Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to an aluminum alloy housing for guiding gear lubricant in gearboxes. Background Technology

[0002] As the core component of the power transmission system, the stable lubrication of the gearbox's internal gears directly determines the equipment's service life and transmission efficiency. Especially in commonly used small and medium-sized vehicles such as tricycles and light trucks, the gearbox needs to withstand high-frequency vibration, frequent load fluctuations, and complex outdoor working conditions for a long time, which places higher demands on the precise supply of lubricating fluid.

[0003] Existing gearboxes mostly rely on splash lubrication through gear rotation. On the one hand, they lack a dedicated directional flow guidance structure: after splashing, the lubricant easily flows randomly along the inner wall of the housing, making it difficult to efficiently collect and accurately distribute to each gear meshing area. Some gear sets often experience increased wear due to insufficient lubricant supply, and without a special flow channel design, the lubricant flow rate cannot be controlled. This leads to oil waste at high speeds and lubrication lag at low speeds. On the other hand, they lack an adjustment mechanism adapted to vibration conditions: bumps during vehicle movement can cause the flow guidance structure to shift relative to the gears. Traditional fixed-angle flow guidance components cannot adjust in real time with gear rotation, resulting in not only inaccurate flow guidance but also potential damage to the connection between the flow guidance structure and the housing due to long-term impact caused by the lack of buffering in rigid connections, further affecting lubrication stability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of a dedicated directional flow guidance structure and an inadequate adjustment mechanism for vibration conditions.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an aluminum alloy housing for guiding lubricating fluid in gearbox gears, comprising a lower housing and an upper housing, and further comprising: There are two connecting blocks, which are fixed to the inner wall of the lower housing. A flow guiding assembly, disposed between two connecting blocks, includes a flow guiding plate, wherein a flow storage groove is formed on one side surface of the flow guiding plate; The adjustment component is located on the outer surface of the deflector.

[0006] In a preferred embodiment, the flow guiding component further includes: Multiple diversion holes are provided, which are opened inside the guide plate and connected at one end to the inside of the storage tank. Multiple diversion holes are evenly distributed.

[0007] In a preferred embodiment, the flow guiding component further includes: Multiple guide channels are provided and are located at one end of multiple diversion holes near the storage tank.

[0008] In a preferred embodiment, the plurality of diversion holes are rectangular curved gradient holes.

[0009] In a preferred embodiment, the adjustment component includes: Connecting block two is fixed to one side of the guide plate; There are two connecting blocks, one of which is rotatably connected to one side surface of connecting block two via a rotating shaft; Connecting block four is fixed to the upper surface of the lower housing; The damper is fixed between the two connecting blocks three; A spring is positioned between the two connecting blocks. One side surface of another connecting block three is rotatably connected to one side of connecting block four via a rotating shaft.

[0010] In a preferred embodiment, the inner wall surface of the spring is fitted onto the outer surface of the damper.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the centrifugal force generated by the rotation of the gears splashes lubricant onto the arc-shaped surface of the guide plate. The arc-shaped structure guides the lubricant into the reservoir. Under inertia, the lubricant in the reservoir is guided through a funnel-shaped guide channel into the distribution holes. Multiple equidistant distribution holes correspond to different gear sets. The distribution holes are rectangular, curved, gradually tapering holes with a cross-section that gradually decreases from the reservoir end to the outlet end. This accelerates the lubricant flow rate and precisely guides it to the corresponding gear meshing area, achieving a stable and precise supply of gear lubricant.

[0012] In this invention, when the gear rotates at high speeds, its inertia is large, resulting in a strong impact and thrust on the guide plate, which pushes the guide plate to deflect around connecting block one. When the gear rotates at low speeds, its inertia is small, its thrust is weak, and the guide plate is less impacted. The deflection of the guide plate drives the movement of connecting block two, causing the connected connecting block three to swing around the axis, which in turn drives another connecting block three to move in tandem. The spring sleeved outside the damper deforms with the swing, and the damper dissipates the vibration energy, supporting the guide plate, buffering the impact, and adjusting its angle in real time to ensure that the flow storage tank, the flow diversion hole and the gear meshing area are matched, thus achieving precise flow guidance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0016] Please see Figures 1-6 This embodiment provides an aluminum alloy housing for guiding lubricating fluid to gearbox gears, and its specific concept is as follows: In one specific implementation, it includes a lower housing 1 and an upper housing 2, and further includes: There are two connecting blocks 6, which are fixed to the inner wall of the lower housing 1; A flow guiding component is disposed between two connecting blocks 6, including a flow guiding plate 3, and a flow storage groove 4 is provided on one side surface of the flow guiding plate 3; The adjustment component is located on the outer surface of the guide plate 3.

[0017] As one specific implementation method, the flow guiding component also includes: Multiple diversion holes 5 are provided, which are opened inside the guide plate 3 and one end is connected to the inside of the storage tank 4. Among them, multiple diversion holes are equidistantly distributed.

[0018] As one specific implementation method, the flow guiding component also includes: Multiple guide channels 12 are provided and are opened at one end of multiple diversion holes 5 near the storage tank 4.

[0019] As one specific implementation method, the multiple diversion holes 5 are rectangular curved gradient holes.

[0020] In this embodiment, the specific type of the flow guiding component can be various, and this application does not limit it. In an optional embodiment, as an example of a flow guiding component, the flow guiding component includes: a flow guide plate 3, a flow storage tank 4, a flow diversion hole 5, and a guide groove 12, the specific quantity of each component as follows: Figures 2-5 As shown, the settings are as follows: In this embodiment, a guide plate 3 is provided, which is connected to the inner wall surface of the lower housing 1 by two connecting blocks 6. The guide plate 3 is arc-shaped, and the flow direction of the lubricant is changed by the angle between the guide plate 3 and the lower housing 1.

