Abstract
The utility model relates to an oil way external type diesel engine body, an engine body (1) is provided with a main bearing cover (2) and a rear bearing hole of cam shaft (3), the main bearing cover (2) is provided with a main bearing hole (4) and an oil pan (5) is provided on the bottom of engine body (1); the diesel engine body is characterized in that the outer wall of engine body (1) is provided with an external oil tube (6), an end of the external oil tube (6) is connected with the oil pan (5) and the other end is connected with the main bearing hole (4).
Description
Technical field
The utility model relates to a kind of diesel engine part, especially a kind of Oil Passage Externally-connected Diesel Engine Body.
Background technique
When carrying out oil lubricating by main bearing to diesel-engine body inside, along being drilled with the body oil duct in main bearing hole and the diametric body wall thickness of camshaft rear end cover bearing hole, lubricant oil is pressed into body camshaft rear end cover bearing hole by oil pump with the lubricant oil in the body oil sump, and then is pressed into main bearing hole realization lubricating main bearing and connecting rod bearing shell by the body oil duct.But, this structure is owing to be provided with the body oil duct between main bearing hole and camshaft rear end cover bearing hole, this part can produce stress and concentrates at body, in actual use, can on the body of offering body oil duct place, produce cracking, thereby whole machine body is scrapped.
Summary of the invention
Above-mentionedly to concentrate and to produce the deficiency that ftractures owing to stress offering body oil duct place in order to solve, the utility model provides a kind of Oil Passage Externally-connected Diesel Engine Body, this diesel-engine body is concentrated the problem that causes the body cracking thereby effectively avoided body because perforate causes stress when main bearing is lubricated.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Oil Passage Externally-connected Diesel Engine Body, body is provided with main bearing cap and camshaft rear end bearing hole, main bearing cap is provided with main bearing hole, be provided with oil sump at the body inner bottom part, the outer wall of described body is provided with external oil pipe, external oil pipe one end is communicated with oil sump, and the other end is communicated with main bearing hole.
Consider the compactedness and the aesthetic property of animal economy structure, further: described external oil pipe stretches into internal body and is communicated with main bearing hole from the side of main bearing cap.
The utility model is simple in structure, substitutes original body oil duct by adopting external oil pipe, efficiently solves the organism stress concentration problem, avoids the cracking of body, has prolonged the working life of body.

Fig. 1 is the structural representation of common diesel-engine body.
Fig. 2 is the utility model structural representation.
Among the figure: 1. body 2. main bearing cap 3. camshaft rear end bearing hole 4. main bearing holes 5. oil sumps 6. external oil pipe 7. body oil ducts
Embodiment
Common diesel-engine body as shown in Figure 1, has body 1, body 1 be provided with main bearing cap 2 and camshaft rear end bearing hole 3, main bearing cap 2 is provided with main bearing hole 4, be provided with oil sump 5 at body 1 inner bottom part, along being drilled with body oil duct 7 in main bearing hole 4 and camshaft rear end cover bearing hole 3 diametric body 1 wall thickness, by oil pump machine oil at first is pressed into camshaft rear end bearing hole 3 by oil sump 5, and then by body oil duct 7 machine oil is pressed into 4 pairs of main bearings of main bearing hole and is lubricated.
Make body 1 produce stress concentrates and causes cracking for fear of the existence of main bearing hole 4, now improve the oil duct oil-feed mode of body 1, concrete structure as shown in Figure 2, body oil duct 7 also is set on body 1 again, and replace external oil pipe 6, external oil pipe 6 is fixedly set in the outer wall of body 1, external oil pipe 6 one ends are communicated with oil sump 5, reach the outer wall of body 1, external oil pipe 6 stretches into body 1 inside along the outer wall stringing of body 1 from the side of main bearing cap 2, be communicated with main bearing hole 4, main bearing is lubricated, and lubricant oil passes back into oil sump 5 at last and carries out recycling.
Claims (2)
1. Oil Passage Externally-connected Diesel Engine Body, body (1) be provided with main bearing cap (2) and camshaft rear end bearing hole (3), main bearing cap (2) is provided with main bearing hole (4), be provided with oil sump (5) at body (1) inner bottom part, it is characterized in that: the outer wall of described body (1) is provided with external oil pipe (6), external oil pipe (6) one ends are communicated with oil sump (5), and the other end is communicated with main bearing hole (4).
2. Oil Passage Externally-connected Diesel Engine Body according to claim 1 is characterized in that: described external oil pipe (6) stretches into body (1) internal communication main bearing hole (4) from the side of main bearing cap (2).
