Description
Technical Field
The utility model relates to a technical field of engine, more specifically say, the utility model relates to an oil blanket mounting structure behind bent axle.
Background
FIGS. 1-2 show a prior art rear oil seal mounting structure of a crankshaft, wherein 1 is a cylinder block; 2 is a bolt; 3 is a rear oil seal seat; 4 is crankshaft rear oil seal; and 5 is a crankshaft. Wherein, the crankshaft rear oil seal 4 is pressed on the rear oil seal seat 3 in an interference fit manner, and the rear oil seal seat 3 is arranged on the cylinder body through the bolt 2. The above-described mounting structure has the following problems.
1. The number of parts is large, and the management cost is increased.
2. High production cost and more production and assembly processes.
3. And the rear oil seal seat needs to be coated with glue during installation, and if the coating of the sealant is not uniform, the risk of untight sealing exists.
SUMMERY OF THE UTILITY MODEL
For the above-mentioned technical problem who exists among the solution prior art, the utility model aims to provide an oil blanket mounting structure behind bent axle.
The utility model discloses an oil blanket mounting structure behind bent axle, its characterized in that: the oil-gas separator comprises a cylinder body, an oil pan, a crankshaft and a crankshaft rear oil seal; the cylinder body with the adjacent setting of oil pan, and the bent axle sets up the cylinder body with between the oil pan, the rear end casting of cylinder body and oil pan forms back oil blanket installation boss processing has back oil blanket mounting groove in the back oil blanket installation boss, the bent axle rear flange of bent axle is located in the back oil blanket mounting groove, oil blanket interference pressure equipment is in behind the bent axle the outer wall of flange with between the inner wall of back oil blanket mounting groove.
Wherein, back oil blanket installation boss is cylindrical.
Compared with the prior art, the utility model discloses an oil blanket mounting structure behind bent axle has following beneficial effect:
1. and a rear oil seal seat and a bolt are eliminated, so that the management cost is reduced.
2. The production cost is reduced, and the production and assembly procedures are reduced.
3. The risk of untight sealing of the rear end of the engine is reduced.

Detailed Description
It is right to combine specific embodiment below the utility model discloses a grease seal mounting structure behind bent axle does further explanation to help technical staff in this field to be right the utility model discloses a there is more complete, accurate and deep understanding in utility model design, technical scheme.
Example 1
As shown in fig. 3 to 5, the crankshaft rear oil seal mounting structure of the present embodiment includes a cylinder block 6, an oil pan 9, a crankshaft 8, and a crankshaft rear oil seal 7. The cylinder body 6 with the oil pan 9 is close to the setting, and bent axle 8 sets up the cylinder body 6 with between the oil pan 9, oil blanket installation boss 12 after the rear end casting of cylinder body 6 and oil pan 9 forms, back oil blanket installation boss 12 is cylindrical processing has back oil blanket mounting groove 11 in the back oil blanket installation boss 12, bent axle rear flange 10 of bent axle 8 is located in back oil blanket mounting groove 11, 7 interference pressure equipment of oil blanket behind the bent axle are in the outer wall of bent axle rear flange 10 with between the inner wall of back oil blanket mounting groove 11.
The rear oil seal mounting structure of the embodiment cancels the rear oil seal seat and the bolt, reduces the production cost and the management cost, reduces the production and assembly processes, and reduces the risk of untight sealing of the rear end of the engine.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
