Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a speed reducer that facilitates heat dissipation. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm gear drives, or gear and worm gear drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine. It plays a role in matching speeds and transmitting torque between the prime mover and the driven machine or actuator, and its applications are extremely widespread in modern machinery.

[0003] Gearboxes generate a lot of heat during use, but most gearboxes are not equipped with heat dissipation functions, only with a housing. However, the heat dissipation performance of the housing is not sufficient for the long-term use of the gearbox, posing certain safety hazards and causing damage to internal components due to prolonged high temperatures.

[0004] Traditional speed reducers often employ relatively simple heat dissipation methods, resulting in low efficiency and difficulty in meeting the heat dissipation requirements of long-term continuous operation or high-load operation. Moreover, speed reducers typically operate in complex industrial environments, where dust and other impurities can easily enter the reducer through the heat dissipation channels, causing wear and corrosion to the internal transmission components and further reducing the reliability and stability of the speed reducer. Utility Model Content

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] 1. This utility model, by setting up a heat dissipation component, utilizes the rotation of the input shaft to drive a series of gear transmissions, thereby driving the fan blades to rotate and generate airflow.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] Reference Figures 1-5 A heat-dissipating speed reducer includes a speed reducer housing 1, within which an input shaft 2 is rotatably connected. It should be noted that the speed reducer is equipped with a motor, and the motor and input shaft 2 are connected via a coupling. This connection effectively transmits the torque output by the motor, ensuring that the input shaft 2 rotates smoothly and accurately according to the motor's speed, thereby driving the worm gear 3 to rotate, thus enabling the normal operation of the entire speed reducer. In practical applications, a suitable coupling can be selected based on the specific working requirements and load conditions of the speed reducer, such as a flexible coupling. This coupling not only transmits torque but also, to a certain extent, buffers the impact generated during motor start-up and stop, protecting the internal transmission components of the speed reducer. Since this method is existing technology in the field and is only partially applicable, it will not be described in detail here.

[0041] A worm gear 3 is fixedly sleeved on the input shaft 2. An output shaft 4 is rotatably connected inside the reducer housing 1. A worm wheel 5 is fixedly sleeved on the output shaft 4. The worm wheel 5 meshes with the worm gear 3. A mounting frame 7 is installed on the side wall of the reducer housing 1. The side wall of the reducer housing 1 has a recess for easy installation of the mounting frame 7. The mounting frame 7 is fixedly connected to the recess on the side wall of the reducer housing 1 by bolts. The mounting frame 7 is U-shaped and hollow inside. A dustproof mesh plate 8 is snapped into the mounting frame 7. The side wall of the dustproof mesh plate 8 is... The trapezoidal inclined design matches the inclined surface of the insert 75. When it enters the mounting frame 7, the inclined surface will touch and drive the insert 75 to slide into the through hole 71, avoiding obstruction and affecting installation. The mesh diameter of the dustproof mesh plate 8 is set between 0.5-1mm, which can effectively block most dust particles, debris and other impurities in the industrial environment from entering the mounting frame 7, thereby preventing them from entering the reducer housing, and will not cause too much obstruction to the airflow generated by the heat dissipation components.

[0042] The heat dissipation assembly is used to dissipate the heat generated during the operation of the worm gear 5 and worm 3. The assembly includes a driving gear 6, a rotating shaft 63, a driven gear 61, a rotating gear 62, and fan blades 64. The driving gear 6 is fixed to the input shaft 2. The rotating shaft 63 is rotatably connected to the side wall of the reducer housing 1. The driven gear 61 and rotating gear 62 are fixed to the rotating shaft 63, and the fan blades 64 are fixed to the rotating gear 62. The rotating shaft 63 has three driven gears 61 and three rotating gears 62, and the number of fan blades 64 corresponds to the number of rotating shafts 63. The driven gear 61 is in the same vertical direction as the driving gear 6 and meshes with it. There are two rotating gears 62, symmetrically arranged about the axis of the driven gear 61, and both mesh with it. This design allows the multiple fan blades 64 to rotate synchronously, thus achieving a more effective heat dissipation effect.

[0043] The disassembly and assembly assembly is used for disassembling and installing the dustproof mesh plate 8. The assembly includes a through hole 71, a spring 72, a T-shaped rod 73, a pull rod 74, an insert block 75, and a slot 81. The through holes 71 are symmetrically located on opposite sides of the mounting frame 7. The spring 72 is fixed to the top surface of the mounting frame 7. The T-shaped rod 73 is embedded in the middle of the spring 72. The end of the spring 72 furthest from the mounting frame 7 is fixedly connected to the inner top surface of the T-shaped rod 73. The spring 72 ensures a sufficiently tight fit between the insert block 75 and the slot 81, guaranteeing that the dustproof mesh plate 8 is securely installed within the mounting frame 7 and will not loosen or fall off due to vibrations during the operation of the reducer. The pull rod 74 is fixed to the top of the T-shaped rod 73. On the surface, the insert 75 is fixed to the bottom surface of the T-shaped rod 73, and the slot 81 is opened on the top surface of the dustproof mesh plate 8. There are two slots 81 symmetrically arranged. The insert 75 is inserted into the slot 81, and the T-shaped rod 73 is placed in the through hole 71 and moves. This design not only ensures the linear movement trajectory of the T-shaped rod 73 during operation, so that the insert 75 can be accurately inserted into or pulled out of the slot 81, but also plays a certain limiting role for the T-shaped rod 73 to prevent it from deviating in the horizontal direction, thereby ensuring the normal operation of the disassembly and assembly components and improving the reliability and accuracy of the disassembly and assembly of the dustproof mesh plate 8. The insert 75 is set corresponding to the slot 81, and the shape of the insert 75 matches the shape of the slot 81.

[0044] The functional principle of this utility model can be explained through the following operation methods:

[0045] When the input shaft 2 of the reducer rotates, the drive gear 6 fixed on the input shaft 2 rotates accordingly. Since the drive gear 6 meshes with the driven gear 61, the drive gear 6 drives the driven gear 61 to rotate, which in turn drives the rotating shaft 63 fixed with the driven gear 61 to rotate. The rotating gear 62 fixed on the rotating shaft 63 rotates with the rotating shaft 63, and the rotating gear 62 meshes with two other rotating gears 62 respectively, so that these two rotating gears 62 also rotate synchronously. Finally, the fan blades 64 fixed on the rotating gears 62 rotate. During the rotation of the fan blades 64, airflow is generated, which dissipates the heat generated during the operation of the reducer in a timely manner, thus playing a good heat dissipation role.

[0046] When the dustproof mesh panel 8 needs to be disassembled, cleaned, or replaced, by pulling the pull rod 74, the pull rod 74 moves the T-shaped rod 73 upward into the through hole 71. At this time, the spring 72 is compressed, and the insert 75 at the bottom of the T-shaped rod 73 is pulled out from the slot 81 at the top of the dustproof mesh panel 8, so that the dustproof mesh panel 8 can be easily removed from the mounting frame 7. During installation, the dustproof mesh panel 8 is placed in the mounting frame 7, and then the pull rod 74 is released. Under the elastic force of the spring 72, the T-shaped rod 73 moves downward, and the insert 75 is inserted into the corresponding slot 81, realizing the quick installation of the dustproof mesh panel 8.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
