Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a reverse speed reducer housing with built-in conformal chill. Background Technology

[0002] Reverse gearbox housings with built-in conformal chills are mainly used in mechanical systems that require efficient transmission and heat dissipation. Traditional gearboxes often suffer from reduced efficiency and lifespan due to increased operating temperature. However, by embedding conformal chills inside the housing, heat dissipation performance can be effectively improved, heat accumulation can be reduced, stable operation of the gearbox can be ensured, and service life can be extended. This makes them particularly suitable for industrial applications in high-load and high-temperature environments.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing reverse gearbox housing cannot achieve efficient heat dissipation, sealing, and shock absorption to ensure stable operation and lifespan. High temperature accelerates the oxidation and decomposition of grease, reducing viscosity and lubrication performance, and aggravating wear of gears or bearings. Metal parts undergo microscopic distortion due to temperature differences, which destroys the original precise meshing clearance, causing transmission error accumulation or even jamming. Excess heat is converted into energy loss, making the actual output power lower than the nominal value, especially under frequent start-stop conditions. Local hot spots may trigger the aging and cracking of the sealing ring, allowing impurities to seep in and contaminate internal components, forming a vicious cycle. At the same time, high temperature accelerates the deterioration of the insulation layer of electrical components, creating a potential short circuit hazard.

[0004] Therefore, this utility model proposes a reverse gearbox housing with built-in conformal chills to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reverse gearbox housing with a built-in conformal chill.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a reverse gear reducer housing with built-in conformal chills, comprising a lower housing and an upper housing disposed on the lower housing, and further comprising: A heat dissipation assembly includes chills installed in both the lower and upper housings, connection ports on both the lower and upper housings, guide pipes installed in both the lower and upper housings, the guide pipes being connected to the connection ports, a rubber ring on the lower housing, and heat dissipation fins on both the lower and upper housings. The buffer assembly includes a steel mesh reinforced composite layer on both the lower and upper housings, a polyurethane damping adhesive on the steel mesh reinforced composite layer, and an aluminum alloy shell on the polyurethane damping adhesive.

[0007] Furthermore, a limiting groove is provided on the lower housing, and the rubber ring is disposed in the limiting groove.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the limiting groove of the lower housing is used to place the rubber ring, and the contour of the limiting groove is precisely matched with the rubber ring, which can limit the displacement of the rubber ring during assembly and operation, prevent it from deviating from the sealing position due to vibration, and ensure reliable sealing at the joint of the upper and lower housings.

[0009] Furthermore, magnetic blocks are provided on both the lower and upper housings.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the magnetic blocks on the lower and upper boxes attract each other when the boxes are closed, generating a pre-tightening force to assist in positioning, and the upper and lower boxes are quickly aligned by magnetic force during assembly, reducing assembly deviation.

[0011] Furthermore, both the lower and upper housings are connected to honeycomb-shaped reinforcing plates.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the honeycomb reinforcing plate connecting the lower and upper boxes uses the honeycomb structure to disperse stress, its internal holes reduce weight, and at the same time the honeycomb wall transmits external forces to all sides, improving the overall rigidity of the box, reducing deformation during operation, and enhancing impact resistance.

[0013] Furthermore, a first fixing block is connected to the upper housing, and a second fixing block is connected to the lower housing on the side near the first fixing block.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the first fixing block of the upper box and the second fixing block of the lower box are set in a corresponding manner to provide a force carrier for the bolt connection. The two are precisely aligned so that the preload of the bolts is evenly applied to the box joint surface, ensuring a firm connection.

[0015] Furthermore, the first fixing block is threaded with a bolt, which is threaded into the second fixing block.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the bolts on the first fixing block are screwed into the second fixing block to tightly connect the upper and lower housings. The threaded connection can adjust the preload and is easy to disassemble and assemble, ensuring that the housing will not loosen during operation.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, regarding heat dissipation of the reverse gearbox housing, the chills built into the lower and upper housings utilize high thermal conductivity to quickly absorb heat generated during operation. The heat is then transferred through the housing to the surface heat dissipation fins for dissipation. Simultaneously, the guide pipe connected to the connection port allows coolant to flow in, circulating through the pipeline to remove the heat accumulated on the chills. Rubber rings ensure a seal at the joint between the upper and lower housings. For cushioning, the steel mesh reinforced composite layer serves as the basic framework to enhance the housing's resistance to deformation. The polyurethane damping adhesive on its surface absorbs vibration energy, and the outer aluminum alloy shell further disperses the impact force, achieving efficient heat dissipation, sealing, and cushioning vibration reduction, ensuring stable operation and long service life.

[0020] 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.

