Abstract
The utility model discloses a gear disassembling tool for a fuel oil pump, wherein the gear disassembling tool is used for disassembling the gear of the fuel oil pump gear of an engine. A fixed plate is provided with a connecting hole and a cylindrical pin; and a screw nail penetrates through the connecting hole of the fixed plate, so that a sector gear blade is fixed on a plate. When the gear disassembling tool is in use, the fixed plate is fixed on the fuel oil pump through four screw nails, and three sector gears which are meshed with a front gear of the fuel oil pump are fixed on the plate through the four screw nails simultaneously, so that the three sector gears are mutually meshed with the front gear of the fuel oil pump; the plate is positioned on the fixed plate through the cylindrical pin for preventing the rotation of the gears; a sleeve is sleeved on a gear fixing nut; and the nut is disassembled by using a wrench, so that the front gear of the fuel oil pump is disassembled. The gear disassembling tool disclosed by the utility model has the characteristics of effectively preventing gear damage owing to the fact that pressing equipment, such as flat pliers, presses the gear, and furthest protecting the engine parts in the process of easily drawing out the gear.
Description
Technical field
The utility model relates to technical field of tools, is a kind of specific purpose tool of dismantling the engine fuel pump gear specifically.
Background technology
At present, the dismounting of engine fuel injection pump front gear all is with the most original mode, pulls down fuel pump (band front gear), and fuel oil pump assembly is moved to the next door, pushes down gear with flat-nose pliers or other compression apparatus, prevents that gear and nut from rotating together.Utilize spanner or other instrument dismounting lower nut, take off gear again.But,, gear is had very big damage owing to be to press gear with compression apparatus such as flat-nose pliers.
Summary of the invention
In order to overcome the deficiency that existing method dismounting fuel pump front gear causes damage parts; The goal of the invention of the utility model is to provide a kind of fuel pump gear extracting tool; Gear can not only be easily split out with realization, and the purpose of engine fittings can be at utmost protected.
For realizing above-mentioned purpose, the fixed head of the utility model has connecting hole and straight pin, and it is fixing onboard with the sector gear sheet that screw passes the connecting hole of fixed head.
During use, with four screws fixed head is fixed on the fuel pump, four screws are fixing onboard with three sector gears that are meshed with the fuel pump front gear simultaneously; Sector gear and fuel pump front gear intermesh; Straight pin is positioned at plate on the fixed head, prevents that gear from rotating, again with jacket casing on the gear hold-down nut; Utilize spanner to unload lower nut, and then pull down the fuel pump front gear.
The utility model compared with prior art can effectively be avoided pressing gear and to the damage that gear causes, can when easily extracting gear, farthest protecting engine components with compression apparatus such as flat-nose pliers.
Description of drawings
Fig. 1 is the three-dimensional sketch of the utility model.
The specific embodiment
As shown in Figure 1, with four screws 1 fixed head 2 is fixed on the fuel pump, be fixed on three sector gear sheets 5 that are meshed with the fuel pump front gear on the plate 4 with screw 1 simultaneously; Plate 4 is positioned on the fixed head 2 through straight pin 3; Avoiding plate 4 to rotate, thereby prevent the rotation of fuel pump front gear, again with jacket casing on the hold-down nut of fuel pump front gear; Utilize spanner to unload lower nut, pull down the fuel pump front gear.
