Description

Technical Field

[0001] This utility model relates to the field of gear reduction motor technology, specifically to an integrated air-cooled gear reduction motor housing. Background Technology

[0002] Gear reducers typically reduce the speed of a motor, internal combustion engine, or other high-speed power source by using a small gear on the input shaft of a gear reducer or gearbox to drive a larger gear. By employing a multi-stage structure, the rotational speed can be significantly reduced, thereby increasing the output torque of the geared motor. Its core "force amplification and speed reduction" function utilizes multiple stages of gear transmission to achieve speed reduction. The reducer itself consists of multiple gear pairs. Due to its compact design, gear reducer motors save space while possessing high power transmission capacity, achieving efficiencies exceeding 95%, low energy consumption, and superior performance.

[0003] However, certain defects and shortcomings still exist and need to be optimized. The specific defects and shortcomings are as follows: The housing of the existing gear reducer motor is not reasonably designed, lacks an effective heat dissipation channel or has insufficient heat dissipation area, resulting in the inability to effectively dissipate heat and low heat dissipation efficiency. During operation, the gear reducer generates a lot of heat. The accumulation of heat will cause the temperature of the gear reducer to rise, exceeding its temperature limit, and even causing thermal shock, leading to gear reducer failure. Therefore, it is necessary to design an integrated air-cooled heat dissipation gear reducer motor housing to solve the problems mentioned in the background technology. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] This utility model provides an integrated air-cooled gear reducer motor housing. This integrated air-cooled gear reducer motor housing improves the existing gear reducer motor housing design by integrating the air-cooling mechanism with the gear reducer motor housing, increasing the heat dissipation channel and heat dissipation area, ensuring that heat can be effectively dissipated, improving heat dissipation efficiency, simplifying the equipment structure, and reducing production costs, thereby solving the problems mentioned in the background art.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] An integrated air-cooled gear reducer motor housing includes a gear reducer motor housing body 1 and a gear reducer motor housing heat sink 2. The gear reducer motor housing body 1 is integrally formed by a body 11 and a rear end cover 12. Several sets of conical heat sink fins 13 arranged in a ring are fixedly installed on the outer surface of the gear reducer motor housing body 1. Any two sets of conical heat sink fins 13 arranged in a ring are provided with concave arc-shaped heat dissipation channels 14. The heat dissipation area and heat dissipation channels of the gear reducer motor housing body 1 can be increased by using the conical and concave arc-shaped structural design.

[0024] A heat sink 2 for the gear reducer motor housing 1 is fixedly installed at the end of the housing body 1 away from the connected equipment.

[0025] The gear reducer motor housing heat sink 2 includes a main housing 21 and a cover 22. The main housing 21 has corresponding heat dissipation windows 211 near each set of concave arc-shaped heat dissipation channels 14. The main housing 21 has a circulating air chamber 212 inside, and a cooling fan 213 is movably installed inside the circulating air chamber 212. The air inside the circulating air chamber 212 is continuously drawn out from the heat dissipation windows 211 under the action of the cooling fan 213 and flows inside each set of concave arc-shaped heat dissipation channels 14 from one end to the other. At the same time, the flow carries away the heat on the conical heat dissipation fins 13 and the concave arc-shaped heat dissipation channels 14. The continuous circulation makes the heat dissipation effective, greatly improves the heat dissipation efficiency, prevents the heat accumulation inside the gear reducer motor and affects the performance. In addition, the heat dissipation windows 211 can increase the heat dissipation channel on the one hand, and can also divide the air to ensure the uniformity of heat dissipation and avoid local overheating, so as to achieve better results.

