Abstract
The utility model relates to the technical filed of high-pressure oil pumps, in particular to a high-pressure oil pump, which comprises an oil pump body and a plunger bushing sheathed with the oil pump body, wherein the plunger bushing is internally matched with a plunger, and the head part of the plunger is arranged into a T-shaped head, and is clamped with a plunger base. The high-pressure oil pump also comprises a variable oil injection timing setting mechanism which is formed by a plunger bushing with an external thread, a variable oil injection timing gear ring meshed and connected with the plunger bushing with the external thread, and the variable timing rack inserted and connected with the variable oil injection timing gear ring. Since the variable oil injection timing setting mechanism is additionally arranged on the high-pressure pump, the utility model can timely inject oil, avoids unnecessary waste, reduces the wear among parts of the pump body, saves cost, and improves the service life of the high-pressure pump.
Description
Technical field
The utility model belongs to the high pressure oil pump technical field, is specifically related to the high pressure oil pump that a kind of belt variable injection timing sets up an organization.
Background technique
At present, the high pressure oil pump of use is at motor rapidly the time, and all cylinders are whole oil jetting combustions still, and like this, one causes the waste of fuel oil and produces the pollution of more waste gas to environment, in addition, makes that also the wearing and tearing of each parts are accelerated in the oil pump, reduces user cost.Therefore, the high pressure oil pressure of a kind of regularly oil spout of design seems and is even more important.
The model utility content
At the above-mentioned problems in the prior art, the high pressure oil pump that provides a kind of belt variable injection timing to set up an organization is provided the purpose of this utility model.
Described a kind of high pressure oil pump, comprise pump body, the plunger guide bush that is connected with the pump body socket, be equipped with plunger in the described plunger guide bush, the head of plunger is set to cross head, be connected with the plunger mat clamping, it is characterized in that described high pressure oil pump comprises that also a variable injection timing sets up an organization.
Described a kind of high pressure oil pump, it is characterized in that described variable injection timing sets up an organization by being with externally threaded plunger guide bush, with the variable injection timing gear ring that the plunger guide bush outside thread is connected with a joggle, reach variable injection timing tooth bar formation with the socket connection of variable injection timing gear ring.
Described a kind of high pressure oil pump is characterized in that described plunger guide bush outside thread is two, and another outside thread and throttle gear ring are connected with a joggle, throttle gear ring and the socket connection of throttle tooth bar.
Described a kind of high pressure oil pump is characterized in that also disposing between described pump body and the plunger guide bush set screw that both are fixed.
Above-mentioned a kind of high pressure oil pump, comprise pump body, the plunger guide bush that is connected with the pump body socket, be equipped with plunger in the described plunger guide bush, the head of plunger is set to cross head, is connected with the plunger mat clamping, and described high pressure oil pump also comprises by being with externally threaded plunger guide bush, the variable injection timing gear ring that is connected with a joggle with the plunger guide bush outside thread, and set up an organization with variable injection timing that the variable injection timing tooth bar of variable injection timing gear ring socket connection constitutes.The utility model sets up an organization by add a variable injection timing on high pressure oil pump, and unnecessary waste is avoided in regularly oil spout, reduces the wearing and tearing between the pump housing parts, saves cost, uses the working life of high pressure oil pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-pump body, 2-plunger guide bush, 3-set screw, the variable injection timing tooth bar of 4-, 5-throttle tooth bar, 6-plunger mat, 7-throttle gear ring, the variable injection timing gear ring of 8-, 9-plunger.
Embodiment
Below in conjunction with Figure of description and embodiment the utility model is further described:
As shown in Figure 1, a kind of high pressure oil pump, comprise pump body 1, the plunger guide bush 2 that is connected with pump body 1 socket, be equipped with plunger 9 in the described plunger guide bush 2, the head of plunger 9 is set to cross head, be connected with plunger mat 6 clampings, described high pressure oil pump comprises that also a variable injection timing sets up an organization, described variable injection timing sets up an organization by being with externally threaded plunger guide bush 2, with the variable injection timing gear ring 8 that plunger guide bush 2 outside threads are connected with a joggle, reach variable injection timing tooth bar 4 formations with variable injection timing gear ring 8 socket connections.
Described plunger guide bush 2 outside threads are two, and another outside thread and throttle gear ring 7 are connected with a joggle, throttle gear ring 8 and 5 socket connections of throttle tooth bar.Also dispose the set screw 3 that both are fixed between described pump body 1 and the plunger guide bush 2.
As shown in Figure 1, should be earlier during assembling plunger guide bush 2 pump body 1 of packing into, locating slot above the plunger guide bush 2 is alignd with positioning screw hole on the pump body 1 and adjust on it and be with set screw 3 again behind height on the plane and pump body 1.This set screw 3 can only make plunger guide bush 2 circumferencial directions location, axially can not locate, and plunger guide bush 2 will move up and down when variable injection timing set up an organization work.Plunger guide bush is moved variable injection timing tooth bar 4 to position that variable injection timing gear ring 8 has salient point behind 2 location again, and the head alignment post plug sleeve 2 externally threaded heads of variable injection timing gear ring 8 internal threads are packed into to get final product.Throttle gear ring 7 is installed at last, and the two sides that throttle gear ring 7 positive and negative direction can pack into and have is markedness all, mark of one side, another side has two marks, that face of a mark should be outwardly with throttle tooth bar 5 on mark aim to pack into and get final product.
