Description
Technical Field
The utility model relates to a detachable zonulae occludens structure.
Background
At present, the connection between a flywheel and a crankshaft on an engine is generally positioned by a shaft diameter and a hole, and the flywheel and the crankshaft are connected and fastened by bolts. This requires corresponding connecting flanges on the crankshaft and flywheel. The disadvantages of the prior structure are that: the structure has the advantages that the manufacture is complex, the flange and the bolt hole are required to be designed on the crankshaft, the end face of the flange is perpendicular to the shaft diameter, and the precision is high. The flywheel and the crankshaft cannot be completely coaxial due to perpendicularity errors of the shaft diameter and the end surface, assembly and disassembly gaps and the like. This has an effect on the dynamic balance of the crankshaft itself.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the prior art, and providing a detachable tight connection structure which is convenient to connect.
The utility model provides a detachable closely connected structure, includes bent axle and flywheel, the bent axle on be equipped with the conical surface axle, the flywheel center is equipped with the taper hole that matches with the conical surface axle, is equipped with the oil filler point on the flywheel, is equipped with the oil duct that links to each other with the oil filler point in the flywheel, the oil duct also be linked together with the taper hole.
As a further improvement, the matching area of the taper hole and the taper shaft is more than or equal to 75 percent.
As a further improvement, the matching area of the taper hole and the taper shaft is less than or equal to 0.03 mm.
As a further improvement, the matching mode of the taper hole and the taper shaft is interference fit.
As a further improvement, the flywheel is provided with a plurality of mounting holes.
As a further improvement, the number of the mounting holes is 4-8.
Has the advantages that:
the utility model relates to an ingenious, simple structure, it is easier to make processing, and the installation with dismantle the convenience, connect firmly.