[0021] like Figure 1 - Figure 5As shown, this embodiment provides a technical solution: a reverse gear reducer housing with built-in conformal chills, including a lower housing 1 and an upper housing 2 disposed on the lower housing 1, and further including: The heat dissipation component 3 includes a chill 31 installed in both the lower housing 1 and the upper housing 2. Both the lower housing 1 and the upper housing 2 are provided with a connection port 32. Both the lower housing 1 and the upper housing 2 are provided with a guide pipe 33 connected to the connection port 32. The lower housing 1 is provided with a rubber ring 35. Both the lower housing 1 and the upper housing 2 are provided with heat dissipation fins 36. The buffer assembly 4 includes a steel mesh reinforced composite layer 43 on both the lower housing 1 and the upper housing 2. A polyurethane damping adhesive 42 is applied to the steel mesh reinforced composite layer 43, and an aluminum alloy shell 41 is mounted on the polyurethane damping adhesive 42. For heat dissipation in this reverse gearbox housing, the chills 31 built into the lower housing 1 and upper housing 2 utilize high thermal conductivity to quickly absorb heat during operation. The heat is transferred through the housing to the surface heat dissipation fins 36 for dissipation. Simultaneously, the guide pipe 33 connected to the connection port 32 allows coolant to circulate and remove the heat accumulated in the chills 31. A rubber ring 35 ensures a seal at the joint between the upper housing 2 and the lower housing 1. For buffering, the steel mesh reinforced composite layer 43 serves as the basic framework to enhance the housing's resistance to deformation. The polyurethane damping adhesive 42 on its surface absorbs vibration energy, and the outer aluminum alloy shell 41 further disperses the impact force, achieving efficient heat dissipation, sealing, and buffering vibration reduction, ensuring stable operation and long service life.

[0022] like Figure 1 - Figure 4 As shown: A limiting groove 34 is provided on the lower housing 1, and a rubber ring 35 is placed in the limiting groove 34. The limiting groove 34 of the lower housing 1 is used to place the rubber ring 35. The contour of the limiting groove 34 is precisely matched with the rubber ring 35, which can limit the displacement of the rubber ring 35 during assembly and operation, prevent it from deviating from the sealing position due to vibration, and ensure reliable sealing at the joint of the upper and lower housings 1. Both the lower housing 1 and the upper housing 2 are provided with magnetic blocks 37. The magnetic blocks 37 on the lower housing 1 and the upper housing 2 attract each other when the housing is closed, generating a pre-tightening force to assist in positioning. During assembly, the upper and lower housings 1 are quickly aligned by magnetic force to reduce assembly deviation. Both the lower housing 1 and the upper housing 2 are connected with honeycomb reinforcing plates 38. The honeycomb reinforcing plates 38 connected to the lower housing 1 and the upper housing 2 use the honeycomb structure to disperse stress. Its internal holes reduce weight, and at the same time, the honeycomb wall transmits external force to the surroundings, improving the overall rigidity of the housing, reducing deformation during operation, and enhancing impact resistance. like Figure 1 - Figure 4As shown, a first fixing block 44 is connected to the upper housing 2, and a second fixing block 45 is connected to the lower housing 1 on the side near the first fixing block 44. The first fixing block 44 of the upper housing 2 and the second fixing block 45 of the lower housing 1 are set correspondingly to provide a force carrier for the bolt 46 connection. The two are precisely aligned so that the preload of the bolt 46 is evenly applied to the housing mating surface, ensuring a firm connection. The bolt 46 is threadedly connected to the first fixing block 44, and the bolt 46 is threadedly connected to the second fixing block 45. The bolt 46 on the first fixing block 44 is screwed into the second fixing block 45, tightly connecting the upper housing 2 and the lower housing 1. The threaded connection can adjust the preload and is easy to disassemble and assemble, ensuring that the housing will not loosen during operation.

[0023] Working principle: like Figure 1 - Figure 5 As shown, in terms of heat dissipation, the chills 31 built into the lower housing 1 and upper housing 2, with their high thermal conductivity, quickly absorb the heat generated during operation. Part of the heat is transferred through the housing to the heat dissipation fins 36 on the surface and dissipated to the outside through air convection. The other part is channeled into the coolant through the guide pipe 33 connected to the connection port 32, and the heat accumulated in the chills 31 is carried away through the pipeline circulation. The contour of the limiting groove 34 of the lower housing 1 matches the rubber ring 35, which can limit its displacement during assembly and operation, preventing it from deviating from the sealing position due to vibration, and ensuring a reliable seal at the joint of the upper and lower housings 1. Simultaneously, the magnetic blocks 37 on the lower housing 1 and upper housing 2 attract each other when closed, generating a pre-... Tightening assists positioning and reduces assembly deviation. In terms of buffering and vibration reduction, the steel mesh reinforced composite layer 43 serves as the basic skeleton to enhance the deformation resistance. The polyurethane damping adhesive 42 on the surface absorbs vibration energy, and the outer aluminum alloy shell 41 further disperses the impact force. The honeycomb reinforcing plate 38 connecting the lower box 1 and the upper box 2 utilizes the honeycomb structure to disperse stress and improve overall rigidity. During assembly, the first fixing block 44 of the upper box 2 and the second fixing block 45 of the lower box 1 are precisely aligned, and the bolts 46 pass through the two to achieve a tight connection. The pre-tightening force is evenly applied to the joint surface to ensure that it does not loosen during operation. Through the above structural cooperation, the box achieves efficient heat dissipation, reliable sealing and buffering, ensuring stable operation and service life.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
