Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a cooling speed reducer. Background Technology

[0002] A worm gear reducer is a mechanical device that transmits power through gear speed conversion. Its core function is to reduce the rotational speed of a motor to the required speed and output a larger torque.

[0003] In worm gear drives, the worm gears remain meshed and constantly agitate the lubricating oil. After prolonged operation, the friction between components and the energy conversion generate a large amount of heat, causing the internal temperature of the reducer to rise. Since lubricating oil loses its lubricity when its temperature exceeds a certain level, the lubrication effect is significantly reduced. Therefore, reducing the reducer temperature is an essential measure. To this end, we propose a cooling-type reducer. Utility Model Content

[0024] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1 to 7 This utility model provides a technical solution: a cooling type speed reducer, including a motor 1 and a speed reducer, wherein the speed reducer is a worm gear speed reducer, and the worm gear speed reducer specifically includes a housing 7, as shown below. Figure 2 and Figure 4 As shown, multiple mounting bases are provided at the bottom of the housing 7 to fix the reducer. A worm gear 25 is provided inside the housing 7 and is mounted on the drive shaft 10. Both ends of the drive shaft 10 are rotatably connected to the housing 7. A worm 18 is meshed on one side of the worm gear 25. The worm 18 is parallel to the central axis of the motor 1 and its two ends are rotatably connected to the housing 7. The housing 7 is provided with lubricating oil to lubricate the worm gear and worm. However, long-term operation will cause the lubricating oil temperature to rise. This application is a solution designed to cool the lubricating oil.

[0026] Motor 1 is mounted on the reducer via a support mechanism, and motor 1 is connected to the input end of the reducer via a transmission device. The support mechanism and the transmission device are described in detail below: First, the support mechanism is introduced. The support mechanism includes a mounting flange 2, which is located at the edge of the motor 1 near its shaft. The edge of the mounting flange 2 is provided with multiple feet 19, which are all mounted on the support plate 3. The feet 19 are fastened to the support plate 3 with bolts. The support plate 3 is mounted on the transmission device.

[0027] Next, the transmission device is introduced. The transmission device includes a sealing shell 13 located at the input end of the reducer (specifically, one end of the worm gear 18). The support plate 3 is installed on the side of the sealing shell 13 away from its opening, so that the support plate 3 and the sealing shell 13 can form an integral structure. The support plate 3 is only used to support the motor 1. A second gear 21 is provided inside the sealing housing 13. The second gear 21 is mounted on the connecting shaft 22, which is coaxial with the motor 1 and rotatably mounted on the sealing housing 13. The connecting shaft 22 is connected to the rotating shaft of the motor 1. To facilitate the connection of the connecting shaft 22 to the rotating shaft of the motor, as follows... Figure 6 As shown, a connecting sleeve 15 is coaxially provided on the rotating shaft of motor 1. The connecting sleeve 15 is coaxial with the connecting shaft 22, and the connecting sleeve 15 is fitted on the connecting shaft 22. The two are connected by a key to achieve power connection. In this way, the connecting shaft 22 and the rotating shaft of motor 1 can be connected by plugging and unplugging, which is convenient for installation and disassembly. like Figure 3 and Figure 6 As shown, a first gear 17 corresponding to the second gear 21 is provided on the input end of the reducer (specifically, one end of the worm gear 18). When the sealing shell 13 is installed on the reducer, the first gear 17 meshes with the second gear 21. This allows the motor 1 to drive the second gear 21 and the connecting shaft 22 to rotate, and the second gear 21 to drive the first gear 17 to rotate. The diameter of the first gear 17 is larger than the diameter of the second gear 21, which increases the output torque of the motor. Then, the first gear 17 continues to drive the worm gear to rotate.

