Abstract
The utility model relates to a diesel engine part, in particular to a bent axle balance block of a diesel engine, wherein the outer edge of the bent axle balance block is a circular arc which takes the axial center of a main axle as the circle center, the distance e between the crossing point of extension lines on the shoulder portions of the bent axle balance block and the axial center of the main axle is 12mm-18mm, the included angle alpha is 120 degrees to 160 degrees. Through the design, the bent axle balance block is increased, the balance of an entire machine is satisfied at the premise that the self-balance of each bellcrank is guaranteed, the result through calculating static and dynamic state simulating analysis balance shows that the diesel engine can greatly improve the balance performance of an entire machine after improved.
Description
Technical field
The utility model relates to a kind of diesel engine part, especially the crankshaft of diesel engine equilibrium block.
Background technique
Present crankshaft counter balance is as shown in Figure 2 less, the percentage of balance rotating moment of inertia is less, can only carry out balance with the matter footpath square that increases belt pulley, but owing to adopt the overall balance method when carrying out balance with belt pulley, at the inner additional bending moment that produces of bent axle, be unfavorable for the proper functioning of bearing shell.Big many of the matter of the matter of belt pulley footpath moment ratio flywheel footpath square in addition, it is inconsistent that the square center of getting of the moment that belt pulley and flywheel constitute and rotatory inertia moment and one-level reciprocal inertia force square are got the square central position, so this design is unreasonable, in the balance rotating moment of inertia with when shifting one-level reciprocal inertia force square, produced additional moment, this moment has been destroyed original balance.
Summary of the invention
In order to better meet the balance quality of this machine, the utility model provides a kind of crankshaft of diesel engine equilibrium block.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of crankshaft of diesel engine equilibrium block, the crankshaft counter balance outer rim is to be the circular arc in the center of circle with the spindle axis, the intersection point of the line stretcher of the shoulder that crankshaft counterbalance is fast and spindle axis be that 12mm～18mm, angle are 120 °～160 ° of α apart from e.
Further optimize, the intersection point of the line stretcher of the shoulder that crankshaft counterbalance is fast and spindle axis be that 15.18mm, angle α are 140 ° apart from e.
The beneficial effects of the utility model are: increased crankshaft counter balance by above-mentioned design, under the prerequisite that guarantees each crank throw self balance, satisfy the balance of complete machine, show, can well improve the balance quality of complete machine after the improvement by calculating and result quiet, that dynamic simulation is analyzed balance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of former crankshaft counter balance.
Among the figure: 1. outer rim, 2. shoulder, 3. spindle axis.
Embodiment
A kind of crankshaft of diesel engine equilibrium block as shown in Figure 1, the radius of crankshaft counter balance outer rim 1 are that R is 77mm, and the center of circle is a spindle axis 3, and the intersection point of the line stretcher of the shoulder back of the body 2 that crankshaft counterbalance is fast and the distance of spindle axis 3 are that 15.13mm, angle are that α is 140 ° for e.Show by calculating and result quiet, that dynamic simulation is analyzed balance, can well improve the balance quality of complete machine after the improvement.
