Abstract
The utility model relates to a lubricating oil nozzle for a lubrication mechanism of an engine. The lubricating oil nozzle is rod-shaped, one end of the lubricating oil nozzle is a hexagon head, and the other end of the lubricating oil nozzle is a screw rod. A circular groove is formed in the rod body close to the screw rod, and a radial oil channel is formed in the rod body where the circular groove is located in the radial direction of the rod body. And an axial oil channel is formed in the screw rod in an axial direction, the axial oil channel is communicated with the radial oil channel, and the diameter of the axial oil channel is smaller than the diameter of the radial oil channel. The lubricating oil nozzle for the lubrication mechanism of the engine is not prone to dropping and convenient to install and maintain when used. Due to the fact that the diameter of the axial oil channel is smaller than the diameter of the radial oil channel, the pressure of lubricating oil can be increased sharply when the lubricating oil enters the axial oil channel from the radial oil channel, and the lubricating oil is sprayed on components to be lubricated. The diameter of a processing hole is bigger than the diameter of the axial oil channel, and the process difficulty of the axial oil channel is greatly reduced.
Description
Technical field
The utility model belongs to technical field of internal combustion engines, is specifically related to the lubricating fuel spray nozzle structure for engine lubrication mechanism.
Background technique
During engine operation, a lot of component are all being done the high speed relative movement, if these component surfaces are not lubricated, between them strong friction will occur.Some component can lubricate by lubricating oil path, and some component can not lubricate by lubricating oil path, and these component just need oil nozzle to lubricate.Traditional oil nozzle all is some tiny metal winding pipes, directly is fitted on cylinder body or other component.This oil nozzle all needs special instrument when installing, also come off easily in the process of using, and damages other part.Owing to need special instrument, so also be not easy to maintenance, the jet pressure of machine oil is also little.
Summary of the invention
For above problem, the lubricating fuel spray nozzle that is used for engine lubrication mechanism that the utility model provides a kind of difficult drop-off, is easy to install and maintain.
The lubricating fuel spray nozzle that is used for engine lubrication mechanism is shaft-like, and an end is hexagon head, and the other end is screw rod, is provided with circular groove with the shaft of screw rod adjacent, and the shaft at circular groove place directly upwards offers radial direction oil; Offer axial oil duct on the described screw rod, axially oil duct and radial direction oil connect, and the diameter of axial oil duct is less than the diameter of radial direction oil.
The external port of described axial oil duct is auxiliary hole, and the auxiliary hole diameter is greater than axial oil duct diameter.
Difficult drop-off when the utility model is installed and used, and installation and maintenance are convenient.Because axially the diameter of oil duct is less than the diameter of radial direction oil, so pressure can become suddenly large when machine oil entered axial oil duct by radial direction oil, being injected in needs on the lubricated parts.The diameter of auxiliary hole has reduced the difficulty of processing of axial oil duct greatly greater than the diameter of axial oil duct.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is use phase diagram of the present utility model.
Sequence number among the upper figure: hexagon head 10, screw rod 11, circular groove 12, radial direction oil 13, axial oil duct 14, auxiliary hole 15, fuel pump bearing 20, machine oil oil duct 21, pad 30.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, the lubricating fuel spray nozzle that is used for engine lubrication mechanism is shaft-like, and an end is hexagon head 10, and the other end is screw rod 11, and offers circular groove 12 on the shaft of screw rod 11 adjacents, and the shaft at circular groove 12 places directly upwards offers radial direction oil 13; Offer axial oil duct 14 on the screw rod 11, axially oil duct 14 connects with radial direction oil 13, and the diameter D2 of axial oil duct 14 is less than the diameter D1 of radial direction oil 13.Axially the external port of oil duct 14 is auxiliary hole 15, and auxiliary hole 15 diameter D3 see Fig. 3 greater than the diameter D2 of axial oil duct 14.
Referring to Fig. 4, during use, lubricating fuel spray nozzle is installed on the fuel pump bearing 20, seals by pad 30 between oil nozzle and the fuel pump bearing.Machine oil is entered in the circular groove 12 by machine oil oil duct 21, enter axial oil duct 14 through radial direction oil 13 again, because the diameter of radial direction oil 13 is larger than the diameter of axial oil duct 14, the cross section diminished suddenly when machine oil was flowed through axial oil duct 14, it is large that pressure becomes, and machine oil will spray to high pressure fuel pump.
