Abstract
The utility model relates to a shaft end sealing structure of an engine crankshaft, which belongs to the field of engines. Sealing steel jackets are fixedly arranged at shaft necks at both ends of a crankshaft, and framework oil seals are assembled outside the sealing steel jackets; the structure has good sealing and wear-resistant functions to the neck parts at the both ends of the crankshaft, thereby the abrasion to the neck of the crankshaft is avoided, and the utility model has the characteristics of simple structure, long service life of the crankshaft, simple and convenient maintenance, good sealing effect and low use cost.
Description
Technical field
The utility model belongs to motor, relates generally to the engine crankshaft sealing structure of shaft end.
Background technique
At present, all directly equipped contiguously outside framework oil seals on the crankshaft two end axle journal of various explosive motors, to reach the shaft end seal effect.In actual job, outside framework oil seal very easily grinds groove with bent axle axle head neck, produces oil leakage fault, after this moment, unique solution was disassembled motor exactly, crankshaft journal is carried out overhauls such as built-up welding, correct grinding, complex process, cost height, to reduce bent axle working life be its distinct issues.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, and design provides a kind of engine crankshaft sealing structure of shaft end of new structure, reaches to prolong bent axle working life, convenient for maintaining, assurance sealing effect, reduce the purpose of maintenance cost.
Basic design of the present utility model is, the engine crankshaft sealing structure of shaft end comprises bent axle and outside framework oil seal, fixed installation sealing steel bushing on the crankshaft two end collar, and outside framework oil seal is fitted on the sealing steel bushing outside.
The utility model is simple in structure, and good sealing effect has protective action well to bent axle axle head neck, the bent axle long service life, and convenience easy to repair, with low cost.
Description of drawings
Accompanying drawing is an engine crankshaft sealing structure of shaft end schematic representation.
Piece number explanation among the figure:
1, outside framework oil seal, 2, sealing steel bushing, 3, bent axle.
Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The engine crankshaft sealing structure of shaft end comprises bent axle 3 and outside framework oil seal 1, fixed installation sealing steel bushing 2 on bent axle 3 two end axles necks, and outside framework oil seal 1 is fitted on sealing steel bushing 2 outsides.
During operation, the bent axle 3 of rotation drives with its all-in-one-piece sealing steel bushing 2 and rotates in the lump, and with respect to outside framework oil seal 1 motion, outside framework oil seal 1 plays the collar seal action to sealing steel bushing 2 in outside framework oil seal 1 hole.When generation sealing steel bushing 2 grinds groove and outside framework oil seal 1 damage, only need the sealing steel bushing 2 after wearing and tearing is pulled down from the axle head neck of bent axle 3, the sealing steel bushing 2 and the outside framework oil seal 1 that more renew get final product, and bent axle axle head neck is not subjected to any damage.
Claims (1)
1, a kind of engine crankshaft sealing structure of shaft end comprises bent axle (3) and outside framework oil seal (1), it is characterized in that fixed installation sealing steel bushing (2) on bent axle (3) two end axles neck, and outside framework oil seal (1) is fitted on sealing steel bushing (2) outside.