[0021] The reservoir 4 for accumulating lubricating fluid is cut on the outer surface of the guide plate 3 by lathe cutting. The diversion hole 5, used to divert the lubricating fluid, passes along the length of the guide plate 3; The guide groove 12, which is used to guide the lubricant into the distribution hole 5, is machined on one end of the distribution hole 5 by a lathe, and the guide groove 12 is trumpet-shaped.

[0022] In this embodiment, during use, the centrifugal force generated by the rotation of the gears splashes the lubricant onto the arc-shaped surface of the guide plate 3. The arc-shaped structure guides the lubricant to converge into the reservoir 4. Under the action of inertia, the lubricant in the reservoir 4 is efficiently introduced into the diversion hole 5 through the funnel-shaped guide groove 12. Multiple equally spaced diversion holes 5 correspond to different gear sets, ensuring that each meshing area can obtain directional lubrication. Since the diversion hole 5 is a rectangular curved gradient hole, its cross-section gradually decreases from the end of the reservoir 4 to the outlet end, which can accelerate the flow rate of the lubricant and accurately guide it to the corresponding gear meshing area, thereby achieving a stable and accurate supply of gear lubricant. Example 2

[0023] like Figures 1-6 As shown, based on Embodiment 1, this embodiment also provides an adjustment component, disposed on the outer surface of the guide plate 3, including: Connecting block 2 7 is fixed to one side of the guide plate 3; There are two connecting blocks 3 8, one of which is rotatably connected to one side surface of connecting block 2 7 via a rotating shaft; Connecting block 411 is fixed to the upper surface of the lower housing 1; Damper 9 is fixed between the two connecting blocks 3 and 8; Spring 10 is positioned between the two connecting blocks 3 and 8; One side surface of another connecting block 3 8 is rotatably connected to one side of connecting block 4 11 via a rotating shaft.

[0024] In one specific implementation, the inner wall surface of the spring 10 is fitted onto the outer surface of the damper 9.

[0025] In this embodiment, during use, different gear rotation speeds will cause differences in the inertia generated by the splashing of lubricating fluid. Under high rotation speed conditions, the lubricating fluid has greater inertia, resulting in a stronger impact thrust on the guide plate 3, which pushes the guide plate 3 to deflect around the connecting block 6 at a certain angle. Under low rotation speed conditions, the lubricating fluid has less inertia, the thrust is weakened, and the impact on the guide plate 3 is reduced. During this process, the deflection of the guide plate 3 causes the connecting block 7 fixed on it to move synchronously, causing the connecting block 8 rotatably connected to it to swing around the axis, thereby driving the other connecting block 8 to move in tandem. The spring 10, which is sleeved outside the damper 9, undergoes an appropriate elastic deformation as the connecting block 3 8 swings. At the same time, the damper 9 dissipates the vibration energy generated by the inertial impact through its own damping effect. This provides flexible support for the guide plate 3, buffers the impact of the lubricating fluid inertia on the guide plate 3 at different speeds, and can also adjust the angle of the guide plate 3 in real time according to the magnitude of inertia. This ensures that the reservoir 4 and the diversion hole 5 always maintain a suitable position with the gear meshing area, achieving accurate guidance of the lubricating fluid under different working conditions and avoiding the problem of inaccurate guidance caused by speed fluctuations.

[0026] Working principle: The lower housing 1 and the upper housing 2 enclose a chamber for accommodating the gear. Two connecting blocks 6 are fixed to the inner wall of the lower housing 1. The guide plate 3 is installed on the inner side of the lower housing 1 through the connecting blocks 6 and is arc-shaped. When the gear rotates, the centrifugal force it generates splashes the lubricant onto the arc-shaped surface of the guide plate 3. The arc-shaped guide plate 3 guides the lubricant, causing it to collect in the reservoir 4 opened on its outer surface. Under the action of inertia, the lubricant in the reservoir 4 enters the diversion holes 5, which are distributed and equidistantly arranged along the length of the guide plate 3, through the trumpet-shaped guide groove 12 opened at one end of the diversion hole 5 near the reservoir 4. The diversion hole 5 is a rectangular curved gradient hole. After the lubricant flows through the internal channel of the diversion hole 5, it is finally discharged from the outlet of the diversion hole 5 to the corresponding gear meshing area.

[0027] In the adjustment assembly, connecting block 2 7 is fixed to one side of the outer surface of the guide plate 3, and connecting block 4 11 is fixed to the upper surface of the lower housing 1; of the two connecting blocks 3 8, one is rotatably connected to connecting block 2 7 via a rotating shaft, and the other is rotatably connected to connecting block 4 11 via a rotating shaft. The two ends of the damper 9 are respectively fixed between the two connecting blocks 3 8. The inner wall of the spring 10 is sleeved on the outer surface of the damper 9 and its two ends are also connected to the two connecting blocks 3 8. When the gear rotation changes, the inertia generated by the splashing of lubricating fluid changes accordingly. The inertial force pushes the guide plate 3 to deflect around connecting block 1 6. The deflection of the guide plate 3 drives the connecting block 2 7 to move synchronously. The connecting block 2 7 pushes the connecting block 3 8 connected to it to rotate around the rotating shaft. The connecting block 3 8 further drives the damper 9 and the spring 10 to extend and retract, thereby pushing the other connecting block 3 8 to rotate around the rotating shaft connected to the connecting block 4 11. During this process, the spring 10 generates elastic deformation, and the damper 9 generates damping motion inside to balance the force.
