practicability.
Description
Technical field
The utility model relates to the bent axle of the bent axle of motor, particularly a kind of two-cylinder diesel.
Background technique
Along with the continuous development of diesel technology, power character, Economy, the machine travelling comfort of diesel engine are had higher requirement.Two-cylinder diesel is owing to little, the in light weight mating power that is more suitable for compact car of volume, but since the intrinsic vibration limiting of two-cylinder diesel its apply, simultaneously because the two-cylinder diesel exhaust is longer blanking time, long exhaust produces rhythmical impact to turbosupercharger blanking time, thereby cause on the one hand the unstable performance that influences diesel engine of supercharger speed, also the coupling and the reliability of two-cylinder diesel proposed very high requirement on the other hand.
The model utility content
The utility model provides a kind of bent axle of two-cylinder diesel, has not only reduced the vibration of two-cylinder diesel, and the exhaust that has solved than length produces rhythmical impact to turbosupercharger, reduction diesel engine noise, the travelling comfort of raising diesel engine blanking time.
The bent axle of the two-cylinder diesel that the utility model proposes reaches by following scheme:
A kind of bent axle of two-cylinder diesel, this bent axle is made of two rod journals, three main journals, four equilibrium blocks and rear end output flange spare global formation, and wherein two rod journals adopt 360 axles of writing music to arrange, have changed former 180 traditional degree angles and have arranged; Respectively there is an inclined oil hole of air to be communicated with between two rod journals before and after the bent axle and the adjacent main journal; Four equilibrium blocks are between each main journal and each rod journal, and described equilibrium block is a sector structure.
The bent axle of the two-cylinder diesel that the utility model provides, diesel engine speed can be reached more than 4000 rev/mins, satisfy the high rotating speed of diesel engine, the needs of high load, not only reduced the vibration of two-cylinder diesel, and the exhaust that has solved than length produces rhythmical impact to turbosupercharger blanking time, reduce the diesel engine noise, improve the travelling comfort of diesel engine, frictional force when having reduced the high speed rotating of diesel engine simultaneously, centrifugal force and tilting moment, can satisfy the high power of diesel engine, the requirement of high moment of torsion and high power per liter, it is simple in structure, production and processing is easy, practical.
Description of drawings
Fig. 1 is an example structure schematic representation of the present utility model.
Fig. 2 is an A-A sectional drawing among Fig. 1.
Embodiment
Describe below in conjunction with embodiment and accompanying drawing thereof, but protection domain of the present utility model is not limited thereto.
Shown in Fig. 1-2, the bent axle of the two-cylinder diesel that the utility model provides, mainly by preceding end journal 1, three main journals (2,4 before, during and after being positioned at, 6), two rod journals (3,5), four equilibrium blocks (9,10,11,13) and rear end output flange spare 7 global formations constitute, the angle between two rod journals is 360 degree.Wherein have inclined oil hole of air 8 to be communicated with between main journal 2 and the rod journal, main journal 6 and rod journal 5 have inclined oil hole of air 12 to be communicated with, and have improved the lubricating condition of bent axle high speed rotating, and diesel engine speed can be reached more than 4000 rev/mins; Four equilibrium blocks (9,10,11,13) between each main journal and each rod journal are sector structure.Angle between two rod journals is 360 degree, has not only reduced the vibration of two-cylinder diesel, and has solved long exhaust and blanking time turbosupercharger is produced rhythmical impact, reduces the diesel engine noise, improves the travelling comfort of diesel engine.
Claims (2)
1, a kind of bent axle of two-cylinder diesel, it is characterized in that: this bent axle is by two rod journals (3,5), also have three main journals (2,4,6), four equilibrium blocks (9,10,11,13) and rear end output flange spare (7) global formation constitute, wherein two rod journals adopt 360 axles of writing music to arrange, between two rod journals before and after the bent axle and the adjacent main journal inclined oil hole of air (8,12) connection is arranged respectively; Four equilibrium blocks are between each main journal and each rod journal.
2, the bent axle of two-cylinder diesel as claimed in claim 1 is characterized in that: described equilibrium block is a sector structure.
