Abstract
The utility model relates to a component of a diesel engine, in particular to a cylinder body the diesel engine. An upper counter-bore, an upper bolt hole, a lower counter-bore and a lower bolt hole which are used to fixedly connect an upper cylinder head, a main bearing cap and the cylinder body are respectively opened on the top plane and the bottom plane of the cylinder body, wherein the depth of the upper counter-bore is 35-40mm. According to finite element analysis result and actual measurement condition, the utility model improves the deformation of a bolt counter-bore under the forced condition, has small influence for the deformation of a cylinder jacket of the cylinder, and improves the unevenness of the top plane of the cylinder body through deepening the upper counter-bore.
Description
Technical field
The utility model relates to a kind of diesel engine part, especially a kind of diesel engine cylinder block.
Background technique
For diesel engine cylinder block, will fixedly connected by bolt with main bearing cap with upper cylinder cover respectively with the bottom plane in the Qi Ding plane, and junction surface is provided with wears the counterbore and the bolt hole of twisting bolt, and bolt passes counterbore and bolt hole by being threaded.But counterbore and bolt hole on the plane, top of common cylinder body get close to the cylinder liner that is arranged on cylinder interior, as shown in Figure 1, because counterbore is more shallow, when engine operation, bolt hole and bolt joint deform the cylinder liner counterbore under the effect of bolt pretightening and combustion gas explosive force, thereby cause the distortion of dry liner, cause the piston cisco unity malfunction, sealability descends, the discharging variation.
Summary of the invention
In order to overcome above-mentioned because the mounting point of counterbore and bolt hole concerns, cylinder liner is deformed, influence the normal operation of diesel engine, the utility model provides a kind of running-deep-hole diesel engine cylinder block.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of running-deep-hole diesel engine cylinder block, on the plane, top of cylinder body and bottom plane, offer respectively to be used to wear and twist bolt upper cylinder cover, the last counterbore that main bearing cap is fixedlyed connected with cylinder body, upper bolt hole and lower counterbore and following bolt hole, take into full account the rationality that counterbore and following bolt hole junction surface on cylinder body are provided with the position, guaranteeing that the loam cake cylinder can be by bolt with when cylinder body firmly be connected, counterbore in the intensification, the connection part that makes bolt and bolt hole is as far as possible away from cylinder liner, and described upward counterbore depth H is 35～40mm.
In order to make counterbore and upper bolt hole reach best position, further: described upward counterbore depth H is 38mm.
The utility model from The results and actual measurement situation, has improved the amount of deformation of bolt hole under stressing conditions by deepen going up counterbore, and is very little to the influence of the cylinder liner deformation of cylinder, and improved the Roughness on plane, cylinder body top.
Description of drawings
The diesel engine cylinder block structural representation that Fig. 1 is common.
Fig. 2 is the utility model structural representation.
Among the figure: 1. cylinder body 2. pushes up 7. times bolts hole of counterbore 5. upper bolt holes, 6. lower counterbore on 3. bottom planes 4., plane
Embodiment
A kind of running-deep-hole diesel engine cylinder block as shown in Figure 2, on the plane, top 2 of cylinder body 1 and bottom plane 3, offer respectively be used to wear twist that bolt fixedlys connected upper cylinder cover, main bearing cap with cylinder body 1 on counterbore 4, upper bolt hole 5 and lower counterbore 6 and following bolt hole 7, last counterbore 4 depth H are 35～40mm, preferred depth H=38mm.
Claims (2)
1. running-deep-hole diesel engine cylinder block, offer respectively to be used to wear on the plane, top (2) of cylinder body (1) and bottom plane (3) and twist bolt is fixedlyed connected upper cylinder cover, main bearing cap with cylinder body (1) last counterbore (4), upper bolt hole (5) and lower counterbore (6) and following bolt hole (7), it is characterized in that: counterbore (4) depth H is 35～40mm on described.
2. running-deep-hole diesel engine cylinder block according to claim 1 is characterized in that: described upward counterbore (4) depth H is 38mm.
