DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a speed reducer with stable transmission, including a speed reducer main body 100. The speed reducer main body 100 includes a speed reducer housing 101. A fixed bottom plate 103 is integrally formed at the bottom end of the speed reducer housing 101. Fixing holes 105 are opened at both ends of the fixed bottom plate 103. One end of the speed reducer housing 101 is provided with a motor 102. A transmission shaft 104 is provided on the front surface of the speed reducer housing 101. The speed reducer main body 100 is fixedly installed at the position where it is used. And after the speed reducer main body 100 is fixedly installed, the end of the transmission shaft 104 is fixedly installed and reinforced with an external driving end again. And when the motor 102 operates to drive the inside of the speed reducer housing 101, the transmission shaft 104 is driven to operate. The speed reducer main body 100 is further provided with:

[0026] A heat dissipation mechanism, and the heat dissipation mechanism includes a water storage component arranged on the upper surface of the speed reducer housing 101. A heat dissipation component is arranged inside the speed reducer housing 101. A water return component is arranged on one side of the water storage component. When the speed reducer main body 100 generates heat inside the speed reducer housing 101 during use, the heat generated inside the speed reducer housing 101 can be dissipated by the heat dissipation mechanism. Effective heat dissipation treatment during long-term operation improves the convenience of heat dissipation when the speed reducer main body 100 is in use and extends the service life of the speed reducer main body 100.

[0027] In order to facilitate high-pressure water circulation and water inlet for heat dissipation through the water storage component, in this embodiment, preferably, the water storage component includes a water storage tank 1011 fixed to the top end of the speed reducer housing 101 through mounting bolts. A high-pressure pump 1016 is fixedly installed on the upper surface of the water storage tank 1011 through mounting bolts. A water outlet pipe 1015 is arranged at the connection between the front surface of the high-pressure pump 1016 and the water storage tank 1011. A connecting pipe three 1014 is arranged on the upper surface of the high-pressure pump 1016. The high-pressure pump 1016 operates to make the water inside the water storage tank 1011 enter the inside of the connecting pipe three 1014 through the water outlet pipe 1015. After the water enters the inside of the connecting pipe three 1014, it enters the inside of the heat dissipation channel 1018 at one end of the speed reducer housing 101.

[0028] In order to facilitate the heat dissipation of the heat generated inside the reducer housing 101 through the heat dissipation component and make the heat dissipation process convenient, in this embodiment, preferably, the heat dissipation component includes a heat dissipation channel 1018 opened at one end of the reducer housing 101 and inside the rear surface and the upper surface. One end of the heat dissipation channel 1018 is hermetically fixed to the end of the connecting pipe three 1014. At the connection of the two heat dissipation channels 1018 on one side of the reducer housing 101 at the tail end of the reducer housing 101, a connecting pipe one 1012 is hermetically fixed. At the connection of the two heat dissipation channels 1018 on the rear surface and the upper surface of the reducer housing 101, a connecting pipe two 1013 is hermetically fixed. After water enters the inside of the connecting pipe three 1014, it flows into the heat dissipation channel 1018 inside one end of the reducer housing 101, and then enters the heat dissipation channel 1018 inside the rear surface of the reducer housing 101 through the connecting pipe one 1012 until it enters the heat dissipation channel 1018 inside the top end of the reducer housing 101 through the connecting pipe two 1013, which facilitates the internal circulating water flow heat dissipation treatment of the heat dissipation channel 1018.

[0029] In order to facilitate the re-entry into the inside of the water storage tank 1011 after the first cycle of heat dissipation through the water return component, in this embodiment, preferably, the water return component includes a water return pipe 1017 installed at the connection of one side of the water storage tank 1011 and one end of the heat dissipation channel 1018 at the top of the reducer housing 101, and the water return pipe 1017 extends into the inside of the water storage tank 1011. After the first cycle of water heat dissipation treatment, the water inside the heat dissipation channel 1018 can be returned to the inside of the water storage tank 1011 through the water return pipe 1017 for collection.

[0030] A strengthening and fixing mechanism, and the strengthening and fixing mechanism includes a strengthening and fixing component arranged inside the fixing base plate 103 at the bottom end of the fixing hole 105. The end of the strengthening and fixing component is provided with a pushing component, and a screwing-in and squeezing fixing component is arranged at the connection of the inner surface of the pushing component and the fixing base plate 103. When the reducer main body 100 is installed and the fixing bolt penetrates through the inside of the fixing hole 105 for fixing, the strengthening and fixing mechanism strengthens the fixing and installation of the fixing base plate 103 and the reducer main body 100. When the driving operation generates vibration and is affected by external forces, it is not easy to cause the bolt and the reducer main body 100 to loosen, and it is still more stable to install and drive, so that the reducer main body 100 is more stable in transmission operation after installation, and the strengthening and fixing performance and transmission stability of the reducer main body 100 during use are improved.

[0031] In order to facilitate the installation of the fixing bolt through the inside of the fixing hole 105 and strengthen the fixing and installation by strengthening the fixing component, in this embodiment, preferably, the strengthening fixing component includes a moving adjustment groove 1051 opened at the bottom end of the fixing hole 105 inside the fixing base plate 103. One end inside the moving adjustment groove 1051 is welded with an internal thread abutting plate 1055, and the other end inside the moving adjustment groove 1051 is provided with an arc plate 1052. Two tooth engagement plates 1053 are welded on the inner surface of the arc plate 1052. When the fixing bolt rotates inside the fixing hole 105, it can be threadedly installed and abutted against the inner surface of the internal thread abutting plate 1055, and the arc plate 1052 and the tooth engagement plates 1053 move and clamp on the surface of the fixing bolt for strengthening installation.

