Abstract
Description
Technical Field
[0001] This utility model relates to a speed reducer exhaust device, belonging to the field of mechanical device technology. Background Technology
[0002] When the speed reducer is running, the internal gears generate heat, which causes the lubricating grease to expand and the internal pressure to increase. The speed reducer vent can release internal pressure and balance the internal and external pressure difference, preventing excessive internal pressure from causing deformation of the seals. Although traditional vents can release grease, they are prone to grease overflow due to structural issues. Therefore, a new type of speed reducer vent is needed to solve the grease overflow problem. Summary of the Invention
[0003] The purpose of this utility model is to provide a speed reducer exhaust device. By using a gooseneck component, it can achieve speed reducer exhaust while preventing speed reducer grease from overflowing. It also has the advantages of simple structure and safety and reliability, and solves the above-mentioned problems existing in the background art.
[0004] The technical solution of this utility model is: a speed reducer exhaust device, comprising a connecting component, a gooseneck component, and an elbow component, wherein the connecting component, the gooseneck component, and the elbow component are connected from bottom to top and are integrally formed, and the connecting component is connected to the inner cavity of the speed reducer; the gooseneck component is a hollow pipe with an internal gooseneck shape, and the inner diameter at both ends of the hollow pipe is larger than the middle inner diameter; the elbow component is a U-shaped bend.
[0005] The connecting component is a threaded sleeve structure, and the connecting component is connected to the upper cover plate of the reducer by threads.
[0006] The beneficial effects of this utility model are: by adopting a gooseneck component, it is possible to exhaust the reducer while preventing the reducer grease from overflowing, and it also has the advantages of simple structure and safety and reliability. Attached Figure Description

[0008] To make the purpose, technical solution, and advantages of this utility model clearer, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described implementation cases are only a small part of this utility model, not all of them. All other implementation cases obtained by those skilled in the art based on the implementation cases of this utility model without creative effort are within the protection scope of this utility model.
[0009] A speed reducer exhaust device includes a connecting component 1, a gooseneck component 2, and an elbow component 3. The connecting component 1, the gooseneck component 2, and the elbow component 3 are connected from bottom to top and are integrally formed. The connecting component 1 is connected to the inner cavity of the speed reducer 4. The gooseneck component 2 is a hollow pipe with an internal gooseneck shape, and the inner diameters at both ends of the hollow pipe are larger than the inner diameter in the middle. The elbow component 3 is a U-shaped bend.
[0010] The connecting component 1 is a threaded sleeve structure, and the connecting component 1 is connected to the upper cover plate of the reducer by threads.
[0011] In practical applications, when the internal temperature of the reducer changes, causing the grease volume to change and thus altering the internal and external pressure difference, the oil-gas mixture rises along the internal channels of this invention under the action of gas pressure. During the ascent, some oil droplets fall due to insufficient speed and their own gravity, while others pass through the gooseneck component. Driven by the rising gas, the airflow velocity increases through the gooseneck component. After exiting the gooseneck component, the gas expands and the velocity decreases, achieving oil-gas separation. The oil and gas fall back, and the gas is discharged. At the same time, external dust cannot enter the reducer due to the obstruction of the elbow component.
[0012] Connected to the reducer via a connecting part, when the internal temperature of the reducer changes, causing a change in the volume of the grease and thus altering the internal and external pressure difference, air flows through the internal hole of this device to connect with the outside. As the air carrying the grease passes through the gooseneck, its volume expands and its velocity decreases, causing the grease to detach from the air and fall back into the reducer. The air is then discharged, balancing the pressure. The elbow outlet faces downwards to prevent external dust from entering the reducer. This device does not have easily worn parts such as sealing rings, and has the advantages of simple structure and long service life. The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
