Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a motor heat dissipation connection structure. Background Technology

[0002] As core components of power transmission, motors and speed reducers are widely used in industrial automation, mechanical equipment, transportation equipment and other fields. In traditional designs, the output end of the motor is rigidly connected to the speed reducer through a flange or adapter assembly to achieve torque transmission and speed regulation.

[0003] However, this installation method has significant drawbacks in long-term operation, particularly in terms of sealing failure and grease leakage risks caused by heat conduction. Specifically, during continuous operation, the motor's internal windings, stator, and other components generate a large amount of heat due to the current. Because the motor and reducer are directly connected without effective heat insulation, the heat generated by the motor is directly transferred to the reducer housing, causing a significant increase in the internal temperature of the reducer. Furthermore, critical sealing positions such as the reducer end cover and input shaft often use rubber or polymer seals such as O-rings and lip seals. Under long-term high-temperature conditions, these seals are prone to thermal expansion, hardening, or aging and cracking, leading to increased deformation and gaps at the sealing interface and a severe decrease in dynamic sealing performance. Lubricating grease inside the reducer can seep out along the gap between the input shaft and the end cover, and some grease may even seep into the motor through the motor output end, causing short circuit damage.

[0004] Therefore, providing a motor connection structure with good heat dissipation performance is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model discloses a motor heat dissipation connection structure to solve the above-mentioned technical problems existing in related technologies.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] This application provides a motor heat dissipation connection structure, which includes a motor, a speed reducer, and an adapter assembly; wherein:

[0008] The adapter assembly includes a first adapter, a second adapter, and a heat insulation component. One of the first adapter and the second adapter has a insertion recess, and the other has an insertion protrusion. The insertion recess has a first sidewall and a second sidewall distributed in the circumferential direction. When the insertion recess and the insertion protrusion are engaged, there is an assembly gap between the first sidewall and the second sidewall and the insertion protrusion. A portion of the heat insulation component is located within the assembly gap to transmit torque. The output end of the motor is connected to the first adapter, and the input end of the reducer is connected to the second adapter.

[0009] Furthermore, the heat insulation component includes an annular base and a plurality of insulating portions connecting the annular base, the plurality of insulating portions being distributed circumferentially along the annular base, and the insulating portions being used for assembly within the assembly gap.

[0010] Furthermore, the insulating part is a columnar structure connected to the outer periphery of the annular substrate, and the cross section of the insulating part perpendicular to the axial direction of the heat insulation member is circular or spindle-shaped.

[0011] Furthermore, the motor heat dissipation connection structure also includes a mounting base, which is located between the motor and the reducer, and both the motor and the reducer are connected and fixed to the mounting base. The adapter component is located inside the mounting base, and the output end of the motor and the input end of the reducer both extend into the mounting base.

[0012] Furthermore, the mounting base includes a cylindrical base, a first mating plate, and a second mating plate. The first mating plate and the second mating plate are respectively disposed at both ends of the cylindrical base in its axial direction. The motor is connected to the first mating plate through a threaded connector, and the reducer is connected to the second mating plate through a threaded connector.

[0013] Furthermore, an opening penetrating the cylindrical substrate is provided on the side wall of the cylindrical substrate.

[0014] Furthermore, the length of the opening in the axial direction of the cylindrical base is greater than the length of the adapter assembly, and the width of the opening in the circumferential direction of the cylindrical base is greater than the diameter of the adapter assembly.

[0015] Furthermore, the mounting base also includes a plurality of heat sinks connected to the cylindrical base, the plurality of heat sinks being distributed along the circumferential direction of the cylindrical base on the outer periphery of the cylindrical base.

[0016] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0017] The motor heat dissipation connection structure of this application connects the output end of the motor and the input end of the reducer via an adapter assembly. The heat insulation component made of heat insulation material can transmit torque between the first and second adapter components, while also preventing direct contact between the first and second adapter components to significantly reduce heat transfer from the output end to the input end. This avoids significant temperature rise in the reducer, which could cause thermal expansion, hardening, or aging of the seals, ensuring the sealing effect of the seals inside the reducer. Furthermore, it prevents grease from seeping into the motor and causing short circuit damage. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The following is in conjunction with the appendix Figures 1-5 The motor heat dissipation connection structure provided in this application will be described in detail through specific embodiments and application scenarios.

