Abstract
The utility model relates to a crankshaft, which comprises a main journal and a plurality of connecting rod journals distributed at intervals in the axial direction, wherein a crank is connected between the main journal and each connecting rod journal. The crank shaft is characterized in that the end surface of each crank connected with the main journal adopts an inclined surface or a cambered surface so as to be convenient for adjusting imbalance accurately during the processing and ensure rotation concentricity of adjustment; and oil filling holes are arranged on the cranks and each of the connecting rod journals respectively, the lubricating effect is good, and the probability of oil leakage is low. The crankshaft of the utility model has the advantages that the structure is simple, the processing is simple and convenient, the concentricity is good, the performance is reliable, the oil leakage can be prevented simultaneously and effectively, and the service life is prolonged; and the crankshaft has remarkable practical effect and is suitable for industrialized large-scale production.
Description
Technical field
The utility model relates to a kind of bent axle, particularly a kind of accessory bent axle that is used for high-pressure service pump, slurry pump.
Background technique
At present, the bent axle that is used for construction of road and bridge, well-digging, the contour press pump of cleaning pipeline, slurry pump is one of important accessory; Also there are some places not fully up to expectations in existing bent axle in application; Therefore, how to keep the concentricity of bent axle, accurately adjust and lay particular stress on, improve the reliability and stability of using, make its not easy oil leakage simultaneously, increase the service life; A kind of simple in structure, superior in quality bent axle is provided, promptly becomes one of these those skilled in the art problem anxious to be addressed.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, easy, significant bent axle of practical effect of processing is provided.
The technological scheme that the utility model adopted is for achieving the above object: a kind of bent axle, this bent axle comprise the rod journal that main journal and a plurality of axially spaced-apart distribute, and are provided with crank between main journal and each rod journal and link to each other; It is characterized in that the crank end face that is connected with main journal is inclined-plane or cambered surface; Be respectively equipped with oil hole on described crank and each rod journal.
The beneficial effects of the utility model are: the utility model is simple in structure, processes easyly, and concentricity is good, and reliable performance can effectively prevent from leakage of oil to increase the service life simultaneously; This bent axle practical effect highly significant, and be suitable for industrialized production.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1 main journal, 2 cranks, 3 rod journals, 4 oil holes.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment that foundation the utility model provides:
Referring to Fig. 1, a kind of bent axle; This bent axle comprises the rod journal 3 that main journal 1 and a plurality of axially spaced-apart distribute, and is provided with crank 2 between main journal 1 and each rod journal 3 and links to each other; It is characterized in that crank 2 end faces that are connected with main journal 1 are inclined-plane or cambered surface, be convenient to add accurately adjust man-hour and lay particular stress on, guarantee to regulate the rotation concentricity; Be respectively equipped with oil hole 4, high lubricating effect and not easy oil leakage on described crank 2 and each rod journal 3.
Above-mentioned with reference to embodiment to the detailed description that this bent axle carries out, be illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
