An oil pump chain guide rail arrangement structure comprises an oil pump chain guide rail 1, a torsion spring 2, an air cylinder body 3, an oil pump chain 4 and a guide rail fixing screw 5; the lower end of the cylinder body 3 is provided with a cylinder body limiting groove 6, the cylinder body 3 is connected with a mounting seat of an oil pump chain guide rail 1 through a guide rail fixing screw 5, and an oil pump chain 4 is arranged on the oil pump chain guide rail 1; the outer side of the mounting seat of the oil pump chain guide rail 1 is sleeved with a torsion spring 2, the torsion spring 2 is arranged at the front end of the oil pump chain guide rail 1, the A end of the torsion spring 2 is clamped with the front side surface of the oil pump chain guide rail 1, and the B end of the torsion spring 2 is clamped with the cylinder block limiting groove 6 of the cylinder block 3.
The center of the end A of the torsion spring 2 and the center surface of the oil pump chain guide rail 1 are positioned on the same horizontal plane, so that the chain system can run stably without side force interference.
The end B of the torsion spring 2 bends twice and is matched with the limit groove 6 of the cylinder body 3 to realize axial limit of the torsion spring 2.
According to the invention, the occupation of the axial space of the chain system is reduced to the greatest extent by optimizing the positions and the shapes of the oil pump chain guide rail, the torsion spring and the limiting groove, and the chain system is ensured to run stably, so that a larger space is provided for assembly of other structures. The guide rail body is of a plastic structure, and is matched with the limiting structures of the guide rail, the torsion spring and the cylinder body, so that the axial limiting of the guide rail can be realized, the chain is prevented from being separated, and the stable operation of the oil pump chain is realized.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