[0032] In order to facilitate the movement of the arc plate 1052 and the tooth engagement plates 1053 to move and clamp the surface of the fixing bolt for strengthening installation through the pushing component, in this embodiment, preferably, the pushing component includes a U-shaped pushing frame 1054 movably connected to the surface of the fixing base plate 103. The end of the U-shaped pushing frame 1054 is fixedly welded to the end of the arc plate 1052, which is easy to move the U-shaped pushing frame 1054 to drive the arc plate 1052 and the tooth engagement plates 1053 to move for strengthening installation.

[0033] In order to facilitate the movement of the U-shaped pushing frame 1054 to drive the arc plate 1052 and the tooth engagement plates 1053 to move for strengthening installation through the screwing-in and squeezing fixing component, in this embodiment, preferably, the screwing-in and squeezing fixing component includes a rotating body 1056 rotatably connected to the middle position inside the U-shaped pushing frame 1054 through a rotating groove. The end of the rotating body 1056 is integrally formed with a threaded push rod 1057. An internal hexagonal card slot 1050 is provided at the tail end edge of the threaded push rod 1057, which is convenient for a wrench to be clamped inside the internal hexagonal card slot 1050 to drive its rotation adjustment. It is convenient for the end of the threaded push rod 1057 to rotate in place inside the U-shaped pushing frame 1054 through the rotating body 1056 when rotating. A locking nut 1059 is rotated at the end of the threaded push rod 1057. An internal threaded hole 1058 is opened on the front surface of the fixing base plate 103. The threaded push rod 1057 is threadedly rotated and connected to the inside of the internal threaded hole 1058 until the other end of the threaded push rod 1057 is rotated and pushed outside the internal threaded hole 1058 to drive the U-shaped pushing frame 1054. The U-shaped pushing frame 1054 moves to drive the arc plate 1052 and the tooth engagement plates 1053 to move and clamp, and finally the locking nut 1059 is rotated to strengthen the installation and use of the threaded push rod 1057.

[0034] Working principle and usage process of the present invention: When using this reducer with stable transmission, the reducer main body 100 is directly placed at the installation position through the fixed bottom plate 103. The fixing bolts pass through the inside of the fixing holes 105 to fix the fixed bottom plate 103, thereby fixing the installation of the reducer main body 100 at the usage position. After the reducer main body 100 is fixedly installed, the end of the transmission shaft 104 is further fixedly installed with the external driving end. When the motor 102 operates to drive the inside of the reducer housing 101, the transmission shaft 104 is driven to rotate, and when the transmission shaft 104 rotates, it drives the external equipment to perform driving operations;

[0035] Then, when the reducer main body 100 is fixedly installed, when the fixing bolt rotates and installs inside the fixing hole 105, the fixing bolt continues to rotate and is rotationally connected to the inner surface of the internal thread abutting plate 1055. After the fixed installation, an external wrench is again engaged inside the internal hexagonal card slot 1050 to drive the threaded push rod 1057 to rotate inside the internal thread hole 1058. When the threaded push rod 1057 rotates, its end rotates through the rotating body 1056 inside the U-shaped push frame 1054, so that when the threaded push rod 1057 rotates outward, it pushes the U-shaped push frame 1054. When the U-shaped push frame 1054 is pushed, it drives the arc plate 1052 and the tooth engaging plate 1053 to move until the tooth engaging plate 1053 engages with the surface of the fixing bolt for reinforcement installation. Then, the locking nut 1059 is rotated again to reinforce the installation of the threaded push rod 1057. Therefore, after the reducer main body 100 is installed, its fixed installation is strengthened. When the reducer main body 100 vibrates due to external forces during the installation and driving operations, it is not easy for the bolts and the reducer main body 100 to become loose, and it is still more stable for installation and transmission use, making the reducer main body 100 more stable for transmission operations after installation, and improving the strengthening fixity and transmission stability of the reducer main body 100 during use;

[0036] Finally, when the reducer main body 100 is used after installation and heat is generated inside the reducer housing 101 during long-term use, water can be injected and filled in the interior of the water storage tank 1011. During heat dissipation, the high-pressure pump 1016 operates to allow the water inside the water storage tank 1011 to enter the interior of the third connecting pipe 1014 through the water outlet pipe 1015. After the water enters the interior of the third connecting pipe 1014, it flows into the heat dissipation channel 1018 inside one end of the reducer housing 101, and then enters the heat dissipation channel 1018 inside the rear surface of the reducer housing 101 through the first connecting pipe 1012 again, until it enters the heat dissipation channel 1018 inside the top end of the reducer housing 101 through the second connecting pipe 1013, facilitating the circulating water flow inside the heat dissipation channel 1018. Finally, it returns to the interior of the water storage tank 1011 again through the water return pipe 1017, enabling the heat inside the water storage tank 1011 to be taken away by the circulating water flow inside when heat is generated inside the reducer housing 101, facilitating rapid heat dissipation inside, effectively dissipating heat during long-term operation, improving the convenience of heat dissipation when the reducer main body 100 is in use, and extending the service life of the reducer main body 100.