[0026] Furthermore, in this embodiment, please refer to Figure 1 , Figure 2 and Figure 3The outer surface of the main body 11 is provided with several groups of first conical heat dissipation segments 111 arranged in a ring. A first inner arc-shaped heat dissipation groove 112 is opened between any two groups of the several groups of first conical heat dissipation segments 111. The outer surface of the rear end cover 12 is provided with several groups of second conical heat dissipation segments 121 arranged in a ring. A second inner arc-shaped heat dissipation groove 122 is opened between any two groups of the several groups of second conical heat dissipation segments 121. The conical heat dissipation fins 13 are composed of the first conical heat dissipation segments 111 and the second conical heat dissipation segments 121. The concave arc-shaped heat dissipation channel 14 is composed of the first inner arc-shaped heat dissipation groove 112 and the second inner arc-shaped heat dissipation groove 122. The design of the first conical heat dissipation segments 111, the first inner arc-shaped heat dissipation groove 112, the second conical heat dissipation segments 121, and the second inner arc-shaped heat dissipation groove 122 makes the structure of the gear reducer motor housing 1 more regular, coordinated and beautiful, convenient to process, and conducive to increasing the effective heat dissipation area and heat dissipation channel.

[0027] Furthermore, in this embodiment, please refer to Figure 2 , Figure 3 and Figure 4 The main body 11 has an assembly cavity 113 inside. A bearing seat 123 is installed through the center of the rear end cover 12. A shaft hole 1231 is installed through the inside of the bearing seat 123. A mechanical seal ring 1232 is fixedly installed around the inner wall of the shaft hole 1231. A rotor connecting shaft 2131 is fixedly installed at the center of one end of the cooling fan 213 near the rear end cover 12. The rotor connecting shaft 2131 passes through the inside of the shaft hole 1231 and is keyed to the motor rotor. The design of the rotor connecting shaft 2131 allows the cooling fan 213 to be connected to the motor rotor. The cooling is carried out simultaneously with the operation of the gear reducer motor, which is energy-saving and effective. The design of the bearing seat 123 and the mechanical seal ring 1232 ensures that dust can be prevented from entering the interior of the gear reducer motor during the stable and reliable operation of the cooling fan 213.

[0028] Furthermore, in this embodiment, please refer to Figure 4 The main cover 21 has conical blocks 214 fixedly installed around its side closest to the gear reducer motor housing 1, corresponding to several sets of conical heat dissipation fins 13 arranged in a ring. The main cover 21 has several sets of perforated mounting ears 215 arranged in a ring around its side away from the gear reducer motor housing 1. The cover 22 is fixedly connected to the perforated mounting ears 215 arranged in a ring by multiple sets of fixing bolts 221. Several sets of air holes 222 are opened through the center of the cover 22. The design of the conical blocks 214 facilitates the fixed installation of the main cover 21 and the gear reducer motor housing 1 while effectively avoiding obstruction of the heat dissipation channel. At the same time, the design of the perforated mounting ears 215 allows the cover 22 and the main cover 21 to be fixedly connected for subsequent maintenance of the heat dissipation components.

[0029] In this embodiment, the specific implementation scenario is as follows: the gear reducer motor is working, and the cooling fan 213 starts to run under the action of the rotor. At this time, the external air enters the interior of the circulating air chamber 212 through the air holes 222 on the cover 22. At the same time, the air inside the circulating air chamber 212 is continuously discharged from the heat dissipation window 211 under the action of the cooling fan 213, and flows inside each set of concave arc-shaped heat dissipation channels 14 from one end to the other. During the flow, the heat on the conical heat dissipation fins 13 and the concave arc-shaped heat dissipation channels 14 is carried away. The continuous circulation makes the heat dissipation effective, greatly improving the heat dissipation efficiency, preventing the accumulation of heat inside the gear reducer motor and affecting the performance. Moreover, compared with the existing gear reducer motor housing, the overall design increases the heat dissipation channel and heat dissipation area, ensuring that the heat can be effectively dissipated and improving the heat dissipation efficiency. Furthermore, by integrating the air-cooled heat dissipation mechanism with the gear reducer motor housing, the equipment structure is simplified and the production cost is reduced.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
