Abstract
The utility model relates to an engine, in particular to an engine rocker arm mounting structure which comprises a mounting seat, a mounting shaft and a rocker arm, wherein the mounting seat is provided with a mounting hole matched with the mounting shaft, the mounting shaft is radially provided with a threaded hole, and the mounting seat is detachably connected with a fixing bolt in threaded fit with the threaded hole. The problem that the rocker arm mounting structure of the engine in the prior art is easy to wear abnormally and cannot reach the design service life is solved.
Description
Technical Field
The utility model relates to an engine, in particular to an engine rocker arm mounting structure.
Background
A rocker arm for driving an intake valve and an exhaust valve to open and close in an engine is hinged to a mounting seat through a mounting shaft, and the mounting seat is provided with a mounting hole matched with a shaft hole of the mounting shaft. During the operation of the engine, the rocker arm can swing around the mounting shaft, so that the normal operation of the engine is ensured. Along with the use of the engine, abnormal wear always occurs among the rocker arm, the mounting shaft and the mounting seat, so that the wear speed is high, the designed service life time cannot be reached, and the engine is easily damaged due to early failure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an engine rocker arm mounting structure, which aims to solve the problem that the rocker arm mounting structure of an engine in the prior art is easy to generate abnormal wear and cannot reach the designed service life.
In order to achieve the purpose, the basic scheme of the utility model provides an engine rocker arm mounting structure which comprises a mounting seat, a mounting shaft and a rocker arm, wherein the mounting seat is provided with a mounting hole matched with the mounting shaft, the mounting shaft is radially provided with a threaded hole, and the mounting seat is detachably connected with a fixing bolt in threaded fit with the threaded hole.
The beneficial effect of this basic scheme lies in: by adopting the arrangement, the installation shaft is in threaded connection with the fixing bolt through the threaded hole, so that the installation shaft cannot move by utilizing the fit clearance between the installation shaft and the installation hole, the installation shaft is axially and radially fixed relative to the installation seat, abnormal abrasion among the installation seat, the rocker arm and the installation shaft is reduced, and the service life of the rocker arm installation structure is ensured.
In order to fix the mounting shaft conveniently, a through hole matched with the fixing bolt is formed in the mounting seat.
In order to facilitate the assembly of the fixing bolt, an opening opposite to the through hole is formed in the rocker arm. With this arrangement, the weight of the rocker arm can be reduced.
For ease of assembly, the opening is located at the top of the rocker arm.
Drawings
FIG. 1 is a schematic diagram of an embodiment of an engine rocker arm mounting structure of the present invention;
FIG. 2 is a cross-sectional view A-A of FIG. 1;
fig. 3 is a sectional view taken along line B-B in fig. 1.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: cylinder head C, rocking arm 1, fixing bolt 2, installation axle 3, mount pad 4, opening 11.
The embodiment is substantially as shown in figures 1, 2 and 3 of the accompanying drawings: the utility model provides an engine rocker arm mounting structure, includes mount pad 4, installation axle 3 and rocking arm 1, mount pad 4 and the cylinder head C integrated into one piece of engine, be provided with on mount pad 4 with install 3 clearance fit's of axle mounting hole, be provided with respectively on the rocking arm 1 with the connecting hole that the both ends of mounting hole are relative, installation axle 3 passes mounting hole and connecting hole simultaneously to make rocking arm 1 realize articulating with mount pad 4 through installation axle 3. The middle part of installation axle 3 is along radially being provided with the screw hole, is provided with the via hole relative with the screw hole on mount pad 4, and the via hole department of mount pad 4 wears to be equipped with screw hole screw-thread fit's fixing bolt 2 to make installation axle 3 pass through fixing bolt 2 and realize and the relative fixation between mount pad 4. An opening 11 through which the fixing bolt 2 passes and opposite to the through hole is provided on the rocker arm 1, so that the fixing bolt 2 facilitates the assembling operation through the opening 11.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
