Description

Technical Field

[0001] This utility model relates to the field of gearbox oil spill prevention technology, specifically a gearbox with an oil spill prevention and ventilation structure. Background Technology

[0002] The gearbox is a power transmission device. When the gears inside rotate at high speed, the temperature of the gearbox and its internal oil will rise. The internal lubricating oil will also be atomized by the rotating gears, causing the temperature of the air inside the gearbox to rise and its volume to expand. The atomized oil vapor is quickly discharged from the vent plug. As the oil vapor is discharged, it gradually cools down and re-condenses into small oil droplets that adhere to the vent plug wall and outlet. A large number of small oil droplets gather and form oil droplets that slide off, causing the gearbox oil to leak.

[0003] Existing gearboxes with oil spill prevention ventilation structures, such as the gearbox oil spill prevention ventilation device and gearbox disclosed in publication number CN223152719U, have an oil mist-carrying airflow in the gearbox that passes through a ventilation channel and a damping adsorption component in sequence. When passing through the ventilation channel, the flow velocity is reduced and the condensation and reflux effect is improved. However, the deceleration structure and the adsorption structure of this oil spill prevention ventilation structure are set separately, which makes its condensation effect poor. Therefore, we propose a gearbox with an oil spill prevention ventilation structure. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: A gearbox with an oil spill prevention and venting structure includes: a gearbox body and a venting assembly; the venting assembly includes a lower vent pipe fixedly connected to the upper end of the gearbox body, a heat sink fixedly connected to the upper end of the lower vent pipe, an upper vent pipe fixedly connected to one side of the upper part of the heat sink, a heat conduction frame movably installed inside the heat sink, multiple sets of gathering plates fixedly installed in a staggered arrangement on both sides inside the heat conduction frame, a support plate fixedly installed at the upper end of each gathering plate, and damping adsorption components movably placed on each support plate.

[0006] Preferably, multiple sets of heat sinks are also fixedly installed on both sides of the outer end of the heat sink.

[0007] Preferably, the upper end of the support plate is also provided with oil drain holes.

[0008] Preferably, each of the agglomeration plates is also provided with an oil drain port at its lower part.

[0009] Preferably, an exhaust port is also provided on one side of the heat-conducting frame.

[0010] Preferably, the top of the heat-conducting frame is also provided with a lifting opening.

[0011] Preferably, the top of the heat sink is also provided with a threaded opening, and a threaded plug is threadedly connected inside the threaded opening.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, after the oil and gas in the gearbox body are transported to the heat dissipation box through the lower vent pipe, they will be gathered by multiple gathering plates and adsorbed by the gathered structure in the heat dissipation box. This will improve the uniformity of oil adsorption in the oil and gas and reduce oil spillage by gathering and adsorbing the oil and gas in a timely manner. At the same time, the heat conduction frame at the outer end of the gathering plate and the damping adsorption component, as well as the heat dissipation fins at the outer end of the heat dissipation box, can also quickly dissipate heat from the inner end of the heat dissipation box during use, thereby reducing the temperature of the internal oil and gas and accelerating the condensation of the oil.

[0013] 2. In this utility model, the agglomerating plate and damping adsorption component inside the heat dissipation box can also be easily disassembled from inside the heat dissipation box, thereby facilitating the maintenance of the agglomerating plate and damping adsorption component.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a gearbox with an oil spill prevention and venting structure.

[0018] Example 1: Combination Figure 1-5 As shown, the present invention provides a gearbox with an oil spill prevention and venting structure, comprising: a gearbox body 100 and a venting assembly 200; the venting assembly 200 includes a lower vent pipe 201 fixedly connected to the upper end of the gearbox body 100, a heat sink 202 fixedly connected to the upper end of the lower vent pipe 201, an upper vent pipe 203 fixedly connected to one side of the upper part of the heat sink 202, a heat conduction frame 204 movably installed inside the heat sink 202, and multiple sets of gathering plates 205 staggered and fixedly installed on both sides inside the heat conduction frame 204, with the upper ends of the gathering plates 205 all fixedly... The support plate 206 is fixedly installed, and the damping adsorption component 207 is movably placed on the support plate 206. Multiple sets of heat sinks 208 are also fixedly installed on both sides of the outer end of the heat sink 202. Oil drain holes 209 are also arranged on the upper end of the support plate 206. Oil drain ports 210 are also opened on the lower part of the gathering plate 205. An exhaust port 211 is also opened on one side of the heat conduction frame 204. A lifting port 212 is also opened on the top of the heat conduction frame 204. A threaded port 213 is also provided on the top of the heat sink 202. A threaded plug 214 is also threadedly connected inside the threaded port 213.

[0019] Specifically, the gearbox is a power transmission device. The high-speed operation of the gears inside causes the gearbox and its internal oil temperature to rise, and the internal lubricating oil is atomized by the rotating gears, leading to oil spillage. The oil vapor inside the gearbox body 100 is transported to the heat sink 202 via the lower vent pipe 201. Inside the heat sink 202, it is collected by multiple gathering plates 205 and then by the damping adsorption structure 207. This collection and timely adsorption improves the uniformity of oil adsorption in the oil vapor, reducing oil spillage. Simultaneously, the heat conduction frame 204 at the outer end of the gathering plates 205 and the damping adsorption structure 207, as well as the heat sink 208 at the outer end of the heat sink 202, also provide rapid heat dissipation during use, thereby reducing the temperature of the internal oil vapor and accelerating oil condensation. The gathering plates 205 and 207 within the heat sink 202... The damping adsorption component 207 and the heat sink 202 can be easily disassembled to facilitate the maintenance of the gathering plate 205 and the damping adsorption component 207. The oil drain hole 209 at the upper end of the support plate 206 and the oil drain port 210 at the lower part of the gathering plate 205 are mainly used for the downward flow of oil after adsorption in the damping adsorption component 207. The support plate 206 at the upper end of the gathering plate 205 is mainly used for the installation of the damping adsorption component 207. The lifting port 212 opened at the top of the heat conduction frame 204 is mainly used to facilitate the lifting during the disassembly of the heat conduction frame 204. The threaded plug 214 installed in the threaded port 213 is mainly used for the fixation and sealing of the top of the heat sink 202. The threaded port 213 and the threaded plug 214 are precision thread structures. The heat conduction frame 204 installed in the heat sink 202 is mainly used to facilitate the unified disassembly and assembly of the heat conduction frame 204 and its inner end gathering plate 205 and damping adsorption component 207.

[0020] Working principle and usage process of this utility model: During operation of the gearbox body 100, the increased internal temperature causes the lubricating oil to atomize and form oil vapor, which enters the heat sink 202 through the lower vent pipe 201. After entering the heat sink 202, the oil vapor is collected by the gathering plates 205 between the heat conduction frames 204, and then uniformly transported to the upper damping adsorption components 207 for adsorption of the oil in the oil vapor, allowing the oil to flow back into the gearbox body 100. The multiple sets of gathering plates 205 between the heat conduction frames 204 and the damping adsorption components 207... Appendix 207 can perform multiple rounds of aggregation and adsorption of oil and gas to ensure the uniformity of oil adsorption in the oil and gas. At the same time, the heat conduction frame 204 can also transfer the heat from the inner end to the heat sink 208 at the outer end of the heat sink 202 for external heat dissipation, thereby reducing the internal temperature of the heat sink 202 and thus reducing the temperature of the internal oil and gas, accelerating the condensation of the oil. In addition, the entire heat conduction frame 204 can be easily disassembled from the top of the heat sink 202 for convenient maintenance of the inner end aggregation plate 205 and the damping adsorption component 207 of the heat conduction frame 204.
