Abstract
The utility model relates to a back shroud and oil pan of middle-size and small-size engine, its characterized in that, along interior limit, outside and bolt hole on the bottom surface of back shroud and oil pan, a week all has the section to be triangle-shaped's oily warp that hinders, and it has characteristics such as simple manufacture, low cost, light in weight, difficult oil leak and assembly are easy.
Description
The utility model relates to a kind of middle-size and small-size motor back shroud and oil sump.
The back shroud of existing middle-size and small-size machine and oil sump are made by cast iron and cold-reduced sheet, and this back shroud and oil sump cost are higher, the also tired lock of Heavy Weight, assembling, oil leakage phenomenon can occur when using in addition.
The purpose of this utility model is to adopt a kind of novel structure and material, thereby has overcome the back shroud and the deficiencies such as oil sump cost height, Heavy Weight, easy oil leakage and the tired lock of assembling of existing middle-size and small-size motor.
The back shroud of this middle-size and small-size motor and oil sump are leg-of-mutton oil resistance warp at upper edge, bottom surface inner edge, outside and along section is all arranged in one week of bolt hole, and the height of oil resistance warp is 0.2-0.4mm.
The back shroud of this middle-size and small-size motor and oil sump are to be made by Reinforced Nylon or plastics.
Below in conjunction with accompanying drawing structure of the present utility model is done the detail explanation.
Fig. 1 is a schematic representation of the present utility model
Fig. 2 is the A-A sectional drawing
In the accompanying drawings, the back shroud or the oil sump of the middle-size and small-size motor of 8 expressions, it is to be made by Reinforced Nylon or plastics, because the other parts structure does not make improvements, therefore among the figure just not detail draw, at the bottom surface of back shroud or oil sump 81 upper edge inner edge 6, the outside 7 and all have in one week of bolt hole section be leg-of-mutton in oil resistance through 2, outer oil resistance through 3 and oil resistance through 4, wherein interior oil resistance is through 2, outer oil resistance through 3 and oil resistance be 0.2-0.4mm through 4 high h, during assembling, back shroud is connected with engine block by bolt with oil sump 8, when bolt tightens, interior oil resistance on the bottom surface 1 of back shroud or oil sump 8 is through 2, outer oil resistance just is in the same place with engine block is tightly identical through 4 with oil resistance through 3, need not add one deck mat again, oil resistance 1 has limit on leakage of oil through 3 oil that stoped engine body from the bottom surface with outer oil resistance through 2 like this, interior oil resistance through 2 and oil resistance also stoped oily from the bolt hole leakage of oil through 4; When engine operation, back shroud and oil sump 8 has slight expansion owing to be heated, like this can with motor show consideration for tighter, the interior oil of body more can't spill.
The utility model has the advantages that manufacture craft is simple, with low cost, have higher economic benefit.
Claims (2)
1, a kind of back shroud of middle-size and small-size motor and oil sump, it is characterized in that back shroud or oil sump 8 all have in bottom surface 1 upper edge inner edge 6, outside 7 and 5 one weeks of bolt hole section be leg-of-mutton in oil resistance through 2, outer oil resistance through 3 and oil resistance through 4, interior oil resistance through 2, outer oil resistance through 3 and oil resistance be 0.2-0.4mm through 4 high h.
2, back shroud according to claim 1 and oil sump is characterized in that back shroud and oil sump 8 are to be made by Reinforced Nylon and plastics.
