Description

Crankshaft oil seal base

Technical Field

The utility model relates to an automobile engine machinery especially relates to a crankshaft oil blanket base.

Background

The piston connecting rod group is a transmission part of an engine, mainly comprises a piston, a piston ring, a piston pin, a connecting rod and the like, and transmits the pressure of combustion gas to a crankshaft, so that the crankshaft rotates and outputs power. The assembly of the piston connecting rod group and the crankshaft is one of the key processes, and the process arrangement of the equipment of the assembly process and the subsequent treatment of the equipment of the assembly process are strictly required.

The published Chinese utility model patent has the publication number: CN206854267U, patent name: the utility model provides an engine connecting rod vibration dross removal mechanism, application date: 20170626, it discloses an engine connecting rod vibration dross removal mechanism, goes up the vibration chassis and links together through the location guide rail with vibration chassis down, go up and be equipped with the location dabber between vibration chassis and the vibration chassis down, the front on going up the vibration chassis is equipped with first moment of torsion rifle, second moment of torsion rifle, the first die clamping cylinder of connecting rod lid and connecting rod lid second die clamping cylinder, the reverse side on going up the vibration chassis is equipped with the second high-frequency vibration pump, the front on vibration chassis down is equipped with the first die clamping cylinder of connecting rod body, connecting rod body second die clamping cylinder and V-arrangement locating piece, the reverse side on vibration chassis is equipped with location dabber cylinder and first high-frequency vibration pump down. The utility model discloses thorough granule of having clear away the sectional remaining granule of connecting rod and surface adhesion has guaranteed the equipment of follow-up bent axle connecting rod, has reduceed the engine because of connecting rod fault probability, has improved work efficiency simultaneously, has reduced the intensity of labour at operation scene, has guaranteed the implementation effect of connecting rod slagging-off operation.

SUMMERY OF THE UTILITY MODEL

The utility model provides a crankshaft oil seal base seals cylinder bent axle opening part as the rotatory wear-resisting fulcrum of bent axle in the cylinder block.

The utility model provides a crankshaft oil seal base, which comprises a crankshaft oil seal base main body 1;

the crankshaft oil seal base body 1 is in an arch round cover shape, a bearing bush 2 is arranged in the hollow part, and a bottom beam 11 and a fixing hole 12 are arranged at the edge; the middle part of the crankshaft oil seal base body 1 is in a hollow prism lattice shape.

Preferably, the bottom beam 11 is strip-shaped.

Preferably, the fixing holes 12 are uniformly distributed on the edge of the crankshaft oil seal base main body 1 where the bottom beam 11 is not arranged.

Preferably, the bearing shell 2 is made of alloy steel material.

The utility model has the advantages that: the cleanness of a cylinder block lubricating system and the high-speed rotation stability of the crankshaft are ensured.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure, the position of the upper end of the main shaft,

1. a crankshaft oil seal base body; 11. a bottom beam; 12. a fixing hole; 2. bearing bushes;

Detailed Description

The present invention will now be described in detail with reference to the drawings, which are provided for illustrative and explanatory purposes only and should not be construed as limiting the scope of the present invention in any way.

In this embodiment, preferably, the bottom beam 11 is a strip.

In this embodiment, preferably, the fixing holes 12 are uniformly distributed on the edge of the crankshaft oil seal base main body 1 where the bottom beam 11 is not arranged.

In this embodiment, preferably, the bearing shell 2 is made of an alloy steel material. The wear resistance is ensured.

The surface precision of the bearing bush 2 is high, the self lightness is good, and the high-speed rotation of the main shaft can be supported. The surface clearance between the bearing bush and the oil seal seat is small. Can ensure that the outside dust and oil dirt can not enter the cylinder body, thereby ensuring the cleanness of the lubricant.

In a diesel engine, a crankshaft oil seal mount is mounted into a diesel block assembly. Its main function is sealed cylinder crankshaft opening part and is regarded as the bent axle and rotate wear-resisting fulcrum in the cylinder block, guarantees that cylinder block lubricating system is clean and bent axle high-speed rotational stability.

It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The above-mentioned embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
