Description
Technical Field
The utility model relates to an exhaust device, in particular to an exhaust device for a gearbox.
Background
When the sealed gearbox is in a working state, along with the operation of various moving parts such as gears and the like in the gearbox body, waste gas can be generated in the gearbox, the generated waste gas is generally directly discharged through an exhaust hole arranged at the top of the gearbox, and after the exhaust hole is arranged, when the gearbox is inclined and inverted, oil in the gearbox can flow out along the exhaust hole, so that the loss of lubricating oil in the gearbox body is caused, and the lubricating effect is influenced; in order to improve the above situation, someone has designed the breather plug for the gearbox ventilates with external, but inside the breather plug still can't effectively prevent external dust particle and steam entering gearbox, lead to gearbox lubricating oil inefficacy, internals corrosion, influence the gearbox function.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to overcome the defects of the technology and provide an exhaust device for a gearbox.
In order to solve the technical problem, the technical scheme provided by the utility model is that the exhaust device for the gearbox comprises: including the gearbox casing, set up in first exhaust hole, the exhaust apparatus on gearbox casing top, exhaust apparatus includes the barrel, sets up in the third exhaust hole of barrel lateral wall, sets up in the top cap of barrel upper end, the barrel lower extreme sets up the diaphragm, and the diaphragm lamellar body is equipped with the second exhaust hole, the diaphragm other end is provided with supporting baseplate, supporting baseplate passes through bracing piece fixed connection with the roof support, be provided with the spring between roof support and the top cap.
As an improvement, the outer wall of the exhaust device is provided with threads, and the exhaust device is in threaded connection with the top end of the gearbox shell.
As a modification, the third exhaust hole is arranged between the top cover and the top supporting plate.
As an improvement, the top cover closes the end of the cylinder body.
As an improvement, the diaphragm, the supporting bottom plate and the supporting top plate are all tightly attached to the inner wall of the cylinder body.
Compared with the prior art, the utility model has the advantages that: the framework is simple, and the assembly is convenient; when the excessive gas is generated in the gear box, the spring is compressed due to the rise of the gas pressure, the gas is exhausted through the exhaust hole in the side wall of the cylinder, and when the gas pressure is not enough to compress the spring, the gear box stops exhausting outwards.
Drawings
FIG. 1 is a schematic illustration of an exhaust for a transmission according to the present invention;
FIG. 2 is a schematic cross-sectional view of an exhaust for a transmission according to the present invention;
fig. 3 is an enlarged view of a portion of an exhaust device for a transmission of the present invention.
As shown in the figure: 1. the gearbox shell 2, the exhaust hole 3, the exhaust device 301, the diaphragm 302, the cylinder 303, the support bottom plate 304, the support rod 305, the support top plate 306, the spring 307, the exhaust hole 308, the top cover 309 and the thread.
Detailed Description
An exhaust device for a transmission according to the present invention will be described in further detail with reference to the accompanying drawings.
With reference to fig. 1 to fig. 3, an exhaust device for a transmission includes a transmission housing 1, a first exhaust hole 2 and an exhaust device 3 disposed at the top end of the transmission housing 1, wherein the exhaust device 3 includes a cylinder 302, a third exhaust hole 307 disposed on the sidewall of the cylinder 302, and a top cover 308 disposed at the upper end of the cylinder, the lower end of the cylinder 302 is provided with a diaphragm 301, a second exhaust hole is disposed on the diaphragm 301, the other end of the diaphragm 301 is provided with a supporting bottom plate 303, the supporting bottom plate 303 and a supporting top plate 305 are fixedly connected by a supporting rod 304, and a spring 306 is disposed between the supporting top plate 305 and the top cover 308.
In a preferred embodiment of the present embodiment, the outer wall of the exhaust device 3 is provided with threads 309, and the exhaust device 3 is screwed with the top end of the transmission housing 1.
As a preferred embodiment of the present embodiment, the third exhaust hole 307 is disposed between the top cover 308 and the top supporting plate 305.
As a preferred embodiment of this embodiment, the cap 308 closes the end of the barrel 302.
In the preferred embodiment of this embodiment, the membrane 301, the bottom support plate 303, and the top support plate 305 are all tightly attached to the inner wall of the cylinder 302.
In the implementation of the utility model, the exhaust device 3 is in threaded connection with the transmission housing 1, when exhaust gas in the transmission is exhausted through the exhaust hole 2 arranged at the top end of the transmission housing 1, the exhaust gas passes through the micro-pores of the diaphragm 301, and then pushes the support bottom plate 304, the support rod 304 and the support top plate 305, thereby causing the compression of the spring 306, when the exhaust gas pressure is large enough, the exhaust gas is exhausted when the spring 306 is pushed to the upper part of the exhaust hole 307, and when the gas pressure is not enough to push the spring 306 to compress, the exhaust gas is stopped.
The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the utility model as defined by the appended claims.
