Abstract
The application provides a round pin hub connection structure belongs to mechanical connection technical field, round pin hub connection structure include: a double-lug structure; the single-lug structure extends into the double-lug structure and is connected with the double-lug structure; the pin shaft is provided with a first hole groove extending along the axis of the pin shaft and a second hole groove communicated with the first hole groove and extending in the radial direction, lubricating oil is injected into the first hole groove, so that the lubricating oil flows out of the second hole groove, and a lubricating oil film is formed on a matching surface between the pin shaft and the single lug structure. The pin shaft connecting structure can solve the abrasion problem of pin shaft connection in the prior art, avoids connection failure caused by abrasion, and saves labor, economy and time cost.
Description
Technical Field
The application belongs to the technical field of mechanical connection, in particular to a pin shaft connecting structure.
Background
A pin connection is a form of construction commonly used between parts having some relative angular movement to form a hinge.
At present, generally adopt round pin hub connection in the field of aviation, when taking place angular motion between two parts of connecting, even amplitude is very little, nevertheless because load is very high, take place sliding friction between the excircle fitting surface of round pin axle and the interior round fit of connected part to produce the abrasive grain, because the grit that the friction formed can't discharge, its grinding effect further aggravates wearing and tearing, can lead to connecting failure after the certain time, have the potential safety hazard, and repair or change has increased manual work, economy and time cost.
Disclosure of Invention
It is an object of the present application to provide a pin connection structure to solve or mitigate at least one problem of the background art.
The technical scheme of the application is as follows: a pin connecting structure, comprising:
a double-lug structure;
the single-lug structure extends into the double-lug structure and is connected with the double-lug structure;
the pin shaft is provided with a first hole groove extending along the axis of the pin shaft and a second hole groove communicated with the first hole groove and extending in the radial direction, lubricating oil is injected into the first hole groove, so that the lubricating oil flows out of the second hole groove, and a lubricating oil film is formed on a matching surface between the pin shaft and the single lug structure.
In this application, first hole groove is two or more to round pin axle axis equipartition.
In this application, the round pin axle with the monaural structure is clearance fit.
The pin shaft connecting structure can solve the abrasion problem of pin shaft connection in the prior art, avoids connection failure caused by abrasion, and saves labor, economy and time cost.
Drawings
In order to more clearly illustrate the technical solutions provided by the present application, the following briefly introduces the accompanying drawings. It is to be expressly understood that the drawings described below are only illustrative of some embodiments of the invention.
Fig. 1 is a schematic view of a pin connection structure according to the present application.
Detailed Description
In order to make the implementation objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application.
In order to solve the wearing and tearing problem between the fitting surface among the prior art's the round pin axle connection structure, this application provides a round pin axle connection structure.
As shown in fig. 1, the pin connection structure provided by the present application includes a first part and a second part for connection, such as a binaural structure 1 and a monaural structure 2 in the embodiment of the present application, and the monaural structure 1 extends into the binaural structure 2. The double-lug structure 1 and the single-lug structure 2 are connected through a pin shaft 4, wherein the pin shaft 4 is provided with a first hole groove 41 extending along the axis of the pin shaft and a second hole groove 42 communicated with the first hole groove 41 and extending in the radial direction, lubricating oil can be extruded or flowed out from the second hole groove 42 by injecting the lubricating oil into the first hole groove 41 at high pressure, and a lubricating oil film is formed on a matching surface 3 between the pin shaft 4 and the single-lug structure 2. The lubricating oil film can convert dry friction between the single lug structure 2 and the pin shaft 4 into elastic flow lubrication, and abrasive particles generated by friction between the single lug structure and the pin shaft can be discharged from the matching surfaces 3 from the left side and the right side through the flowing action of lubricating oil, so that the abrasion problem of pin shaft connection is solved.
In some preferred embodiments of the present application, the number of the first holes 42 may be two or more, and two or more first holes 42 are uniformly distributed along the axis of the pin shaft.
In addition, in the present application, the pin 4 is fitted with the monaural structure 2 with a small clearance, for example, a small clearance of not more than 0.1 mm.
The pin shaft connecting structure can solve the abrasion problem of pin shaft connection in the prior art, avoids connection failure caused by abrasion, and saves labor, economy and time cost.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
