Embodiment 1

[0047] See Figure 1 to Figure 7 , A gearbox oil level observation device, comprising an inner plug 2, an outer plug 3 and a star metal bracket 4, the star metal bracket 4 includes a plurality of interconnected sub-frames 41, the bottom of the plurality of sub-frames 41 Are connected to each other to enclose a central hole 42, the tops of the multiple sub-frames 41 are evenly distributed along the same circle, and the circle where the tops of the multiple sub-frames 41 are located is concentrically arranged with the central hole 42;

[0048] The inner plug 2 is provided with an inner front cavity 21 and an inner rear cavity 22 coaxial with the inner plug 2 and an outer front cavity 31 and an outer front cavity 31 coaxial with the outer plug 3 are opened inside the outer plug 3 The posterior cavity 32, the inner anterior cavity 21 communicate with the outer posterior cavity 32 through the inner posterior cavity 22 and the outer anterior cavity 31 in turn. The junction of the outer...

Embodiment 2

[0050] The basic content is the same as Example 1, the difference is:

[0051] The outer plug 3 is provided with a No. 1 extension end 33 and a No. 2 extension end 34 inside, the top of the No. 1 extension end 33 is connected to the bottom wall of the inner plug 2, and the side of the No. 1 extension end 33 is provided There is an outer ring groove 51 to install the outer O-ring 5, the top of the outer O-ring 5 is in contact with the top wall of the outer ring groove 51, and the bottom of the outer O-ring 5 is connected to the transparent sheet 1 (can be a transparent tempered glass plate) The transparent sheet 1 is located in the sheet cavity 11 formed by the first extension end 33, the side wall of the outer plug 3, and the second extension end 34. The bottom of the transparent sheet 1 is in contact with the top of the inner end of the inner leg 35. The outer end of the leg 35 is connected with the bottom of the No. 2 extension end 34, and the top of the No. 2 extension end 34 ...

Embodiment 3

[0053] The basic content is the same as Example 1, the difference is:

[0054] In an assembling method of the aforementioned gearbox oil level observation device, the star-shaped metal bracket 4 is installed according to the following steps:

[0055] First take a star-shaped metal bracket 4 to be installed. When assembling, first install the lower end surface of the star-shaped metal bracket 4 on the positioning step of the star-shaped metal bracket 4 between the inner rear cavity 22 and the outer front cavity 31, that is, the outer step 24 Then use a press tool to press the inner step 23 between the inner front cavity 21 and the inner rear cavity 22. Under the action of the pressure, the body material at the inner step 23 is subjected to squeezing force, and the body material is destroyed, deformed, Stacked on the star-shaped metal bracket 4, thereby fixing the star-shaped metal bracket 4 on the outer step 24, and the assembly can be completed at this time.

Abstract

A speed change box oil level observation device comprises an inner end cap, an outer end cap, a star-shaped metal support and a transparent piece; the inner end cap is internally provided with an inner front cavity and an inner rear cavity; the outer end cap is internally provided with an outer front cavity and an outer rear cavity; the inner front cavity communicates with the outer rear cavity sequentially through the inner rear cavity and the outer front cavity; an inner step is arranged at the position of the joint of the inner front cavity and the inner rear cavity; an outer step is arranged at the position of the joint of the inner rear cavity and the outer front cavity; the star-shaped metal support is embedded in a support groove formed between the inner step and the outer step; the transparent piece is embedded in the position of the joint of the outer front cavity and the outer rear cavity; when the star-shaped metal support is assembled, the inner step needs to be downwards pressed and deformed so that the star-shaped metal support can be pressed; and when the transparent piece is assembled, an inner elbow feet need to be rotated and extruded in the direction of the outer front cavity so that the transparent piece and an outer O-shaped ring can be pressed. By means of the speed change box oil level observation device, the oil level height of a speed change box can be judged, the accuracy degree is high, observation is convenient, the assembly efficiency is high, the sealing performance is high, and it can be avoided that lubricating oil leaks from the interior and the exterior of the observation device.

Description

Technical field [0001] The invention relates to a gearbox oil level observation device and an assembly method thereof, and is particularly suitable for improving the convenience and accuracy of oil level observation. Background technique [0002] At present, the inspection and addition of gearbox lubricating oil are generally carried out at the gearbox oil filling hole, and the oil filling hole is equipped with a filling plug. The refueling plug is a solid structure, and the oil level in the gearbox cannot be directly observed through the refueling plug. When you need to check the height of the oil level, you must first remove the filler plug on the filler hole before the inspection can be performed. After checking the height of the oil level, install the filler plug back. The refueling plug is screwed on the shell through a thread, and the end face is sealed with a gasket. When disassembling the refueling plug to check the oil level, whether it is necessary to refuel or not, i...
