Abstract
The utility model relates to the technical field of a machine, and in particular relates to a structure for repairing a crankshaft bearing. The structure comprises a back bearing and a sleeve, wherein the sleeve is nested in a round hole at the right end of the back bearing. Compared with the prior art, according to the structure, a sleeve structure is additionally arranged in the back bearing, so that the sleeve can be replaced when being worn after the sleeve is used for a long period of time, thus the phenomenon that the whole crankshaft of an engine is scrapped is avoided, and the reutilization ratio of the crankshaft of the engine is further improved.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of repair structure of crankshaft bearing.
Background technique
The engine crankshaft rear bearing generally is connected with jack shaft.After long-term the use, the phenomenon of circle or mechanical bump injury can appear losing in the engine crankshaft rear bearing, thereby causes that engine crankshaft integral body is scrapped, the utilization ratio again of engine crankshaft is low.Therefore, the design a kind of can improve engine crankshaft again the repair structure of the crankshaft bearing of utilization ratio be vital.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes existing technology, provides a kind of and can improve the engine crankshaft repair structure of the crankshaft bearing of utilization ratio again.
In order to achieve the above object, the utility model comprises rear bearing and sleeve, it is characterized in that: the embedded sleeve that is with of the right-hand member circular hole of rear bearing.
The utility model is compared with existing technology, in rear bearing, has increased tube-in-tube structure, and sleeve can be replaced when wear phenomenon takes place long-term the use, thereby the phenomenon of having avoided engine crankshaft integral body to scrap has also improved the utilization ratio again of engine crankshaft.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the side view of the utility model structural representation.
Referring to Fig. 1 and Fig. 2,1 is rear bearing; 2 is sleeve.
Embodiment
Combine accompanying drawing that the utility model is done further describes at present.
Referring to Fig. 1 and Fig. 2, the utility model comprises rear bearing and sleeve.Be provided with sleeve 2 in the right-hand member circular hole of rear bearing 1.
The utility model is put into rear bearing 1 on the lathe together with sleeve 2 sleeve 2 is carried out turning when sleeve 2 uses when wear phenomenon takes place long-term.After sleeve 2 is clean by turning fully, new sleeve 2 is nested in the rear bearing 1 through press, can recover the whole use of engine crankshaft, thereby the phenomenon of having avoided engine crankshaft integral body to scrap has also improved the utilization ratio again of engine crankshaft.