[0028] Furthermore, a fan housing 11 with a flow port 5 is installed on one side of the support mechanism. Specifically, the fan housing 11 is located on the side of the support plate 3. One end of the fan housing 11 is equipped with a blower 6, and a heat exchange pipe 8 is bent inside the blower 6. The heat exchange pipe 8 is an aluminum pipe, copper pipe, or other heat-conducting pipe. The other end of the fan housing 11 is rotatably equipped with a mounting shaft 14. Figure 7 As shown, a fan wheel 24 is provided on the mounting shaft 14 located inside the fan housing 11. When the mounting shaft 14 rotates, the mounting shaft 14 can drive the fan wheel 24 to rotate. The fan wheel 24 and the fan housing 11 can form a fan. The position of the blower 6 is equivalent to the inlet of the fan, so the outside air can continuously enter the blower 6 and then flow out from the flow port 5. A pump body 12 is also provided on one side of the support mechanism. Specifically, the pump body 12 is located on the side of the support plate 3. The rotating shaft of the pump body 12, the rotating shaft of the motor 1, and the mounting shaft 14 are connected by a belt drive mechanism. Figure 1As shown, the belt drive mechanism includes pulleys mounted on the rotating shaft of the pump body 12, the rotating shaft of the motor 1, and the end of the mounting shaft 14 away from the fan housing 11. The pulleys are connected by a belt. It should be emphasized that the distance between the support legs 19 must be sufficient for the belt to pass through to avoid contact between the belt and the support legs 19. So when the motor 1 rotates, it can simultaneously drive the pump body 12 and the mounting shaft 14 to rotate. The pulleys on the rotating shaft of the pump body 12, the rotating shaft of the motor 1, and the end of the mounting shaft 14 can be of different sizes, so that different transmission ratios can be achieved, and the rotational speeds of the pump body 12 and the mounting shaft 14 can be different. It should also be noted that the output speed of motor 1 is reduced by the reducer, so the output speed of motor 1 is much higher than that of the reducer. Therefore, the speed of pump body 12 and mounting shaft 14 can be adjusted by designing the size of the pulley to meet the speed requirements.

[0029] Pump body 12 is an impeller pump or gear pump. When pump body 12 rotates, it drives the oil inside to circulate. Therefore, the outlet of pump body 12 is connected to one end of heat exchange pipe 8 through a pipe, and the other end of heat exchange pipe 8 and the inlet of pump body 12 are respectively connected to the reducer through pipes. Figure 1 and Figure 2 As shown, pipe interfaces 9 are provided on both the upper and lower sides of the housing 7. The pipe interfaces 9 are connected to pipes respectively. In this way, the pump body 12 can drive the lubricating oil inside the housing 7 to the heat exchange tube 8. Since the heat exchange tube 8 is located in the blower 6, there is a fast airflow in the blower 6. Therefore, the lubricating oil can be heat exchanged when it passes through the blower 6, so that the temperature of the lubricating oil is reduced and high temperature is avoided.

[0030] Furthermore, supports are provided on the sides of both the pump body 12 and the fan casing 11. In order to facilitate the installation of the pump body 12 and the fan casing 11, a mounting seat 23 is provided on one side of the support plate 3. Both the fan casing 11 and the pump body 12 are mounted on the mounting seat 23, that is, the supports of both are fastened to the mounting seat 23 by bolts.

[0031] Furthermore, the end of the fan housing 11 away from the blower duct 6 is detachably provided with an end cover 4. The end cover 4 is fastened to the fan housing 11 by bolts. The mounting shaft 14 is rotatably installed at the center of the end cover 4. When the end cover 4 is removed, the mounting shaft 14 can be taken out from the fan housing 11, which facilitates maintenance and cleaning of the fan housing 11 and the blower duct 6.

[0032] Based on the above embodiments, further optimizations can be made, such as... Figure 3 and Figure 6As shown, an oil inlet 16 is provided on the side of the reducer around the first gear 17. The oil inlet 16 communicates with the inside of the sealing shell 13, allowing the lubricating oil in the reducer to flow into the sealing shell 13 to lubricate the first gear 17 and the second gear 21. Furthermore, a connecting edge 20 is provided on the edge of the sealing shell 13 near its opening. The connecting edge 20 is detachably connected to the side of the reducer, that is, the two are fastened together by bolts.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