[0029] Please see Figure 1 , Figure 2 and Figure 3 This application discloses a motor heat dissipation connection structure, which includes a motor 100, a reducer 200, and an adapter component 300. The adapter component 300 includes a first adapter 310, a second adapter 320, and a heat insulation component 330. The first adapter 310 and the second adapter 320 are coaxially arranged. The first adapter 310 is connected and fixed to the output end 110 of the motor 100, and the second adapter 320 is connected and fixed to the input end 210 of the reducer 200. For example, both the first adapter 310 and the second adapter 320 are columnar structures. Both the first adapter 310 and the second adapter 320 are provided with an axially penetrating through hole and a corresponding slot. The output end 110 of the motor 100 passes through the through hole of the first adapter 310 and is locked by a threaded connector. The input end 210 of the reducer 200 passes through the through hole of the second adapter 320 and is locked by a threaded connector. In this embodiment of the application, one of the first adapter 310 and the second adapter 320 is provided with an insertion recess 311, and the other is provided with an insertion protrusion 321. Exemplarily, the insertion recess 311 is provided on the first adapter 310, and the insertion protrusion 321 is provided on the second adapter 320. The insertion recess 311 and the insertion protrusion 321 are inserted into each other. The insertion recess 311 has a first sidewall and a second sidewall distributed circumferentially. When the insertion recess 311 and the insertion protrusion 321 are inserted into each other, there is an assembly gap between the first sidewall and the second sidewall and the insertion protrusion 321. A portion of the heat insulation member 330 is located in the assembly gap. It can be understood that a portion of the heat insulation member 330 fills the assembly gap and contacts the first sidewall, the second sidewall and the insertion protrusion 321, thereby ensuring stable torque transmission.

[0030] In this embodiment of the application, the heat insulation component 330 is a structure made of heat insulation material. For example, the heat insulation component 330 can be a structural component made of modified silicone rubber, fluororubber or polyimide material. By filling part of the heat insulation component 330 into the assembly gap, direct contact between the first adapter 310 and the second adapter 320 can be avoided, which greatly reduces the heat transfer between the output end 110 of the motor 100 and the input end 210 of the reducer 200.

[0031] Based on the above technical solution, in this embodiment of the application, the output end 110 of the motor 100 and the input end 210 of the reducer 200 are connected by a transition component 300. The heat insulation component 330, made of heat insulation material, can transmit torque between the first transition component 310 and the second transition component 320, while also preventing direct contact between the first transition component 310 and the second transition component 320 to significantly reduce heat transfer from the output end 110 to the input end 210. This avoids significant temperature rise in the reducer 200, which could cause thermal expansion, hardening, or aging of the seals, ensuring the sealing effect of the seals inside the reducer 200. In turn, it prevents grease inside the reducer 200 from seeping into the motor 100 and causing short circuit damage to the motor.

[0032] In this embodiment, the heat insulation component 330 can be an integral structural component; for details, please refer to [link to relevant documentation]. Figure 4 The heat insulation component 330 includes an annular base 331 and a plurality of insulating portions 332 connecting the annular base 331. The plurality of insulating portions 332 are connected to the outer periphery of the annular base 331 and are distributed along the circumference of the annular base 331. Each insulating portion 332 is used for assembly within an assembly gap. It should be noted that in the actual assembly process of the adapter assembly 300, the first adapter 310 can be used as the assembly base. Specifically, the middle part of the first adapter 310 forms a receiving space communicating with the insertion recess 311. This receiving space is used to accommodate the annular base 331. In the specific assembly, the heat insulation component 330 can be first assembled to the first adapter 310 along the axial direction of the adapter assembly 300, and then the second adapter 320 can be axially inserted and mated with the first adapter 310. At this time, the heat insulation component 330 is limited between the first adapter 310 and the second adapter 320.

[0033] In this embodiment, when the motor 100 rotates and transmits torque to the reducer 200 through the adapter 300, the insulating portion 332 is under pressure. Based on this, the insulating portion 332 can be a columnar structure connected to the outer periphery of the annular base 331. In some optional embodiments, the cross-section of the insulating portion 332 perpendicular to the axial direction of the heat insulation member 330 can be circular. The axisymmetric characteristic of the circular cross-section allows for isotropic stress distribution during torque transmission, avoiding local stress concentration and extending the service life of the heat insulation member 330. For other optional embodiments, please refer to... Figure 4 The cross section of the insulating part 332 perpendicular to the axial direction of the heat insulation member 330 can be spindle-shaped. The design of the insulating part 332, which is thick in the middle and thin at both ends, can effectively increase the extrusion contact area and allow the transmission of higher torque.

[0034] In the embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 5 The motor heat dissipation connection structure also includes a mounting base 400, which is located between the motor 100 and the reducer 200. Both the motor 100 and the reducer 200 are connected and fixed to the mounting base 400. The adapter component 300 is located inside the mounting base 400. The output end 110 of the motor 100 and the input end 210 of the reducer 200 both extend into the mounting base 400. On the one hand, the mounting base 400 can serve as the mounting base for the motor 100 and the reducer 200. On the other hand, the mounting base 400 can play a heat dissipation role to a certain extent, reducing the heat conduction between the motor housing and the reducer housing, and further improving the heat dissipation performance of the entire motor heat dissipation connection structure. For example, the mounting base 400 can be a structural component made of aluminum alloy.

[0035] In this embodiment, the mounting base 400 includes a cylindrical base 410, a first mating plate 420, and a second mating plate 430. The first mating plate 420 and the second mating plate 430 are respectively disposed at both ends of the cylindrical base 410 in the axial direction. For example, the cylindrical base 410, the first mating plate 420, and the second mating plate 430 can be coaxially and integrally connected. The motor 100 is connected to the first mating plate 420 through a threaded connector, and the reducer 200 is connected to the second mating plate 430 through a threaded connector. Based on the axial extension of the cylindrical base 410, while ensuring that the output end 110 is connected to the input end 210, the mounting base 400 also has a certain heat dissipation surface area, thereby reducing the heat conduction between the motor housing and the reducer housing.

[0036] In a further technical solution, an opening 411 penetrating the cylindrical base 410 is provided on the side wall of the cylindrical base 410. The opening 411 is correspondingly provided with the aforementioned adapter 300. On the one hand, the operator can directly contact the adapter 300 through the opening 411 to perform operations such as connection, fixation and alignment. On the other hand, the opening 411 can also form a natural ventilation path, and the hot air inside the cylindrical base 410 can escape to the outside through the opening 411, further reducing the temperature of the output end 110 of the motor 100, the input end 210 of the reducer 200 and the adapter 300.

[0037] In an optional embodiment of this application, the length of the opening 411 in the axial direction of the cylindrical base 410 is greater than the length of the adapter 300, and the width of the opening 411 in the circumferential direction of the cylindrical base 410 is greater than the diameter of the adapter 300. That is to say, the cross-sectional dimension of the longitudinal section of the adapter 300 is smaller than the opening dimension of the opening 411. In this way, the design of the larger opening 411 can ensure that the operator has enough operating space to realize the connection and fixation of the first adapter 310 and the second adapter 320, and at the same time, it can further improve the heat dissipation effect.

[0038] As mentioned above, the mounting base 400 is connected between the motor 100 and the reducer 200, and can play a certain role in heat conduction and heat dissipation for the motor housing, thereby reducing the heat conducted to the reducer 200. In a further technical solution, the mounting base 400 also includes multiple heat sinks (not shown in the figure) connected to the cylindrical base 410. The multiple heat sinks are distributed along the circumferential direction of the cylindrical base 410 on the outer periphery of the cylindrical base 410. The arrangement of the heat sinks can significantly increase the heat dissipation surface area of ​​the mounting base 400 and accelerate the dissipation of heat.
